Hereinafter, a specific aspect of the present invention will be described with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

[Embodiment 1]
FIG. 1 is a block diagram showing a schematic configuration of a display device 100 according to the first embodiment to which the present invention is applied.
As shown in FIG. 1, the display device 100 of the first embodiment specifically includes a central control unit 1, a memory 2, an image recording unit 3, a display unit 4, an operation input unit 5, and an operation process. It is provided with a part 6.
Further, the central control unit 1, the memory 2, the image recording unit 3, the display unit 4, the operation input unit 5, and the operation processing unit 6 are connected via the bus line 7.

The central control unit 1 controls each unit of the display device 100. Specifically, although not shown, the central control unit 1 includes a CPU (Central Processing Unit) and the like, and performs various control operations according to various processing programs (not shown) for the display device 100.

The memory 2 is configured by, for example, a DRAM (Dynamic Random Access Memory) or the like, and temporarily stores data or the like processed by the central control unit 1, the operation processing unit 6, or the like.

The image recording unit 3 is composed of, for example, an SSD (Solid State Drive) or the like, and is a still image or a moving image encoded in a predetermined compression format (for example, JPEG format, MPEG format, etc.) by an image processing unit (not shown). Record image data.
The image data recorded in the image recording unit 3 may be imaged by an image pickup unit (not shown) of the display device 100, or after being imaged by an external image pickup device (not shown). It may be transferred to the display device 100 and recorded in the image recording unit 3.
Further, the image recording unit 3 may be configured such that, for example, a recording medium (not shown) is detachably configured to control reading of data from the mounted recording medium and writing of data to the recording medium.

The display unit 4 displays an image on the display screen of the display panel 4a.
That is, the display unit 4 displays a predetermined image on the display screen of the display panel (display means) 4a based on the image data of the predetermined size decoded by the image processing unit (not shown). Further, as will be described later, the display unit 4 reproduces a moving image read from the image recording unit 3 at a predetermined playback frame rate (described later) under the control of the first switching control unit 6c (described later) of the operation processing unit 6. For example, it is reproduced at 30 fps).
The display panel 4a is composed of, for example, a liquid crystal display panel, an organic EL (Electro-Luminescence) display panel, or the like, but the display panel 4a is merely an example and is not limited thereto.

The operation input unit 5 is for performing a predetermined operation of the display device 100. Specifically, the operation input unit 5 includes a power button for ON / OFF operation of the power supply, a selection determination button for selection instructions of various modes and functions, and the like (all not shown).
Then, when various buttons are operated by the user, the operation input unit 5 outputs an operation instruction corresponding to the operated button to the central control unit 1. The central control unit 1 causes each unit to perform a predetermined operation (for example, reproduction of a moving image) according to an operation instruction input from the operation input unit 5.

Further, the operation input unit 5 has a touch panel 5a provided integrally with the display panel 4a of the display unit 4.
The touch panel 5a detects the contact position of the user's finger (hand), touch pen, or the like that directly or indirectly contacts the display screen forming the display area of the display panel 4a. That is, the touch panel 5a is provided on the display screen of the display panel 4a or inside the display screen, and is displayed on the display screen by various methods such as a capacitance method, a resistance film method, and an ultrasonic surface acoustic wave method. The XY coordinates of the contact position in the above are detected at a predetermined sampling cycle. Then, the touch panel 5a outputs a position signal related to the XY coordinates of the contact position to the operation processing unit 6.

Further, the touch panel 5a is divided into a plurality of regions in a predetermined state such as during video reproduction (see FIGS. 2A and 2B).
For example, as shown in FIG. 2A, when the touch panel 5a is equally divided into two regions, the first region A1 is provided on the right side and the second region A2 is provided on the left side. .. Further, for example, as shown in FIG. 2B, when the touch panel 5a is equally divided into four regions, the first region A1 is provided on the right side and the upper side, and the second region is provided on the left side and the upper side. A2 is provided, a third region A3 is provided on the right side and the lower side, and a fourth region A4 is provided on the left side and the lower side.
As a plurality of regions for dividing the touch panel 5a, those shown in FIGS. 2 (a) and 2 (b) are examples, and the number, shape, arrangement, and the like of the regions can be arbitrarily changed. For example, the number of regions may be an odd number, and the plurality of regions may have different shapes, areas, and the like.

Further, the plurality of regions that divide the touch panel 5a are associated with different switching directions in the switching display processing by the first switching control unit 6c (described later) of the operation processing unit 6, for example.
Here, the switching direction means, for example, when the display target is a moving image, the feeding direction of a plurality of frame images constituting the moving image, and examples thereof include a forward direction and a reverse direction.
Specifically, for example, when the touch panel 5a is divided into two regions, a first region A1 and a second region A2 (see FIG. 2A), the first region A1 has a forward direction as a switching direction. The second region A2 is associated with the second region A2 in the opposite direction as the switching direction. As will be described later, in the switching display process by the first switching control unit 6c, the switching speed of the frame image is controlled according to the number of contact operations for each area of the touch panel 5a, and the first area A1 Corresponds to "fast forward" which switches the frame image in the forward direction at a high speed with respect to the normal switching speed, and the second region A2 corresponds to "fast rewind" which switches the frame image in the reverse direction at a high speed with respect to the normal switching speed. It corresponds to.
Further, for example, when the touch panel 5a is divided into four regions of the first to fourth regions A1 to A4 (see FIG. 2B), the first region A1 and the third region A3 are in order as the switching direction. The directions are associated with each other, and the second region A2 and the fourth region A4 are associated with opposite directions as switching directions. Similarly to the above, in the switching display process by the first switching control unit 6c, the first region A1 corresponds to "fast forward" in which the frame image is switched in the forward direction at a high speed with respect to the normal switching speed, and the second The area A2 corresponds to "fast rewind" that switches the frame image in the opposite direction at a high speed with respect to the normal switching speed, and the third area A3 switches the frame image in the forward direction at a low speed with respect to the normal switching speed. Corresponding to "delayed forward", the fourth region A4 corresponds to "delayed rewind" in which the frame image is switched in the opposite direction at a low speed with respect to the normal switching speed.

