Description

  The present invention enables an image display system and an image display method for sending image information of a subject from a server computer to a terminal device via a communication network, and particularly enables the subject to be instantaneously switched to a desired viewpoint on the terminal device side. The present invention relates to an image display system and an image display method.

  Conventionally, online shopping via the Internet, so-called online shopping, has become widespread. In this online shopping, for example, product image information prepared by the product provider side is stored in a server computer, and the purchaser side displays the image information on its own terminal device via the Internet network for confirmation. . Here, there are still images and moving images as image information, but usually still images tend to be used.

  The image information prepared by the product provider tends to be created with a strong intention of the provider to improve the appearance of the product. Some are designed to be easily understood by the purchaser, but are not necessarily product images photographed from the viewpoint / angle that the purchaser wants to see. In other words, the purchaser wants to obtain the image information instantly so that he can actually pick up the product and observe the product from all angles and viewpoints, up, down, left and right, but this is not possible with current online shopping. It is.

  Some of them have been designed to improve the convenience of observing products on the purchaser's side by preparing many still images taken from various viewpoints and angles, or by taking pictures from all angles up and down, left and right and back and forth without interruption. However, even in these cases, it is difficult for the purchaser to find an image he / she wants to see instantly. That is, in order to find a desired image from many still images, the purchaser himself is forced to perform a cumbersome task of selecting it visually. In the case of moving images, the flow of shooting usually reflects the intention of the provider, so the purchaser waits until the desired image is displayed, or makes full use of the fast-forward function and rewind function. Therefore, it is necessary to find a desired image, and it is forced to carry out troublesome operations and work, and is also subjected to a mental load. The production of moving images and the preparation of a large number of still images on the provider side also require a lot of work time and cost.

  In recent years, as the resolution of images increases, the image capacity has been increasing. For this reason, the load on the hardware side related to image transmission and output display is also increasing. The latest terminal device equipped with a CPU capable of high-speed arithmetic processing and a large-capacity storage device can cope with this load appropriately, but it is a somewhat outdated terminal device or a low-priced terminal with poor performance. In the device, the influence of the load is large, and the image processing speed may be significantly reduced, or the image may not be output and displayed normally. In the worst case, the system on the terminal device side may be down. In particular, in a terminal device such as a smartphone, this tendency is remarkable because it is in a narrow band environment where the communication speed is slow rather than broadband.

  Japanese Laid-Open Patent Publication No. 2013-61817 (Patent Document 1 below) provides a large-scale paper browsing function that prepares two types of base image data with low resolution and detailed image data with the highest resolution and sends an image to the terminal device side. A system has been proposed. This system prepares two types of low resolution base image data and maximum resolution detailed image data, and sends an image to the terminal device in response to a request.

  In the above-mentioned Patent Document 1, two types of low resolution base image data and maximum resolution detailed image data are prepared and transmitted to the terminal device side. This is merely a concept of dividing data into two types of resolutions and sending them in response to a request on the terminal device side.

  In Non-Patent Document 1, since full-size image data is transmitted, the influence of the load is large as described above, and the image processing speed is significantly reduced.

As described above, by preparing many still images of products taken from various viewpoints and angles, or by taking pictures from all angles up, down, left and right without interruption by moving images, the convenience of product observation on the purchaser side is improved. Some have been planned. However, in order to extract and select an image that the purchaser wants to see, the terminal device side is forced to perform troublesome operations and work and takes time, and the purchaser is forced to have a physical and mental load. . Since the purchaser is forced to physically and mentally load, the purchaser does not arrive at the desired image, but gives up on the way and moves to a site where other products are posted. There was also. Such a situation also causes a potential customer to be missed for the provider side. On the provider side as well, the production of moving images and the preparation of a large number of still images require a great deal of work and cost, and impose a considerable load.
In addition, as the image capacity is increased by increasing the resolution of the image, the load on the hardware regarding the image transmission speed and the output display state is also increasing. For this reason, in the case of a somewhat outdated terminal device or a terminal device such as a low-priced version that is inferior in performance, there is a possibility that the image is not able to be processed quickly and appropriately because the influence of the load is large. In particular, in a terminal device such as a smartphone, this tendency is remarkable because it is in a narrow band environment where the communication speed is slow rather than broadband.

