Description

The present invention relates to an information processing device, an information processing method, and a program that executes development processing.

In recent years, a technology has been used in which a server performs image processing on still images and videos uploaded from a user device, such as a personal computer (PC), and presents the results of the processing to the user device. This technology achieves efficient image processing (video processing) using the high processing power of the server. It is expected that in the future, this technology will also be widely applied to large-capacity videos, such as RAW videos, in which data from an image sensor is recorded directly for each frame.

Patent document 1 discloses a technology that reduces the load of development processing by extracting data indicated in editing information that specifies the playback section of RAW data from storage and performing development processing on the extracted data.

JP 2009-171060 A

Patent Document 1 is a technology related to development processing by a single user, and does not assume the existence of multiple users. In cases where multiple users process a single RAW video on a server (for example, multiple parents process a video of a child's recital), the single RAW video is edited and developed according to the preferences and requests of each user. Therefore, in such cases, it becomes necessary to perform multiple development processes on a single RAW video in response to different instructions from multiple users. However, if multiple development processes are performed within a short period of time, the processing load on the server becomes excessive. The above issues can also occur in development processes for videos other than RAW videos.

In view of the above, the present invention aims to provide an information processing device, an information processing method, and a program that can reduce the load of video development processing.

In order to achieve the above-mentioned object, the information processing device of the present invention comprises an editing means that performs a predetermined editing process on the RAW video in accordance with editing information transmitted from a plurality of devices including a user device and another user device, to identify a range of a temporal range of the RAW video that is unnecessary for a user of the device that transmitted the editing information, and a developing means that performs either a first developing process or a second developing process having a smaller processing load than the first developing process on the temporal range of the RAW video , wherein when a request to play the RAW video is received from the user device and the editing information transmitted from the user device is not held , the developing means performs the second developing process on a range of the temporal range of the RAW video that is unnecessary for the user of the other user device, identified in accordance with the editing information transmitted from the other user device, and performs the first developing process on another temporal range of the RAW video.

The present invention reduces the load of video development processing on an information processing device.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Each embodiment described below is merely one example of a configuration that can realize the present invention. Each of the following embodiments can be modified or changed as appropriate depending on the configuration of the device to which the present invention is applied and various conditions. Therefore, the scope of the present invention is not limited by the configurations described in each of the following embodiments. For example, a configuration that combines multiple configurations described in the embodiments can be adopted as long as they are not mutually contradictory.

First Embodiment
1 is a diagram showing the overall configuration of an information processing system S according to a first embodiment of the present invention. The information processing system S includes a server 100 (information processing device) and a plurality of PCs 150 (user devices). Each PC 150 can communicate with the server 100 via a network.

In general terms, the server 100 performs development processing on the RAW video stored on the server 100 according to the editing content sent from each PC 150, and then sends the development results to each PC.

The configurations of the server 100 and PC 150 according to the first embodiment of the present invention will be described with reference to FIG. 2. FIG. 2(a) is a block diagram showing the configuration of the server 100 according to this embodiment, and FIG. 2(b) is a block diagram showing the configuration of the PC 150 according to this embodiment.

As shown in FIG. 2(a), the server 100 has a CPU 101, a ROM 102, a RAM 103, a HDD 104, a network IF 105, a user IF 106, a VRAM 107, an image processing unit 108, and a display control unit 109. These elements are interconnected by an internal bus 115, which is a transmission path for control signals and data signals.

The CPU 101 (control means) is a processing circuit that executes various calculations in the server 100. The ROM 102 is a non-volatile storage medium that stores various control programs and data used by the CPU 101. The RAM 103 is a volatile storage medium that stores setting values used by the CPU 101 and functions as a working memory in which various programs are deployed. The hard disk drive (HDD) 104 is a non-volatile storage medium that stores various programs and data that constitute the application AP and the operating system (OS).