In addition, in FIG. 2A and FIG. 2B, an example of a plurality of regions for dividing the touch panel 5a provided integrally with the display panel 4a is schematically shown, and is actually shown. The broken line indicating the boundary between the areas in each figure and the words "fast forward", "fast rewind", "slow forward", and "delay" are not displayed on the display panel 4a.

The operation processing unit 6 includes a contact number detection unit 6a, a first contact area detection unit 6b, and a first switching control unit 6c.
Each part of the operation processing unit 6 is composed of, for example, a predetermined logic circuit, but the configuration is an example and is not limited to this.

The contact number detecting unit (number detecting means) 6a detects the number of contact operations performed by the user in a series of simultaneous or continuous contact operations with respect to the touch panel 5a.
Here, a series of simultaneous or continuous contact operations by the user with respect to the touch panel 5a refers to connected and mutually related contact operations. That is, the number of contact operations performed at the same time and the number of contact operations with a time difference are not limited, and the number of contact operations performed at the same time may be one or more, and there is a time difference. The number of contact operations may be one or a plurality of times. That is, for example, a contact operation in which the user touches a plurality of contact positions with respect to the touch panel 5a at the same time, or a contact position of any one of the plurality of contact positions of the touch panel 5a by the user (for example, in the first region A1). While maintaining the contact state at the included contact position, etc.), perform a contact operation or the like to temporarily release the contact state at another contact position (for example, the contact position included in the second region A2) and then return to the contact state. Including.
In the contact operation performed on the touch panel 5a at the same time, if it is possible to secure a state in which the touch panel 5a is in contact with a plurality of contact positions at the same time, the contact operation by the user to each contact position is performed with a time lag. Includes contact operations. That is, even if the user touches each of the plurality of contact positions of the touch panel 5a with a time lag, the user is in contact with the touch panel 5a at the same time at the plurality of contact positions. It suffices if it is secured.

Then, each time the touch panel 5a is touched by a series of simultaneous or continuous touch operations by the user with respect to the touch panel 5a, the contact number detection unit 6a outputs a position signal related to the XY coordinates of the contact position output from the touch panel 5a. Acquire and detect the number of contact operations based on the acquired position signal. Specifically, for example, when the contact number detection unit 6a acquires a position signal related to one XY coordinate of the touch panel 5a, the contact operation is performed by the user at one location of the touch panel 5a. Detects that the number of is 1. Further, when the contact number detection unit 6a acquires position signals related to a plurality of (for example, two) different XY coordinates of the touch panel 5a, for example, a plurality of locations (for example, two locations) of the touch panel 5a differ depending on the user. Is a state in which a contact operation is performed, and it is detected that the number of contact operations is a plurality (for example, 2).
Here, the detection of the number of contact operations by the contact number detection unit 6a is, for example, a period during which the position signal is continuously acquired based on the continuous contact operation of the touch panel 5a by the user, or the beginning of the touch panel 5a by the user. It is performed until a predetermined time elapses after the position signal is acquired based on the contact operation of.

The first contact area detecting unit (area detecting means) 6b detects an area including a contact position contacted by a series of simultaneous or continuous contact operations by the user among a plurality of areas for dividing the touch panel 5a. ..
That is, when the touch panel 5a is contacted by the user in a series of simultaneous or continuous contact operations with the touch panel 5a, the first contact area detection unit 6b is a position signal related to the XY coordinates of the contact position output from the touch panel 5a. Is acquired, and the region including the acquired position signal is detected among the plurality of regions that divide the touch panel 5a. Specifically, when the first contact area detection unit 6b acquires, for example, a position signal related to one XY coordinate of the touch panel 5a, the first contact area detection unit 6b includes one area (for example, the first region) including the acquired position signal. Region A1 etc.) is detected. Further, when the first contact area detection unit 6b acquires, for example, a plurality of (for example, two) position signals related to different XY coordinates of the touch panel 5a, a plurality of acquired position signals are included. Regions (eg, first region A1 and second region A2, etc.) are detected.
Here, the detection of the contact area by the first contact area detection unit 6b is, for example, a period during which the position signal is continuously acquired based on the continuous contact operation of the touch panel 5a by the user, or the beginning of the touch panel 5a by the user. It is performed until a predetermined time elapses after the position signal is acquired based on the contact operation of.

