1. Overview In recent years, with the development of Internet technology, all processing is not performed within a single information terminal, but a part of the processing is performed by an external server device (server system) via the network. There has been an increase in the use form of computers that receive the processing results via the Internet. Such a utilization form is called so-called cloud computing.

  As an example of such a technique, for example, an image is captured by an information terminal device such as a camera-equipped mobile phone, and image processing is performed on the captured image by an external server device or the like via a network. There is a technique for receiving an image of a processing result.

  Here, a user who frequently performs image processing often pays attention to the length of the waiting time until the image processing result is presented after the user gives an instruction to start image processing.

  In this regard, in the image processing system as described above, the processing speed is increased by placing a part of the processing on a server device or the like having a higher processing capacity than the information terminal device, thereby reducing the image processing time. Shorten.

  However, on the other hand, a communication waiting time is newly generated while the information terminal device and the server device communicate with each other via the network. If the communication waiting time is long, even if the image processing time can be shortened, the total waiting time of the user is not shortened.

  That is, in the image processing system as described above, in order to shorten the total waiting time, it is necessary not only to shorten the image processing time but also to shorten the communication waiting time. Further, the user tends to be particularly concerned about the waiting time until the processing result is presented for the first time after starting the image processing.

  Therefore, in the server systems and the like according to the first to fourth embodiments, which will be described in detail later, the waiting time until the image processing result is presented to the user for the first time after the image processing is started is shortened.

  Here, the outline of the invention disclosed in Patent Document 1 will be briefly described. In the invention disclosed in Patent Document 1, the server device first transmits a so-called preview image having a small data size to the information terminal device, and then transmits a result image having a data size larger than the preview image.

  Specifically, first, the information terminal device (terminal, image display device) selects (designates) a reduced image to be subjected to the tone conversion process from among a plurality of reduced images of the original image (main image), and selects the selected image. The reduced image thus transmitted is transmitted to a server device (server). Further, the information terminal device selects (specifies) the type of image tone and transmits it to the server device.

  On the other hand, the server device performs a tone conversion process on the selected reduced image with the selected type of image tone, and transmits the image tone conversion process result to the information terminal device. Note that the tone conversion processing result (hereinafter referred to as the first result image) transmitted here is an image having the same size as the reduced image, and corresponds to the preview image described above.

  Then, after receiving the first result image and displaying the first result image on the display unit, the information terminal device designates the original image of the reduced image to be processed, Information is transmitted to the server device.

  On the other hand, the server device performs the same tone conversion processing as that performed on the reduced image for the designated original image, and transmits the processing result to the information terminal device. Then, the information terminal device displays a processing result image (hereinafter referred to as a second result image) on the display unit. The above is the outline of the invention disclosed in Patent Document 1.

  Thus, since the preview image (first result image) can be presented to the user earlier than the second result image having the same size as the original image, the invention disclosed in Patent Document 1 is disclosed. However, compared with the technique of always performing image processing on the original image, the waiting time (hereinafter referred to as the first waiting time) until the image processing result is presented to the user for the first time after starting the image processing is shortened. can do.

  However, the technique disclosed in Patent Document 1 does not consider the communication state of the network or the state of the image processing unit. That is, when there is a lot of noise and the communication state of the network is bad, the communication waiting time is long, and when the processing load on the image processing unit is large, the processing time of the image processing may be long. Of course, in this case, the first waiting time becomes longer.

  That is, in the method disclosed in Patent Document 1, the first waiting time may not be shortened depending on the communication state of the network, the state of the image processing unit, and the like.

  Furthermore, in some cases, the waiting time from when the information terminal device receives the first result image until it receives the second result image (hereinafter referred to as the second waiting time) is the first waiting time. It may be very long compared to. For example, the second waiting time is 10 times the first waiting time. While it is important to shorten the first waiting time, it is also important to shorten the second waiting time.

  Therefore, the server system according to the first embodiment, which will be described later, determines the number of output of the result image according to the communication state of the network, and determines the image processing parameter based on the number of output. For example, when the communication state of the network is good and the communication speed is high, the number of outputs is set to one, and the result image obtained by performing image processing on the original image is transmitted from the beginning. On the other hand, for example, when the communication state of the network is poor and the communication speed is slow, the number of outputs is set to 3, and the data size of the result image transmitted for the first time is reduced to shorten the communication time. Then, as the number of times of image processing increases, the second time and the third time, the data size of the transmitted result image is increased. Thereby, regardless of the communication state of the network and the state of the image processing unit, it is possible to reduce the waiting time until the image processing result is presented to the user for the first time after starting the image processing.

  In addition, the server system or the like according to the second embodiment described later sets an output limit time together with the output count based on a user input, and determines an image processing parameter based on the output count and the output limit time. Thereby, it becomes possible to transmit each result image by the set output restriction time. Therefore, for example, it is possible to prevent the second waiting time described above from becoming much longer than the first waiting time.

  Furthermore, in a third embodiment to be described later, an upper limit value of the transmission data size is determined based on the communication speed, and when the communication speed changes, an image to be transmitted is added or deleted.

  In the fourth embodiment to be described later, the communication time and the image processing time are determined based on the output time limit, and the image processing parameter is determined from both the determined communication time and the image processing time. .

Furthermore, in the image processing of the present embodiment, in addition to the image tone conversion processing, resizing processing as described later may be performed together. For example, the first image processing or the second image in FIG. In the process, the original image PIM is reduced. However, the types of image processing are not limited to these, and other image processing contents may be selected.

  Here, as described above, the time until the information terminal device TU receives the image processing result and presents it to the user varies depending on the communication state (communication environment), the processing load applied to the image processing unit 140, and the like. . For example, when the communication state is poor and the communication speed is low, or when the processing load applied to the image processing unit 140 is large, the timing of presenting the result image to the user for the first time after starting the image processing is delayed.

  On the other hand, in many cases, the user only needs to be able to confirm the outline of the result image at the initial stage, and may not necessarily be able to confirm the complete result image from the beginning.

  Therefore, in this embodiment, even when the communication state is bad or the processing load on the image processing unit 140 is large, the image processing result is displayed a predetermined number of times in order to present the result image to the user at an earlier timing. And present it to the user step by step. In other words, in the present embodiment, the result image is presented to the user by a predetermined timing regardless of whether the communication state is good or bad and the processing load on the image processing unit 140 is large. To present.

