Furthermore, as another method, the main body 12 may acquire such a program via a communication line.

  FIG. 5 is a flowchart showing an example of the operation of the image output apparatus 10. First, the operation when a new image is displayed on the display 14 or when another image different from the currently displayed image is displayed on the display 14 will be described. As a specific example, this flowchart starts when the screen input / output unit 110 receives an input from the user to display an image identified by the image ID “G001”. Further, it is assumed that the identification information storage unit 150 stores the information shown in FIG. 4 at the start of this flowchart.

  The parameter acquisition unit 120 acquires the parameter ID “P001” and the parameter value “G001” from the screen input / output unit 110 (S100). Here, the parameter acquisition unit 120 also acquires a parameter ID other than the parameter ID “P001” and the value (initial value) of the parameter (same step).

  The parameter storage unit 130 stores the parameter value “G001” acquired by the parameter acquisition unit 120 in association with the parameter ID “P001” (S110). Here, the parameter storage unit 130 stores parameter values of parameter IDs other than the parameter ID “P001” in association with the respective parameter IDs (same step).

  The process specifying unit 140 specifies an image processing unit that uses the newly changed parameter (S300). Specifically, the process specifying unit 140 specifies the read processing unit 100 using the parameter ID “P001” (same step). This step will be described in detail with reference to FIG.

  The process specifying unit 140 determines whether the specified image processing unit is the read processing unit 100 (S120). In this case, the processing specifying unit 140 refers to the information regarding the order of image processing set in association with the image processing ID to be held, and the specified image processing unit is the read processing unit 100 whose order is first. Determine whether or not. In this specific example, the process specifying unit 140 determines that the read processing unit 100 whose order is first is specified (S120: Yes). In this case, the processing specifying unit 140 transmits an instruction to the image processing to the reading processing unit 100 together with the parameters stored in the parameter storage unit 130. Based on the instruction and parameter, the read processing unit 100 reads the image data identified by the image ID “G001” stored in the image storage unit 160 (S130). The read processing unit 100 caches the read image data in the read cache unit 200 (S140). Then, the read processing unit 100 instructs the resize processing unit 102 having the next order based on the information of the order that the reading processing unit 100 has (S190).

  When receiving an instruction from the read processing unit 100, the resize processing unit 102 acquires the image data cached in the read cache unit 200 via the read processing unit 100 (S150). The resizing processing unit 102 performs resizing processing based on the acquired image data and the values of a plurality of newly acquired parameters stored in the parameter storage unit 130 (S160). The resizing processing unit 102 caches the resized image data in the resizing cache unit 202 (S170). Next, the resizing processing unit 102 determines whether or not it is the last process in the image processing unit 190 (S180). In this case, the resizing processing unit 102 can identify the color correction processing unit 104 in the next order based on the information of the order that it has, and therefore determines that its processing is not the last processing ( S180: No). The resizing processing unit 102 instructs the color correction processing unit 104 in the next order to perform processing (S190).

  When receiving an instruction from the resize processing unit 102, the color correction processing unit 104 acquires the image data cached in the resize cache unit 202 via the resize processing unit 102 (S150). The color correction processing unit 104 performs color correction processing based on the acquired image data and the values of a plurality of newly acquired parameters stored in the parameter storage unit 130 (S160). The color correction processing unit 104 caches the image data subjected to the color correction processing in the color correction cache unit 204 (S170). Next, the color correction processing unit 104 determines whether or not it is the last process in the image processing unit 190 (S180). In this case, the color correction processing unit 104 can identify the trimming processing unit 106 that is in the next order based on the information on the order that the color correction processing unit 104 has. S180: No). Then, the color correction processing unit 104 instructs the trimming processing unit 106 in the next order to perform processing (S190).

  When receiving an instruction from the color correction processing unit 104, the trimming processing unit 106 acquires the image data cached in the color correction cache unit 204 via the color correction processing unit 104 (S150). The trimming processing unit 106 performs a trimming process based on the acquired image data and the values of a plurality of newly acquired parameters stored in the parameter storage unit 130 (S160). The trimming processing unit 106 caches the trimmed image data in the trimming cache unit 206 (S170). Next, the trimming processing unit 106 determines whether it is the last process in the image processing unit 190 (S180). In this case, the trimming processing unit 106 determines that its own process is the last process based on the order information that it has (S180: Yes). Then, the trimming processing unit 106 transfers the image data cached in the trimming cache unit 206 to the screen input / output unit 110 (S200). The parameter storage unit 130 also transcribes the parameter value acquired this time to the parameter value acquired last time. The screen input / output unit 110 displays the image data received from the trimming processing unit 106 on the display 14. And this flowchart is complete | finished.

  Next, an operation when image processing is performed on an image displayed on the display 14 will be described. As a specific example, this flowchart shows a user that the screen input / output unit 110 should perform color correction processing, for example, white balance, at the end of the above flow (while displaying image data identified by the image ID “G001”). Start by receiving input from. It is assumed that the white balance is a parameter ID “P020” and an input indicating that the white balance is “1 (ON)” from the user is received.