The first switching control unit 6c controls the reproduction of the moving image displayed on the display unit 4, that is, the switching display of a plurality of frame images constituting the moving image.
That is, the operation processing unit 6 includes, for example, a VRAM (Video Random Access Memory), a VRAM controller, a digital video encoder, and the like (all of which are not shown). Then, the digital video encoder transmits the luminance signal Y and the color difference signals Cb and Cr decoded by the image processing unit (not shown) and recorded in the VRAM from the VRAM via the VRAM controller at a predetermined reproduction frame rate (for example, for example). It is read out at 30 fps), a video signal is generated based on these data, and the video signal is output to the display panel 4a of the display unit 4.
At this time, the first reproduction control unit (control means) 6c is based on the number of contact operations detected by the contact number detection unit 6a and the area of the touch panel 5a detected by the first contact area detection unit 6b. Controls the switching display for switching the frame image displayed on the display panel 4a to another frame image (switching display processing). For example, in the first switching control unit 6c, when one region (for example, the first region A1 or the like) is detected by the first contact region detection unit 6b, the number of contact operations detected by the contact number detection unit 6a. In accordance with the above, control is performed to adjust the switching speed when switching a plurality of frame images constituting the moving image in the switching direction (for example, progressive feed or the like) associated with one area.

For example, as shown in FIG. 3A, when the touch panel 5a is divided into two areas, a first area A1 and a second area A2, the user's contact area is the "first area A1" and the number of contacts. However, when the number of contacts is "1", the frame image is switched forward at 1x speed, and the frame image is switched forward at 2x speed. When the number of contacts is "2", the frame image is switched forward at 2x speed. When the number of contacts is "3", the frame image is switched in the forward direction at 3x speed, which is "3x speed forward reproduction". Further, when the user's contact area is "first area A2" and the number of contacts is "1", the frame image is switched in the reverse direction at 1x speed, and "1x speed reverse playback" is performed. When the number of contacts is "3", the frame image is switched in the reverse direction at 3x speed, and the frame image is switched in the reverse direction.
Further, for example, as shown in FIG. 3B, when the touch panel 5a is divided into four regions of the first to fourth regions A1 to A4, the user's contact region is "first region A1" and "1st region A1". In the second region A2, the same processing as in FIG. 3A described above is performed. Further, when the user's contact area is "third area A3" and the number of contacts is "1", the frame image is switched in the forward direction at 1x speed, which is "1x speed forward playback", and when the number of contacts is "2", 1 /. "1/2x speed forward playback" that switches the frame image in the forward direction at 2x speed, and "1/3x speed forward playback" that switches the frame image in the forward direction at 1/3x speed when the number of contacts is "3". Become. Further, when the user's contact area is "4th area A4" and the number of contacts is "1", the frame image is switched in the reverse direction at 1x speed, which is "1x speed reverse playback", and when the number of contacts is "2", 1 /. "1/2x speed reverse playback" that switches the frame image in the reverse direction at 2x speed, and "1/3x reverse direction playback" that switches the frame image in the reverse direction at 1/3x speed when the number of contacts is "3". Become.

The adjustment of the switching speed described above may be performed only during the period in which the touch panel 5a is touch-operated by the user, and may be returned to forward playback at 1x speed after the contact operation is released. However, even after the contact operation is released, the image switching speed adjusted according to the number of contact operations may be maintained, and the user can appropriately select the image switching speed.
Further, as a specific adjustment method of the switching speed, for example, setting of a reproduction frame rate and a thinning rate, etc. can be mentioned, but setting of a reproduction frame rate and a thinning rate is a known technique, and detailed description thereof will be given. Omit.

Further, for example, when a plurality of regions (for example, the first region A1 and the second region A2) are detected by the first contact region detection unit 6b, the first switching control unit 6c constitutes a plurality of moving images. The switching display is controlled by the control contents other than the adjustment of the switching speed of the frame image of.
Here, the control contents other than the adjustment of the switching speed of the frame image include pausing while displaying the frame image displayed on the display panel 4a when the user touches the touch panel 5a. For example, switching to a predetermined image such as the first frame image constituting the moving image, the last frame image, the first frame image of each chapter, and the like can be mentioned.
The chapters for the moving image may be set automatically by a known technique when shooting or recording the moving image, or may be manually set by the user.

