  Hereinafter, the first to third embodiments will be described. First, an outline of the method of each embodiment will be described, and then a system configuration example will be described. Then, the flow of processing performed in the first to third embodiments will be described using flowcharts and the like. In addition, each embodiment described below does not unduly limit the content of the present invention described in the claims. In addition, all the configurations described in the embodiments are not necessarily essential configuration requirements of the invention.

1. Outline When various image processing is performed on an image, it may take a very long time to complete the image processing depending on the size (resolution) of the output image. For example, when performing processing for generating a panoramic image from a plurality of images, the larger the size of the generated panoramic image, the longer it takes to complete the image processing.

  However, even if the image processing is performed for a long time, the image obtained as a result of the image processing is not always as desired by the user. For example, when generating the panoramic image described above, it is sufficient if the subject is smoothly connected, but in some cases, the input image is mistakenly connected, and the projected image is completely different from the actual subject. May be generated.

  In such a case, the image processing must be performed again, and the time previously spent on the image processing is wasted.

  Therefore, if the user can confirm the preview image of the output image before the image processing is completed, the user can determine whether the result of the image processing is acceptable without waiting for a long time until the image processing is completed.

  When checking the results of image processing, the preview image does not necessarily have the maximum size (maximum resolution). First, check the impression received from the entire image (for example, whether or not a certain subject is reflected). Then, it is considered that the method of enlarging and confirming details (for example, whether panoramic images are smoothly connected, etc.) that the user is interested in afterwards is considered. That is, when confirming the impression received from the entire image, there is no problem even if the preview image is smaller than the display size (display resolution) of the output device. Rather, it is more important for the user that the confirmation can be performed as soon as possible than the size.

  Here, as described above, there are devices disclosed in Patent Literature 1 and Patent Literature 2 as devices that display a plurality of image outputs in response to a user's request.

  In Patent Document 1 described above, images can be sequentially displayed at regular time intervals or at a user-specified timing using a button or the like so that images processed under different conditions (for example, brightness and face size) can be compared and discriminated. An apparatus for displaying is disclosed.

  However, Patent Document 1 does not mention a case where the sizes (resolutions) of images to be transmitted are different.

  Also, in Patent Document 2 described above, a region of interest designated manually or automatically is extracted from a medical diagnostic image, transmitted to the display unit at the maximum size (maximum resolution), and then the surrounding region is imaged at a low resolution. By first transmitting the captured image and sequentially transmitting the captured image with the resolution increased step by step, the user can grasp the relationship with the entire image while giving the attention area priority to the amount of information However, an apparatus that can browse images is disclosed.

  However, in a daily (general) scene such as when generating a panoramic image in the above example, as described above, it is common to check details after checking the entire image. The procedure is reverse to that of the technique disclosed in Patent Document 2. In addition, an image in the middle of processing in the technique disclosed in Patent Document 2 has a different size (resolution) for each region, and an image in which all regions are displayed at the highest resolution and an image in the middle of processing are image impressions. May be different. Therefore, it is not suitable for general use like the previous example.

  As described above, there are devices disclosed in Patent Document 3 and Patent Document 4 as devices that perform input or processing optimal for the display resolution of the output device.

  Patent Document 3 described above discloses a device that performs image quality improvement processing based on the screen resolution of a display device. For example, if the screen resolution is high, the sharpness of the image is reduced, and if the screen resolution is low, the sharpness is increased.

  Further, Patent Document 4 described above discloses a device that adjusts imaging resolution in accordance with display resolution. If the display resolution exceeds the maximum shooting resolution, shooting is performed at the maximum shooting resolution.

  However, in the methods disclosed in Patent Document 3 and Patent Document 4, both can provide an optimal image for the display size, but the user will wait until the optimal image is provided, It is not possible to confirm at an early timing whether an image requested by the user can be obtained.

  Therefore, the server system according to the first embodiment described later is configured so that the second output image having the second output size larger than the first output size is generated or displayed on the display unit of the terminal device. A first output image having a first output size smaller than the two output sizes is transmitted to the terminal device. That is, the first output image is generated as the above-described preview image, and transmitted to the terminal device before the second output image that is a high-resolution image. Thereby, the user can confirm the preview image before a large-sized image (high-resolution image) is generated.

  In addition, in some image processing, the size (resolution) of the second output image cannot be determined unless the image processing is actually performed. One example is panoramic image generation processing.

  Therefore, the server system according to the second embodiment to be described later performs a process of calculating the second output size based on the first output size and generating a second output image.

  Further, if the difference between the first output size and the second output size is larger than a predetermined value, whether or not the second output image is an image that the user wants to acquire simply by confirming the first output image. It may not be possible to judge whether or not.

