Description

  The present invention relates to a photographic processing apparatus for correcting and outputting digital image data.

In an analog photographic processing apparatus that prints out a photographic image recorded on a film, a process called pre-judge is performed in order to produce a photographic print with stable quality. In the pre-judge process, monitor digital image data is created for a photographic image recorded on each frame of the film, and the digital image data is displayed on the monitor. Then, the operator confirms the digital image data displayed on the monitor, and the image correction processing is performed by the operator inputting correction items such as color tone correction and the correction amount so as to obtain an appropriate print finish. If the image displayed on the monitor after the correction process is unsatisfactory and you want to redo the correction from the beginning, the operator is performing input work to return the correction amount to the initial state for all correction items that have been performed so far .

  With the recent spread of digital cameras and camera-equipped mobile phones, digital photo processing apparatuses that perform print output processing of digital image data photographed by these cameras have also become popular. Similar to the analog photo processing device described above, pre-judge processing is also performed in the digital photo processing device.

  However, in the pre-judge process of the digital photo processing apparatus, the correction target items are remarkably increased compared to the pre-judge process of the analog photo process apparatus. For this reason, if you are dissatisfied with the image displayed on the monitor and want to redo the correction from the beginning, the operator's input work to return the correction amount to the initial state for all correction items performed so far is very troublesome. It has become. The more items to be corrected, the more time is required to return to the initial state. In addition, time for checking whether or not to forget to return is wasted. If there is a function to quickly and reliably return to the initial state, it will be easier to use.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a photographic processing apparatus capable of improving the efficiency of correction processing.

  A photographic processing apparatus according to the present invention is a device that performs digital image data correction processing while displaying digital image data to be printed on a photographic print, on each of the digital image data displayed on the monitor. Means (a) for storing correction items and correction amounts, selection of digital image data desired to be corrected among the digital image data displayed on the monitor, and correction items and correction amounts for the selected digital image data Means (b) for prompting the operator to input, and correction items and correction amounts for the digital image data selected as correction target by the operator among the correction items and correction amounts stored in the means (a). , Means for updating based on the correction item and the correction amount input by the operator ( ), And means (d) for correcting the digital image data displayed on the monitor based on the correction items and correction amounts stored in the means (a), and the monitor. In response to the input of the correction cancellation instruction by the operator (e) for prompting the operator to select the digital image data desired to be corrected from the digital image data and to input the correction cancellation instruction, Means (c) for updating the correction amounts of all correction items for the digital image data selected as correction cancellation targets by the operator among the correction items and correction amounts stored in the means (a) to initial values; Prepare.

  Compared to analog photo processors that have few correction items and correction inputs, current digital photo processors have a very large number of image correction items. For this reason, when the correction state is not expected, it may be more efficient to restore the correction amounts of all the correction items to the reference set values (initial values) and perform correction again. In the photographic processing apparatus of the present invention, when an instruction to cancel correction is input by the operator, the correction amounts of all correction items for the digital image data selected by the operator as the correction cancellation target are automatically returned to the initial values. Therefore, it is possible to improve the correction process in digital photo printing.

  A photo processing apparatus according to an embodiment of the present invention is a digital photo processing apparatus that performs print output processing of digital image data taken by a digital camera or a camera-equipped mobile phone. In this apparatus, in order to produce a photographic print with stable quality, the print output process is performed after correcting the digital image data to be printed. Correction processing is performed in two stages, master correction and manual correction. First, a master correction process is performed on digital image data to be printed. In the master correction process, correction conditions are set in advance according to shooting conditions such as the camera model, and the digital image data is corrected according to the correction conditions. Next, manual correction processing is performed on the digital image data after master correction. In manual correction processing, the digital image data after master correction is displayed on the monitor, the operator checks the digital image data displayed on the monitor, and correction items such as color correction and the correction amount are set so that an appropriate print finish is obtained. The image correction process is performed by adjustment by the operator.

  FIG. 1 shows a configuration of a portion related to the above-described manual correction processing in the digital photo processing apparatus according to the embodiment of the present invention. The part illustrated in FIG. 1 includes a storage device 10, an input device 20, a correction control unit 30, a correction processing unit 40, and a monitor 50.

  The storage device 10 stores correction items and correction amounts for each digital image data after master correction. Here, digital image data after master correction is assumed to be image data 1 to 4. Therefore, the storage device 10 stores correction items Y, M,... And correction amounts for the image data 1 to 4. The correction items include not only the color tones Y, M, C, and D, but also correction items unique to digital image data, such as contrast, sharpness, magnification, and tilt. Here, the correction state of the digital image data after the master correction (the manual correction process is not performed) is set as a reference state, and the difference from the reference state is set as a correction amount. Therefore, the correction amount of each correction item after the master correction (the manual correction process is not performed) is 0, which is the initial value (reference value).

  The input device 20 is a keyboard, a mouse, or the like, and an operator operates these to perform various input processes.

  The correction control unit 30 sets the correction item and the correction amount for the digital image data selected as the correction desired object by the operator among the correction item and the correction amount stored in the storage device 10, the correction item input by the operator, Update based on the correction amount. Further, the correction control unit 30 responds to the input of the correction cancellation instruction by the operator, and all of the digital image data selected as the correction cancellation target by the operator among the correction items and correction amounts stored in the storage device 10. The correction amount of the correction item is updated to the initial value.

  The correction processing unit 40 performs correction processing of the digital image data selected as the correction target by the operator based on the correction item and the correction amount stored in the storage device 10.