Specifically, as a series of contact operations by the user to the touch panel 5a, for example, a plurality of regions (for example, the first region A1 and the second region A2) are simultaneously touched, so that the first contact region detection unit When a plurality of regions are detected by 6b, the first switching control unit 6c pauses while displaying the frame image displayed on the display panel 4a. In this case, the contact state at any of the plurality of contact positions included in the plurality of regions (for example, the contact position included in the first region A1) is maintained by the user, and the other contact is maintained. When a contact operation is performed to temporarily release the contact state at the position (for example, the contact position included in the second region A2) and then return to the contact state, the first switching control unit 6c displays one or a plurality of frame images. Switching to a predetermined image is performed by feeding an image sent in a predetermined direction (for example, forward or reverse direction).
For example, as shown in FIG. 3A, when the touch panel 5a is divided into two regions, a first region A1 and a second region A2, the first region A1 and the second region A2 are simultaneously contacted by the user. When this is done (the contact area is "first area A1 + second area A2" and the number of contacts is "2"), the frame image displayed on the display panel 4a is "paused" while being displayed. In this case, in the "first area A1", the area where the contact operation is performed to temporarily release the contact state and then return to the contact state (the area where the contact is re-contacted after the contact is released) is switched in the forward direction by one frame image "in order". In the "second area A2", the area to be re-contacted after the contact is released is the "reverse frame advance" in which the image is switched in the opposite direction by one frame image.
Further, for example, as shown in FIG. 3B, when the touch panel 5a is divided into four regions of the first to fourth regions A1 to A4, the contact operation with respect to the first region A1 and the second region A2 may be performed. , The process is the same as that of FIG. 3 (a) described above. Further, when the first region A1 and the third region A3 are contacted at the same time by the user (the contact region is "first region A1 + third region A3" and the number of contacts is "2"), it is displayed on the display panel 4a. It is a "jump to the end" that switches the frame image that is being displayed to the last frame image. Further, when the first region A1 and the fourth region A4 are simultaneously contacted by the user (the contact region is "first region A1 + fourth region A4" and the number of contacts is "2"), the image is displayed on the display panel 4a. It becomes a "pause" with the frame image displayed, and the subsequent processing switches to the first frame image of the next chapter in the forward direction when the area to be re-contacted is "first area A1" after the contact is released. In the "fourth region A4", the region to be re-contacted after the contact is released is the "forward chapter feed", and the region is switched to the first frame image of the next chapter in the reverse direction. Further, when the second region A2 and the third region A3 are simultaneously contacted by the user (the contact region is "second region A2 + third region A3" and the number of contacts is "2"), the display panel 4a is displayed. The frame image is "paused" while being displayed, and the subsequent processing is "reverse chapter feed" in the "second area A2" where the re-contact area is after the contact is released, and the contact is released and then re-contacted. When the contact area is the "third area A3", the contact area is "forward chapter feed". Further, when the second region A2 and the fourth region A4 are contacted at the same time by the user (the contact region is "second region A2 + fourth region A4" and the number of contacts is "2"), the display panel 4a is displayed. It is a "jump to the beginning" that switches the frame image that is being displayed to the first frame image. Further, when the third region A3 and the fourth region A4 are simultaneously contacted by the user (the contact region is "third region A3 + fourth region A4" and the number of contacts is "2"), the display panel 4a is displayed. The frame image is "paused" while being displayed, and the subsequent processing is "forward frame advance" in the "third area A3" where the area to be re-contacted is "forward frame advance" after the contact is released, and then re-contacted. When the contact area is the "fourth area A4", it is "reverse frame advance".

The switching display processing shown in FIGS. 3A and 3B is an example, and the switching speed, switching direction, processing content, and the like of the frame image can be arbitrarily changed as appropriate. For example, when adjusting the image switching speed, the weight may be changed by setting the number of contacts as a multiplier. Further, when the touch panel 5a is divided into three or more regions, the number of contacts operated at the same time may be three or more.

<Reproduction processing>
Next, the reproduction process by the display device 100 will be described with reference to FIG.
FIG. 4 is a flowchart showing an example of the operation related to the reproduction process.
In the following reproduction processing, it is assumed that the touch panel 5a is divided into two regions, a first region A1 and a second region A2. Further, the adjustment of the switching speed of the frame image shall be performed only during the period in which the touch panel 5a is touch-operated by the user.

As shown in FIG. 4, first, among the moving images recorded in the image recording unit 3, when the moving image to be displayed is specified based on a predetermined operation of the operation input unit 5 by the user, the operation processing unit 6 reads a designated moving image from the image recording unit 3, outputs a plurality of frame images constituting the moving image decoded by an image processing unit (not shown) to the display unit 4, and the first switching control unit 6c , The moving image displayed on the display panel 4a is reproduced at a predetermined reproduction frame rate (for example, 30 fps or the like) (step S1).

Next, the operation processing unit 6 determines whether or not the touch panel 5a has been touch-operated by the user (step S2).
Here, if it is determined that the touch panel 5a has not been touch-operated (step S2; NO), the operation processing unit 6 determines whether or not the reproduction of the moving image is completed (step S3).

If it is determined in step S3 that the reproduction of the moving image has not been completed (step S3; NO), the operation processing unit 6 returns the processing to step S2 and determines whether or not the touch panel 5a has been touch-operated. The process to be performed is repeatedly executed at predetermined time intervals.
On the other hand, when it is determined in step S3 that the reproduction of the moving image is completed (step S3; YES), the operation processing unit 6 ends the reproduction processing.

When it is determined in step S2 that the touch panel 5a has been touched (step S2; YES), the contact number detection unit 6a acquires and acquires the position signal related to the XY coordinates of the contact position output from the touch panel 5a. The number of contact operations is detected based on the position signal (step S4). Subsequently, the first contact area detection unit 6b acquires the position signal related to the XY coordinates of the contact position output from the touch panel 5a, and includes the acquired position signal in the plurality of areas for dividing the touch panel 5a. (Step S5).
The order of detecting the number of contact operations in step S4 and detecting the contacted region in step S5 is an example and is not limited to this, and may be reversed, for example.

