Hereinafter, preferred embodiments of a display control apparatus and a control method of the display control apparatus of the present invention will be described with reference to the drawings.
FIG. 1 shows an external view of a digital camera as an example of the imaging apparatus of the present invention.
The display unit 28 is a display unit that displays an image and various information. A shutter button 61 is an operation unit for giving a photographing instruction. The mode switching switch 60 is an operation unit for switching various modes.

  The connector 112 is a connector between the connection cable 111 and the digital camera 100. The operation unit 70 is an operation unit including operation members such as various switches, buttons, and a touch panel that receive various operations from the user. The controller wheel 73 is a rotatable operation member included in the operation unit 70.

  The power switch 72 is a push button for switching power on / off. The recording medium 200 is a recording medium such as a memory card or a hard disk. The recording medium slot 201 is a slot for storing the recording medium 200. The recording medium 200 stored in the recording medium slot 201 can communicate with the digital camera 100. The lid 202 is a lid of the recording medium slot 201.

FIG. 2 is a block diagram showing a configuration example of the digital camera 100 according to the present embodiment.
In FIG. 2, a photographing lens 103 is a lens group including a zoom lens and a focus lens. The shutter 101 is a shutter having an aperture function. The imaging unit 22 is an imaging device configured of a CCD, a CMOS device, or the like that converts an optical image into an electrical signal.

  The A / D converter 23 is used to convert an analog signal output from the imaging unit 22 into a digital signal. The barrier 102 covers the imaging system including the imaging lens 103 of the digital camera 100 to prevent the contamination and damage of the imaging system including the imaging lens 103, the shutter 101, and the imaging unit 22.

  The image processing unit 24 performs resizing processing such as predetermined pixel interpolation and reduction and color conversion processing on data from the A / D converter 23 or data from the memory control unit 15. Further, in the image processing unit 24, predetermined arithmetic processing is performed using captured image data, and the system control unit 50 performs exposure control and distance measurement control based on the obtained calculation result.

  As a result, TTL (through-the-lens) AF (auto focus) processing, AE (automatic exposure) processing, and EF (flash pre-emission) processing are performed. The image processing unit 24 further performs predetermined arithmetic processing using captured image data, and also performs TTL AWB (auto white balance) processing based on the obtained arithmetic result.

  Output data from the A / D converter 23 is directly written to the memory 32 through the image processing unit 24 and the memory control unit 15 or through the memory control unit 15. The memory 32 stores image data obtained by the imaging unit 22 and converted into digital data by the A / D converter 23, and image data to be displayed on the display unit 28. The memory 32 has a sufficient storage capacity to store a predetermined number of still images and moving images and sounds for a predetermined time.

  The memory 32 also serves as a memory (video memory) for displaying an image. The D / A converter 13 converts the image display data stored in the memory 32 into an analog signal and supplies the analog signal to the display unit 28. Thus, the display image data written in the memory 32 is displayed by the display unit 28 via the D / A converter 13.

  The display unit 28 performs display according to the analog signal from the D / A converter 13 on a display such as an LCD. As an electronic view finder, the digital signal that has been A / D converted once by A / D converter 23 and analog converted by D / A converter 13 in D / A converter 13 is sequentially transferred to display unit 28 for display. It functions and can perform through image display (live view display).

  The non-volatile memory 56 is an electrically erasable / recordable memory, and for example, an EEPROM or the like is used. In the non-volatile memory 56, constants, programs and the like for operation of the system control unit 50 are stored. The program referred to here is a program for executing various flowcharts to be described later in the present embodiment.

  The system control unit 50 controls the entire digital camera 100. By executing the program stored in the non-volatile memory 56 described above, each process of the present embodiment described later is realized. 52 is a system memory, and a RAM is used. In the system memory 52, constants and variables for the operation of the system control unit 50, programs read out from the non-volatile memory 56, etc. are expanded. The system control unit 50 also performs display control by controlling the memory 32, the D / A converter 13, the display unit 28, and the like. The system timer 53 is a clock unit that measures the time used for various controls and the time of the built-in clock.