The network IF 105 is a connection interface with the network 111, and is, for example, a network interface card (NIC). The user IF 106 is a connection interface with input devices 112 such as a mouse 113 and a keyboard 114, and is, for example, a USB interface.

The VRAM 107 is a volatile storage medium that stores image data. The image processing unit 108 is a processing device that processes image data and supplies it to the display control unit 109. The display control unit 109 is a control device that displays images on a display 110 connected to the server 100.

As shown in FIG. 2(b), the PC 150 has a CPU 151, a ROM 152, a RAM 153, a HDD 154, a network IF 155, a user IF 156, a VRAM 157, an image processing unit 158, and a display control unit 159. The above elements are interconnected by an internal bus 165, which is a transmission path for control signals and data signals. The above elements are configured in the same way as the corresponding elements of the server 100.

The CPUs 101, 151 of the server 100 and the PC 150 respectively read out and execute the programs stored in the ROMs 102, 152 and the HDDs 104, 154 into the RAMs 103, 153, thereby implementing various processes according to this embodiment. The HDD 104 stores the RAW video that is the subject of the editing process described below.

Note that, hereinafter, the execution of a certain process X by the CPU 101 of the server 100 while controlling other elements in the server 100 in an integrated manner may be expressed simply as "the server 100 executes the process X." Similarly, the execution of a certain process Y by the CPU 151 of the PC 150 while controlling other elements in the PC 150 in an integrated manner may be expressed simply as "the PC 150 executes the process Y."

Figure 3 is an explanatory diagram illustrating an example of a display screen of application AP according to the first embodiment of the present invention. This application AP is executed in PC 150, and processes video in response to user operations on input device 112. When PC 150 executes application AP, a display screen 300 including the following display areas is displayed on display 160.

As shown in FIG. 3, the display screen 300 includes a video list area 310, a preview area 320, a control area 330, and a timeline area 340 as display areas.

The video list area 310 is an area that displays the file names of RAW videos stored in the HDD 104 of the server 100 and the HDD 154 of the PC 150. The PC 150 can obtain the file names of the RAW videos in the HDD 104 of the server 100 via the network. In FIG. 3, four RAW videos AAAA, BBBB, CCCC, and DDDD stored in folder 311 are displayed. Thumbnails of the RAW videos may be displayed in the video list area 310 together with the file names.

Preview area 320 is an area in which the RAW video selected by the user is played and displayed. Server 100 develops a specific frame of the RAW video selected by the user and transmits the developed display data (development result) to PC 150. PC 150 displays the developed display data received from server 100 in preview area 320.

The control area 330 is an area that displays software buttons for controlling the playback of the RAW video displayed in the preview area 320. The user can control the playback of the video by operating the software buttons using the mouse 113.

The timeline area 340 is an area used for editing the RAW video (cut editing, etc.). The timeline area 340 displays a rectangle 341 that chronologically indicates the playback range of the RAW video selected by the user. The editing positions 342 and 343 are marks that indicate the section (temporal range) that remains after a cut editing process that deletes a section of the RAW video, and their positions are changed based on the user's operation. The playback bar 350 is a mark that indicates the current playback position in the RAW video.

The application AP also has functions not shown in FIG. 3, such as a function to adjust RAW development parameters such as white balance, color temperature, brightness, and sharpness, and a function to set parameters when exporting a RAW video file in a different format.

The operation of the server 100 and PC 150 according to the first embodiment of the present invention will be described with reference to Figures 4 to 6.

Figures 4(a) and 4(b) are flowcharts showing the operations of the server 100 and the PC 150 when developing and displaying a RAW video. More specifically, Figure 4(a) shows the operation of the PC 150 which displays the development results of the RAW video in the preview area 320 described above, and Figure 4(b) shows the operation of the server 100 which transmits the development results of the RAW video developed based on a development request from the PC 150. Figures 4(a) and 4(b) are executed in parallel with the cooperation of the server 100 and the PC 150.