Next, the first switching control unit 6c determines whether or not a plurality of regions (for example, the first region A1 and the second region A2) have been detected by the first contact region detection unit 6b (step S6).
Here, if it is determined that a plurality of regions have not been detected (step S6; NO), the first switching control unit 6c determines the number of contact operations (for example, 2) detected by the contact number detection unit 6a. Correspondingly, the switching speed (for example, double speed) when switching a plurality of frame images constituting the moving image is adjusted (step S7). Subsequently, the first switching control unit 6c has a switching direction (for example, the first region A1) associated with one region (for example, the first region A1) detected by the first contact region detection unit 6b at the adjusted switching speed. , Sequential feed, etc.) to reproduce the moving image by the switching display (for example, double speed forward reproduction) that switches a plurality of frame images (step S8).

Next, the operation processing unit 6 determines whether or not the touch operation of the touch panel 5a by the user is completed (step S9).
Here, if it is determined that the touch operation of the touch panel 5a by the user has not been completed (step S9; NO), the first switching control unit 6c returns the process to step S8 and executes each subsequent process. .. That is, as described above, the processes of steps S8 and S9 are sequentially executed, and a plurality of frame images are switched and displayed according to the contact operation of the touch panel 5a by the user.

When it is determined in step S9 that the touch operation of the touch panel 5a by the user is completed (step S9; YES), the first switching control unit 6c changes the switching speed of the plurality of frame images to a normal switching speed (for example,). Return to 1x) and reproduce the moving image (step S10).
After that, the operation processing unit 6 returns the processing to step S2.

On the other hand, if it is determined in step S6 that a plurality of regions have been detected (step S6; YES), the first switching control unit 6c pauses while displaying the frame image displayed on the display panel 4a. (Step S11).
Subsequently, the operation processing unit 6 determines whether or not a contact operation has been performed at any one of the contact positions operated by the user to temporarily release the contact state and then return to the contact state (). Step S12).
Here, when it is determined that the contact operation of temporarily releasing the contact state and then returning to the contact state has not been performed (step S12; NO), the operation processing unit 6 ends the contact operation of the touch panel 5a by the user. It is determined whether or not this has been done (step S13).
Here, when it is determined that the touch operation of the touch panel 5a by the user has not been completed (step S13; NO), the first switching control unit 6c returns the process to step S11 and displays it on the display panel 4a. Keep the frame image paused.

When it is determined in step S12 that the contact operation of temporarily releasing the contact state and then returning to the contact state has been performed (step S12; YES), the first switching control unit 6c temporarily releases the contact state. By image advance (for example, forward frame advance) that switches one frame image in a predetermined direction (for example, forward direction) according to the area (for example, the first area A1) where the contact operation is performed to return to the contact state from Switching to an image is performed (step S14).

After that, the operation processing unit 6 shifts the processing to step S13, and determines whether or not the touch operation of the touch panel 5a by the user is completed (step S13).
Here, if it is determined that the touch operation of the touch panel 5a by the user has not been completed (step S13; NO), the first switching control unit 6c returns the process to step S11 and executes each subsequent process. .. That is, as described above, the processes of steps S11 to S14 are sequentially executed, and a plurality of frame images are switched and displayed according to the contact operation of the touch panel 5a by the user.

When it is determined in step S13 that the touch operation of the touch panel 5a by the user is completed (step S13; YES), the first switching control unit 6c shifts the process to step S10, and the switching speed of a plurality of frame images. Is returned to the normal switching speed (for example, 1 time), and the moving image is reproduced (step S10).

As described above, according to the display device 100 of the first embodiment, the number of contact operations performed by the user in a series of simultaneous or continuous contact operations with respect to the touch panel 5a and within a plurality of regions for dividing the touch panel 5a. Since the switching display for switching the frame image displayed on the display panel 4a to another frame image is controlled based on the area including the contact position contacted by the user in a series of simultaneous or continuous contact operations. , The types of selectable frame image switching display can be increased according to the number of contact operations and the combination of areas performed by the user in a series of simultaneous or continuous contact operations, and the touch panel 5a that can be mounted can be mounted. Even in a situation where the size of the image is limited, it is possible to suppress a decrease in operability when the user selects a desired switching display.

Further, when a plurality of regions for dividing the touch panel 5a are associated with different switching directions in the switching display and one region of the touch panel 5a is touched by a series of contact operations by the user, the contact operation is performed. Since control is performed to adjust the switching speed when switching the frame image in the switching direction associated with one area according to the number, the number of contact operations performed by the user in a series of contact operations with respect to the touch panel 5a and the number of contact operations are performed. The switching direction and switching speed can be changed depending on the contact position, and the user can select the desired switching display with a simpler operation.
Further, when a plurality of areas of the touch panel 5a are touch-operated by a series of contact operations by the user, the switching display is controlled by a control content other than the adjustment of the switching speed of the frame image. Depending on the mode of the contact operation performed by the contact operation, for example, it is possible to pause or switch to a predetermined image while displaying the frame image displayed on the display panel 4a, and the user can perform the desired switching. The display selection can be realized by a simpler operation. Specifically, a plurality of areas of the touch panel 5a are touch-operated by the user, and a plurality of areas included in the plurality of areas of the touch panel 5a are included in a state in which the frame image displayed on the display panel 4a is displayed and paused. One or more image feeds based on the contact operation of temporarily releasing the contact state at the other contact position and then returning to the contact state while maintaining the contact state at one of the contact positions of By switching to a predetermined image, a wider variety of switching displays can be realized by simple operations such as releasing the contact state and recontacting.
Further, in the series of contact operations by the user to the touch panel 5a, if it is possible to secure a state in which the touch panel 5a is in contact with a plurality of contact positions at the same time, the contact operations to the contact positions are performed with a time lag. Since the operation may be performed, it is not necessary that the timings of the contact operations at the plurality of contact positions of the touch panel 5a are exactly the same, and the user can realize the desired switching display selection with a simpler operation.

