  As an overall flow of the printing process, first, the digital camera 10 captures the image, the captured image data is transmitted to the print server 200, the print server 200 generates print data, and the printer 300 outputs the print data.

  As described above, when the digital camera 100 transmits image data to the print server 200, the immediate transmission mode that automatically transmits immediately after shooting, the non-immediate transmission mode 1 that automatically transmits after a certain period of time from the last shooting, There are four transmission modes, the non-immediate transmission mode 2 for automatic transmission when a certain time has elapsed since the last touch of the release button, and the manual transmission mode for manual transmission, which can be arbitrarily selected by the user. .

  In addition, it is possible to set the necessity / unnecessary setting of printing, the setting of printing conditions, the setting of handling of transmitted image data, etc. for the image data to be transmitted. Image data can be sent.

  Further, when the image data to be transmitted is RAW image data, the development conditions can be set, and the image data can be transmitted by adding information on the development conditions.

  These settings are performed using, for example, the liquid crystal monitor 30 of the digital camera 10. FIG. 6 shows an example of a setting screen displayed on the liquid crystal monitor 30. This setting screen is called, for example, by selecting the “SET UP” item from the menu screen displayed on the liquid crystal monitor 30 by pressing the MENU / OK button 36. The user performs various settings by moving the cursor with the cross button 34 in accordance with the display of the setting screen and selecting desired processing conditions for each item.

  For example, when the immediate transmission mode is selected in the “transmission mode” item, the cursor is moved to the “immediate” field and the MENU / OK button 36 is pressed. Thereby, the immediate transmission mode is selected as the transmission mode. The selected item is displayed with the background color and the character color reversed so that the setting status becomes clear (in the example shown in FIG. 6, the selected item is displayed in white).

  As shown in FIG. 6, in the digital camera 10 of the present embodiment, the items that can be set are (1) “transmission mode”, (2) “print instruction”, (3) “number of prints”, ( 4) “Image after transmission”, (5) “Image quality”, (6) “Brightness”, (7) “White balance”, (8) “Vividness”, (9) “Sharpness”, (10) Ten items of “print size” are prepared, and the user can arbitrarily set these items.

  Here, (1) “Transmission mode” item is used to set the transmission timing of the captured image data. “Immediate” is the mode for automatic transmission immediately after shooting (immediate transmission mode) and the last shooting. “Non-immediate transmission mode 1” is a mode for automatic transmission when a certain time elapses from (Non-immediate transmission mode 1) “Non-immediate 2” and “manual” which is a manual transmission mode (manual transmission mode) can be selected.

  (2) The “print instruction” item is used to set whether or not to print the captured image data, and can be selected from “ON” when printing and “OFF” when not printing. Has been.

  (3) The “Number of prints” item sets the method for specifying the number of prints when printing image data, and can be selected from “Auto”, “Auto with confirmation”, and “Manual”. Has been. Here, “automatic” is to automatically detect the number of persons in a captured image from the image data and automatically set the number of detected persons to be printed. On the other hand, “automatic with confirmation” is to determine the number of people detected automatically after confirmation by the user. If the number of automatically recognized people is incorrect, it can be corrected. “Manual” is for manually inputting the number of sheets to be printed. The specific processing of “automatic” and “automatic with confirmation” will be described in detail later.

  (4) The item “Image after transmission” sets the handling of the transmitted image data. It can be selected from “Erase” to be deleted after transmission and “Save” to be stored after transmission. Has been.

  (5) The “image quality” item sets the image quality of the image data to be recorded / transmitted. “RAW” records / transmits the captured image data as RAW image data, and low-compresses the captured image data. It is possible to select from “JPEG Hi” for compressing at a rate and recording / transmitting and “JPEG Lo” for compressing and recording / transmitting captured image data at a high compression rate.

  (6) “Brightness”, (7) “White balance”, (8) “Vividness”, and (9) “Sharpness” are items for setting development conditions for RAW image data.

  Of these, (6) “Brightness” sets the brightness of the image. “Dark” develops darker, “Normal” develops with standard brightness, and “Brighter” develops brighter. "You can choose from three.