In step S401, the PC 150 determines whether the user has used the input device 112 to issue an instruction to display the RAW video. The above display instruction is an instruction to update the image displayed in the preview area 320, and may include information indicating a specific frame from which display should begin. A user operation equivalent to a display instruction is, for example, an operation to select a RAW video displayed in the video list area 310, or an operation to move the playback bar 350 displayed in the timeline area 340. If the user simply selects the RAW video itself, the display instruction may mean an instruction to begin displaying from the first frame of the RAW video. When the PC 150 receives a display instruction (S401: YES), it proceeds to step S402, and while the PC 150 has not received a display instruction (S401: NO), it repeats the wait loop of step S401.

In step S402, the PC 150 transmits to the server 100 a request to develop the RAW video indicated in the display instruction determined in step S401. The development request includes the file name of the RAW video to be developed, the number of the specific frame from which display should begin, and the RAW development parameters. After transmitting the development request, the PC 150 proceeds to step S403.

In step S411, the server 100 determines whether or not a development request for a RAW video has been received from the PC 150. If the server 100 receives a development request (S411: YES), the server 100 proceeds to step S412, and if the server 100 has not received a development request (S411: NO), the server 100 repeats the waiting loop of step S411.

In step S412, the server 100 reads the frame data for a specific frame number from the RAW video file stored in the HDD 104 based on the file name of the RAW video and the number of a specific frame indicated in the development request received from the PC 150.

In step S413, the server 100 executes a development process on the frame data read in step S412 using the RAW development parameters indicated in the development request received from the PC 150. The development result obtained by the above development process is, for example, RGB format image data developed based on the RAW development parameters. The development result may be compressed according to any compression method such as JPEG.

In step S414, the server 100 transmits the development results of the development process executed in step S413 to the PC 150 that sent the development request, and ends the process of FIG. 4(b).

In step S403, PC 150 determines whether or not it has received from server 100 the development results corresponding to the development request sent in step S402. If PC 150 receives the development results (S403: YES), it proceeds to step S404, and if it has not received the development results (S403: NO), it repeats the waiting loop of step S403.

In step S404, the PC 150 displays the received development result determined in step S403 in the preview area 320, and ends the process of FIG. 4(a).

Figures 4(c) and 4(d) are flowcharts showing the operations of the server 100 and the PC 150 when the user has finished editing the RAW video. More specifically, Figure 4(c) shows the operation of the PC 150 to send editing information indicating the editing content by the user to the server 100, and Figure 4(d) shows the operation of the server 100 to receive the editing information from the PC 150. As described above, Figures 4(c) and 4(d) are executed in parallel with the cooperation of the server 100 and the PC 150.

In step S421, the PC 150 determines whether the user has used the input device 112 to issue an instruction to complete editing of the RAW video. The above completion instruction may be, for example, an operation to cut and edit the RAW video and export it in a different file format, or an operation to temporarily save the cut-edited RAW video. When the PC 150 receives a completion instruction (S421: YES), it proceeds to step S422, and while the PC 150 has not received a completion instruction (S421: NO), it repeats the wait loop of step S421.

In step S422, the PC 150 transmits editing information for the RAW video related to the completion instruction in step S421 to the server 100, and ends the process in FIG. 4(c). The above editing information includes identification information such as a user identifier that identifies the user who instructed the editing, the file name of the edited RAW video, the numbers or time codes of the first and last frames that identify the cut section, and the development settings for each frame.

In step S431, the server 100 determines whether or not editing information has been received from the PC 150. If the server 100 receives editing information (S431: YES), the server 100 proceeds to step S432, and if editing information has not been received (S431: NO), the server 100 repeats the waiting loop of step S431.

In step S432, the server 100 stores the editing information received from the PC 150 in the HDD 104 and ends the process of FIG. 4(d).

The above-mentioned processes in FIG. 4(a) and FIG. 4(c) may be executed by a plurality of PCs 150 that can access the server 100. Editing information transmitted from each of the plurality of PCs 150 based on the editing work of a plurality of users is associated with a user identifier and stored in the HDD 104 of the server 100.