  Therefore, a server system according to a third embodiment to be described later transmits a third output image having a third output size that is larger than the first output size and smaller than the second output size after the transmission of the first output image. The second output image is transmitted to the terminal device before transmission.

2. System Configuration Example Next, a configuration example of a server system according to a first embodiment to a third embodiment described later will be described with reference to FIG.

  The server system 100 communicates with the terminal device via the network 500. Further, the number of terminal devices that communicate with the server system 100 may be one or plural. For example, FIG. 1 illustrates three terminal devices, a first terminal device 200, a second terminal device 300, and a third terminal device 400, as terminal devices that communicate with the server system 100.

  More specifically, the first terminal device 200 illustrated in FIG. 1 is a smartphone, the second terminal device 300 is a tablet terminal (multifunctional portable terminal), and the third terminal device 400 is a personal computer. It is. However, these are merely examples, and the server system 100 may communicate with terminal devices other than the examples given here.

  The network 500 may be the Internet or an intranet.

  Next, a detailed configuration example of the server system 100 according to the first to third embodiments described later will be described with reference to FIG. FIG. 2 shows an example in which the server system 100 communicates with the first terminal device 200 and the second terminal device 300.

  Server system 100 includes a reception processing unit 110, a processing unit 120, and a transmission processing unit 130. The server system 100 is not limited to the configuration of FIG. 2, and various modifications such as omitting some of these components or adding other components are possible.

  Next, the connection of each part is demonstrated. The reception processing unit 110 is connected to the processing unit 120. The processing unit 120 is connected to the reception processing unit 110 and the transmission processing unit 130. The transmission processing unit 130 is connected to the processing unit 120.

  Next, processing performed in each unit will be described.

  First, the reception processing unit 110 performs processing for receiving information on an input image via a network. For example, the reception processing unit 110 performs processing for receiving input image information from the processing unit 220 of the first terminal device 200 and the processing unit 320 of the second terminal device 300 via the network. Although omitted in FIG. 2, the server system 100 may have an antenna unit, and the reception processing unit 110 and the transmission processing unit 130 control the antenna unit, and the antenna unit is connected to each terminal device. Wireless communication may be performed. Moreover, the server system 100 is not limited to what communicates with each terminal device by radio | wireless, You may communicate with each terminal device with a wire communication.

  Next, the processing unit 120 performs image processing on the input image. Further, the processing unit 120 can include an image processing unit 121 and a control unit 122. The image processing unit 121 actually performs image processing on the input image. The control unit 122 performs processing for specifying various parameters used when the image processing unit 121 performs image processing. The input image may be a still image or a moving image.

  Further, the transmission processing unit 130 performs processing for transmitting information on the output image after the image processing via the network. For example, the transmission processing unit 130 performs processing for transmitting output image information to the processing unit 220 of the first terminal device 200 and the processing unit 320 of the second terminal device 300 via the network.

  The functions of the reception processing unit 110, the processing unit 120, and the transmission processing unit 130 can be realized by hardware such as various processors (CPU and the like), ASIC (gate array and the like), a program, and the like.

  In addition, the first terminal device 200 includes a first display unit 210 and a processing unit 220. Similarly, the second terminal device 300 includes a second display unit 310 and a processing unit 320.

  The processing unit 220 and the processing unit 320 perform processing for communicating with the reception processing unit 110 and the transmission processing unit 130 of the server system 100. In addition, the first display unit 210 and the second display unit 310 display the acquired image. Alternatively, the first terminal device 200 or the second terminal device 300 may receive an image processing result from the image processing unit 121 of the server system 100 and store the image data in an electronic medium.

  Further, the first terminal device 200 or the second terminal device 300 may be configured to be able to capture an image, or may be configured to read video data from an electronic medium.

  Each unit of the server system 100, the first terminal device, and the second terminal device may be connected by a fixed wiring or may be connected by a network. The functions of each unit may be realized as software that operates on a processor.

3. First Embodiment A system configuration example of the present embodiment is as shown in FIGS. First, an outline of processing performed by each unit in the present embodiment will be described.

  First, in the present embodiment, the first terminal device 200 captures an input image and transmits the input image information to the server system 100 via the network. Then, the second terminal apparatus 300 receives the output image information as the image processing result of the server system 100 via the network, and displays the output image on the second display unit 310. Note that the second display portion 310 is a liquid crystal display having a pixel size of width W pixels and height H pixels shown in FIG.