  (7) “White balance” is used to set the white balance (light source type) of the image. “AUTO” is used for automatic adjustment, and “Sunny sky (sun mark)” is used to specify shooting outdoors in a sunny day. “Shade (cloudy mark)” that specifies shooting in the shade, “Fluorescent lamp 1 (fluorescent mark and 1)” that specifies shooting under the daylight color fluorescent lamp, and white fluorescent lamp You can select from 6 types: “Fluorescent lamp 2 (fluorescent lamp mark 2)” that specifies shooting and “bulb (bulb mark)” that specifies shooting under a light bulb or incandescent lamp. .

  (8) “Vividness” is used to set the vividness (saturation) of the image. “Low” that develops calmly and “Normal” that develops with normal vividness. You can choose from the three types of “strong” that you want to develop.

  (9) “Sharpness” is used to set the sharpness of the image. “Hard” develops the image with emphasis, “Normal” develops the image with normal sharpness, and “Soft” develops the image with softness. ”Can be selected from the three.

  (10) “Print size” is for setting the print size of the image to be transmitted. “A6” for printing to A6 size, “A5” for printing to A5 size, and “A4” for printing to A4 size. You can choose from the three.

  The user selects a desired processing condition for each item. Here, the processing conditions of each selected item are recorded in the EEPROM 118 as user setting information.

  First, processing of the digital camera 10 when “immediate transmission mode” is selected as the transmission mode will be described.

  FIG. 7 is a flowchart showing the processing procedure of the digital camera 10 when “immediate transmission mode” is selected as the transmission mode.

  First, the CPU 110 determines whether shooting has been performed (step S10). When shooting is performed, the CPU 110 determines whether communication with the print server 200 has been established after recording processing of the shot image data (step S11).

  If communication with the print server 200 has not been established, the data transmission process is stopped and the process proceeds to step S19. On the other hand, if communication with the print server 200 has been established, transmission processing of the captured image data is started (step S12).

  Thereafter, the CPU 110 determines whether or not the data transmission to the print server 200 is completed (step S13). When the CPU 110 determines that the transmission is completed, the CPU 110 collates the transmission data (step S14). That is, the data collating unit 162 collates whether the data transmitted from the digital camera 10 and the data received by the print server 200 match. Then, it is determined whether or not the collation process has been completed (step S15). When it is determined that the collation process has been completed, it is determined whether or not the transmission data and the reception data match based on the collation result of the data collation unit 162. (Step S16).

  If it is determined that the data do not match, the process returns to step S11, and the image data transmission process is executed again. On the other hand, if it is determined that the data match, the data transmission process is terminated, and it is determined whether or not to delete the transmitted image data from the storage medium 150 (step S17). This determination is made based on the user setting information recorded in the EEPROM 118. If the user has set “erase” as the handling of “image data after transmission”, the image file of the transmitted image data is stored in the storage medium. Delete from 150 (step S18). On the other hand, when the user has set “save” as the handling of “image data after transmission”, it is recorded in the storage medium 150 without being deleted.

  Thereafter, it is determined whether or not the power of the camera is turned off (step S19). If not turned off, the process returns to step S10 to repeat the above processing.

  As described above, when the “immediate transmission mode” is selected as the transmission mode, the image data is transmitted to the print server 200 immediately after shooting.

  In the above example, the captured image data is once recorded on the storage medium 150 and then transmitted. However, after the transmission process, the captured image data is recorded on the storage medium 150 according to the setting of “image data after transmission”. You may do it.

  Next, processing of the digital camera 10 when “non-immediate transmission mode 1” is selected as the transmission mode will be described.

  FIG. 8 is a flowchart showing a processing procedure of the digital camera 10 when “non-immediate transmission mode 1” is selected as the transmission mode.

  As described above, in the non-immediate transmission mode 1, when a certain period of time has elapsed since the last shooting, it is determined that the camera is in a non-shooting state, and image data transmission processing is performed.

  First, the CPU 110 determines whether or not a certain time has elapsed since the last shooting (step S20). That is, the elapsed time from the last shooting is acquired from the time measuring unit 124, and it is determined whether or not a predetermined time set in advance is exceeded. This predetermined time can be arbitrarily set by the user, and the time set by the user on the menu screen or the like is recorded in the EEPROM 118.