Figure 5 is a flowchart showing the development control process of the server 100 regarding the playback of RAW video. Figure 5(b) is a flowchart that details step S503 in Figure 5(a).

In step S501, the server 100 determines whether or not a playback request for a RAW video has been received from the PC 150. If the server 100 receives a playback request (S501: YES), the server 100 proceeds to step S502, and if the server 100 has not received a playback request (S501: NO), the server 100 repeats the wait loop of step S501.

The above playback request is data that PC 150 sends to server 100 in response to a user operation such as pressing the play button in control area 330. The above playback request also includes the file name and playback position of the RAW video to be played (e.g., the frame number indicating the target frame of the RAW video being displayed), as well as the user identifier of the user who performed the operation related to the playback request. Hereinafter, the user of PC 150 who sent the request to play the RAW video will be referred to as the "requesting user," and users other than the requesting user will be referred to as "other users."

In step S502, the server 100 determines whether or not editing information associated with the user identifier included in the playback request is stored in the HDD 104 for the RAW video related to the playback request received in step S501. If editing information for the requesting user exists (S502: YES), the server 100 proceeds to step S504. If editing information for the requesting user does not exist (S502: NO), the server 100 proceeds to step S503.

In step S503, the server 100 executes steps S511 to S516 shown in FIG. 5(b). The details will be described later, but in general, the development process is controlled based on the editing information of other users.

In step S504, the server 100 reads and acquires from the HDD 104 the editing information of the requesting user for the RAW video to be played.

In step S505, the server 100 executes development processing based on the development settings indicated in the editing information of the requesting user read in step S504 at the playback position (target frame) indicated by the playback request, and transmits the development results to the PC 150 that sent the playback request. The PC 150 displays the development results received from the server 100 in the preview area 320.

After this, the server 100 continues the development process of the RAW video and the transmission process of the development results starting from the playback position indicated by the playback request. However, if the server 100 receives a playback stop request from the PC 150 that sent the playback request, or if playback of the RAW video ends (i.e., the development process and transmission process for the final frame of the RAW video are completed), the server 100 stops the development process and transmission process.

Next, the processing of steps S511 to S516 included in step S503 will be described with reference to FIG. 5(b).

In step S511, the server 100 reads and acquires from the HDD 104 the editing information of other users for the target frame for which development processing is to be performed. When step S511 is performed for the first time, the target frame is the position at which playback indicated by the playback request is to start.

In step S512, the server 100 determines whether the number n of editing information (number of edits) of other users in the target frame is equal to or greater than a predetermined threshold N. If the number n of editing information is equal to or greater than the threshold N (S512: YES), the server 100 proceeds to step S513, and if the number of editing information is less than the threshold N (S512: NO), the server 100 proceeds to step S515.

In step S513, the server 100 determines whether the number m of editing information whose editing content is "cut" (number of cut edits) among the editing information of other users in the target frame is equal to or greater than a predetermined threshold value M. If the number m of the corresponding editing information is equal to or greater than the threshold value M (S513: YES), the server 100 proceeds to step S514, and if the number m of the corresponding editing information is less than the threshold value M (S512: NO), the server 100 proceeds to step S515.

In step S514, the server 100 executes a simple development process (simple development) on the target frame and transmits the development results of the simple development to the PC 150 that sent the playback request. The PC 150 displays the development results received from the server 100 in the preview area 320.

The above simplified development processes impose a lighter processing load on the CPU 101 than normal development processes, such as development processes that omit some processes or development processes for RAW video with reduced resolution. Examples of processes that may be omitted include, but are not limited to, sharpness processing, noise reduction processing, false color suppression processing, and moiré suppression processing.

In step S515, the server 100 executes normal development processing (normal development) on the target frame and transmits the development results of the normal development to the PC 150 that sent the playback request. The PC 150 displays the development results received from the server 100 in the preview area 320.