  In the present embodiment, the image processing unit 121 performs, as image processing, filter processing that applies an effect that is captured by a tilt shift lens to an input image. A tilt-shift lens is a technique that corrects image distortion by intentionally tilting or translating the lens optical axis and imaging surface by moving the lens horizontally and vertically. This is the main purpose lens. With this lens, you can adjust the focus and perspective by so-called “tilting” to shoot the subject as if it were a diorama. The image processing unit 121 performs processing for giving the position and range of blurring, the strength and gradient of the blurring effect, and the like, and applies such a diorama effect to the output image. In the image processing performed by the image processing unit 121 in this embodiment, the input image size (resolution) and the output image size (resolution) do not change.

  The control unit 122 is assumed to know in advance the relationship between the processing function of the image processing unit 121, the size of the input image, and the size of the output image.

  Next, the flow of processing of this embodiment will be described using the sequence diagram of FIG. In FIG. 3, for the sake of brevity, the reception processing unit 110 and the transmission processing unit 130 of the server system 100 are omitted, but actually, these processing units perform transmission / reception processing. In addition, each part of the first terminal device 200 and each part of the second terminal device are also omitted from the description for the same reason.

  First, the control unit 122 acquires an upper limit size from the second terminal device 300 (T101). Here, the upper limit size refers to the pixel size of the display panel if the second terminal device 300 includes the second display unit 310. Further, a pixel size larger than the display panel may be acquired as the upper limit size that can be displayed. Here, the width W pixel and the height H pixel, which are the sizes of the display, are acquired as the upper limit size. Or if the 2nd terminal device 300 has a preservation | save function, the upper limit of the pixel size which can be preserve | saved may be sufficient. Further, if the second terminal device 300 has a printing function, it acquires DPI (dots per inch) information, and sets the upper limit pixel size of the image according to information such as color settings and output paper size. It may be calculated.

  Then, when the control unit 122 acquires the upper limit size, the image processing parameters (hereinafter referred to as image processing parameters and so on) are set so that the second output size (the size of the second output image) is equal to or smaller than the upper limit size. Set). Here, the output size for the second time is set to the same value as the upper limit size of width W pixels and height H pixels. Further, the image processing parameters are determined so that the first output size (the size of the first output image) does not exceed the second output size. Here, the first output size is determined to be ½ each of the vertical and horizontal output sizes. That is, the output size for the first time is set to width W / 2 pixels and height H / 2 pixels. In addition, each output size may be selected from a predetermined size so that the first output size is smaller than the second output size, or the user may specify.

  Next, the control unit 122 transmits (notifies) image processing parameters including the size of the image to be processed regarding the first and second output to the image processing unit 121 (T102). Here, the size of the image to be processed is equal to the output size, but may be different when other image processing is performed. Here, the size of the image to be processed is referred to as the size of the image to be processed, and the size of the image received by the reception processing unit 110 is distinguished from the size of the input image. I'm calling. In the present embodiment, resizing processing or the like may be performed on the input image received and processed by the reception processing unit 110, and image processing may be performed after changing the size of the image. This is because they may be different.

  Then, the first terminal device 200 transmits input image data to the image processing unit 121 (T103). Note that the first terminal device 200 may transmit data of a plurality of input images as input image data. For example, the first input image data is transmitted first as the first output image generation data, and the second input image data is transmitted later as the second output image generation data. May be. At this time, the first terminal device 200 may use an image obtained by performing reduction processing or enlargement processing on the original image as the first input image, and use the original image as the second input image. .

  Next, the image processing unit 121 enlarges or reduces the input image as necessary according to the image processing parameters (resizing processing, sizing processing), and filters the diorama effect (T104). Note that the filter parameters of the image processing unit 121 may be selectable by the user via a user interface (not shown in FIG. 2), or other predetermined parameters may be used.

  Thereafter, as illustrated in FIG. 4B, the image processing unit 121 outputs the result of the filter processing to the second terminal device 300 as the first processing result (first output image) (T105). That is, the second terminal apparatus 300 outputs a processing result smaller than the second output size before the processing result of the second output size.

  Further, the image processing unit 121 enlarges or reduces the input image as necessary according to the image processing parameters, filters the diorama effect (T106), and, as shown in FIG. The result of the filter processing is again output to 300 as the second processing result (second output image) (T107).

  Thus, before obtaining the final result, an image having a smaller size (first output image) can be confirmed as an intermediate result at an earlier timing, and the user can reduce the stress of waiting for the processing result. Furthermore, it is possible to determine at an early timing whether the processing result is in accordance with the user's intention.

  Note that the image processing performed at T106 is the same processing as the image processing performed when the first output image is generated when there is no parameter change instruction to be described later. Therefore, although the first output image and the second output image are different in size, the content itself shown in the image is the same. That is, the first output image can be used as a preview image of the second output image.