  If it is determined that the predetermined time has not elapsed since the last shooting, the CPU 110 determines whether or not the camera is turned off (step S22). If not, the process returns to step S20, and again. It is determined whether or not a certain time has elapsed since the last shooting. On the other hand, if it is determined that a certain time has passed since the last shooting, the CPU 110 executes a transmission process of image data (step S21).

  FIG. 9 is a flowchart showing a procedure of image data transmission processing when “non-immediate transmission mode 1” is set.

  First, the CPU 110 determines whether there is untransmitted image data (step S30). If there is no untransmitted image data, the image data transmission process is terminated, and the process returns to step S21. On the other hand, if it is determined that there is untransmitted image data, it is determined whether communication with the print server 200 has been established (step S31). If it is determined that communication with the print server 200 has not been established, the data transmission process is terminated, and the process returns to step S21. On the other hand, if it is determined that communication with the print server 200 has been established, transmission processing of the captured image data is started (step S32).

  Thereafter, the CPU 110 determines whether or not the data transmission to the print server 200 has been completed (step S33). If the CPU 110 determines that the transmission has been completed, the CPU 110 performs transmission data collation processing (step S34). Then, it is determined whether or not the collation process has been completed (step S35). When it is determined that the collation process has been completed, it is determined whether or not the transmission data and the reception data match based on the collation result of the data collation unit 162. (Step S36).

  If the data do not match, the process returns to step S31, and the image data transmission process is executed again. On the other hand, if it is determined that the data match, the data transmission process is terminated, and it is determined whether or not to delete the transmitted image data from the storage medium 150 (step S37). If the user has set “delete” as the handling of “image data after transmission” as described above, the image file of the transmitted image data is deleted from the storage medium 150 (step S38), and “save” is set. Is set, it is recorded in the storage medium 150 as it is without being deleted.

  Thereafter, the process returns to step S30, and the presence / absence of untransmitted image data is determined again, and processing according to the determination result is performed.

  As described above, in the non-immediate transmission mode 1, when a certain period of time has elapsed since the last shooting, it is determined that the camera is in a non-shooting state, and image data transmission processing is performed.

  In the above example, the transmission process is continuously executed until there is no untransmitted image data. However, if a shooting operation is performed in the middle, the transmission process is interrupted and the shooting process is performed. It may be.

  Next, processing of the digital camera 10 when “non-immediate transmission mode 2” is selected as the transmission mode will be described.

  As described above, in the “non-immediate transmission mode 2”, when a predetermined time has elapsed since the last touch of the release button 22, the image data transmission process is started assuming that the camera is in the non-shooting operation state.

  FIG. 10 is a flowchart illustrating a processing procedure of the digital camera 10 when “non-immediate transmission mode 2” is selected as the transmission mode.

  First, the CPU 110 determines whether or not a predetermined time has elapsed since the last touch of the finger with the release button 22 (step S40). That is, an elapsed time since the last touch of the finger with the release button 22 (elapsed time since the last touch of the finger was detected by the touch sensor 22A) is obtained from the time measuring unit 124, and a preset specified time is obtained. Judge whether or not it exceeds. This predetermined time can be arbitrarily set by the user, and is recorded in the EEPROM 118 set by the user on the menu screen or the like.

  If it is determined that the fixed time has not elapsed since the last time the release button 22 was touched, the CPU 110 determines whether or not the camera has been turned off (step S42). Then, it is determined again whether or not a fixed time has elapsed since the last release button 22 was touched. On the other hand, if it is determined that a certain time has passed since the last touch of the release button, the CPU 110 executes image data transmission processing (step S41).

  FIG. 11 is a flowchart illustrating a procedure of image data transmission processing when “non-immediate transmission mode 2” is set.

  First, the CPU 110 determines whether there is untransmitted image data (step S50). If there is no untransmitted image data, the image data transmission process is terminated, and the process returns to step S41. On the other hand, if it is determined that there is untransmitted image data, it is determined whether communication with the print server 200 has been established (step S51). When determining that communication with the print server 200 has not been established, the CPU 110 ends the data transmission process and returns to step S41. On the other hand, if it is determined that communication with the print server 200 has been established, transmission processing of the captured image data is started (step S52).