  The present invention has been made in view of the above circumstances, and solves the above-described problems, and various viewpoints even in an environment where the communication speed is low without changing the hardware of an existing communication network system.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, an image display system according to the present embodiment includes a server computer (hereinafter referred to as “server”) 100 and a plurality of terminals connected to the server 100 via a communication network 200 such as an Internet line. The device 300 is configured.

As shown in FIG. 2, the server 100 stores a central control processing unit 110 that controls the control of the entire system, and other various areas that the central control processing unit 110 accesses and refers to and performs work. The storage unit 130 having a function, the input unit 150 having a function of inputting various types of information to the server 100 or receiving various types of information transmitted from the outside of the terminal device 300, and the like. An output unit 170 having a function of transmitting information or outputting and displaying is connected via a signal line 190.
When the server 100 receives instruction information for instructing a request to send an image information group related to the subject from the terminal device 300 via the input unit 150, the server 100 first relates to the image information group with a small data capacity ( The low-resolution image information group) is transmitted to the terminal device 300, and then the image information group (high-resolution image information group) having a large data capacity is transmitted.

  The storage unit 130 stores a program storage area 132 for storing various program information to be accessed and referred to by the central control processing unit 110, a work area 134 for performing various operations, and a temporary storage for information. It has a temporary storage area 136 and an image information storage area 138 for storing an image information group. Here, the image information storage area 138 includes an image data area 138a for storing image data of an image information group and a table area 138b for storing incidental information related to the image data in a table format.

Thus, in the image data area 138a, for example, still image data shot from various viewpoints by the imaging apparatus 400 described later, for example, shot from different viewpoints for the subject A, is processed in a predetermined order. Thirty pieces are stored as a lump (that is, an image group) as if they were arranged in a tile on a sheet. Similarly, with respect to the subject B, 30 pieces of still image data shot and processed from different viewpoints are stored in a lump as if they were arranged in a tile on a single sheet in a predetermined order. Yes. That is, in the image data area 138a, still image data photographed and processed from various different viewpoints for one subject are arranged in a predetermined order as if they were tiled on one sheet. 30 are stored.
Each data is composed of two types so as to be the same size as that displayed on the terminal device 300 side and twice the size, and has undergone adjustment processing such as color and shadow. . Here, with regard to adjustment / correction of colors, shadows, etc., for example, in the case of shadows, processing is performed so as to average all data for each subject. Also, the same color is cut out as a background.
Specifically, in this embodiment, the color is adjusted for each vertical angle. That is, the appearance changes slightly depending on how the light hits the subject when shooting. Color adjustment is performed by changing parameters for each angle. For example, in the rotating plate 420 described later, since light is attenuated when photographing from a lower angle, the color is adjusted to be bright and dark. Note that the color adjustment can be collectively changed for a specified image (for example, specified as vertical α ° to β ° and horizontal α ° to β °). This is because the cost is more efficient in terms of time than the correction of each sheet.

  For the image group stored in the image data area 138a, the central control processing unit 110 refers to a predetermined program based on the instruction information from the terminal device 300 and searches the image data area 138a to extract the corresponding image group. It is a target.

  As shown in FIG. 3, the terminal device 300 includes a control unit 320 that controls the entire terminal device, an input / output unit 340 that processes input / output information of the terminal device 300, and a storage unit 360 that stores various types of information. These are provided internally and are connected via a signal line 380. As this terminal device 300, there exist various things, such as a personal computer, a smart phone, a tablet-type terminal device, for example. The input / output unit 340 has a function of sending instruction information to send a desired image information group to the server 100, and a function of outputting and displaying the desired image information group sent from the server 100.

  Next, the image capturing apparatus 400 will be described with reference to FIG. 4 regarding still image data captured from different viewpoints for each subject.