Further, when a plurality of contact operations are performed with a time lag in a series of contact operations by the user to the touch panel 5a, the second contact area detection unit 206b specifically determines the touch panel 5a by the user. When a plurality of contact operations are continuously performed within a time (for example, 500 ms), the order of the contact operations of the plurality of regions where the plurality of contact operations are performed is detected.
Here, the series of contact operations by the user with respect to the touch panel 5a is, for example, a contact operation in which the user touches a plurality of contact positions with respect to the touch panel 5a at the same time, as illustrated in the first embodiment, and the touch panel 5a by the user.

The subsequent contact operation may be performed while maintaining the contact state of the operation.

That is, each time the user performs a contact operation on the touch panel 5a, the second contact area detection unit 206b acquires a position signal related to the XY coordinates of the contact position output from the touch panel 5a, and the touch panel 5a is touch-operated. The time is obtained from the timekeeping section (not shown). Then, the second contact area detection unit 206b detects the area including the acquired position signal among the plurality of areas for dividing the touch panel 5a for each of the user's contact operations with respect to the touch panel 5a. Further, the second contact area detection unit 206b refers to the contact operation performed continuously within a predetermined time from the time when one contact operation with respect to any region of the touch panel 5a is performed, in a plurality of regions of the touch panel 5a.

The second switching control unit 206c controls the switching display of a plurality of frame images constituting the moving image, similarly to the first switching control unit 6c. Further, the second switching control unit 206c switches based on the order of a plurality of contact operations performed with a time lag in a series of contact operations by the user with respect to the touch panel 5a detected by the second contact area detection unit 206b. Control the display. Specifically, the second switching control unit 206c adjusts the switching speed of the plurality of frame images constituting the moving image based on the order of the plurality of contact operations detected by the second contact area detection unit 206b. The switching display is controlled by the control contents other than the adjustment of the switching speed.

(Simultaneous), it becomes "pause", and when the user continuously contacts the first region A1 and the second region A2 (the number of contacts is "2", the mode of contact is "2". "Continuous (first area comes first)"), "forward frame advance", and when the user continuously contacts the first area A1 following the second area A2 (the number of contacts is "2", The mode of contact is "continuous (second region comes first)") and "reverse frame advance". Further, when the user's contact areas are the "first area A1" and the "third area A3" and the two contact operations by the user are performed simultaneously or continuously (the contact modes are "simultaneous and continuous"). ), The number of contacts is "2"), and "jump to the end". Further, when the user's contact areas are the "first area A1" and the "fourth area A4" and the first area A1 and the fourth area A4 are contacted at the same time (the number of contacts is "2", the contact is performed. (Simultaneous), it becomes "pause", and when the user continuously contacts the first region A1 and the fourth region A4 (the number of contacts is "2", the mode of contact is "2".

As the switching display process, those shown in FIGS. 6 (a) and 6 (b) are examples, and the frame image is switched in the same manner as those shown in FIGS. 3 (a) and 3 (b). The speed, switching direction, processing content, etc. can be changed as appropriate.

Here, the timing for starting the control of the switching display by the second switching control unit 206c will be described.
As described above, does the second contact area detection unit 206b continuously perform the next contact operation from the time when one contact operation with respect to any region of the touch panel 5a is performed until a predetermined time elapses? It is designed to monitor whether or not it is. In other words, one contact operation is performed to determine whether the next contact operation is performed with a time lag after one contact operation or only one contact operation (regardless of the number of contact operations themselves). It is necessary to elapse a predetermined time from the time when it is broken.
Therefore, the second switching control unit 206c usually starts the control of the switching display after a predetermined time has elapsed from the time when the one contact operation is performed. For example, the one contact operation is performed. If the next contact operation is performed within a predetermined time from the time when it is performed (when it is found that the contact operation is continuous with a time lag), the predetermined time is from the time when one contact operation is performed. The control of the switching display may be started at a time before the elapse (for example, when the next contact operation is performed).

<Reproduction processing>
Next, the reproduction process by the display device 200 will be described with reference to FIGS. 7 and 8.
7 and 8 are flowcharts showing an example of the operation related to the reproduction process.
In the following reproduction processing, it is assumed that the touch panel 5a is divided into two regions, a first region A1 and a second region A2. Further, the adjustment of the switching speed of the frame image shall be performed only during the period in which the touch panel 5a is touch-operated by the user.

As shown in FIG. 7, first, among the moving images recorded in the image recording unit 3, when the moving image to be displayed is designated based on a predetermined operation of the operation input unit 5 by the user, the operation processing unit The 206 outputs a plurality of frame images constituting the designated moving image to the display unit 4, and the second switching control unit 206c is displayed on the display panel 4a, substantially similar to the reproduction process of the first embodiment. The moving image is reproduced at a predetermined reproduction frame rate (for example, 30 fps or the like) (step S21).