  Thereafter, the CPU 110 determines whether or not the data transmission to the print server 200 is completed (step S53). If it is determined that the data transmission has not been completed, the CPU 110 determines whether or not the finger touches the release button 22 based on the output from the touch sensor 22A (step S59), and the finger touches the release button 22. If it is determined that the image data has been received, the image data transmission process is stopped, and the process returns to step S41. If it is determined that the finger is not touching the release button 22, the process returns to step S53, and it is determined again whether or not the data transmission to the print server 200 is completed.

  When it is determined that the data transmission is completed, the CPU 110 performs a transmission data collation process (step S54), and determines whether the collation process is completed (step S55). If it is determined that the collation process has not been completed, the CPU 110 determines whether or not the finger touches the release button 22 based on the output from the touch sensor 22A (step S60), and the finger touches the release button 22. If it is determined that the image data has been received, the image data transmission process is stopped, and the process returns to step S41. If it is determined that the finger is not touching the release button 22, the process returns to step S55 to determine again whether or not the collation process has been completed.

  If it is determined that the collation process has been completed, the CPU 110 determines whether the transmission data and the reception data match based on the collation result of the data collation unit 162 (step S56). If the data do not match, the process returns to step S51 and the image data transmission process is executed again. On the other hand, if it is determined that the data match, the data transmission process is terminated, and it is determined whether or not to delete the transmitted image data from the storage medium 150 (step S57). If the user has set “delete” as the handling of “image data after transmission” as described above, the image file of the transmitted image data is deleted from the storage medium 150 (step S58), and “save” is set. Is set, it is recorded in the storage medium 150 as it is without being deleted.

  Thereafter, the process returns to step S50, and the presence / absence of untransmitted image data is determined again, and processing according to the determination result is performed.

  As described above, in the non-immediate transmission mode 2, when a certain period of time has elapsed since the last touch of the finger with the release button 22, it is determined that the camera is in the non-photographing state, and image data transmission processing is performed.

  Next, processing of the digital camera 10 when “manual transmission mode” is selected as the transmission mode will be described.

  FIG. 12 is a flowchart illustrating a processing procedure of the digital camera 10 when “manual transmission mode” is selected as the transmission mode.

  First, the CPU 110 determines whether or not a manual transmission instruction has been issued by the user (step S70). Here, it is assumed that the manual transmission instruction is performed on a menu screen displayed on the liquid crystal monitor 30, for example. In addition, a dedicated transmission button may be provided in the camera body 12 so that a transmission instruction is issued when the transmission button is pressed.

  If it is determined that a manual transmission instruction has been issued, the CPU 110 determines whether there is untransmitted image data (step S71). If there is no untransmitted image data, the image data transmission process is terminated, and the process proceeds to step S80. On the other hand, if it is determined that there is untransmitted image data, it is determined whether communication with the print server 200 has been established (step S72). If it is determined that communication with the print server 200 has not been established, the CPU 110 ends the data transmission process and proceeds to step S80. On the other hand, if it is determined that communication with the print server 200 has been established, image data transmission processing is started (step S73).

  Thereafter, the CPU 110 determines whether or not the data transmission to the print server 200 has been completed (step S74). If the CPU 110 determines that the transmission has been completed, the CPU 110 collates the transmission data (step S75). Then, it is determined whether or not the collation process has been completed (step S76). If it is determined that the collation process has been completed, it is determined whether or not the transmission data and the reception data match based on the collation result of the data collation unit 162. (Step S77).

  If it is determined that the data do not match, the process returns to step S72, and the image data transmission process is executed again. On the other hand, if it is determined that the data match, the data transmission process is terminated, and it is determined whether or not to delete the transmitted image data from the storage medium 150 (step S78). If the user sets “delete” as the handling of “image data after transmission” in the same manner as described above, the image file of the transmitted image data is deleted from the storage medium 150 (step S79), and “save” is set. Is set, it is recorded in the storage medium 150 as it is without being deleted.

  Thereafter, it is determined whether or not the power of the camera has been turned off (step S80). If not turned off, the process returns to step S71 to repeat the above processing.