  A mode change switch 60, a shutter button 61, and an operation unit 70 are operation means for inputting various operation instructions to the system control unit 50. The mode switching switch 60 switches the operation mode of the system control unit 50 to any one of a still image recording mode, a moving image recording mode, a reproduction mode, and the like. As modes included in the still image recording mode, there are an auto shooting mode, an auto scene determination mode, a manual mode, various scene modes as shooting settings for each shooting scene, a program AE mode, a custom mode and the like.

  The mode switching switch 60 directly switches to any of these modes included in the still image shooting mode. Alternatively, once the mode is switched to the still image shooting mode by the mode switching switch 60, another operation member may be used to switch to any of these modes included in the still image shooting mode. Similarly, a plurality of moving image shooting modes may be included.

  During the operation of the shutter button 61 provided to the digital camera 100, the first shutter switch 62 is turned on by a so-called half depression (shooting preparation instruction) and generates a first shutter switch signal SW1. The first shutter switch signal SW1 starts operations such as AF (auto focus) processing, AE (automatic exposure) processing, AWB (auto white balance) processing, and EF (flash pre-emission) processing.

  The second shutter switch 64 is turned on by completion of the operation of the shutter button 61, that is, full-press (shooting instruction), and generates a second shutter switch signal SW2. The system control unit 50 starts a series of photographing processing operations from reading of the signal from the imaging unit 22 to writing of image data on the recording medium 200 by the second shutter switch signal SW2.

  Each operation member of the operation unit 70 is appropriately assigned a function for each scene by selecting and operating various function icons displayed on the display unit 28, and functions as various function buttons. The function buttons include, for example, an end button, a back button, an image feed button, a jump button, a narrowing button, and an attribute change button. For example, when the menu button is pressed, various settable menu screens are displayed on the display unit 28. The user can intuitively perform various settings using the menu screen displayed on the display unit 28 and the four-direction button or the SET button on the top, bottom, left, and right.

  The controller wheel 73 is a rotatable operation member included in the operation unit 70, and is used together with the direction button to designate a selection item. When the controller wheel 73 is rotated, an electrical pulse signal is generated according to the amount of operation, and the system control unit 50 controls each part of the digital camera 100 based on the pulse signal. Based on this pulse signal, it is possible to determine the angle at which the controller wheel 73 is operated to rotate, how many rotations, and the like.

  The controller wheel 73 may be any operation member as long as it can detect a rotation operation. For example, the controller wheel 73 may be a dial operation member that rotates to generate a pulse signal according to a user's rotation operation. Alternatively, the operation member may be a touch sensor, and the controller wheel 73 itself may not rotate, and may detect a user's finger rotation operation on the controller wheel 73 (so-called touch wheel).

  The power supply control unit 80 includes a battery detection circuit, a DC-DC converter, a switch circuit for switching a block to be energized, and the like, and detects the presence or absence of a battery, the type of battery, and the battery remaining amount. Further, the power control unit 80 controls the DC-DC converter based on the detection result and an instruction of the system control unit 50, and supplies necessary voltages to the respective units including the recording medium 200 for a necessary period.

  The power supply unit 30 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, or the like. The recording medium I / F 18 is an interface with the recording medium 200 such as a memory card or a hard disk. The recording medium 200 is a recording medium such as a memory card for recording a photographed image, and is formed of a semiconductor memory, a magnetic disk, or the like.

  The communication unit 54 is connected by wireless or a priority cable to transmit and receive video signals and audio signals. The communication unit 54 can also connect to a wireless LAN (Local Area Network) or the Internet. The communication unit 54 can transmit an image (including a through image) captured by the imaging unit 22 and an image recorded on the recording medium 200, and can receive image data and other various information from an external device. it can.

  The posture detection unit 55 detects the posture of the digital camera 100 with respect to the gravity direction. Based on the posture detected by the posture detection unit 55, whether the image photographed by the imaging unit 22 is an image photographed by holding the digital camera 100 horizontally or an image photographed by holding the digital camera 100 vertically It can be determined. The system control unit 50 can add orientation information according to the posture detected by the posture detection unit 55 to the image file of the image captured by the imaging unit 22, or can rotate and record the image. is there. As the posture detection unit 55, an acceleration sensor, a gyro sensor, or the like can be used.