The photographing apparatus 400 includes a turntable 420 for placing a subject, a digital camera 440 for photographing a subject placed on the turntable 420, and a horizontal plane (X) of the turntable 420. It is comprised from the curved attachment part (stand) 460 attached so that a movement to a perpendicular direction (Y) is possible.
The turntable 420 is a turntable that is positioned horizontally and is rotatable in the horizontal direction, for example, made of high-performance transmissive glass with a thickness of 3 mm that transmits 98% of light. By using such a turntable, it is possible to adjust the reflection / refractive index of light from the turntable as if the subject is floating in the air even when shooting from below. Here, the turntable 420 can rotate at an arbitrary angle around the vertical rotation axis Y, the horizontal angle is x, and the vertical angle is y. The turntable 420 is not limited to the material for the turntable.
The mounting portion 460 can move the camera 440 in increments of, for example, 20 ° with respect to the vertical direction when the Y axis is the vertical direction with respect to the horizontal plane of the turntable 420, the upper direction is plus (+), and the lower direction is minus (−). It can be attached to. That is, if the state of the subject A placed on the rotating plate 420 from + 90 ° is + 90 °, + 20 °, ± 0 °, −20 °, −40 ° in order of 20 ° with + 40 ° being the highest position. The camera 440 is movably mounted at the position. In this embodiment, the angle of the attachment position is in the range of + 40 ° to −40 °, but may be in the range of + 90 ° to −90 ° or may be in another range. Further, although the angle of the mounting position is set in increments of 20 °, it may of course be changed in increments of 10 ° or 15 ° and can be appropriately changed.

The photographing of the subject by the photographing apparatus 400 is performed according to the flow shown in FIG.
First, photographing is performed in a state where the camera 440 is mounted on the mounting portion 460 (x = 0 °) so as to be positioned at 50 ° from above the subject (vertical direction with respect to the turntable 420 + 40 °, ie, y = + 40 °). Is performed (step S502). Next, as shown in FIG. 4 (arrow x direction), the rotating disk 420 is rotated 60 ° counterclockwise as viewed from above (x = 60 °) and photographed (step S504). Subsequently, similarly, the rotating disk 420 is further rotated counterclockwise by 60 ° (rotation of a total of 120 °, that is, x = 120 °) and photographed. Similarly, the imaging is repeated until the turntable 420 makes one round in increments of 60 ° (until x = 360 °) (step S506). Since one round is the same as the initial state (x = 0 °), shooting in this state is not performed. Accordingly, six shootings are performed at a position of + 40 ° (y = + 40 °) in the vertical direction. These are six still images when y = + 40 °. The still image is subjected to compression processing (step S508).
Subsequently, photographing is performed in a state where the camera 440 is attached to the attachment portion 460 so as to be positioned at + 20 ° in the vertical direction with respect to the horizontal plane of the turntable 420, that is, y = + 20 ° (x = 0 °) (step). N of S510, step S502). Next, as shown in FIG. 4 (arrow x direction), the rotating disk 420 is rotated 60 ° counterclockwise as viewed from above (x = 60 °) and photographed (step S504). This procedure is repeated until the turntable 420 makes one round. Since one round is the same as in the initial state (x = 0 °), no shooting is performed as described above. Accordingly, six shootings are performed at a position of + 20 ° (y = + 20 °) in the vertical direction. These are six still images when y = + 20 °. Thereafter, the camera 440 is attached to the attachment portion 460 at a position where the vertical shooting angle, that is, y is ± 0 °, −20 °, and −40 °, and the same processing is repeated to generate a still image subjected to compression processing. It will be. Thus, 5 × 6 = 30 shots are taken for one subject, and 30 still images are obtained as compressed images, and these are adjusted and corrected for color and shadow, respectively. At the same time (step S512), two types of resolution (low resolution data) and double size (high resolution data) of the same size as at the time of display are prepared (step S514) as one image data block. All 30 images are further compressed in the image data area 148a and stored as if they were arranged in a tile on one sheet in the order of photographing.

  FIG. 6 is a diagram conceptually showing an example of image data photographed by the above procedure. The image data 601, 602, and 603 are still images captured by installing the camera 440 at a position where the shooting angle in the vertical direction is y = + 40 °. That is, the image data 601 has a horizontal shooting angle x = 0 °, the image data 602 has a horizontal shooting angle x = 60 °, and the image data 603 has a horizontal shooting angle x = 300 °.

  The operation of the above configuration will be described below with reference to FIGS.

  First, when the terminal device 300 connects to the communication network 200, accesses the server 100, and requests the server 100 to send, for example, an image group of the subject A (step S702 in FIG. 7), the server 100 reads the image data. An image group corresponding to the subject A is selected from the image group stored in the area 138a (step S704), and an image having a smaller data capacity (that is, low resolution data) among the image group is transmitted first. Downloading is started (step S706). While an image with a small data capacity is stored in the storage unit 360 of the terminal device 300 and output and displayed on the input / output display unit 340, the server 100 continues the image with the larger data capacity (ie, high resolution data). (Step S708). When the terminal device 300 stores the image data having a large data capacity in the storage unit 360 and is output and displayed by the input / output display unit 340, the terminal device 300 does not hold the image data having the small data capacity that has been output and displayed until then. Discard (step S710) and download of the desired image group is completed.