  As described above, when “manual transmission mode” is selected as the transmission mode, untransmitted image data recorded in the storage medium 150 is transmitted to the print server 200 in response to a transmission instruction from the user.

  Next, processing of the digital camera 10 when “automatic” is selected as the method for specifying the number of prints (when the “number of prints” item is set to “automatic”) will be described.

  As described above, when the item “Number of prints” is set to “Automatic”, the number of people in the captured image is automatically detected, and the number of people detected is automatically set as the number of prints. .

  FIG. 13 is a flowchart showing the processing procedure of the digital camera 10 when “automatic” is selected as the method for specifying the number of prints.

  First, the CPU 110 determines whether shooting has been performed (step S90). If it is determined that shooting has been performed, the CPU 110 determines whether or not the item of the number of prints is set to “automatic” (step S91). This determination is made based on the user setting information recorded in the EEPROM 118. If it is determined that the item “number of prints” is set to “automatic”, the CPU 110 determines the person captured in the captured image. A detection process is performed (step S92). That is, the image data obtained by photographing is added to the image analysis unit 164, and the number m of persons appearing in the photographed image is counted. Then, the obtained number m is set as the number of prints (step S93).

  As described above, when the item “number of prints” is set to “automatic”, the number of persons in the photographed image is automatically detected, and the detected number is automatically set as the number of prints. As a result, the trouble of setting the number of prints can be saved, and the operations from shooting to printing can be performed smoothly.

  Next, the processing of the digital camera 10 when “automatic with confirmation” is selected as the method for specifying the number of prints (when the “number of prints” item is set to “automatic with confirmation”) will be described. .

  As described above, when the item “number of prints” is set to “automatic with confirmation”, the number of persons automatically detected from the captured image can be corrected as necessary after the user confirms it.

  FIG. 14 is a flowchart showing a processing procedure of the digital camera 10 when “automatic with confirmation” is selected as the method for specifying the number of prints.

  First, the CPU 110 determines whether shooting has been performed (step S100). If it is determined that shooting has been performed, the CPU 110 determines whether or not the item for the number of prints is set to “auto with confirmation” (step S101). This determination is made based on the user setting information recorded in the EEPROM 118. If it is determined that the item “Number of prints” is set to “Auto with confirmation”, the CPU 110 displays the person shown in the photographed image. Is detected (step S102). Then, the detected number m is displayed on the liquid crystal monitor 30 as the number of prints (step S103). At this time, the CPU 110 also displays the captured image on the liquid crystal monitor at the same time. For example, the number m of prints is displayed in the lower right corner of the photographed image. The user checks the number m of prints displayed on the liquid crystal monitor 30 and confirms whether correction is necessary. If no correction is required, the user presses the MENU / OK button 36 to determine the number of prints.

  On the other hand, if correction is required, the number of prints is corrected using the upper and lower keys of the cross button 34. The CPU 110 determines whether or not the number of prints has been corrected by pressing the up key or the down key of the cross button 34 (step S104). The number of prints increases when the up key of the cross button 34 is pressed (increases in accordance with the number of times of pressing), and decreases when the down key is pressed in (increases in accordance with the number of times of pressing). When the CPU 110 determines that the upper key or the lower key of the cross button 34 has been pressed, the CPU 110 corrects the number m of prints according to the operation amount. At this time, the display on the liquid crystal monitor 30 is also corrected.

  As described above, when it is necessary to correct the number m of prints, the correction is made by using the upper key and the lower key of the cross button 34, and after the correction, the MENU / OK button 36 is pressed to confirm. When the number of prints is determined, CPU 110 sets the determined number of prints (step S106).

  As described above, when the item “number of prints” is set to “automatic with confirmation”, the number of persons automatically detected from the captured image can be corrected as necessary after the user confirms it. Thereby, even if the result of automatic recognition is wrong, it can correct easily and the work from photography to printing can be advanced smoothly.

  When the item “number of prints” is set to “manual”, the number of prints is input manually. In this case, the number of prints may be input immediately after shooting, or the number of prints may be input during reproduction of recorded image data.