  A touch panel capable of detecting a touch on the display unit 28 is provided as one of the operation units 70. The touch panel and the display unit 28 can be integrally configured. For example, the touch panel is configured such that the light transmittance does not interfere with the display of the display unit 28, and the touch panel is attached to the upper layer of the display surface of the display unit 28. Then, the input coordinates on the touch panel are associated with the display coordinates on the display unit 28. As a result, it is possible to configure a GUI (Graphical User Interface) as if the user can directly operate the screen displayed on the display unit 28.

The system control unit 50 can detect the following operation or state on the touch panel.
(A) Touching the touch panel with a finger or a pen (hereinafter referred to as touch-down).
(B) The touch panel is in a state of being touched with a finger or a pen (hereinafter referred to as touch-on).
(C) Moving the touch panel while touching it with a finger or a pen (hereinafter referred to as "Touch-Move").
(D) releasing the finger or pen touching the touch panel (hereinafter, referred to as touch-up).
(E) A state in which nothing is touched on the touch panel (hereinafter referred to as touch-off).

  The system control unit 50 is notified of the operations / states of these (i) to (e) and the position coordinates where a finger or pen is touching on the touch panel through the internal bus, and the system control unit 50 is based on the notified information. It is determined what operation has been performed on the touch panel. With regard to the touch move, the moving direction of the finger or pen moving on the touch panel can also be determined for each vertical component and horizontal component on the touch panel based on the change in position coordinates. Thus, a touch detection function of detecting a touch operation on the display unit 28 can be configured.

  In addition, it is assumed that a stroke is drawn when touch-up is performed on the touch panel from touch-down through constant touch move. The operation of drawing a stroke quickly is called a flick. The flick is an operation in which the touch panel is moved quickly by a certain distance while touching a finger on the touch panel and is released as it is, in other words, an operation in which the touch panel is quickly swiped with fingers.

  It is detected that touch move is performed at a predetermined speed or more at a predetermined distance or more, and when touch-up is detected as it is, it can be determined that flicking has been performed. Further, when it is detected that the touch move is performed at a predetermined distance or more at a speed less than the predetermined speed, it is determined that the dragging is performed. In addition, in a state in which two points are touched simultaneously (two or more points are simultaneously), an operation to narrow or widen the distance between the two points is called a pinch.

  Among them, an operation in which the distance between two points is narrowed is called pinch in. Pinch-in is an operation of bringing two fingers close together while touching the multi touch panel, in other words, an operation of pinching two fingers on the multi touch panel. Conversely, in the state in which two points are touched simultaneously, the operation of increasing the distance between the two points is called pinch out. Furthermore, a state in which the touch panel is not touched but a finger or a pen is brought close to the touch panel is called a hover.

  The touch panel may be any of various touch panels such as resistive film type, capacitive type, surface acoustic wave type, infrared type, electromagnetic induction type, image recognition type, optical sensor type, etc. .

  FIG. 3 is a view showing a display example in the case where the image 501 (for example, an image with the file name 0001.jpg) is displayed on the entire screen of the display unit 28 (display at the maximum size in which the entire image fits in the display area). . When the image of FIG. 3 is enlarged, the image is enlarged at the center reference, and the display state of FIG. 4 is obtained.

  FIG. 4 is a view showing a display example on the display unit 28 when the image 501 is enlarged and displayed. Not the whole image but a part is enlarged and displayed on the display unit 28. A guide 503 indicates a portion (white-painted portion) displayed in an enlarged manner in the entire image 501 (white frame). According to the guide 503, it can be seen in FIG. 4 that the central portion of the image 501 is enlarged. From this state, when the enlargement position is changed by the enlargement position instruction and the enlargement position is moved upward, the display state shown in FIG. 5A is obtained. Reference numeral 504 denotes a menu button displayed on the display unit 28.

  FIG. 5A is a schematic view in a case where two points are touched with a finger 505 and touch move is performed on both points when the enlarged position of the image 501 is displayed in the vicinity of the upper center. In the present embodiment, the enlarged image sending is performed by the touch move of two points, and the display state of FIG. 5A is switched to the display state of FIG. 5B.