Next, the motion processing unit 206 determines whether or not the touch panel 5a has been touched (first touched) by the user (step S22).
Here, if it is determined that the touch panel 5a has not been touch-operated (step S22; NO), the operation processing unit 206 determines whether or not the reproduction of the moving image is completed (step S23).

If it is determined in step S23 that the reproduction of the moving image has not been completed (step S23; NO), the operation processing unit 206 returns the processing to step S22 and determines whether or not the touch panel 5a has been touch-operated. The process to be performed is repeatedly executed at predetermined time intervals.
On the other hand, when it is determined in step S23 that the reproduction of the moving image is completed (step S23; YES), the operation processing unit 206 ends the reproduction processing.

When it is determined in step S22 that the touch panel 5a has been touch-operated (step S22; YES), the contact number detection unit 6a has the contact position output from the touch panel 5a in substantially the same manner as in the reproduction process of the first embodiment. The position signal related to the XY coordinates of is acquired, and the number of contact operations is detected based on the acquired position signal (step S24). Subsequently, the second contact area detection unit 206b acquires the position signal related to the XY coordinates of the contact position output from the touch panel 5a, and includes the acquired position signal in the plurality of areas for dividing the touch panel 5a. The time when the touch panel 5a is touched is acquired from the time measuring unit (not shown) (step S25).

Next, the operation processing unit 206 determines whether or not the touch panel 5a has been touched (second and subsequent contact operations) by the user (step S26).
Here, if it is determined that the touch panel 5a has not been touch-operated (step S26; NO), the operation processing unit 206 determines whether or not a predetermined time has elapsed from the time when the first touch operation of the touch panel 5a is performed. (Step S27).

If it is determined in step S27 that a predetermined time has not elapsed since the first touch operation of the touch panel 5a was performed (step S27; NO), the operation processing unit 206 returns the process to step S26. , In the same manner as described above, it is determined whether or not the touch panel 5a has been subjected to a contact operation (second and subsequent contact operations) (step S26).

When it is determined in step S26 that the touch panel 5a has been touch-operated (step S26; YES), the contact number detection unit 6a is located at the position related to the XY coordinates of the contact position output from the touch panel 5a, as in step S24. A signal is acquired and the number of contact operations is detected based on the acquired position signal (step S28). Subsequently, the second contact area detection unit 206b acquires the position signal related to the XY coordinates of the contact position output from the touch panel 5a in the same manner as in step S25, and acquires the position signal in the plurality of areas for dividing the touch panel 5a. The region including the coordinated position signal is detected, and the time when the touch panel 5a is touch-operated is acquired from the time measuring unit (not shown) (step S29).
Then, the operation processing unit 206 returns to step S26 and repeats the determination of whether or not the touch panel 5a has been subjected to a contact operation (second and subsequent contact operations).

After that, when it is determined in step S27 that a predetermined time has elapsed from the time when the first touch operation of the touch panel 5a is performed (step S27; YES), as shown in FIG. 8, the second switching control unit The 206c determines whether or not a plurality of regions (for example, the first region A1 and the second region A2) have been detected by the second contact region detection unit 206b (step S30).

If it is determined in step S30 that a plurality of regions have not been detected (step S30; NO), the second switching control unit 206c determines the number of contact operations detected by the contact number detection unit 6a (for example, 2). ), The switching speed (for example, double speed) when switching a plurality of frame images constituting the moving image is adjusted (step S31). Subsequently, the second switching control unit 206c has a switching direction (for example, the first region A1) associated with one region (for example, the first region A1) detected by the second contact region detection unit 206b at the adjusted switching speed. , Sequential feed, etc.) to reproduce the moving image by the switching display (for example, double speed forward reproduction) that switches a plurality of frame images (step S32).

Next, the operation processing unit 206 determines whether or not the touch operation of the touch panel 5a by the user is completed (step S33).
Here, if it is determined that the touch panel 5a contact operation by the user has not been completed (step S33; NO), the second switching control unit 206c returns the process to step S32, and the user touches the touch panel 5a. It continuously controls the switching display of a plurality of frame images according to the situation.

When it is determined in step S33 that the touch operation of the touch panel 5a by the user is completed (step S33; YES), the second switching control unit 206c sets the switching speed of the plurality of frame images to a normal switching speed (for example,). (1x) is returned to, and the moving image is reproduced (step S34).
After that, the operation processing unit 206 returns the processing to step S22.

On the other hand, if it is determined in step S30 that a plurality of regions have been detected (step S30; YES), the second switching control unit 206c has a plurality of regions detected by the second contact region detection unit 206b by the user. At the same time, it is determined whether or not the contact operation has been performed (step S35).
Here, when it is determined that the plurality of areas are simultaneously touch-operated by the user (step S35; YES), the second switching control unit 206c pauses while displaying the frame image displayed on the display panel 4a. (Step S36).

Subsequently, the operation processing unit 206 determines whether or not the touch operation of the touch panel 5a by the user is completed (step S37).
Here, when it is determined that the touch operation of the touch panel 5a by the user has not been completed (step S37; NO), the second switching control unit 206c returns the process to step S36 and displays it on the display panel 4a. Keep the frame image paused.