  When inputting the number of prints immediately after shooting, for example, when shooting is performed, a screen for inputting the number of prints is automatically displayed on the liquid crystal monitor 30. In this input screen, the number of prints (initial value 0) is displayed in the lower right corner of the photographed image in the same manner as described above, and the number of prints is input by increasing / decreasing the value with the up and down keys of the cross button 34.

  In addition, when inputting the number of prints during reproduction of photographed image data, for example, a print number input screen is called from the reproduction menu. In this input screen, the number of prints (initial value 0) is displayed in the lower right corner of the reproduced image in the same manner as described above, and the number of prints is input by increasing / decreasing the value with the up and down keys of the cross button 34.

  The information on the number of prints input in this way is recorded, for example, in the header portion of the image file. When the image data is transmitted, the image data is transmitted to the print server 200 together with the image data. Other print condition information, RAW image data development condition information, print instruction information, and the like are also recorded in the header portion of the image file, and are transmitted to the print server 200 together with the image data when the image data is transmitted. Note that these pieces of information may be recorded in a separate file from the image data and transmitted simultaneously with the transmission of the image data.

  Next, the operation of the print server 200 that processes the image data transmitted from the digital camera 10 will be described.

  FIG. 15 is a flowchart showing the procedure of the processing operation of the print server 200.

  As described above, the image data transmitted from the digital camera 10 is received by the communication unit 226 and temporarily stored in the first data storage unit 216. The CPU 210 of the print server 200 determines whether there is image data in the first data storage unit 216 (step S110).

  When determining that there is image data in the first data storage unit 216, the CPU 210 determines whether there is a print instruction for the image data (step S111). That is, it is determined whether the setting of the print instruction attached to the image data is ON.

  If it is determined that the print instruction is set to OFF (including the case where there is no print instruction information), the CPU 210 proceeds to step S124 and performs recording processing of the received image data (step S124). That is, the image data in the first data storage unit 216 is moved to the second data storage unit 218 without being printed as it is (move to the second data storage unit 218 without generating print data).

  On the other hand, if it is determined that the print instruction is set to ON, the CPU 210 determines whether a print condition is set for the image data (step S112). That is, it is determined whether the number of prints and the print size are specified for the image data. If it is determined that the print condition is not set, the CPU 110 reads the default print condition stored in the development / print condition storage unit 224 and sets it as the print condition of the received image data.

  Thereafter, the CPU 110 determines whether the received image data is RAW image data (step S114). If the CPU 110 determines that the received image data is not RAW image data, the CPU 110 proceeds to step S118 and performs print data generation processing (step S118). That is, the received image data is added to the print data generation unit 220 to generate print data.

  On the other hand, when determining that the received image data is RAW image data, the CPU 210 determines whether a development condition is attached to the RAW image data (step S115). If it is determined that the development condition is not attached, the CPU 110 reads a predetermined development condition stored in the development / print condition storage unit 224 and sets it as the development condition of the received RAW image data (step S116). . Then, development processing is executed according to the set development conditions (step S117). That is, the set development condition and RAW image data are added to the RAW image data development unit 222, and the RAW image data is developed according to the set development condition.

  The developed image data is temporarily stored in the first data storage unit 216 under the control of the CPU 210 and then added to the print data generation unit 220. The print data generation unit 220 generates print data based on the input image data under the control of the CPU 210 (step S118). The generated print data is stored in the first data storage unit 216.

  Thereafter, the CPU 210 determines whether or not the print mode is set to “automatic print mode” (step S119).

  Here, the “automatic print mode” is a mode for automatically printing the received image data regardless of the print instruction from the user. A “manual print mode” for printing after waiting for a print instruction can be selected alternatively.

  The print mode is set using the display unit 230 and the operation unit 228, for example. In other words, a print mode selection screen is displayed on the display unit 230, and the user selects either the “automatic print mode” or the “manual print mode” by the operation unit 228. Information on the selected print mode is recorded in, for example, an EEPROM (not shown).

  If the CPU 210 determines that the print mode is not set to “automatic print mode”, the CPU 210 determines whether or not there is a print instruction from the user (step S120). Note that the print instruction is input from the operation unit 228, and the CPU 210 determines whether or not there is a print instruction from the operation unit 228.