  FIG. 5B is a display example in which the same enlargement position as that of FIG. 5A is enlarged for the image 502 (for example, the image with the file name 0002.jpg) whose image sending order is next to the image 501. . As seen from the guide 503, the ratio of the enlargement range to the enlargement position and the whole is before and after the enlargement feed (FIG. 5 (a) (first image) and FIG. 5 (b) (second image)). It can be seen that there is no change, and image feed with fixed magnification center position and magnification is performed.

Hereinafter, processing for realizing such a transition will be described using a flowchart.
6, 7 and 8 show flowcharts for explaining the operation of this embodiment. This processing is realized by expanding the program recorded in the non-volatile memory 56 in the system memory 52 and executing the program by the system control unit 50.

FIG. 6 is a flowchart showing the processing procedure of the single reproduction mode for reproducing one image.
First, in S601, the image number N of the newest image among the images recorded on the recording medium 200 is acquired.
At S602, the N-th image is read and arranged in the memory 32.
At S603, the image arranged in the memory 32 is decoded and displayed on the display unit 28 (FIG. 3).
In S604, it is determined whether or not there is an input to the operation unit 70. If there is an input, the process advances to step S605; otherwise, the process continues to wait until there is an input in step S604.

  In S605, it is determined whether the input operation is a magnifying operation. The enlargement operation includes, for example, an operation to the Tele side of the zoom lever (zoom operation member) included in the operation unit 70 (the same operation as the enlargement with the optical zoom at the time of photographing). In addition, it can be enlarged by pinch out operation on the touch panel. If it is the enlargement operation, the process proceeds to step S606. If not, the process proceeds to step S608.

In S606, the image displayed on the display unit 28 is enlarged and displayed, and the process proceeds to S607 (FIG. 4).
In step S608, it is determined whether the input operation is an image feed operation. The image forwarding operation includes an operation in the forward direction and an operation in the reverse direction. In the forward direction, the image following the currently displayed image is displayed in the image sending order, and in the reverse direction, in the image sending order Display the previous image of the currently displayed image.

  The right button depression of the four-direction button included in the operation unit 70, the clockwise operation of the controller wheel 73, and the touch move (drag or flick) to the right with single touch correspond to the image feed operation in the forward direction. The left button depression of the four-direction button included in the operation unit 70, the counterclockwise operation of the controller wheel 73, and the touch move (drag or flick) in the left direction with single touch correspond to the image feed operation in the reverse direction.

If the operation is an image feed operation, the process advances to step S609; otherwise, the process advances to step S610.
In S609, the next image in the direction in which the image feed instruction is given is read from the recording medium 200 to the memory 32, and is displayed on the display unit 28 in S603.

  In step S610, it is determined whether the input operation is an instruction to end the function. If the instruction is an end, the process ends in step S612. If it is not a command to end, other processing is executed in S611. Examples of the other processing mentioned here include processing for opening a menu screen and processing for displaying an index.

7 and 8 are flowcharts for explaining the processing procedure in the enlargement reproduction mode.
When enlargement reproduction is instructed in step S607, the enlargement reproduction process is started, and in step S701, it is determined whether a touch-down operation has been performed. If there is a touch-down operation, the process advances to step S702; otherwise, the process advances to step S703.
In step S703, it is determined whether or not there is a button input. If there is a button input, the process advances to step S723. If there is no button input, the process returns to step S701 and waits for an input.

In step S723, it is determined whether the input operation is an input for ending the enlarged reproduction. If it is the input of the enlargement reproduction end, the process proceeds to S725, the enlargement reproduction is ended, the image is displayed again in S603, and the input is waited.
If it is determined in S723 that the input is not for the enlargement reproduction end, the other button processing is executed in S724, and the process returns to S701 to wait for the input again. Here, the other button processing includes switching processing of the information display displayed on the display unit 28 and the like.