  However, if the user confirms the first output image and determines that the image does not conform to the user's intention, the user can interrupt the second image processing via a user interface (not shown). Alternatively, it may be possible to request reprocessing by changing filter parameters. For example, after checking the processing result of the first time, if it is different from the image of the image that the user wants to acquire, change the blur range and the parameter to set the blur position so that reprocessing can be requested Good.

4). Second Embodiment A system configuration example of the present embodiment is as shown in FIGS. First, differences from the above-described first embodiment will be described.

  First, the image processing unit 121 of the present embodiment performs a panorama image generation process (panorama synthesis process). In the panorama image generation process, a plurality of input images are associated with feature points and the like, geometrically transformed, and combined into a single image. First, techniques such as SIFT (Scale-Invariant Feature Transform) and SURF (Speeded Up Robust Feature) are used for feature point extraction and association. However, the method is not limited to these, and any method may be used. In addition, a matching process using a template may be performed. Then, a geometric transformation matrix is estimated from a pair of feature points associated with each other by using a technique such as RANSAC (RANdom SAmple Consensus).

  Here, it is assumed that two input images of the same size are panorama synthesized, and the size (input size) of the input image is a height H ′ and a width W ′. Here, the input size refers to the size of an image that is directly input to the panoramic image generation process.

  In order to simplify the description, it is assumed that the two input images always have overlapping areas of W ′ / 2 or more in the width direction and H ′ / 2 or more in the height direction as shown in FIG. . FIG. 7 shows the relationship between the input size and the output size when such a condition is satisfied. When the display size of the second display unit 310 of the second terminal device 300 is the width W and the height H, the maximum size of the composite image is also the width W and the height H. W ′ + ½W ′ ≦ W and H ′ + ½H ′ ≦ H must be satisfied. That is, it is necessary to satisfy H ′ ≦ 2 / 3H and W ′ ≦ 2 / 3W. Therefore, in order to obtain a composite result smaller than the display size of the second display unit 310, the input size is set to be smaller than the height 2 / 3H and the width 2 / 3W. However, this does not guarantee that the panorama synthesis result always falls within the height H and the width W.

  Also, in the panorama image generation process, unlike the filter process of the first embodiment, the size of the output image cannot be known from the size of the input image. Therefore, it is not possible to directly obtain an image processing parameter for obtaining an image having a size suitable for the output size of the display unit.

  Therefore, in the present embodiment, the control unit 122 acquires the first output size (the size of the first output image) from the image processing unit 121 as an intermediate result, and based on the size of the first output image, the first output size is obtained. The size of the output image 2 is calculated. Others are the same as in the first embodiment.

  Based on the above, the processing flow of this embodiment will be described using the sequence diagram of FIG.

  First, the control unit 122 acquires the upper limit size from the second terminal device 300 (T201). As in the first embodiment, the output size for the second time is set to the same value as the upper limit size. Then, as described above, the image size (first input size) to be processed for obtaining the first output is set so that the size of the input image is smaller than the height 2 / 3H and the width 2 / 3W. decide. Here, the width and height are set to be 1/4 of the upper limit size. That is, the first input size is set to the width W / 4 and the height H / 4.

  Then, the control unit 122 notifies the image processing unit 121 of the first input size (T202).

  Next, when the first terminal device 200 transmits two images to be combined as image data to the image processing unit 121 (T203), the image processing unit 121 needs the input image to the first input size. Resizing (enlargement or reduction) is performed according to the above, and the synthesis process is performed (T204).

  Thereafter, when the first processing result is transmitted to the second terminal device 300, as shown in FIG. 8A, the second terminal device 300 displays the result (T205). That is, the second terminal apparatus 300 outputs the first processing result in a size that precedes the second processing result and is smaller than the second output size. In this example, the case where the output size of the first time is smaller than the output size of the second time is described. However, in some cases, the output size of the first time is equal to or larger than the output size of the second time. Good.

  Further, the first output size (first output size) is notified to the control unit 122 (T206). Here, the first output size is defined by the size of the circumscribed rectangle of the composite image, and here, for example, it is assumed that the height is H / 3 and the width is W / 3. Further, the control unit 122 determines that an image suitable for the output size of the second terminal device 300 can be combined when the output size of the second output from the first output size is about three times, and outputs the second output. The image size to be processed (second input size) to be obtained is set to three times the first input size. That is, the second input size is estimated to be 3W / 4 width and 3H / 4 height. Since the geometric transformation matrix calculated in the second synthesis process is likely to be different from the first one, the second input size may be multiplied by a scaling factor in consideration of an output size error. For example, the width and height may be multiplied by 0.95.