In step S516, the server 100 determines whether the current target frame is the final frame of the RAW video. If the target frame is the final frame (S516: YES), the server 100 ends the process. If the target frame is not the final frame (S516: NO), the server 100 advances the target frame to the next frame and returns the process to step S511.

Figure 6 is an explanatory diagram of the target section for simple development (simple development section) realized by the above process (particularly steps S513 and S514 in Figure 5(b)). Figure 6 shows the partial playback range (00:00:00:00 to 00:05:00:00) of RAW videos related to multiple users using time codes.

As shown in the figure, three other users 1 to 3 have cut and edited different sections ( time ranges) of the same RAW video AAAA. Other user 1 cuts the section 00:02:00:00 to 00:03:00:00, other user 2 cuts the section 00:02:10:00 to 00:02:50:00, and other user 3 cuts the section 00:01:45:00 to 00:02:55:00.

The section cut in common by the three other users 1 to 3 is the common cut section 00:02:10:00 to 00:02:50:00. In other words, the number of cut edits m in the common cut section 00:02:10:00 to 00:02:50:00 is "3". If the threshold M in step S513 is "3", the determination in step S513 will be YES for the above common cut sections and NO for the other sections. As a result, simple development is applied to the common cut section 00:02:10:00 to 00:02:50:00.

Sections cut by many users are likely to be sections that are of low importance to the users, so there is little chance of problems occurring even if the video quality is low. In response to a playback request from a requesting user who has not performed editing, simple development is applied to the RAW video (target frames) of sections that are likely to be cut by other users, making it possible to achieve both video quality for sections (ranges) of high importance and a reduced processing load on the server 100.

In FIG. 6, simple development is applied to sections that were commonly cut by multiple other users (i.e., sections where multiple cut sections are joined with an AND condition) (M = number of editing users). However, simple development may also be applied to sections that were cut by any of multiple other users (i.e., sections where multiple cut sections are joined with an OR condition) (M = 1).

According to the configuration of this embodiment described above, a development processing method for a RAW video (target frame) is selected according to editing information indicating the editing content by the user. As a result, the load of video development processing on the server 100 can be reduced.

Second Embodiment
A second embodiment of the present invention will be described below. In each of the embodiments exemplified below, for elements whose actions and functions are equivalent to those of the first embodiment, the reference numerals referred to in the above description will be used and the description of each will be omitted as appropriate. The configurations and operations of the first embodiment shown in Figs. 1 to 4 are applied mutatis mutandis to the second embodiment.

In the first embodiment, the development process is controlled based on editing information that indicates the editing content (cut editing, etc.) for a section that is a time range. In the second embodiment, the development process is controlled based on editing information that indicates the editing content (crop editing, etc.) for an image area range.

Figure 7 is a flowchart showing the development control process of the server 100 regarding the playback of RAW video. Figure 7(b) is a flowchart detailing step S703 in Figure 7(a). Steps S701, S702, S704, and S705 in Figure 7(a) are similar to steps S501, S502, S504, and S505 in Figure 5(a) of the first embodiment, and therefore will not be described.

The processing of steps S711 to S717 included in step S703 will be described with reference to FIG. 7(b). Steps S711, S712, S716, and S717 in FIG. 7(b) are similar to steps S511, S512, S515, and S516 in FIG. 5(b) of the first embodiment, and therefore will not be described.

In step S713, the server 100 determines whether the number m of editing information whose editing content is "crop" (the number of crop edits) among the editing information of other users read in step S711 is equal to or greater than a predetermined threshold value M. Here, cropping refers to an editing process in which a portion of the entire area of a frame is cut out, and is described below with reference to FIG. 8. If the number m of the corresponding editing information is equal to or greater than the threshold value M (S713: YES), the server 100 proceeds to step S714, and if the number m of the corresponding editing information is less than the threshold value M (S712: NO), the server 100 proceeds to step S716.