In S702, it is determined whether or not the touch-down is a two-point touch. If the touch is two points, the process advances to step S704; otherwise, the process advances to step S801.
In S704, a guide (means for moving an enlarged image by displaying a guide for moving an enlarged image by causing a touch move of two touched points (touch positions) in the same direction is displayed). .
In step S705, the coordinates of each touched point are stored in the memory 32, and the process advances to step S706.

  In S706, it is determined whether a pinch operation has been performed. If the pinch operation is performed, the process advances to step S707 to perform enlargement (pinch out) / reduction (pinch in) processing according to the direction of the pinch, change the enlargement ratio (display ratio) according to the magnification instruction, and update the display.

  Subsequently, at S709, the enlargement factor after the enlargement / reduction process is stored in the memory 32, and at S710, a pinch execution flag (held in the system memory 52) for storing whether the pinch operation has been performed is set to ON.

If there is no pinch operation at S706, it is determined at S708 whether one of the two points touched is touched up. If one point is touched up, the process advances to step S801. If one point is not touched up, the process advances to step S 712 to determine whether all points touched have been touched up.
If all points have been touched up, the process advances to step S713. If not, the process returns to S706 and continues processing.

  In step S713, the system memory 52 is referenced to determine whether the pinch execution flag is set to ON. If it is set to ON, the process proceeds to S714, the pinch execution flag is set to OFF, and the process returns to S701 and waits for an input. If it is determined in step S713 that the pinch execution flag is not ON, the process advances to step S715 to determine whether the operation performed until all touch-up is touch move in the same direction at two points touched .

  More specifically, the coordinates of the two points stored in the system memory 52 when the two-point touch starts and the coordinates (touch-up points) of the two points immediately before the all-point touch-up is detected in S712 are respectively determined. If there is a difference greater than the distance, it is determined that there are two touch moves. Then, when the directions of the maximum components of the respective differences (one of upper, lower, left, and right) are the same, it is determined that there is a touch move in the same direction.

If it is a touch move in the same direction, the process advances to step S716. If not, the process returns to step S701 and waits for an input.
In S716, it is determined whether the touch move operation is a touch move of a predetermined distance or more, and if it is the predetermined distance or more, the process proceeds to S717. If the distance is not equal to or greater than the predetermined distance, the process advances to step S722, another touch process is performed, and the process returns to step S701 to wait for an input again. In the other touch processing at this time, for example, functions such as deletion of the displayed image and addition of a favorite mark may be executed.

In S717, it is determined whether a touch move of a predetermined distance or more is in the horizontal direction. If it is the horizontal direction, the process proceeds to S718, and if not, the process proceeds to S722.
In S718, it is determined whether the amount of movement of the touch move that is equal to or greater than a predetermined distance is a movement in the forward direction (rightward direction). In the case of the forward direction, the process advances to step S719, advances the image number N by one, and proceeds to step S721 to execute enlarged image sending processing.

As a result, as described with reference to FIGS. 5A and 5B, the enlarged image sending by the two-point touch is performed.
On the other hand, if it is not the positive direction (in the negative direction, that is, the left direction), the process of reducing the image number N by 1 is performed in S720, and the enlarged image sending process is performed in S721.

  As described above, since the enlarged image sending is performed after the all-point touch up, the enlarged position of the image is not changed during the touch operation at the two points. Therefore, when the enlarged image is to be fed, it is possible to prevent the enlargement position from being shifted between the preceding and succeeding images.

  On the other hand, if it is determined in step S702 that the touch is not a two-point touch, the process advances to step S801 to store the coordinates of one point being touched in the system memory 52. After that, it is determined in S802 whether or not the touch move is performed. If the touch move is performed, the process proceeds to S803.

  In step S803, it is determined whether hover detection is performed separately from one touch-moved point. Hover detection is proximity detection as to whether or not an operation object such as a pen or a finger approaches a position on the top surface of the touch panel several millimeters or so (hover status). In the case of a capacitive touch panel, it is determined that there is a hover when a capacitance that exceeds the threshold for hover detection that is lower than the threshold that is determined to be touched is detected.

  If hover detection has been performed, the process advances to step S 807 to determine whether another touchdown (ie, second touchdown) has been performed. If it is determined that another touchdown has been made, the process advances to step S704 to display a guide for enlarged image feed. In the present embodiment, it is assumed that it is determined that the second touchdown has been performed within a predetermined time.