  Then, the control unit 122 notifies the image processing parameter 121 of the specified second input size to the image processing unit 121 (T207), and the image processing unit 121 converts the input image to the second input size as necessary. Then, the image is resized (enlarged or reduced), and the synthesis process is performed (T208). Note that the geometric transformation matrix used in the first synthesis may be used in the second synthesis process. Alternatively, the geometric transformation matrix may be estimated by newly performing feature point extraction or association with the second input size image. Furthermore, when a new geometric transformation matrix is estimated, there is a high possibility that it is different from the geometric transformation matrix used for the first synthesis, and therefore adjustments such as enlarging / reducing the second input size may be performed.

  Thereafter, when the second processing result is output to the second terminal device 300 (T209), as shown in FIG. 8B, the second terminal device 300 can display a result suitable for the output size.

  As described above, even when the image processing performed by the image processing unit 121 is a panorama image generation process or the like and the output size is not known unless after the image processing, an image of a smaller size (first output image) Based on this, the approximate size of the second output image can be predicted, and the input size can be adjusted to match the display size of the display unit.

  Thus, according to the present embodiment, it is possible to avoid processing / communication of an image having an excessive size with respect to the output size.

5. Third Embodiment A server system 100 according to the third embodiment can be realized by the system configuration shown in FIG. 2 as in the second embodiment.

  Next, the processing flow of this embodiment will be described with reference to the sequence diagram of FIG. First, in T301 to T305 in FIG. 10, the same processing as T201 to T205 in FIG. After the processing from T301 to T305, the first output image as shown in FIG. 9A is displayed on the second display unit 310.

  Next, the image processing unit 121 notifies the control unit 122 of the size (first output size) of the composite image (first output image) that is the first processing result. Then, the control unit 122 determines the size (second output size) of the final output image (second output image), and specifies an image processing parameter that is the determined second output size (T306). .

  Here, if the control unit 122 determines that the difference between the size of the composite image to be finally output and the size of the first composite image is greater than or equal to a predetermined threshold value, the control unit 122 newly adds the second composite image. The size of the image (third output size) is determined, and image processing parameters including the size of the image to be subjected to the second image processing (third input size) are determined. For example, it is assumed that the size of images to be output in order must be within four times the pixel ratio. In this case, for example, image processing parameters including the third input size are determined so that the third output size is 2W / 3 in width and 2H / 3 in height.

  Then, the control unit 122 notifies the image processing parameter 121 including the third input size and the image processing parameter including the second input size to the image processing unit 121 (T307).

  Next, the image processing unit 121 resizes (enlarges or reduces) the input image according to the third input size, performs the second combining process (T308), and outputs the second combining result to the second terminal device 300. Output to. Then, as shown in FIG. 9B, the second terminal apparatus 300 displays the third output image (T309).

  Further, the image processing unit 121 resizes (enlarges or reduces) the input image according to the second input size, performs the third combining process (T310), and outputs the third combining result to the second terminal apparatus 300. Output. Then, as shown in FIG. 9C, the second terminal device 300 displays the second output image (T311).

  In this way, when there is a possibility that the output time will be greatly opened, such as when the size of the first and second output images is different, one or more outputs are performed between the first and second outputs. Image processing parameters can be newly set so as to be obtained. With respect to image processing parameters in which a certain correlation is observed not only with the size but also with the processing time, new parameters can be set so that the output interval does not exceed the threshold value.

  As a result, output can be obtained at regular intervals, and the user's output waiting stress can be alleviated.

6). Techniques of First Embodiment to Third Embodiment The server system 100 according to the first to third embodiments described above performs a reception processing unit that performs a process of receiving information about an input image via the network 500. 110, a processing unit 120 that performs image processing on an input image, and a transmission processing unit 130 that transmits information on an output image after image processing via the network 500. First, the processing unit 120 generates a first output image having a first output size by performing first image processing on the input image. Then, the transmission processing unit 130 performs processing for transmitting information on the first output image via the network 500. Next, the processing unit 120 generates a second output image having a second output size larger than the first output size by performing second image processing on the input image. Then, the transmission processing unit 130 performs processing for transmitting information on the second output image via the network 500.

  That is, before generating the second output image having the second output size, the server system 100 generates the first output image having the first output size smaller than the second output size, and the first output image is generated. Send to terminal device.

  Here, the second image processing may be different from the first image processing or may be the same image processing.

  Accordingly, the user can check the first output image having the first output size smaller than the second output size before the second output image is generated or displayed on the terminal device. In other words, the user can confirm the image processing result at an earlier timing by transmitting the processing result obtained by compressing the information amount in advance.

  Therefore, before obtaining the maximum size output, an image of a smaller size can be confirmed at an earlier timing, and the user can reduce the stress of waiting for the processing result. Further, it can be determined at an early timing whether or not the processing result is in line with the user's intention.