  In the example of FIG. 4, the number of output of the result image is set to 3 based on the system information such as the communication state and the processing load. A method for determining the number of outputs will be described later with reference to FIGS. 5 (A) and 5 (B).

  Then, the server system SV performs the first image processing IMP1 on the processing target image (original image) PIM, generates the first result image OIM1, and sends the first result image OIM1 to the information terminal device TU. Send. As described above, in the first image processing IMP1, the processing target image PIM is reduced before the image tone conversion processing, and the image tone conversion processing is performed on the generated reduced image. In this image processing, the smaller the image size, the shorter the processing time. Furthermore, if the size of the result image is small, the data size is also small, so that the transmission time to the information terminal device TU can be short. That is, the image processing time and the communication time can be shortened.

  Accordingly, even when the final image processing result for the processing target image PIM cannot be transmitted to the user by a predetermined time because the communication state is poor, the first result image OIM1 is displayed as a preview image to the user. It can be presented first. As a result, it is possible to meet the user's need to quickly check the summary of the processing result.

  Then, in the same procedure, the second image processing IMP2 is performed to generate a second result image OIM2 having a size larger than the first result image OIM1 and smaller than the original image PIM, and this is generated as the information terminal device TU. Send to. Also in this case, after the reduction process is performed on the processing target image PIM, the image tone conversion process is performed.

  Further, the third image processing IMP3 is performed, a third result image OIM3 having the same size as the processing target image PIM is generated, and transmitted to the information terminal device TU. At this time, the reduction process is not performed.

  Accordingly, the first result image OIM1 and the second result image OIM2 can be presented to the user first, and the third result image OIM3 that is the final processing result can also be presented to the user.

  Here, the relationship between the number of outputs and the system information (communication speed) in this embodiment is shown in FIG. For example, the output count determination unit 160 determines the output count based on these pieces of information. Specifically, when the communication speed is faster than S2 (for example, 10 Mbps, Wi-Fi, etc.), the final output result can be received immediately, so there is no need to bother to send a plurality of result images. For this reason, the number of outputs is one. When the number of outputs is one, only the final result needs to be transmitted. For example, a Quad-VGA (1280 × 960) image is output.

  On the other hand, when the communication speed is S1 (for example, 500 kbps, 3G, etc.) or less, since it takes time to confirm the final output result, the number of outputs is determined to be three as described with reference to FIG. To do.

  If the communication speed is greater than S1 and less than or equal to S2, the number of outputs is set to two. When the number of times of output is two times or more, for example, the original image is reduced, and the first output result is QVGA (320 × 240), the second is VGA (640 × 480), and the like. On the other hand, the image processing parameters relating to the input image are adjusted so that the vertical and horizontal sizes become a geometric series with a coefficient of 0.5.

  Further, when the number of times of output is two or more, the image processing is not limited to the reduction processing, and processing for adjusting DPI may be performed. When adjusting the DPI, it is more preferable to acquire information on the size and resolution (DPI) of the display panel from the terminal and adjust the output so that it is a multiple thereof. For example, if the resolution of the display panel of the terminal is 200 dpi, the image parameter is adjusted so that the first image is 50 dpi and the second image is equivalent to 100 dpi.

  Further, in the image processing, processing for adjusting the compression rate may be performed. For example, if the output image format is JPEG, the compression rate is set to 50%, 75%, and 100%.

  In the image processing, a process for cutting out a partial image may be performed. For example, the partial area may be cut out so that the output image area is 1/16, 1/4, or 1/1 with respect to the original image, and the image processing may be performed on the cut out image. It should be noted that these reduction processing, DPI adjustment processing, image compression processing, partial region clipping processing, etc. are not necessarily performed by any one processing, and may be performed by combining several processing. Good.

  Next, FIG. 5B shows another relationship between the number of outputs and system information (communication speed). When it is desired to reduce the occupancy time of a certain user's line, the lower the communication speed, the smaller the number of outputs. That is, contrary to the previous case, when the communication speed is S1 or less, the time for occupying the line becomes longer, so the number of outputs is set to one. On the other hand, when the communication speed is higher than S2, the time for occupying the line becomes relatively short, so that three outputs are allowed.

  In addition, the number of outputs may be determined based not only on the communication speed but also on a wired or wireless line, a public line or a private line. These are also information representing the network status (communication status).

  As a modification, the image processing parameter may be determined so that the output interval becomes a predetermined interval. For example, the size of the transmitted result image is adjusted so that the time interval between the second output and the third output is twice the time interval between the first output and the second output. For example, the third output size is set to be twice as large as the second output size in terms of the number of pixels.

  Next, FIG. 6 shows a processing sequence diagram when the number of outputs is three.

  First, the system information acquisition unit 120 acquires the communication speed between the server system 100 and the information terminal device 200 from the transmission processing unit 150 as system information (T101). Here, it is assumed that the communication speed is equal to or lower than S1 in FIG.

  Next, the image acquisition unit 110 acquires a processing target image (T102).

  Then, the image acquisition unit 110 transmits the acquired processing target image and information about the image such as the image size to the image processing unit 140 (T103). Note that the information related to the image may be transmitted as part of the data of the processing target image in the form of, for example, a header of an image file format.

  Further, the system information acquisition unit 120 acquires system information from the image processing unit 140 (T104), and transmits the acquired system information (communication speed, etc.) to the output count determination unit 160 (T105).

  Next, the output frequency determination unit 160 outputs the output frequency based on the relationship between the output frequency and the system information (communication speed) shown in FIG. 5A and the acquired communication speed (S1 or less). Is determined three times (T106), and the number of outputs is transmitted to the parameter determination unit 130 (T107).

  Further, the parameter determination unit 130 acquires system information such as the above-described information about the image, information about the image processing, and information about the processing capability from the system information acquisition unit 120 (T108). For example, information relating to image processing includes information relating to the relationship between the output size and the input size, information relating to the relationship between the input size and the processing load, and the like. Further, for example, as information regarding the processing capability, the hardware specification of the image processing unit 140 can be acquired. In this example, information on the processing load and processing capacity is not acquired, and the relationship that the output size is equal to the input size is acquired as information. Note that the above-described system information includes information related to image processing and information related to the processing capability of the image processing unit 140.