  The parameter acquisition unit 120 acquires the parameter ID “P020” and the parameter value “1” from the screen input / output unit 110 (S100). Here, the parameter acquisition unit 120 also acquires a parameter ID other than the parameter ID “P020” (for example, the parameter ID “P001”) and the parameter value (for example, the parameter value “G001”, etc.). Step).

  The parameter storage unit 130 stores the parameter value “1” acquired by the parameter acquisition unit 120 in association with the parameter ID “P020” (S110). Here, the parameter storage unit 130 stores parameter values of parameter IDs other than the parameter ID “P001” in association with the respective parameter IDs (same step).

  The process specifying unit 140 specifies an image processing unit that uses the newly changed parameter (S300). Specifically, the process specifying unit 140 specifies the color correction processing unit 104 using the parameter ID “P020” (same step). This step will be described in detail with reference to FIG.

  The process specifying unit 140 determines whether the specified image processing unit is the read processing unit 100 (S120). In the specific example, the process specifying unit 140 determines that the specified image processing unit is not the read processing unit 100 (S120: No). In this case, the process specifying unit 140 instructs the color correction processing unit 104, which is the image process specified in step S300, to perform image processing.

  When receiving the above instruction, the color correction processing unit 104 identifies the resize processing unit 102 as the previous image processing unit based on the information of the order that the color correction processing unit 104 has, and through the resize processing unit 102, Image data cached in the resize cache unit 202 is acquired (S150). The color correction processing unit 104 performs color correction processing based on the acquired image data and the values of a plurality of newly acquired parameters stored in the parameter storage unit 130 (S160). The color correction processing unit 104 caches the image data subjected to the color correction processing in the color correction cache unit 204 (S170). The color correction processing unit 104 determines that its own processing is not the last processing (S180: No), and instructs the trimming processing unit 106 in the next order to perform processing (S190). Since the operation is the same as that in the case of selecting an image to be displayed on the display 14, the description thereof is omitted. Thereby, the calculation amount required for image processing can be reduced, and an image can be displayed quickly.

  When the image processing unit is specified by the process specifying unit 140 in step S300, the image processing unit specified by the process specifying unit 140 and the image processing unit after the order are currently cached. The existing image data may be discarded prior to the operation in step S150. As a result, the memory area cached with the image data that does not contribute to the reduction in the calculation amount is released, so that the memory area can be saved.

  FIG. 6 is an example of a flowchart of the operation in step S300 in the process specifying unit 140. Note that the processing specifying unit 140 holds information regarding the order of image processing set in association with the image processing ID.

  First, the process specifying unit 140 acquires the values of a plurality of newly acquired parameters and the values of previously acquired parameters, compares them, and specifies the parameter ID of the newly changed parameter. (S310). For example, when a new image is displayed on the display 14 or when another image different from the currently displayed image is displayed on the display 14, at least the parameter ID (parameter ID “P001”) related to the image ID, Since the value of the parameter acquired last time stored in the parameter storage unit 130 and the value of the parameter stored in the parameter storage unit 130 in step S110 shown in FIG. 5 do not match, the parameter ID of the newly changed parameter At least the parameter ID “P001” is specified. Similarly, for example, when color correction processing (white balance) is performed on an image displayed on the display 14, as shown in FIG. 3, at least a parameter ID (parameter ID “P020”) relating to white balance is provided. Since the value of the parameter acquired last time stored in the parameter storage unit 130 and the value of the parameter stored in the parameter storage unit 130 in step S110 shown in FIG. 5 do not match, the parameter ID of the newly changed parameter At least the parameter ID “P020” is specified. The process specifying unit 140 receives a notification from the parameter acquisition unit 120 or the parameter storage unit 130, or monitors the parameter storage unit 130 by itself (refers to it in a short cycle), thereby causing the parameter acquisition unit 120 to perform a new process. When the parameter value is acquired, the parameter ID of the newly changed parameter is specified.

  The process specifying unit 140 refers to the identification information storage unit 150 and specifies an image process ID that uses the newly changed parameter (S320). In step S310, when specifying at least the parameter ID “P001”, the processing specifying unit 140 refers to the identification information storage unit 150 and uses at least the image processing ID “S01” as the image processing ID using the newly changed parameter. Is specified.

  Next, the process specifying unit 140 determines whether a plurality of image process IDs have been specified (S330). In step S330, when determining that the plurality of image processing IDs are not specified (S330: No), the processing specifying unit 140 specifies the image processing unit identified by the specified image processing ID (S340). On the other hand, in step S330, when the process specifying unit 140 determines that a plurality of image processing IDs have been acquired (S330: Yes), the set order of image processing is the most among the acquired plurality of image processing IDs. The image processing unit identified by the previous image processing ID is specified (S350). The process specifying unit 140 instructs the image processing unit specified in step S340 or step S350 to perform the process (S360). And this flowchart is complete | finished.