When it is determined in step S37 that the touch operation of the touch panel 5a by the user is completed (step S37; YES), the second switching control unit 206c shifts the process to step S34, and the switching speed of a plurality of frame images. Is returned to the normal switching speed (for example, 1 time), and the moving image is reproduced (step S34).
After that, the operation processing unit 206 returns the processing to step S22.

On the other hand, if it is determined in step S35 that the plurality of regions are not touch-operated at the same time by the user (step S35; NO), the second switching control unit 206c is in the order in which the plurality of regions are touch-operated (for example,). , The first region A1 is first), and a switching display (for example, 1/2 times speed) for switching a plurality of frame images in a switching direction (for example, forward direction) according to the specified order (for example, 1/2 times speed). For example, the moving image is reproduced by (1 / 2x speed forward reproduction) (step S38).

After that, the operation processing unit 206 determines whether or not the touch operation of the touch panel 5a by the user is completed (step S39).
Here, when it is determined that the touch operation of the touch panel 5a by the user has not been completed (step S39; NO), the second switching control unit 206c returns the process to step S38, and the contact operation is performed on a plurality of regions. The switching display for switching a plurality of frame images at a predetermined switching speed in the switching direction according to the order is continuously controlled.

When it is determined in step S39 that the touch operation of the touch panel 5a by the user is completed (step S39; YES), the second switching control unit 206c shifts the process to step S34, and the switching speed of a plurality of frame images. Is returned to the normal switching speed (for example, 1 time), and the moving image is reproduced (step S34).
After that, the operation processing unit 206 returns the processing to step S22.

As described above, according to the display device 200 of the second embodiment, similarly to the first embodiment, the number of contact operations and the combination of regions performed by the user in a series of simultaneous or continuous contact operations are supported. , The types of selectable frame image switching display can be increased, and even in a situation where the size of the mountable touch panel 5a is limited, the operability when the user selects the desired switching display is reduced. It can be suppressed. In particular, in a series of contact operations by the user with respect to the touch panel 5a, for example, when a plurality of contact operations are continuously performed with respect to the touch panel 5a within a predetermined time, a plurality of contact operations are performed with a time lag. In addition, since the switching display is controlled based on the order of the contact operations of the plurality of areas where the plurality of contact operations are performed, the order of the plurality of contact operations performed by the user in the series of contact operations with respect to the touch panel 5a can be changed. By simply changing, the switching direction and switching speed can be changed, the frame image can be paused while being displayed, and the image can be switched to a predetermined image, making it easier for the user to select the desired switching display. It can be realized by operation.

The present invention is not limited to the first and second embodiments, and various improvements and design changes may be made without departing from the spirit of the present invention.
Hereinafter, the display device 300 of the first modification will be described with reference to FIG.
The points other than those described below have substantially the same configurations and functions as those of the display devices 100 and 200 of the first and second embodiments, and the specific description thereof will be omitted.

<Modification example 1>
FIG. 9 is a diagram schematically showing an example of guidance display by the display device 300 of the modified example 1.
The display device 300 of the modification 1 guides and displays a frame image switching method on the display panel 4a (see FIG. 9).

That is, the first switching control unit 6c (or the second switching control unit 206c) displays the frame image displayed on the display panel 4a when the number of contact operations detected by the contact number detection unit 6a is one. The display panel 4a guides and displays the method of switching the frame image in the switching display for switching to another frame image.
Specifically, for example, when the user performs one contact operation on any one position of the touch panel 5a, the first switching control unit 6c is associated with a plurality of regions for dividing the touch panel 5a. The guidance display G indicating the switching direction, switching speed, etc. is superimposed on the frame image and displayed on the display panel 4a. Further, the first switching control unit 6c superimposes the guidance display G on the frame image and displays it on the display panel 4a, for example, during the period during which the touch panel 5a is continuously touched by the user.
At this time, in order to prevent an erroneous operation in which the touch panel 5a is touched by the user for a moment, the first switching control unit 6c measures, for example, the time during which one contact operation with the touch panel 5a by the user continues. Then, when the measured time becomes a predetermined time (for example, 200 ms) or more, the guidance display G may be displayed on the display panel 4a.

Therefore, according to the display device 300 of the first modification, when the number of contact operations performed by the user in a series of contact operations with respect to the touch panel 5a is one, the display panel 4a guides the method of switching the frame image in the switching display. Since the display is displayed, the user can perform various contact operations of the touch panel 5a using the guidance display G displayed on the display panel 4a, and improve the operability when the user selects the desired switching display. Can be done.

The first switching control unit 6c may change the content of the guidance display G and the control content of the switching display according to the area where the touch panel 5a is touch-operated by the user. For example, as the control content of the switching display, the first area A1 of the touch panel 5a is associated with a forward switching display such as "double speed forward playback", and the second area A2 is associated with "double speed reverse direction". It is assumed that the switching display in the reverse direction such as "reproduction" is associated with the display. In this state, when the first area A1 of the touch panel 5a corresponding to the guidance display G related to "fast forward" is touch-operated, the first switching control unit 6c corresponds to the second area A2 of the display panel 4a. A guidance display (not shown) related to "pause" is displayed in place of the guidance display G related to "fast rewind", and the control content of the switching display corresponding to the second area A2 is displayed on the display panel 4a. "Pause" with the displayed frame image displayed.