  Then, the parameter determination unit 130 determines an image processing parameter for obtaining each output image based on the information regarding the image processing acquired at T108 and the number of outputs acquired at T107 (T109). In this example, since the output size is the same as the input size, here, the reduction ratio for the input original image is also determined as an image processing parameter. For example, the reduction ratio is determined so that the original image is 1/1 times, 1/2 times, and 1/4 times in length and width.

  Further, the parameter determination unit 130 may determine a parameter other than the reduction ratio as the image processing parameter. For example, in the case of edge smoothing processing in which a pixel value targeted for image processing is obtained by weighted averaging of adjacent pixel values, the number of adjacent pixels may be determined as an image processing parameter. For example, the number of adjacent pixels is 2 for an image having a size of 1/4 in the vertical and horizontal directions, 4 for an image having a size of 1/2, and for an image having the same size as the original image Will be decided.

  Next, the parameter determination unit 130 transmits the determined image processing parameter to the image processing unit 140 (T110).

  Then, the image processing unit 140 performs image processing on the processing target image acquired from the image acquisition unit 110 based on the image processing parameter acquired from the parameter determination unit 130 (T111), and transmits the result image to the transmission processing unit 150. (T112).

  Further, the transmission processing unit 150 transmits the result image to the reception processing unit 210 of the information terminal device 200 via the network 500 (T113). The information terminal device 200 performs an appropriate process according to the application such as displaying or saving the result image (T114).

  Then, similarly to T111 to T114, the second image processing and output are performed (T115), and then the third image processing and output are performed (T116).

3.3. Method Next, the method of the present embodiment will be described.

  The server system 100 according to the present embodiment described above includes an image acquisition unit 110 that acquires a processing target image for image processing, a system information acquisition unit 120 that acquires system information, a parameter determination unit 130 that determines image processing parameters, An image processing unit 140 that performs image processing and generates a result image, and a transmission processing unit 150 that performs processing for transmitting information on the result image to the information terminal device 200 via the network 500 are included. First, the system information acquisition unit 120 acquires information including at least one of information indicating the state of the network 500 and information indicating the state of the image processing unit 140 as system information. Further, the parameter determination unit 130 determines an image processing parameter based on the system information. Then, the image processing unit 140 performs image processing on the processing target image according to the determined image processing parameter, and generates a result image.

  That is, the server system 100 according to the present embodiment acquires a processing target image for image processing, and obtains information including at least one of information indicating the state of the network 500 and information indicating the state of the image processing unit 140 as system information. Get as. The server system 100 determines image processing parameters based on the acquired system information, performs image processing on the processing target image according to the determined image processing parameters, and generates a result image. Further, the server system 100 transmits the result image information to the information terminal device 200 via the network 500.

  On the other hand, the information terminal device 200 receives information on the result image.

  Here, the processing target image refers to an image that is a direct target of image processing. In other words, the processing target image is an image input to the image processing.

  The system information is information including at least one of information representing the state of the network 500 and information representing the state of the image processing unit 140. A specific example of information indicating the state of the network 500 and information indicating the state of the image processing unit 140 will be described later.

  Furthermore, the image processing parameter is a parameter used in image processing. Specifically, it indicates the luminance value and pixel value of the image after the change of the image tone, information indicating the type of image processing content, and the line thickness after the change of the image tone when the image is changed to an illustration tone. Furthermore, the resizing rate, compression rate, cutout range, cutout condition, and the like of the processing target image are included in the image processing parameters.

  Image processing refers to, for example, image tone conversion processing. However, the image processing includes pre-processing such as resizing processing on the processing target image and post-processing such as compression processing on the image obtained after the image tone conversion processing.

  The result image refers to an image generated as a result of image processing. Further, the result image information may be the result image itself, or other information such as link information (URL or the like) to an external server in which the result image is stored.

  Accordingly, it is possible to reduce the waiting time until the image processing result is presented to the user for the first time after starting the image processing regardless of the network communication state or the state of the image processing unit. For example, the processing result can be acquired in a certain processing time without being influenced by the state of the server system 100 or the network state.

  Further, when determining image processing parameters based on system information, first, the number of output of a result image may be obtained based on system information, and each image processing parameter may be determined based on the number of outputs.

  That is, the server system 100 of the present embodiment may include an output number determination unit 160 that determines the number of output times of the result image based on the system information. At this time, the parameter determination unit 130 determines the first image processing parameter to the Nth image processing parameter based on the system information when the determined number of outputs is N times (N is an integer of 2 or more). May be. The image processing unit 140 performs image processing on the processing target image according to the first image processing parameter to the Nth image processing parameter, and generates the first result image to the Nth result image. Good. Further, the transmission processing unit 150 may transmit information on the first result image to the Nth result image to the information terminal device 200.

  That is, the number of outputs is determined based on the system state, and image processing parameters for each output are determined.

  Here, the output count refers to the number of result images that the server system 100 transmits to the information terminal device 200. Note that the number of outputs does not necessarily match the number of transmissions of the transmission processing unit 150. This is because the reception processing unit 210 of the information terminal device 200 may fail in the reception processing, and the transmission processing unit 150 may retransmit the same result image.

  The first image processing parameter is an image processing parameter used for generating the first result image. For example, in the example of FIG. 4, it indicates an image processing parameter used in the first image processing IMP 1. The same applies to the second image processing parameter to the Nth image processing parameter.

  Furthermore, the first result image refers to an image generated by performing image processing according to the first image processing parameter. For example, in the example of FIG. 4, the image OIM1 corresponds to the first result image. The same applies to the second result image to the Nth result image.

  This makes it possible to present the image processing result to the user as soon as possible according to the system state. In addition, the server system 100 can adjust the line occupancy.

  When the number of outputs determined by the output number determination unit 160 is 1, the parameter determination unit 130 may determine the first image processing parameter based on the system information. Then, the image processing unit 140 may perform image processing on the processing target image according to the first image processing parameter and generate a first result image. Further, the transmission processing unit 150 may transmit information of the first result image to the information terminal device 200.

  That is, as described with reference to FIG. 5A, when the communication speed is larger than the predetermined reference value, the final output result can be received immediately. As described with reference to FIG. 5B, when the communication speed is smaller than the predetermined reference value, a certain user occupies the line for a long time, so that the time for occupying the line is shortened. It is possible to reduce the number of outputs to one.