Next, the image of the initial position of the subject A displayed on, for example, the touch panel type input / output unit 340 of the terminal device 300 is touched with a stylus (touch pen) P or a finger (Y in step S802 in FIG. 8, FIG. 9 ( When a drag operation is performed to a desired position as it is (see step a804), the movement distances in the x-axis direction and the y-axis direction from the position where the touch operation was first performed to the dragged position are determined by the control unit. 330 is calculated with reference to a predetermined program stored in the storage unit 360 (step S806). Based on this moving distance, the terminal device 300 searches and extracts corresponding image data from the image group downloaded by the control unit 320 to the storage unit 360 (step S808), and switches from the front image to input / output unit 340. Are output and displayed (step S810, see FIG. 9B).
Further, when the touch operation and the drag operation are performed, the processing flow shown in FIG. 8 (steps S802 to S808) is performed, and a new image corresponding to the movement distance of the drag operation is displayed on the input / output unit 340 of the terminal device 300. Will be output. Therefore, the images taken from various viewpoints of the subject A are switched instantaneously with the drag operation and output to the input / output unit 340 of the terminal device 300 as if the subject A was observed from the top, bottom, left, and right. Will be displayed. The image display is switched by the stylus (touch pen) P or a finger, but it goes without saying that the image display may be switched by a pointer moving operation using a mouse.

  Here, with reference to FIG. 10 and FIG. 11, the image switching process by dragging the touched display image (the process from step S806 to step S810) will be described in detail.

  As shown in FIG. 10, a group of images is arranged like a square sheet in a tiled manner, and each image is given a number starting from 0 in the vertical and horizontal directions. A coordinate axis corresponding to the position pointed by the stylus or mouse is assigned. The maximum value of the coordinate axis is set to an arbitrary fixed value. Thus, the position on the coordinate axis is calculated according to the following rule (A) from the movement amount when the drag operation is performed, and the image number of the image to be displayed is derived. The amount of movement is calculated separately in the vertical direction and the horizontal direction.

Rule (A)
Position = position + drag movement amount When loop is enabled:
Position = remainder obtained by dividing position by maximum position When position <0
Position = Position + Maximum position value If the loop is not active:
When position <0
Position = 0
When position> maximum position
Position = Maximum position value Image number = Number of images x Position / Maximum position value Image number = Number rounded down to the nearest decimal point

For example, as shown in FIG. 11A, when the initial position is “position = 150”, “image number = 6 (number of images) × 150 (position) ÷ 300 (maximum position value) = 3”.
As shown in FIG. 11B, when 80 px is dragged to the right, “position = 150 × 80 = 230” is obtained, and “image number = 6 (number of images) × 230 (position) ÷ 300 (maximum position value)” = 4. .6 → 4 (number rounded down).
As shown in FIG. 11C, when the user drags 80 px further (in the case of no loop), “position = 230 + 80 = 310 → 300 (maximum value 300)” is obtained, and “image number = 6 (number of images) × 300”. (Position) ÷ 300 (maximum position value) = 5 ”.
As shown in FIG. 11D, when there is a loop, “position = 230 + 80 = 310 → 10 (remainder divided by maximum value 300)” and “image number = 6 × 10 ÷ 300 = 0.6 → 0 (number rounded down).
Note that the case where the loop is effective intends an image photographed over one round of 0 ° to 360 ° in the X-axis direction, for example, like the turntable 420. Further, the case where the loop is not effective means that the position of the camera 440 attached to the stand 460 is within a limited range such as −40 ° to + 40 ° rather than over the entire circumference in the Y-axis direction. This is intended for a photographed image. Alternatively, for example, an image photographed within a limited range, such as −60 ° to + 60 °, is not intended over one turn in the X-axis direction of the turntable 420.

According to the above embodiment, desired image information can be quickly output and displayed on the terminal device side from a group of image information of subjects photographed from various viewpoints with simple operations, and images of subjects from other viewpoints can be displayed. Since changes and switching to information can be quickly output and displayed on the terminal device side with a simple operation, it is easy to use and easy to use. Further, unlike the conventional case, the operator on the terminal device side can sufficiently observe the subject without being physically and mentally burdened. Moreover, it can be realized even in an environment where the communication speed is low without changing the hardware of the existing communication network system, so that it is practical and economical.
In addition, the low resolution image is output and displayed first, and then the high resolution image is output and displayed, so that the image display on the terminal device side is performed smoothly and the stress on the user is eliminated. is there.