  If one more point is not touched down in step S807, it is determined in step S809 whether or not the touch up is performed. If the touch-up is made (that is, if a touch-off state where one point is not touched is reached), the process advances to step S701 to wait for an input. If it is determined in step S809 that the touch-up has not been made, the process returns to step S803 to determine again whether or not there is a hover detection.

If hover detection is not detected in step S803, the process advances to step S805 to move an enlarged position in the image according to the amount of movement by touch movement. Thereafter, the enlarged center coordinates after movement are stored in the memory 32 in step S806, and the process advances to step S807.
As described above, even when there is a touch move, when the hover is detected (in the case of Yes in S803), the movement of the enlargement position (the process of S805) is not performed. This is because there is a possibility that the hover detection is in the process of approaching a finger for performing the second touch in order to issue an instruction to feed an enlarged image.

  If the enlargement position changes while trying to specify a touch move at two points, the state before the two-point touch move is attempted, and the enlargement position shifts after the enlargement image feed is performed. . However, in the process of trying to perform a touch move at two points by not moving the expanded position when hover detection is performed, that is, moving the expanded position unless it is a touch move with a clear single touch. It is possible to prevent the enlargement position from being unintentionally shifted.

If it is determined in S802 that the touch move has not been performed, the process proceeds to S804, and it is determined whether another touchdown (that is, the second touchdown) has been performed. If it seems that the touchdown has been performed, the process advances to step S704 to display a guide for feeding an enlarged image.
If another touchdown is not performed in S804, the process proceeds to S810 to determine whether touch on is performed for a predetermined time or more without touch move (that is, whether there is a long touch in a single touch) Determine whether or not

If it is determined that touch-on has been performed for a predetermined time or more, the process advances to step S811; otherwise, the process returns to step S802.
In step S811, a guide indicating an operation method for feeding an enlarged image by touch operation after the long touch is displayed. In this case, after the touch-on for a predetermined time or more is continued (that is, after a long touch), it is displayed on the guide that the image can be switched while being enlarged by performing the touch move in the horizontal direction (right or left).

After the guide is displayed, the process waits for an input until touch move is performed in step S812, and when the touch move is performed, the process advances to step S813.
In S813, it is determined whether the operated touch move is in the horizontal direction. If it is horizontal, step S814 follows. If it is not horizontal, step S818 follows to execute other touch processing, and then step S701 to wait for input.

  In step S814, it is determined whether the touch move movement has been in the positive direction. If it is the forward direction, the image number N is advanced by one at S815, and if it is not the forward direction, the image number N is returned to the previous one at S816. Thereafter, the process advances to step S817 to execute enlarged image sending processing, and then returns to step S701 to wait for input.

Details of the enlarged image sending process in S721 will be described using the flowchart of FIG. This process is realized by expanding the program recorded in the non-volatile memory 56 in the system memory 52 and executing it by the system control unit 50.
When an enlarged image feed is instructed, the N-th image among the images recorded on the recording medium 200 is read into the memory 32 in S901. Thereafter, in S902, the central coordinates of the enlargement and the enlargement magnification stored in the memory 32 are read, and in S903, the image is enlarged and displayed with the central coordinates and the enlargement magnification read in S902.

  In the processing of S802 to S807, if there is a one-point touch move in a state where hover detection is not performed, the enlargement position movement is executed in S805. After that, when the second touchdown is detected, the process advances to step S704, and the state where the two touchdowned points are touch-moved in the same direction is selected to receive the enlarged image sending.

  In this case, even if enlargement image sending is instructed thereafter, there is a possibility that the enlargement position is moved without the operator's intention in S805, and there is a fear that the enlargement position may be shifted between the images before and after the enlargement image sending. There is. As this solution method, it is conceivable to determine whether the touch move has been performed for a predetermined distance or more or for a predetermined time or more before executing the enlargement position movement process in S805. In this case, since it can be determined that the operator explicitly intends to move the enlargement position, the enlargement image can be fed without being moved the intention.