  As shown in FIG. 5A, when the number of times of output is two or more, the result image with a smaller data size may be transmitted to the information terminal device 200 in order.

  That is, the image processing unit 140 performs image processing according to the i-th image processing parameter, generates an i-th result image, performs image processing according to the k-th image processing parameter, and has a data size larger than that of the i-th result image. A k-th result image having a large value may be generated. Note that i and k are integers satisfying 1 ≦ i <k ≦ N. Then, the transmission processing unit 150 may transmit the information of the kth result image to the information terminal device 200 after transmitting the information of the i th result image to the information terminal device 200.

  Thereby, for example, when the communication speed is low, it is possible to present a small-sized result image to the user as a preview image first. As a result, even when the communication speed is low, the user can check the image processing result faster.

  Here, the information indicating the state of the network 500 described above may be transfer rate information indicating the transfer rate of the network 500.

  In this case, the system information acquisition unit 120 may acquire transfer rate information indicating the transfer rate of the network 500 as the system information. Then, the parameter determination unit 130 may determine the data size of the result image to be generated based on the transfer rate information and specify the image processing parameter corresponding to the determined data size.

  Here, it is assumed that the transfer rate information includes, for example, information indicating a theoretical value or effective value of a communication rate in a predetermined communication standard, a past average communication rate, or the like.

  As a result, the server system 100 can control the communication time with the information terminal device 200, and the like.

  In addition, images in the present embodiment and other embodiments described later include not only still images but also moving images. That is, the original image, the first result image, the second result image, and the like may be moving images. Hereinafter, these moving images are referred to as an original moving image, a first result moving image, and a second result moving image, respectively.

  A specific example will be described below with reference to FIG. For example, when the original moving image is a moving image for 2 hours of full HD (Full High Definition: 1920 × 1080) and 30 fps (frame per second), in the first image processing, from the timing T0 in FIG. Only the first 10 seconds of the time interval up to the timing T1 is extracted to generate a 480 × 270 size 15 fps moving image, and a tone conversion process is performed on the generated moving image, and the first result moving image An image is generated and transmitted to the information terminal device 200.

  In the second image processing and the third image processing, the size and fps of the extracted image are made larger than those in the first image processing.

  According to this, it is possible to significantly reduce the amount of processing compared to the case where image processing is performed on all frames at the original size. Specifically, if the same processing amount is required for each pixel, the first image processing described above is (10 sec / (120 × 60) compared to the case where image processing is performed for all frames at the original size. sec) × (15 frame / 30 frame) × (480/1920) × (270/1080) = 1/23040 can be compressed.

4). Second Embodiment 4.1. System Configuration Example FIG. 7 shows a system configuration example according to this embodiment. The configuration example of FIG. 7 is different from the configuration example of FIG. 3 in that the number of outputs and the output time limit can be determined by the user.

  Therefore, in this embodiment, the information interface device 200 is further provided with a user interface unit 230, and the server system 100 is further provided with a reception processing unit 170.

  The user interface unit 230 of the information terminal device 200 acquires input information from the user. The user interface unit 230 may be an operation unit. In this case, the user interface unit 230 may be configured by, for example, a keyboard, a mouse, a touch panel, or the like. Further, the user interface unit 230 may have a function of a transmission processing unit that performs wireless or wired communication.

  On the other hand, the reception processing unit 170 of the server system 100 receives user input information (user request) from the user interface unit 230 via the network 500. The user input information is information indicating, for example, the number of times of output and output limit time. Then, the reception processing unit 170 notifies the output number determination unit 160 of the received output number, and notifies the parameter determination unit 130 of information about the output time limit. Although not shown in FIG. 7, the server system 100 may have an antenna unit, and the reception processing unit 170 controls the antenna unit, and the antenna unit performs wireless communication with the information terminal device 200 and the like. You may go.

4.2. Details of Processing In this embodiment, the user sets the number of outputs within 3 times via the user interface unit 230. Also, the output limit time is limited to within 30 seconds from the start of processing for the first output timing, within one minute after completing the transmission of the first result image for the second time, and limited for the third and subsequent times. Set to None. In the following, it is assumed that the processing in the image processing unit 140 is completed in a few seconds, and is not considered here as the time required for obtaining the result. The size of the highest quality result image is 5 MB.

  Here, the flow of the image processing parameter determination process performed by the parameter determination unit 130 of the present embodiment will be described using the flowchart of FIG.

  First, the size of the highest quality result image is acquired (S201), then the communication speed (S202), and the output time limit is acquired (S203).

  Next, it is determined whether or not the transmission of the highest quality result image can be completed within the first output limit time (S204).

  If it is determined that transmission of the highest quality result image can be completed within the first output limit time, the final output image processing parameters that do not compress the data amount are set so that the first output is the final output. Then, the image processing parameter determination process ends (S205).

  For example, in an environment where the communication speed is 40 Mbps (= 5 MB / sec), transmission of the maximum size image can be completed in one second. Therefore, in this case, the output count determination unit 160 sets the output count to one.

  On the other hand, if it is determined in step S204 that transmission of the highest quality result image cannot be completed within the first output limit time, first, image processing parameters that compress the data amount of the first output are determined (S206). ). Then, it is determined whether or not the transmission of the highest quality result image can be completed within the second output time limit (S207).

  If it is determined that transmission of the highest quality result image is possible within the second output time limit, the second output is the final output, so the image processing parameters for final output without compressing the data amount are set. Then, the image processing parameter determination process is completed (S205).

  On the other hand, if it is determined in step S207 that the transmission of the highest quality result image cannot be completed within the second output time limit, image processing parameters for compressing the second output data amount are determined (S208). ). Then, in order to set the third output as the final output, an image processing parameter for final output that does not compress the data amount is further set, and the image processing parameter determination processing ends (S205).