  In the flowcharts shown in FIGS. 5 and 6, the case of displaying on the display 14 has been described, but the same applies to the case of outputting to the printer 24. That is, the reading processing unit 100, the resizing processing unit 102, the color correction processing unit 104, and the trimming processing unit 106 perform processing on image data for printing in addition to processing on image data for display. For example, each of the reading processing unit 100, the resizing processing unit 102, the color correction processing unit 104, and the trimming processing unit 106 may include a processing unit for display image data and a processing unit for print image data. Good. Similarly, the read cache unit 200, the resize cache unit 202, the color correction cache unit 204, and the trimming cache unit 206 cache image data for printing in addition to caching image data for display. For example, each of the read cache unit 200, the resize cache unit 202, the color correction cache unit 204, and the trimming cache unit 206 may include a cache unit for display image data and a cache unit for print image data. Good.

  As a result, when a new parameter relating to the printing image data is acquired, the processing specifying unit 140 specifies an image processing unit that performs processing on the printing image data using the new parameter. The image processing unit that is one order earlier than the identified image processing unit delivers the cached image data for printing to the image processing unit identified by the process identifying unit 140. The image processing unit specified by the processing specifying unit 140 and the image processing unit having the subsequent order are based on the received image data for printing and the parameter values stored in the parameter storage unit 130 according to the order. The image data for printing that has undergone image processing is output. In particular, when printing is performed based on the same parameter values as the previous time, the print output unit 170 obtains and prints image data for printing cached in the trimming cache unit 206 via the trimming processing unit 106. Generate data. In this case, the reading processing unit 100, the resizing processing unit 102, and the color correction processing unit 104 do not perform reading processing, resizing processing, and color correction processing on the image data for printing. Therefore, as in the case of displaying an image quickly, the amount of calculation required for image processing can be further reduced, and the image can be printed quickly.

  As described above, according to the present embodiment, the amount of calculation required for image processing can be reduced, and an image can be displayed or printed quickly. Note that the resize cache unit 202 may be divided for each parameter related to the resize processing unit 102. When the resize cache unit 202 is divided for each parameter related to the resize processing unit 102, the resize processing unit 102 stores the image data subjected to the resize processing for each parameter related to the resize processing unit 102 in the resize cache unit 202. Cache. Thereby, when the order of processing for each parameter related to the resizing processing unit 102 is set, the calculation amount required for image processing can be further reduced, and the image can be displayed or printed quickly. The color correction processing unit 104 and the trimming processing unit 106 may be similar.

  In this embodiment, the identification information storage unit 150 sets the image processing ID values in ascending order according to the set order of image processing as shown in FIG. The image processing order set for the identified image processing unit is acquired by referring to the value of the image processing ID that is in ascending order without holding information regarding the order of the image processing set in association with the ID. Also good.

  Further, in the present embodiment, the process specifying unit 140 compares the values of a plurality of newly acquired parameters with the previously acquired parameter values and acquires the parameter ID of the newly changed parameter. Thus, the image processing ID using the newly changed parameter is acquired, but the present invention is not limited to this. As another example, the parameter acquisition unit 120 acquires only the parameter ID of the newly changed parameter and the value of the parameter ID. The parameter storage unit 130 stores the newly changed parameter value acquired by the parameter acquisition unit 120 in association with the parameter ID, and sets a flag in the parameter ID. The process specifying unit 140 may acquire an image processing ID using a newly changed parameter by referring to the flag of the parameter storage unit 130.

  In the present embodiment, the correspondence between one parameter and the image processing unit using the parameter is stored in the identification information storage unit 150, but is not limited thereto. As another example, the value of the image processing ID may be included in the value of the parameter ID. Specifically, for example, the value of the parameter ID “P001” may be the parameter ID “S01_P001” including the image processing unit “S01” using the parameter.

  In addition, the parameter classification acquired by the parameter acquisition unit 120 from the screen input / output unit 110 may be different from the classification of the parameter to be stored in the parameter storage unit 130. In this case, the parameter acquisition unit 120 holds information that associates the classification of parameters acquired from the screen input / output unit 110 with the classification of parameters to be stored in the parameter storage unit 130, and the screen input / output unit When parameters are acquired from 110, parameters based on classification of parameters to be stored in the parameter storage unit 130 may be acquired by referring to the associated information. For example, when the screen input / output unit 110 receives an input indicating that the image data circumscribing and displaying the image frame should be displayed inscribed in the image frame, the parameter acquisition unit 120 sets the parameter related to the image frame. And a parameter for displaying the image data inscribed in the image frame is acquired from the screen input / output unit 110. The parameter acquisition unit 120 uses a parameter ID used for processing of the resizing processing unit 102 as a classification of parameters to be stored in the parameter storage unit 130 based on the information acquired from the screen input / output unit 110 and the above-described information. To get. The parameter acquisition unit 120 acquires the parameter ID by calculating the parameter value based on the parameter acquired from the screen input / output unit 110.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment.