  In addition, the transmission processing unit 130 may perform processing for transmitting information about the second output image after transmitting information about the first output image via the network 500.

  As a result, the user can confirm the first output image before the second output image.

  Also, for example, when it is desired to generate a panoramic image from an image taken on the go, it is desirable that the completion can be confirmed on the spot. This is because, if the subject displayed in the generated panoramic image is not smoothly connected, it is necessary to capture the image that is the original of the panoramic image again on the spot. In this case, it is better if the panoramic image can be immediately confirmed with a portable device on hand. However, if only the finished image is confirmed, the confirmation image does not have to be large in size (high in resolution). That is, the image quality for confirmation is not required to be image quality, but is required to be confirmed immediately on the spot.

  On the other hand, the larger the panorama image finally generated, the better the better the image quality. For this reason, although it takes time to generate an image, there is little need to immediately confirm the finally generated panoramic image as long as the rough image content can be confirmed with the confirmation image. Further, there is no need to check on the spot, and it is only necessary to check with a personal computer at home after returning home.

  Therefore, the transmission processing unit 130 performs processing for transmitting the information of the first output image to the first terminal device 200 having the first display unit 210, and the screen size is larger than that of the first display unit 210. A process of transmitting information of the second output image may be performed on the second terminal device 300 having the second display unit 310 having a large.

  Accordingly, the user can check the first output image on the first terminal device 200, check the second output image on the second terminal device 300, and the like. That is, the first output image that is a thumbnail image for confirmation is transmitted to the first terminal device such as a smartphone, and the user confirms it on the spot, while the second output image that is a high-resolution image. Can be transmitted to a second terminal device such as a personal computer at home so that the user can confirm later.

  In addition, when the difference between the first output size and the second output size is large, a period from when the first output image is transmitted to when the second output image is output may be long. is there. In addition, when the difference between the first output size and the second output size is large, even if the first output image is confirmed, the contents of the second output image cannot be well identified, and the second output size The contents of the output image may not be confirmed.

  Therefore, the processing unit 120 may generate the first output image having the first output size by performing the first image processing on the input image. Then, the transmission processing unit 130 may perform processing for transmitting information on the first output image via the network 500. Next, the processing unit 120 performs third image processing on the input image, thereby generating a third output image having a third output size that is larger than the first output size and smaller than the second output size. May be. Then, the transmission processing unit 130 may perform processing for transmitting information on the third output image via the network 500. Furthermore, the processing unit 120 may generate a second output image having a second output size by performing second image processing on the input image. Then, the transmission processing unit 130 may perform processing for transmitting information on the second output image via the network 500.

  Accordingly, the user can confirm the third output image after confirming the first output image and before confirming the second output image.

  In addition, when the processing unit 120 determines that the difference between the first output size and the second output size is greater than or equal to a predetermined threshold value, the processing unit 120 performs a third image process on the input image, and sets the third output size. A third output image may be generated.

  Thereby, when the difference between the first output size and the second output size is larger than a predetermined threshold, the first output image is transmitted until the second output image is transmitted. The user can check the third output image.

  Therefore, if the size (resolution) of the image is increased in the order of the first output image, the third output image, and the second output image, the user can naturally move the confirmation operation to a larger image. Is possible. Further, before the image of the maximum size (second output image) is displayed, the detailed portion of the image that could not be determined by the small size image (first output image) is changed to an intermediate size image. It is possible to confirm with (third output image).

  In addition, as described above, the first output image is mainly used for confirming the content of the second output image, and therefore needs to be smaller in size than the second output image. Therefore, it is not preferable to determine the second output size without darkness.

  Therefore, the reception processing unit 110 may perform processing for receiving output size specifying information used for specifying the second output size via the network 500. Then, the processing unit 120 may specify second output size information representing the second output size based on the size specifying information, and perform the second image processing based on the second output size information.

  Here, the output size specifying information refers to upper limit size information, which will be described later, or information representing a size ratio between the first output image and the second output image. The output size specifying information may be the input image itself. In this case, the first output size, the second output size, or the like may be calculated from the input image.

  The output size information refers to information representing the number of vertical pixels and the number of horizontal pixels of the output image, for example.

  Accordingly, for example, it is possible to specify the second output size information indicating the second output size that is equal to or smaller than the screen size of the second display unit 310 based on the output size specifying information. Further, for example, the second output size can be made larger than the first output size.

  In addition, the terminal device which transmits output size specific information may be any terminal device among the first terminal device 200 to the third terminal device 400 illustrated in FIG. 1, for example. For example, it is the second terminal device 300 that actually displays the output image, but the screen size and the like of the second terminal device 300 are transmitted from the first terminal device 200 as output size specifying information, etc. Also good.