  For example, in an environment where the communication speed is 400 Kbps (= 50 KB / sec = 0.05 MB / sec), transmission of the result image requires 100 seconds, and thus transmission cannot be completed within the first output limit time. Therefore, the data size of the result image is adjusted so that the result image can be transmitted within 30 seconds with the first output. For example, image processing parameters for performing reduction processing, DPI reduction processing, clipping processing, compression processing, or the like are determined on the highest quality result image. Alternatively, as described in the first embodiment, image processing parameters used for adjusting the data size of the input image may be set as preprocessing. For example, the image size is determined so as to be reduced to 500 KB. Furthermore, when 100 seconds are required for transmitting the result image, the second output limit time is also exceeded. Similarly, the image processing parameters for the second time are set so that the transmission can be completed within one minute. decide. Finally, an image processing parameter for the third time that does not compress the output image is determined.

4.3. Method Next, the method of the present embodiment will be described.

  The server system 100 according to the present embodiment may include a reception processing unit 170 that receives information indicating the number of output times of the result image from the information terminal device 200. The parameter determining unit 130 determines the first image processing parameter to the Nth image processing parameter based on the system information when the received output count is N times (N is an integer equal to or greater than 2). May be. Furthermore, the image processing unit 140 performs image processing on the processing target image according to the first image processing parameter to the Nth image processing parameter, and generates the first result image to the Nth result image. Good. Then, the transmission processing unit 150 may transmit information on the first result image to the Nth result image to the information terminal device 200.

  As a result, the user can confirm the result image of the image processing as many times as specified by the user.

  In addition, even when the result image is transmitted the determined number of times of output, in some cases, the waiting time (hereinafter, referred to as the second result image) from when the information terminal device 200 receives the first result image is received. (Referred to as the second waiting time) may be much longer than the first waiting time. For example, the second waiting time may be ten times the first waiting time. In such a case, even if the first waiting time is short, the user may feel dissatisfied because the waiting time is long.

  On the other hand, if the user has confirmed the first result image, the user does not necessarily want to confirm the second result image as soon as possible. That is, since the rough content of the image processing result has been confirmed by the first result image, for example, for the second result image having a higher resolution, it is only necessary to confirm the image processing result by a predetermined time. In some cases. In this case, there is no problem even if the processing time and communication time of the second image processing are long. Specifically, it is assumed that the first result image is confirmed when going out, and the second result image is confirmed after returning home.

  Therefore, the parameter determination unit 130 acquires output limit time information indicating the output limit time for transmission of the information of the result image to the information terminal device 200, and determines an image processing parameter based on the acquired output limit time information. May be. Then, the image processing unit 140 may perform image processing on the processing target image according to the image processing parameter. Further, the transmission processing unit 150 may transmit the information of the result image to the information terminal device 200 at least by the output restriction time.

  That is, the parameter determination unit 130 determines the image processing parameter so that the image processing unit 140 can complete the image processing by the acquired output restriction time.

  Here, the output restriction time refers to a time at which the transmission processing unit 150 must transmit a result image to the information terminal device 200 at least by that time. However, since the transmission / reception process may fail, the information terminal device 200 may not be able to receive the result image before the output restriction time.

  The output restriction time information refers to information representing the output restriction time. For example, the output limit time information may be an actual output limit time, or information indicating a time from the current time to the output limit time.

  Accordingly, the server system 100 can transmit each result image by the set output limit time. Therefore, for example, it is possible to prevent the second waiting time described above from becoming much longer than the first waiting time. On the other hand, the user can confirm the result image by the designated time.

  In addition, the server system 100 according to the present embodiment may include a reception processing unit 170 that receives the output restriction time information from the information terminal device 200.

  As a result, the user can transmit the result image to the server system 100 by the time designated by the user.

  Further, the result image may be transmitted so that the transmission time interval of the result image becomes a predetermined interval.

  That is, the parameter determination unit 130 sets the time interval between the first output timing for outputting the first result image and the second output timing for outputting the second result image to be a predetermined interval. One image processing parameter and a second image processing parameter may be determined. Then, the image processing unit 140 performs image processing on the processing target image according to the first image processing parameter, generates a first result image, and performs image processing on the processing target image according to the second image processing parameter. To generate a second result image. Further, the transmission processing unit 150 transmits information about the first result image to the information terminal device 200 at the first output timing, and transmits information about the second result image at the second output timing. Also good.

  As a result, it is possible to transmit a result image at a preset time interval. Further, as in the case of designating the output time limit, it is possible to prevent the second waiting time described above from becoming much longer than the first waiting time, and the like. It is possible to confirm the result image by the time.

5. Third Embodiment 5.1. System Configuration Example The system configuration of this embodiment is the same as the system configuration of the first embodiment shown in FIG.

5.2. Details of Processing In the present embodiment, the upper limit value of the transmission data size is determined based on the communication speed, and when the communication speed changes due to the movement of the user, the number of result images to be transmitted is determined. Process to change (add or reduce).

  Here, FIG. 9 shows an example of a state in which the communication speed has changed because the user has moved between network environments having different communication speeds. In FIG. 9, it is assumed that the access point AP1 is a 3G line access point, and the access point AP2 is a WiFi line access point. Further, the communicable range of the access point AP1 is an area in the AR1, and the communicable range of the access point AP2 is an area in the AR2.

  In this example, the user 10 with the information terminal device 200 is at the point P1, communicates with the server system 100 via the access point AP1, and causes the server system 100 to execute image processing. Then, it is assumed that the user 10 moves from P1 to a point P2 at a certain timing. A processing sequence diagram of the server system 100 at this time is shown in FIG. The rough processing flow from T301 to T314 in FIG. 10 is the same as the processing flow from T101 to T114 described with reference to FIG.

  First, the system information acquisition unit 120 determines the communication speed between the server system 100 and the information terminal device 200 for a network that is frequently used among the networks that the user has accessed so far, based on the user's system usage history information. Information is acquired from the transmission processing unit 150 (T301). Here, it is assumed that two types of communication speeds regarding the 3G line and the WiFi line are acquired.

  The system information acquisition unit 120 may store the communication speed for each communication standard as system information in advance based on the system usage history information. Furthermore, the user may register the communication speed information in the server system 100 in advance for each communication standard used by the information terminal device 200. Further, the system information acquisition unit 120 may acquire the network type and the like as system information in addition to the communication speed.

  Next, the image acquisition unit 110 acquires a processing target image (T302), and transmits information about the acquired processing target image and an image such as an image size to the image processing unit 140 (T303).