  Next, another embodiment of the present invention will be described below with reference to the drawings.

  As shown in FIG. 12, the image display system according to the present embodiment includes a server computer (hereinafter referred to as “server”) 500 and a plurality of terminals connected to the server 500 via a communication network 600 such as an Internet line. And a device 700.

As shown in FIG. 13, the server 500 stores a central control processing unit 510 that performs control processing of the entire system, and other various areas that the central control processing unit 510 accesses and refers to and performs work. A storage unit 530 having a function, an input unit 550 having a function of inputting various types of information to the server 500 and receiving various types of information transmitted from the outside of the terminal device 700, and various types of information from the server 500 to the outside An output unit 570 having a function of sending information or outputting and displaying is connected via a signal line 590.
When the server 500 receives, via the input unit 550, instruction information for instructing a request to transmit the image information group related to the subject from the terminal device 700, the server 500 first relates to the image information group (the image information group with a small data capacity ( The low-resolution image information group) is transmitted to the terminal device 700, and then the image information group (high-resolution image information group) having a large data capacity is transmitted.

  The storage unit 530 stores a program storage area 532 for storing various program information to be accessed and referenced by the central control processing unit 510, a work area 534 for performing various operations, and a temporary storage for information. It has a temporary storage area 536 and an image information storage area 538 for storing an image information group. Here, the image information storage area 538 includes an image data area 538a for storing image data of an image information group and a table area 538b for storing incidental information related to the image data in a table format.

Thus, in the image data area 538a, for example, still image data taken from various viewpoints, for example, taken from different viewpoints with respect to the subject A, is processed as if in a predetermined order. 684 pieces are stored as a lump (that is, an image group) as if they were arranged in a tile on a sheet. Similarly, for the subject B, 684 pieces of still image data shot and processed from different viewpoints are stored in a lump as if they were arranged in a tile on a single sheet in a predetermined order. Yes. That is, in the image data area 538a, still image data shot and processed from various different viewpoints for one subject are arranged in a predetermined order as if they were tiled on one sheet. 684 are stored.
Each data is composed of two types so as to be the same size as that displayed on the terminal device 700 side and twice the size, and the color and shadow adjustment / correction processing is performed. . Here, with regard to adjustment / correction of colors, shadows, etc., for example, in the case of shadows, processing is performed so as to average all data for each subject. Also, the same color is cut out as a background.
Specifically, in this embodiment, the color is adjusted for each vertical angle. That is, the appearance changes slightly depending on how the light hits the subject when shooting. Color adjustment is performed by changing parameters for each angle. For example, in a rotating plate 820 to be described later, light is attenuated when shooting from a lower angle, so that the color is adjusted to be brighter and darker. Note that the color adjustment can be collectively changed for a specified image (for example, specified as vertical α ° to β ° and horizontal α ° to β °). This is because the cost is more efficient in terms of time than the correction of each sheet.

  The image group stored in the image data area 538a is extracted from the image data area 538a by the central control processing unit 510 referring to a predetermined program based on the instruction information from the terminal device 700. It is a target.

  As shown in FIG. 14, the terminal device 700 includes a control unit 720 that controls the entire terminal device, an input / output unit 740 that processes input / output information of the terminal device 700, and a storage unit 760 that stores various types of information. They are provided internally and are connected via a signal line 780. As this terminal device 700, there exist various things, such as a personal computer, a smart phone, a tablet-type terminal device, for example. The input / output unit 740 has a function of sending instruction information to send a desired image information group to the server 500, and a function of outputting and displaying the desired image information group sent from the server 500.

  Next, the image capturing apparatus 800 will be described with reference to FIG. 15 regarding still image data captured from different viewpoints for each subject.