  For the reasons described above, the first output size does not have to be larger than the screen size of the display unit of the terminal device.

  Therefore, the reception processing unit 110 may perform processing for receiving, as output size specifying information, upper limit size information of an image that can be displayed on the display unit of the terminal device via the network 500. Then, the processing unit 120 may specify the second output size information based on the upper limit size information and perform the second image processing based on the second output size information.

  Here, the upper limit size information is one of the above-described output size specifying information and refers to information indicating the size (upper limit size) of an image that can be displayed on the display unit. The upper limit size is mostly the same as the screen size, but is not limited to this, and may be equal to or larger than the screen size.

  Accordingly, for example, it is possible to specify the second output size information indicating the second output size that is equal to or smaller than the screen size of the second display unit 310 based on the upper limit size information.

  In addition, as described above, the first output image is mainly used for confirming the content of the second output image, and therefore needs to be smaller in size than the second output image. Therefore, it is not preferable to determine the first output size without darkness.

  Accordingly, the reception processing unit 110 may perform processing for receiving output size specifying information used for specifying the first output size via the network 500. Then, the processing unit 120 may specify the first output size information representing the first output size based on the output size specifying information, and perform the first image processing based on the first output size information.

  For example, the reception processing unit 110 may perform processing for receiving upper limit size information as output size specifying information.

  Accordingly, for example, it is possible to specify the first output size information representing the first output size that is equal to or smaller than the screen size of the first display unit 210 based on the output size specifying information. Therefore, for example, the first output image can be generated as a thumbnail image representing the content of the second output image.

  Further, at least one of the first output image and the second output image may be an image having the same size as the screen size of the first terminal device or the second terminal device.

  Therefore, the reception processing unit 110 may perform a process of receiving the first screen size information of the first display unit 210 of the first terminal device 200 via the network 500. Then, the processing unit 120 may perform the first image processing based on the first output size information.

  As a result, for example, the first output size can be matched with the screen size of the first display unit.

  In addition, the reception processing unit 110 may perform processing for receiving the second screen size information of the second display unit 310 of the second terminal device 300 via the network 500. Then, the processing unit 120 may perform the second image processing based on the second output size information.

  Thereby, for example, the second output size can be matched with the screen size of the second display unit.

  That is, the control unit 122 acquires screen size information of the first display unit 210 or the second display unit 310. Then, the server system 100 transmits an output image having the same size as the screen size to any one of the terminal devices at least once out of transmitting the image a plurality of times. As a result, the user can check an image optimized for the size of the display unit at least once.

  The image processing performed by the image processing unit 121 is panorama image generation processing or the like, and the second output size may not be known unless after image processing.

  Therefore, the processing unit 120 may generate the first output image by performing the first image processing. Next, the transmission processing unit 130 may perform processing for transmitting information on the first output image via the network 500. Furthermore, the processing unit 120 specifies second output size information representing the second output size based on the first output size information, and performs second image processing based on the second output size information. A second output image may be generated. Then, the transmission processing unit 130 may perform processing for transmitting information on the second output image via the network 500.

  Thereby, for example, even when the image processing performed by the image processing unit 121 is a panorama image generation process or the like and the output size is not known unless after the image processing, an image with a smaller size (first output image) ) To predict the approximate size of the second output image, and adjust the input size to match the display size of the display unit.

  Therefore, it is possible to avoid processing or communicating an image having an excessive size with respect to the output size.

  In addition, the processing unit 120 performs a first scaling process on the input image, generates a first output image, and performs a second scaling process with a smaller scaling rate than the first scaling process on the input image. To generate a second output image.

  Here, the first scaling process and the second scaling process may be an enlargement process or a reduction process.

  This makes it possible to generate images of different sizes from the same input image and perform image processing based on the generated images.

  Also, the larger the image size (resolution), the larger the image data size, and the longer the time for transmitting the image from the terminal device to the server system. However, the thumbnail image used for confirmation as described above does not need to have a large size (resolution), and the image itself that is the source of the thumbnail image does not need to have a large size.

  Therefore, another input image (first input image) used to generate a thumbnail image (first output image) is first transmitted to the server system 100 to output a high-resolution output image (second output). A method of transmitting an input image (second input image) used for generating (image) later is conceivable. However, the first input image is, for example, an image obtained by scaling the second input image by the terminal device (enlargement process or reduction process), and the contents shown in the first input image and the second input image are the same. Need to be. This is because the first output image generated from the first input image is for confirmation of the second output image.