  Then, the system information acquisition unit 120 acquires two types of system information (communication speed, etc.) regarding the 3G line and the WiFi line from the image processing unit 140 (T304), and outputs the acquired two types of communication speeds, etc. It transmits to 160 (T305).

  Next, the output count determination unit 160 determines the output count for the 3G line as 3 and the output count for the WiFi line as 2 (T306), and transmits the determined output count to the parameter determination unit 130 (T307). ).

  In addition, the parameter determination unit 130 is a system such as the information related to the image (the size of the result image), the information related to the image processing (processing load, etc.), and the information related to the processing capability (spec information of the image processing unit 140, etc.). Information is acquired from the system information acquisition unit 120 (T308).

  Then, the parameter determination unit 130 determines an image processing parameter for obtaining each output image based on the information regarding the image processing acquired in T308 and the number of outputs acquired in T307 (T309). At this time, the parameter determination unit 130 determines the image processing parameter so as not to exceed the upper limit value of the transmittable data size of the result image set for each communication standard. For example, the upper limit value of the transmittable data size is set to 500 KB for a 3G line and unlimited for WiFi.

  Next, the parameter determination unit 130 transmits the determined image processing parameter to the image processing unit 140 (T310).

  Then, the image processing unit 140 performs image processing on the processing target image acquired from the image acquisition unit 110 based on the image processing parameters for the 3G line acquired from the parameter determination unit 130 (T311), and the result image is displayed. The data is output to the transmission processing unit 150 (T312).

  Further, the transmission processing unit 150 transmits the result image to the reception processing unit 210 of the information terminal device 200 via the currently connected 3G line (T313). For example, when transmitting and receiving data via a 3G line, the upper limit value of the transmittable data size is set to 500 KB, so that the 5 MB processing target image is reduced to a size of 500 KB or less, and the reduced image is Image processing is performed and the result image is transmitted.

  Then, the information terminal device 200 performs an appropriate process according to the usage such as displaying or saving the result image (T314).

  Further, the image processing unit 140 performs image processing based on the first image processing parameter for the WiFi line acquired from the parameter determination unit 130 (T315), and outputs the result image to the transmission processing unit 150 (T316). Note that the image processing for the WiFi line may be started after connecting to the WiFi line.

  Here, the transmission processing unit 150 attempts to transmit the result image to the reception processing unit 210 of the information terminal device 200 via the WiFi line, but is connected to the information terminal device 200 via a 3G line. The transmission process of the result image for the line is not performed (T317).

  Here, as described above, it is assumed that the user has moved from P1 to P2 in FIG. Then, the information terminal device 200 changes the connection destination from the 3G line to the WiFi line and reconnects to the server system 100. Accordingly, the number of times of output is determined again from 3 times for 3G to 2 times for WiFi. The re-determination of the number of outputs will be described later in detail with reference to FIGS. 12 (A) to 12 (C).

  At this time, the image processing unit 140 performs image processing based on the second image processing parameter for the WiFi line acquired from the parameter determination unit 130, generates a result image (T318), and transmits the result image to the transmission processing unit. 150 (T319).

  Furthermore, since the transmission processing unit 150 is connected to the information terminal device 200 via a WiFi line, the transmission processing unit 150 transmits the first result image for the WiFi line that was not transmitted in T317 to the information terminal device 200 (T320). And the information terminal device 200 performs an appropriate process according to a use, such as displaying or saving a result image (T320). At this point, since the transmission processing unit 150 has acquired the second result image from the image processing unit 140, the first result image transmission process may be omitted.

  Next, the transmission processing unit 150 transmits the second result image for the WiFi line to the information terminal device 200 (T321). Similar to T320, the information terminal device 200 performs an appropriate process depending on the application, such as displaying or storing the result image.

  In the example described above, when a 3G line is used, three result images (OIM1 to OIM3) are transmitted from the server system SV to the information terminal device TU as shown in FIG.

  However, as shown in FIG. 11B, the line may be disconnected when the transmission of the second result image OIM2 is completed.

  In this case, when the transmission processing unit 150 manages the transmission status for each user or session and the server system 100 and the information terminal device 200 are next reconnected by the same line, the transmission processing unit 150 is shown in FIG. Thus, only the third result image OIM3 may be transmitted.

  Also, even if the network to which the user is currently connected is a 3G line, processing is performed on an image of 5 MB from the beginning in accordance with the WiFi line, and the data size of the result image is adjusted to 500 KB or less to obtain a 3G line. The original image may be automatically transmitted after being delivered via the Wi-Fi line.

  Also, it was decided to output twice on the WiFi line, but if the processing request is accepted on the 3G line and then the process moves to the WiFi line, if the processing of the highest quality image is completed at the time of transition, This image may be transmitted once and completed.

  If the upper limit size is more strict and it is difficult to transmit the image, the result is stored in the server system 100 or another server device after the processing of the original image is completed, and link information to the image is transmitted to the information terminal device 200. You may do it. According to this, after the user moves to a place where the communication speed is faster, the user can click the link himself and access the image. Further, only the image processing request is transmitted to the server system 100 from the mobile terminal when going out, and after returning home, the user logs in to the server system with the same user ID from a device such as a PC monitor or TV having a larger display panel size, A method of confirming the processing result is also possible.

  Conversely, when the WiFi line is shifted to the 3G line, it is possible to complete the processing and adjust the data amount from the result image to the upper limit size before delivery.

5.3. Method Next, the method of the present embodiment will be described.

  In the server system 100 of the present embodiment, the system information acquisition unit 120 acquires the first system information when the system is in the first state, and after the acquisition of the first system information, the system is in the second state. The second system information in the case of Then, the output number determination unit 160 may determine the first output number based on the first system information, and may determine the second output number based on the second system information. Further, when the image processing unit 140 determines that the system is in the first state, the image processing unit 140 performs image processing for the number corresponding to the first output count, and determines that the system is in the second state. In that case, image processing may be performed by the number corresponding to the second number of outputs. If the transmission processing unit 150 determines that the system is in the first state, the transmission processing unit 150 transmits information on each result image to the information terminal device 200 as many times as the first output count. When it is determined that the state is in the state, information of each result image may be transmitted to the information terminal device 200 by the second output count.