The photographing apparatus 800 includes a turntable 820 for placing a subject, a digital camera 840 for photographing a subject placed on the turntable 820, and the horizontal plane (X) of the turntable 820. It is comprised from the curved attachment part (stand) 860 attached so that a movement to a perpendicular direction (Y) is possible.
The turntable 820 is a turntable that is horizontally rotatable and is made of, for example, a high-performance transmissive glass having a thickness of 3 mm that transmits 98% of light. By using such a turntable, it is possible to adjust the reflection / refractive index of light from the turntable as if the subject is floating in the air even when shooting from below. Here, the turntable 820 can rotate at an arbitrary angle around the vertical rotation axis Y, the horizontal angle is x, and the vertical angle is y. The turntable 820 is not limited to the turntable material.
The mounting portion 860 can move the camera 840 in increments of 10 ° with respect to the vertical direction, for example, when the vertical direction with respect to the horizontal plane of the turntable 820 is the Y axis, the upper side is plus (+), and the lower side is minus (−). It can be attached to. That is, the photographing state from right above the subject A placed on the rotating plate 820 is + 90 °, and in order of 10 °, + 80 °, + 70 °, + 60 °, + 50 °, + 40 °, + 30 °, + 20 °, The camera 840 can be moved at positions of + 10 °, ± 0 °, −10 °, −20 °, −30 °, −40 °, −50 °, −60 °, −70 ° −80 °, and −90 °. It is configured to be attached to. In the present embodiment, the angle of the attachment position is in the range of + 90 ° to −90 °, but may be in the range of + 80 ° to −80 ° or another range. Further, although the angle of the mounting position is set in increments of 10 °, it may be changed in increments of 15 ° or 20 °, and can be changed as appropriate.

The photographing of the subject by the photographing apparatus 800 is performed according to the flow shown in FIG.
First, photographing is performed with the camera 840 mounted on the mounting portion 860 (x = 0 °) so as to be positioned directly above the subject (vertical direction + 90 °, ie, y = + 90 °) (step S1602). . Next, as shown in FIG. 15 (in the direction of arrow X), the rotating disk 820 is rotated counterclockwise by 10 ° when viewed from above (x = 10 °) and photographed (step S1604). Subsequently, similarly, the rotating disk 820 is further rotated counterclockwise by 10 ° (rotation of a total of 20 °, that is, x = 20 °) and photographed. Similarly, the imaging is repeated until the turntable 820 makes one round in increments of 10 ° (until x = 360 °) (step S1606). Since one round is the same as the initial state (x = 0 °), shooting in this state is not performed. Accordingly, the photographing is performed 36 times at a position of + 90 ° (y = + 90 °) in the vertical direction. These are 36 still images when y = + 90 °. The still image is subjected to compression processing (step S1608).
Subsequently, photographing is performed in a state where the camera 840 is attached to the attachment portion 860 so as to be positioned at + 80 ° in the vertical direction with respect to the horizontal plane of the turntable 820, that is, y = + 80 ° (x = 0 °) (step). N of S1610, step S1602). Next, as shown in FIG. 15 (in the direction of arrow X), the rotating disk 820 is rotated counterclockwise by 10 ° when viewed from above (x = 10 °) and photographed (step S1604). This procedure is repeated until the turntable 820 makes one round. Since one round is the same as in the initial state (x = 0 °), no shooting is performed as described above. Accordingly, the photographing is performed 36 times at a position of + 80 ° (y = + 80 °) in the vertical direction. These are 36 still images when y = + 80 °. Hereinafter, the vertical shooting angle, that is, y is + 70 °, + 60 °, + 50 °, + 40 °, + 30 °, + 20 °, + 10 °, ± 0 °, −10 °, −20 °, −30 °, −40 The camera 840 is attached to the attachment portion 860 at the positions of °, -50 °, -60 °, -70 ° -80 °, and -90 °, and the same processing is repeated to generate a still image subjected to compression processing. Become. Thus, 19 × 36 = 684 shots were taken for one subject, and 684 still images were obtained after compression processing, and these were adjusted and corrected for color and shadow, respectively. At the same time (step S1612), two types of data having the same size as the display (low resolution data) and double size (high resolution data) are prepared (step S1614). The images are further compressed in the image data area 548a and stored in the order of photographing as if they were arranged in a tile on one sheet.