  The monitor 50 displays digital image data (digital image data after manual correction) after the correction processing by the correction processing unit 40 is performed. The monitor 50 also displays a check box that prompts the operator to select digital image data desired to be corrected from among the displayed digital image data and input correction items and correction amounts for the selected digital image data. Is done. In addition, a check box or the like that prompts the operator to select digital image data desired to be canceled out of the digital image data displayed on the monitor 50 and to input an instruction to cancel the correction is also displayed.

  Next, the flow of manual correction processing performed in the digital photo processing apparatus according to the present embodiment will be described with reference to the flowchart of FIG. In the following description, it is assumed that digital image data 1 to 4 are print output targets.

  Digital image data 1 to 4 subjected to the master correction is given to the correction processing unit 40. The storage device 10 stores correction items Y, M,... And correction amounts for the digital image data 1 to 4. The initial value (reference value) 0 is set for the correction amount of each correction item.

  Here, the digital image data and the correction item to be corrected are not selected, and the correction value of each correction item is set to the initial value 0. Therefore, the correction processing unit 40 receives the given digital image. The data 1 to 4 are output to the monitor 50 without being subjected to correction processing (ST101 to ST102). As a result, a screen as shown in FIG. As shown in FIG. 3, the monitor 50 has digital image data 1 to 4, selection check boxes for each of the digital image data 1 to 4, correction items Y, M, C, and D, correction amounts, and correction amounts. A control box, a “select all” box, a “cancel correction” box, and a “manual correction end” box are displayed.

  The operator confirms the digital image data 1 to 4 displayed on the monitor 50 and performs correction processing on the digital image data determined to be correction processing as follows.

  First, a selection check box corresponding to digital image data determined to require correction processing (the same applies to one or more digital images) is clicked with the mouse (ST104). Here, it is assumed that the selection check box of the digital image data 1 is clicked. Next, the “+” or “−” box corresponding to the correction item determined to be corrected among the correction items for the digital image data 1 is clicked (ST104). Click the “-” box to decrease the box. The degree of increase / decrease in the correction amount is proportional to the number of clicks. When it is determined that correction is necessary for all the digital image data 1 to 4, a “select all” box is clicked. In response to this, “LE” is displayed in the selection check boxes for all the image data.

  To correct contrast, sharpness, magnification, inclination, etc., which are correction items specific to digital image data, click the digital image data 1 displayed on the monitor 50. As a result, the display on the monitor 50 is switched to the one-screen display of the digital image data 1 as shown in FIG. In this screen, the enlarged digital image data 1 and the correction items Y, M, C, D, contrast, sharpness, magnification, inclination, etc., and the correction amount and correction amount for the digital image data 1 are controlled. , A “Cancel correction” box is displayed. In this screen as well, the operator clicks the “+” or “−” box corresponding to the correction item determined to be corrected among the correction items (ST104).

  Based on the click information by the operator, the correction control unit 30 updates the correction item and the correction amount for the digital image data 1 stored in the storage device 10 based on the correction item and the correction amount input by the operator ( ST105).

  Based on the updated correction amount, the correction processing unit 40 corrects the digital image data 1 and outputs it to the monitor 50.

  When it can be determined that the digital image data 1 to 4 displayed on the monitor 50 have a sufficiently appropriate print finish, the operator clicks the “manual correction end processing” button (YES in ST103). As a result, the digital image data 1 to 4 in the corrected state currently displayed on the monitor 50 are printed.

  On the other hand, if the image data displayed on the monitor 50 is unsatisfactory and the user wants to redo the correction from the beginning, the user selects a check box for selecting the digital image data to be redone (same for one or more). Next, the “correction release” box is clicked (ST106).

  Based on the click information by the operator, the correction control unit 30 sets the correction amounts of all the correction items for the digital image data selected as the correction cancellation target by the operator among the correction items and correction amounts stored in the storage device 10. The initial value is updated to 0 (ST107).

  Based on the updated correction amount, the correction processing unit 40 corrects the digital image data 1 and outputs it to the monitor 50 (ST101). As a result, the digital image data selected as the correction cancellation target is displayed on the monitor 50 in a state before the manual correction process is performed. Then, the operator again performs manual correction processing on the digital image data.

  Thus, in the present embodiment, when the “correction cancellation” button displayed on the monitor 50 is clicked by the operator, the correction amounts of all the correction items for the digital image data selected by the operator are returned to the initial values. ing. As a result, it is possible to save the trouble of returning all correction items to the uncorrected state each time manual correction is performed again, and to quickly and surely return to the uncorrected state. In addition, troubles such as forgetting to return the correction value can be prevented. In this way, it is possible to increase the efficiency of correction processing in digital photo printing.

  Further, desired image data is selected from a plurality of digital image data displayed on the monitor 50, and the correction amount of the correction item for the selected image data is returned to the initial value. This is effective in a digital photo processing apparatus that performs print output processing of digital image data taken by a digital camera or a camera-equipped mobile phone. This is because there is only one negative film and it is difficult to think about long-term use, and since there are many cases where the same camera is used, correction information for image data recorded on the same film does not change much. Therefore, in the manual correction processing in the analog photographic processing apparatus that prints out the photographic image recorded on the film, there is no problem as long as the correction can be canceled for all the image data at once. On the other hand, in digital cameras and camera-equipped mobile phones, a memory card corresponding to a negative film is versatile and can be used with different cameras and has a large storage capacity. For this reason, digital image data with different shooting conditions are mixed in one memory card, and the tendency of correction information varies among these image data. Therefore, in manual correction processing in a digital photo processing apparatus, it is highly effective to have a function of selecting only image data having a tendency of correction information and canceling correction.

  When a correction cancellation instruction is input by the operator, the photo processing apparatus of the present invention automatically returns the correction amounts of all correction items for the digital image data selected by the operator as the correction cancellation target to the initial values. Since it has a function, an efficient correction process in digital photo printing can be realized.