  For example, both the first output count and the second output count are determined regardless of the acquisition timing of the first system information and the second system information so that an immediate response can be made when the system status changes. You may keep it. That is, even when there is a time difference in acquiring system information, the number of outputs may be obtained.

  Further, when there is a margin in the processing capability of the image processing unit 140, image processing is performed in advance for the number corresponding to the first output count, and image processing is performed for the number corresponding to the second output count. You may keep it.

  Here, the first system information means system information acquired when the system is in the first state, and the second system information is acquired when the system is in the second state. System information.

  Further, the first output count refers to the output count determined based on the first system information, and the second output count refers to the output count determined based on the second system information. That means.

  Furthermore, the number corresponding to the first output count may be the same as the first output count, or may be a number associated with each value of the first output count. Specifically, when the number associated with each value of the first output count is used, for example, the first output count is 2 times, and 1 is assigned as the number of times of image processing. If it is. In this case, the same result image is transmitted twice without performing image processing only once. The same applies to the number corresponding to the second output count.

  Accordingly, it is possible to set different output counts for the case where the system is in the first state and the case where the system is in the second state. That is, it is possible to set an appropriate number of outputs according to each state.

  In the above-described example, the image processing parameter is obtained after obtaining the output count once from the system information. However, the present invention is not limited to this, and the first image processing parameter is obtained directly from the first system information. The second image processing parameter may be obtained directly from the information.

  That is, the system information acquisition unit 120 acquires the first system information when the system is in the first state, and after the acquisition of the first system information, the second information when the system is in the second state. System information may be acquired. At this time, the parameter determination unit 130 may determine the first image processing parameter based on the first system information, and may determine the second image processing parameter based on the second system information. Then, the image processing unit 140 may perform image processing on the processing target image according to the first image processing parameter, and may perform image processing on the processing target image according to the second image processing parameter. Further, if the transmission processing unit 150 determines that the system is in the first state, the transmission processing unit 150 performs processing for transmitting the result image generated based on the first image processing parameter, and the system is in the second state. If it is determined that the result image is, the processing may be performed to transmit the result image generated based on the second image processing parameter.

  This makes it possible to determine in advance image processing parameters corresponding to a plurality of system states. In addition, it is possible to reserve processing (or advance processing) so that processing results can be output immediately when the system state changes.

  The first state described above may be a state where the network 500 uses the first communication standard, and the second state may be a state where the network 500 uses the second communication standard.

  That is, the system information acquisition unit 120 acquires the system information when the network 500 is in the first state using the first communication standard as the first system information, and after acquiring the first system information, The system information when the network 500 is in the second state using the second communication standard whose communication speed is faster than the first communication standard may be acquired as the second system information.

  Here, the first communication standard refers to a communication standard used when the server system 100 and the information terminal device 200 are connected. Specifically, TDMA, GSM (registered trademark) (2G), CDMA, WCDMA (registered trademark) (3G), HSPA (3.5G), LTE (registered trademark) (3.9G), LTE-Advanced (4G) ) Etc. Also included are proximity wireless communications such as WiFi (registered trademark), wireless LAN, Bluetooth (registered trademark), and Transferjet (registered trademark) using the communication standard IEEE 802.11.

  The second communication standard refers to a communication standard having a higher communication speed than the first communication standard. A specific example of the second communication standard is the same as that of the first communication standard.

  As a result, it is possible to determine the number of outputs based on the type of communication standard used by the server system 100 and the information terminal device 200 during communication.

  The first state described above is a state in which the first processing load is applied to the image processing unit 140, and the second state is a state in which the second processing load that is larger than the first processing load is the image processing unit. 140 may be applied.

  That is, the system information acquisition unit 120 acquires the system information when the first processing load is in the first state applied to the image processing unit 140 as the first system information, and acquires the first system information. Later, system information in a second state in which a second processing load greater than the first processing load is applied to the image processing unit 140 may be acquired as second system information.

  As a result, it is possible to determine the number of outputs based on the size of the processing load applied to the image processing unit 140. For example, in the second state, the processing load on the image processing unit 140 is larger than that in the first state, so the size of the processing target image to be subjected to image processing is reduced, Some processing with a large calculation amount is not performed. On the other hand, in the case of the first state, an image processing parameter that also executes processing with a large calculation amount is determined.

  Further, as described above, when the network state changes and the communication speed changes, the output count re-determination process may be performed. For example, the communication speed may change when the communication standard to be used is changed as shown in FIG. 9 or when the user moves to a place with less noise and a good communication environment.

  Specifically, the output count redetermination process will be described with reference to FIGS. First, at the time of FIG. 12A, the server system SV and the information terminal device TU are connected via a 3G line, the number of times of output is set to 3, and the server system SV receives the first result image OIM1. Is transmitted.

  Then, when the information terminal device TU has received the first result image OIM1, the communication terminal is switched to a state in which communication is performed via the WiFi line, and the communication speed is increased as shown in FIG. To do. In this case, the number of outputs is changed from 3 times to 2 times. Furthermore, in the example of FIG. 12B, since the first result image OIM1 has already been transmitted, the first result image OIM1 is not transmitted again. Further, since the number of times of output is changed to 2, the transmission of the second result image OIM2 is also stopped, and only the third result image OIM3 is transmitted. At this time, the third result image OIM3 may be a newly generated image. If the third result image OIM3 is generated at the time of FIG. The same image may be used.

  On the other hand, as shown in FIG. 12C, when the communication speed decreases and the third result image OIM3 cannot be transmitted by the output limit time, the number of times of output is determined again from 3 times to 4 times. Also good. In this case, a fourth result image OIM4 having an intermediate size between the second result image OIM2 and the third result image OIM3 is newly generated. Next to the second result image OIM2, the fourth result image OIM4 is generated. And the third result image OIM3 is transmitted next to the fourth result image OIM4.

  That is, the system information acquisition unit 120 may detect a change in the state of the image processing system and acquire the change detection information. And the transmission process part 150 may acquire the transmission history information showing the transmission history of the information of the 1st result image-the Nth result image. Furthermore, the output count determination unit 160 may redetermine the output count of the result image based on the change detection information and the transmission history information.

  Here, the change detection information refers to information indicating that a change in the data transfer speed (communication speed) of the network is detected in the examples of FIGS. 12A to 12C, for example. The change detection information is not limited to this, and may be information indicating that the processing load on the image processing unit 140 has been changed, for example.