  FIG. 17 is a diagram conceptually showing an example of image data photographed by the above procedure. The image data 1701 to 1705 are still images captured by installing the camera 840 at a position where the vertical shooting angle is y = + 90 °. The image data 1701 is the horizontal shooting angle x = 0 °, and the image data. 1702 is a horizontal shooting angle x = 20 °, image data 1703 is a horizontal shooting angle x = 40 °, image data 1704 is a horizontal shooting angle x = 60 °, and image data 1705 is a horizontal shooting angle x. = 340 °. Similarly, the image data 1711 to 1715 are still images captured by setting the camera 840 at a position where the vertical shooting angle is y = + 60 °, and the image data 1711 is the horizontal shooting angle x = 0 °, The image data 1712 is the horizontal shooting angle x = 20 °, the image data 1713 is the horizontal shooting angle x = 40 °, the image data 1714 is the horizontal shooting angle x = 60 °, and the image data 1715 is the horizontal shooting. The angle x = 340 °.

  The operation of the above configuration will be described below with reference to FIGS.

  First, when the terminal device 700 connects to the communication network 600, accesses the server 500, and requests the server 500 to send, for example, an image group of the subject A (step S1802 in FIG. 18), the server 500 reads the image data. An image group corresponding to the subject A is selected from the image groups stored in the area 538a (step S1804), and the image having the smaller data capacity is sent first, and download is started (step S1804). S1806). While an image with a smaller data capacity is stored in the storage unit 760 of the terminal device 700 and output and displayed on the input / output display unit 740, the server 500 continues to transmit an image with a larger data capacity (step S1808). . When the terminal device 700 stores image data with a large data capacity in the storage unit 760 and outputs and displays it on the input / output display unit 740, the terminal device 700 does not hold the image data with the small data capacity that has been output and displayed until then. Discard (step S1810) and download of the desired image group is completed.

Next, the front image of the subject A displayed on, for example, the touch panel type input / output unit 740 of the terminal device 700 is touched with a stylus (touch pen) P or a finger (Y in step S1902 in FIG. 19), and the desired position is directly maintained. When the drag operation is performed (Y in step S1904), the control unit 730 stores the movement distances in the x-axis direction and the y-axis direction from the position where the touch operation was first performed to the dragged position in the storage unit 760. It is calculated with reference to a predetermined program (step S1906). Based on this moving distance, the terminal device 700 searches and extracts corresponding image data from the image group downloaded to the storage unit 760 by the control unit 720 (step S1908), and switches from the front image to input / output unit 740. Is output and displayed (step S1910).
Furthermore, when a touch operation and a drag operation are performed, the processing flow shown in FIG. 19 (steps S1902 to S1908) is performed, and a new image corresponding to the movement distance of the drag operation is input / output unit 740 of the terminal device 700. Will be output. Therefore, the images taken from various viewpoints of the subject A are instantaneously switched by the drag operation and output to the input / output unit 740 of the terminal device 700 as if the subject A was observed from the top, bottom, left, and right. Will be displayed.
Here, switching of the image display is performed by the stylus (touch pen) P or a finger, but it is needless to say that it may be performed by a pointer moving operation with a mouse.
The calculation method for selecting from 684 images based on the movement distance is in accordance with the calculation method for selecting from 30 images based on the movement distance in the above-described embodiment.

According to the above embodiment, desired image information can be quickly output and displayed on the terminal device side from a group of image information of subjects photographed from various viewpoints with simple operations, and images of subjects from other viewpoints can be displayed. Since changes and switching to information can be quickly output and displayed on the terminal device side with a simple operation, it is easy to use and easy to use. Further, unlike the conventional case, the operator on the terminal device side can sufficiently observe the subject without being physically and mentally burdened. Moreover, it can be realized even in an environment where the communication speed is low without changing the hardware of the existing communication network system, so that it is practical and economical.
In addition, the low resolution image is output and displayed first, and then the high resolution image is output and displayed, so that the image display on the terminal device side is performed smoothly and the stress on the user is eliminated. is there.

In the above embodiment, as a method for transmitting an image group from the server to the terminal device, first, an image group with a small data capacity (low resolution image group) is transmitted, and the terminal device displays the image group. The image group is sent in two stages, in which an image group with a large amount of data (high resolution image group) is subsequently sent, but in three stages or multiple stages so as to send an image group with a higher resolution. It is within the scope of the present invention that images may be sent out. In addition, the images may be thinned out in a range that does not hinder display, and the data of all the images may be transmitted in the order.
In the above embodiment, the image group is handled as if it were a sheet of tiles, but the image group may be handled as if it were a picture-story show.
Further, the data amount may be reduced by cutting out background data of individual image data.
The present invention is not limited to the above-described embodiment, and various modifications are of course possible without departing from the gist of the present invention.