In step S714, the server 100 refers to the editing information related to crop editing and identifies the common uncropped areas (areas 0 to s1, e3 to W in Figure 8) in the target frame that have not been cropped by any other users.

In step S715, the server 100 performs simple development on the common uncropped area identified in step S714, while performing normal development on the other cropped areas. The server 100 transmits the development results of the target frame that includes the simple development area and the normal development area to the PC 150 that transmitted the playback request. The PC 150 displays the development results received from the server 100 in the preview area 320.

Figure 8 is an explanatory diagram of the target area for simple development (simple development area) realized by the above process (particularly steps S713 to S715 in Figure 7(b)). Figure 8 shows image areas 0 to W in one frame of a RAW video.

As shown in the figure, three other users 1-3 are cropping and editing different regions (spatial ranges) of the same RAW video frame. Other user 1 crops the region s1-e1, other user 2 crops the region s2-e2, and other user 3 crops the region s3-e3.

The areas cropped by any of the three other users 1 to 3 are cropped areas s1 to e3. In other words, the areas not cropped by any of the three other users 1 to 3 (common uncropped areas) are areas 0 to s1 and e3 to W. Therefore, the above common uncropped areas are identified in step S714, and simple development is performed on the common uncropped areas in step S715.

Areas that are not cropped by many users are likely to be areas that are of low importance to the users, so there is little chance of problems occurring even if the video quality is low. By applying simple development to areas within the frame that are not cropped by other users in response to a playback request from a requesting user who is not performing editing, it is possible to achieve both video quality in areas (ranges) that are of high importance and a reduction in the processing load on the server 100.

In FIG. 8, simplified development is applied to areas that are not cropped by multiple other users (i.e., areas where multiple uncropped areas are combined with an AND condition). However, simplified development may also be applied to areas that are not cropped by a predetermined number of other users.

Note that, for simplicity of explanation, FIG. 8 illustrates a configuration in which crop editing is applied in the horizontal direction. However, the processing of this embodiment can be applied to a configuration in which crop editing is applied in the vertical direction, and to a configuration in which crop editing is applied in both the horizontal and vertical directions.

According to the configuration of this embodiment described above, a development processing method for the RAW video (target area) is selected according to editing information indicating the editing content by the user. As a result, the load of video development processing on the server 100 can be reduced.

<Modification>
The above embodiment may be modified in various ways. Specific modified aspects are exemplified below. Two or more aspects selected from the above embodiment and the following examples may be appropriately combined as long as they are not mutually inconsistent.

In the above embodiment (particularly steps S514 and S715), the processing load on the server 100 is reduced by performing simple development on the specified range (section, area). However, other development processes with reduced load, such as a process of thinning out frames of a RAW video at regular intervals, may also be performed.

In the above embodiment, the server 100 may adjust the processing contents of the simplified development according to the number of other users who performed cut editing or crop editing (the number m of corresponding editing information). For example, the server 100 may change the processing contents so that the more the number m of corresponding editing information is, the more processing in the development process is omitted, and thus the processing load is reduced. In addition, when the total number T of users who edit RAW videos (total number of users) is determined, the server 100 may decide whether to perform simplified development based on the ratio (m/T) of the number m of corresponding editing information to the total number T of users.

With regard to the above-described embodiment, when a specific instruction such as pausing is given to a frame that has been simply developed, or when development parameters are adjusted for a frame that has been simply developed, the server 100 may resend the normal development result of that frame to the PC 150.

With respect to the above embodiment, the section to which simplified development is applied may be clearly indicated by a specified figure such as an icon or mark within the timeline area 340 of the display screen 300.

Regarding the above-described embodiment, the server 100 may perform personal authentication of a user who accesses the server 100 using the PC 150. A plurality of users may be grouped based on a profile. For example, the server 100 may form a group of users with matching attributes or preferences. The server 100 preferably counts the number n, m of editing information indicating the execution of a predetermined editing process from among the editing information corresponding to the users included in the group. In addition, the server 100 may weight the count value based on the profile.