  The transmission history information is information indicating which result image has been transmitted among a plurality of result images generated from one processing target image. For example, in the examples of FIGS. 12B and 12C, the information indicating that the first result image OIM1 has been transmitted among the first result images OIM1 to OIM3. Point to.

  This makes it possible to add or change the necessary result output without duplicating the previously transmitted results.

  In addition to re-determining the number of outputs based on the change detection information, the image processing parameters may be re-determined based on the change detection information.

  That is, the parameter determining unit 130 determines the first image processing parameter to the Nth image processing parameter based on the system information when the determined number of outputs is N times (N is an integer equal to or greater than 2). May be. Then, the image processing unit 140 performs image processing on the processing target image in accordance with the first image processing parameter to the Nth image processing parameter, and generates a first result image to an Nth result image. You may start. Further, the transmission processing unit 150 may start a process of transmitting information on the first result image to the Nth result image to the information terminal device 200. At this time, the system information acquisition unit 120 may detect a change in the state of the image processing system and acquire the change detection information. And the transmission process part 150 may acquire the transmission history information showing the transmission history of the information of the 1st result image-the Nth result image. Further, when the parameter determination unit 130 determines that the information of the p-th result image to the N-th result image is incomplete transmission based on the transmission history information, the parameter determination unit 130 performs the p-th operation based on the change detection information. The image processing parameter to the Nth image processing parameter may be redetermined. Note that p is an integer of 1 ≦ p <N.

  As a result, as in the case of re-determining the number of outputs, it is possible to add or change a necessary result output without redundantly transmitting previously transmitted results. Note that image processing and transmission processing may be performed in parallel.

  Further, when the server system 100 is reconnected to the information terminal device 200, the server system 100 may transmit only the result image that has not been transmitted last time without retransmitting the result image that has been transmitted at the time of previous connection.

  That is, when the transmission processing unit 150 detects reconnection with the information terminal device 200, the transmission processing unit 150 acquires transmission history information indicating the transmission history of the result image to the information terminal device 200, and transmits the transmission history information based on the transmission history information. You may restart the process which transmits the information of the completion result image.

  Accordingly, it is possible to reduce unnecessary processing such as regenerating or transmitting a result image transmitted to the information terminal device 200 at the previous connection each time reconnection is performed.

  Furthermore, if all image processing has been completed when reconnected, only the last generated image may be sent. This is because the image that the user wants to acquire is the image generated last.

  That is, the image processing unit 140 may generate the second result image after generating the first result image. When the transmission processing unit 150 acquires the first result image and the second result image from the image processing unit 140 and then detects reconnection with the information terminal device 200, the transmission processing unit 150 receives information on the first result image. The information of the second result image may be transmitted to the information terminal device 200 without transmitting.

  As a result, when the final result image has already been generated at the time of reconnection, it is possible to transmit only the final result image without transmitting the preview image.

6). Fourth Embodiment 6.1. System Configuration Example The system configuration of this embodiment is the same as the system configuration of the second embodiment shown in FIG.

6.2. Processing Details In this embodiment, the communication time and the image processing time are determined based on the output limit time, and the specific image processing is performed based on both the determined communication time and the image processing time. Determine the parameters. In the present embodiment, the user specifies the number of outputs and the output limit time (output timing). In the present embodiment, the system information acquisition unit 120 acquires the communication speed and the processing load of the image processing unit 140 as system information.

  Here, the flow of the image processing parameter determination process performed by the parameter determination unit 130 of this embodiment will be described using the flowchart of FIG.

  First, weights for communication time and image processing time are determined (S401). In other words, the ratio of the communication time to the output limit time and the processing time of the image processing is determined. That is, it determines how much of the output limit time is allocated to the communication time and how much time is allocated to the image processing time. For example, the weighting is performed so that the time ratio between the communication time and the image processing time is 2: 1.

  Next, the output time limit is acquired (S402). Here, the number of times of output is three times, and the output limit time is within 30 seconds for the first time, within 5 minutes for the second time, and there is no limit for the third time.

  Then, based on the determined weight and output limit time, the processing time (S403) and the communication time are determined (S404).

  In this example, since the output limit time is 30 seconds in the first process, 20 seconds is assigned as the communication time and 10 seconds is assigned as the image processing time. In the second process, since the output limit time is 5 minutes, 200 seconds is assigned as the communication time, and 100 seconds is assigned as the image processing time. In the third process, since there is no limit on the output time limit, the communication time and the image processing time are not determined.

  Next, the size of the result image is determined based on the determined communication time (S405), and the image processing parameter is determined based on the size of the result image and the processing time of the image processing (S406). The decision process is terminated.

  For example, when determining the first image processing parameter, first, an image size of a processing result that can be transmitted within 20 seconds allocated as a communication time is obtained. Based on the processing time of the assigned image processing and the image size of the processing result, image processing parameters that satisfy these are determined. Specific contents of the image processing parameter include, for example, the size of a filter window when applying a Gaussian filter. Note that image processing parameter determination processing is performed in the same manner for the second time. For the third time, it is not necessary to consider communication time and image processing time.

6.3. Method Next, a method of the present embodiment will be described.

  In the server system 100 of the present embodiment, the system information acquisition unit 120 may acquire processing capability information representing the processing capability of the image processing unit 140 as system information. Then, the parameter determination unit 130 may determine the data size of the result image to be generated based on the processing capability information, and may determine an image processing parameter corresponding to the determined data size.

  Here, the processing capability information is one piece of information indicating the state of the image processing unit 140 described above. For example, information such as a CPU clock frequency (operation frequency), a memory capacity, the number of CPU cores, and a CPU architecture. Point to.

  This makes it possible to control the processing time of image processing.

  Note that the server system, the image processing system, and the like of the present embodiment may realize part or most of the processing by a program. In this case, a server system, an image processing system, and the like according to the present embodiment are 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 according to the present embodiment based on a program (data) stored in the information storage medium. That is, in the information storage medium, a program for causing a computer (an apparatus including an operation unit, a processing unit, a storage unit, and an output unit) to function as each unit of the present embodiment (a program for causing the computer to execute processing of each unit) Is memorized.

Accordingly, all such modifications are intended to be included in the scope of the present invention.