  On the other hand, if it is determined that the print mode is set to “automatic print mode”, or if it is determined that a print instruction is input under “manual print mode”, the CPU 210 establishes communication with the printer 300. It is determined whether or not (step S121). When it is determined that communication with the printer 300 is established, the print data stored in the first data storage unit 216 is transmitted to the printer 300 (step S122), and an image of the set printer size is set. The number of sheets is printed on the printer 300.

  Thereafter, the CPU 210 determines whether the printing is completed (step S123). If the CPU 210 determines that the printing is completed, the CPU 210 moves the image data stored in the first data storage unit 216 to the second data storage unit 218 ( Step S124). Then, after the data movement is completed, it is determined whether or not the power of the camera has been turned off (step S125). If not, the process returns to step S110 and the above processing is repeated.

  As described above, when there is a print instruction for the image data received from the digital camera 10, the print server 200 generates print data based on the received image data, performs print processing, and then executes the second data storage unit. Record at 218. On the other hand, if there is no print instruction for the image data received from the digital camera 10, the print data is not recorded, but is recorded in the second data storage unit 218 as it is.

  Thus, by recording image data in the second data storage unit 218 regardless of whether or not there is a print instruction, it is possible to effectively prevent the loss and destruction of the image data. Further, by storing the original image data in the second data storage unit 218, it is possible to cope with the case where the image is corrected after printing.

  In addition, since the print server 200 includes the RAW image data development unit 222, even when RAW image data is transmitted from the digital camera 10, printing can be performed without any problem, and image quality adjustment is necessary. Even in this case, degradation of image quality can be minimized. Since RAW image data has different development methods depending on the type of camera, it is assumed that the RAW image data developing unit 222 can develop RAW image data of various cameras.

  In the present embodiment, when there is a print instruction in the image data, the print data is generated from the image data, the generated print data is output to the printer, and then the image data is transferred from the first data storage unit 216 to the second data. Although the image data is moved to the data storage unit 218, the timing of moving the image data to the second data storage unit 218 is not limited to this. For example, after the print data is generated, the data may be moved from the first data storage unit 216 to the second data storage unit 218, or may be moved to the second data storage unit 218 when the print data generation is started. Alternatively, image data may be added from the first data storage unit 216 to the print data generation unit 220 and moved to the second data storage unit 218 at the same time.

  In the above embodiment, when no print condition is set in the image data received from the digital camera 10, the image is printed according to the default print condition stored in the development / print condition storage unit 224. However, when the print condition is not set in the image data received from the digital camera 10, the user may manually set the print condition using the display unit 230 and the operation unit 228.

  Similarly, when the development condition is not set in the RAW image data received from the digital camera 10, the user may manually set the development condition using the display unit 230 and the operation unit 228.

  The default print condition and the default development condition stored in the development / print condition storage unit 224 may be arbitrarily set by the user.

  When image data is printed, the print condition of the printed image data may be stored in the development / print condition storage unit 224 as a default print condition. In this case, each time printing is performed, a new print condition is recorded in the development / print condition storage unit 224. Therefore, if no print condition is set for the received image data, printing is performed under the same print condition as the print condition of the last printed image data.

  Similarly, when the RAW image data is developed, the development condition of the developed RAW image data may be stored in the development / print condition storage unit 224 as a predetermined development condition. In this case as well, new development conditions are recorded in the development / print condition storage unit 224 each time development processing is performed as described above. Therefore, when the development condition is not set for the received RAW image data, the development is performed under the same development condition as the development condition of the last developed RAW image data.

  In this embodiment, the print server and the printer are configured separately, but the function of the print server may be incorporated in the printer and configured integrally.

  In this embodiment, a wireless communication unit is used for communication between the printer 300 and the print server 200, but a wired communication unit may be used. Similarly, a wired communication unit may be used for communication between the digital camera 10 and the print server 200.

  Further, in this embodiment, the communication means is incorporated in each of the digital camera 10, the print server 200, and the printer 300, but an external communication means may be used.

  Further, as described above, the communication means is not particularly limited, and for example, a wireless LAN method, a Bluetooth method, an infrared method, or the like can be applied. Therefore, communication may be performed using a public line, and the digital camera 10 may be configured with a camera-equipped mobile phone.