  That is, the reception processing unit 110 may perform a process of receiving, as input images, a first input image having a first input size and a second input image having a second input size larger than the first input size. Good. Next, the processing unit 120 may generate a first output image having a first output size by performing first image processing on the first input image. Then, the transmission processing unit 130 may perform processing for transmitting information on the first output image via the network 500. Further, the processing unit 120 may generate a second output image having a second output size by performing second image processing on the second input image. Then, the transmission processing unit 130 may perform processing for transmitting information on the second output image via the network 500.

  Thereby, it is possible to solve the problem that the transmission time of the input image becomes long and the time until the user confirms the first output image becomes long. That is, without waiting for the completion of the process of receiving the information of the second input image, the process of receiving the information of the first input image is completed, and the first image process is started for the first input image. Etc., and the first output image can be presented to the user at an earlier timing. Therefore, for example, it is possible to perform the first image processing on the first input image while transmitting / receiving the information of the second input image.

  The reception processing unit 110 may perform a process of receiving the first input image having the first input size and the second input image having the second input size. Next, the processing unit 120 may perform a first scaling process on the first input image to generate a first output image having a first output size. Then, the transmission processing unit 130 may perform processing for transmitting information on the first output image via the network 500. Next, the processing unit 120 may perform a second scaling process having the same scaling rate as the first scaling process on the second input image to generate a second output image having the second output size. . Then, the transmission processing unit 130 may perform processing for transmitting information on the second output image via the network 500.

  This makes it possible to perform scaling processing on the two types of images having different sizes at the same scaling rate. In this case, even if the scaling rate is the same, the size of the original input image is different, so that it is possible to obtain output images of different sizes.

  In addition, the transmission processing unit 130 may perform processing for transmitting information on the first output image via the network 500. Then, the reception processing unit 110 may perform a process of receiving presence / absence information of the user's approval for the first output image via the network 500. Furthermore, when the presence / absence information received by the reception processing unit 110 indicates that the user has approval, the processing unit 120 may start the second image processing and generate a second output image. . Then, the transmission processing unit 130 may perform processing for transmitting information on the second output image via the network 500.

  Thereby, for example, the user can check the first output image, determine whether to start the second image processing according to the current image processing parameter, and send an instruction to the server system. Become.

  In addition, the transmission processing unit 130 may perform processing for transmitting information on the first output image via the network 500. Then, the reception processing unit 110 may perform a process of receiving presence / absence information of the user's approval for the first output image via the network 500. Further, the processing unit 120 may stop or interrupt the second image processing when the presence / absence information received by the reception processing unit 110 indicates that there is no user approval. On the other hand, when the presence / absence information received by the reception processing unit 110 indicates that the user has approval, the processing unit 120 continues the second image processing, generates a second output image, and transmits it. The processing unit 130 may perform processing for transmitting information on the second output image via the network 500.

  As a result, for example, the user can confirm the first output image, determine whether or not to stop or interrupt the current second image processing, and send an instruction to the server system. Become.

  In addition, the transmission processing unit 130 may perform processing for transmitting information on the first output image via the network 500. Then, the reception processing unit 110 may perform a process of receiving presence / absence information of the user's approval for the first output image via the network 500. Furthermore, when the presence / absence information received by the reception processing unit 110 indicates that the user has approval, the transmission processing unit 130 performs processing for transmitting the information of the second output image via the network 500. Also good.

  Accordingly, for example, the user can confirm the first output image, determine whether or not to transmit the generated second output image to the terminal device, and transmit an instruction to the server system.

  The processing unit 120 may perform a panoramic image generation process as the first image process and the second image process.

  This makes it possible to generate panoramic images as the first output image and the second output image.

  The processing unit 120 performs a first image process to generate a first output image, and a second process to perform a second image process and generate a second output image. And may have a part. Then, the second processing unit may perform the second image processing in parallel while the first processing unit performs the first image processing. Further, the transmission processing unit 130 may perform processing for transmitting information on the first output image via the network 500 and transmitting information on the second output image after transmitting the information on the first output image. .

  As a result, the processing becomes efficient, and the user can check each output image at an earlier timing.

  The server system or the like according to the first to third embodiments may realize part or most of the processing by a program. In this case, a server system or the like according to the first to third embodiments is realized by a processor such as a CPU executing a program. Specifically, a program stored in the information storage medium is read, and a processor such as a CPU executes the read program. Here, the information storage medium (computer-readable medium) stores programs, data, and the like, and functions as an optical disk (DVD, CD, etc.), HDD (hard disk drive), or memory (card type). It can be realized by memory, ROM, etc. A processor such as a CPU performs various processes of the first to third embodiments based on a program (data) stored in the information storage medium.
