[0015]
The reference person who creates the reference person color density correction data is preferably the owner of the store where the photo processing apparatus is installed.
[0016]
Next, an example of finishing a print by the photo processing apparatus having the above configuration will be described with reference to a flowchart.
[0017]
First, the reference person color density correction data creation function 54 and the worker-specific color density correction data creation function 55 allow the reference person and each operator who performs the printing process to use the reference person color density respectively using the film provided with the reference image. Correction data and color density correction data for each worker are created, and the correction data is registered in the correction value data registration function 56.
[0018]
That is, first, the reference color density correction data is created by the owner of the store serving as the reference person. As shown in the flowchart of FIG. 3, first, the reference image of the reference film is scanned (via the scanner 2). Step 101).
[0019]
Then, the yellow correction key 6f, the magenta correction key 6g, the cyan correction key 6h, the numerical value input key 6i, etc. of the keyboard 6 are operated to arbitrarily correct the color density of the scanned image (step 102), and then print processing is performed. (Step 103).
[0020]
Next, the owner confirms the quality of the finished print (step 104). If the quality standard is not cleared, the process returns to step 102. If it is determined that the quality standard is cleared, The reference person color density correction data is registered in the correction data registration function 56 (step 105).
[0021]
Further, color density correction data for each worker is created for each worker, and will be described with reference to the flowchart shown in FIG. 4. First, after inputting the name of the worker (step 200), the scanner 2 is operated. The reference image of the reference film is scanned through (step 201).
[0022]
Then, the yellow correction key 6f, the magenta correction key 6g, the cyan correction key 6h, the numerical value input key 6i, and the like of the keyboard 6 are operated to arbitrarily correct the color density of the scanned image (step 202), and then print processing is performed. (Step 203).
[0023]
Next, each worker confirms the quality of the finished print (step 204). If the quality standard is not cleared, the process returns to step 202, but if it is determined that the quality standard is cleared. The operator-specific color density correction data is registered in the correction data registration function 56 (step 205).
[0024]
Next, the case of performing a normal print processing operation in which an image on the film F is printed on the photographic paper P and developed by the above photographic processing apparatus will be described with reference to the flowchart shown in FIG.
[0025]
First, the reference data color density correction data is called from the correction data registration function 56 (step 301), and the color density correction data for each worker of the worker who performs the work is called (step 302). The correction value difference calculation function 57 of the control device 5 compares the color density correction data for each worker and the reference person color density correction data of the worker who performs the work, and calculates the difference between the correction values.
[0026]
Next, the image of the film F to be printed is scanned by the scanner 2 (step 303), and accordingly, the read image is first automatically corrected by the image automatic correction function 42. Thereafter, the images are sequentially displayed on the color monitor screen 30 of the display device 3, and the operator determines that further correction is necessary from among the images displayed on the color monitor screen 30 of the display device 3. Occasionally, by operating the keyboard 6, a yellow correction key 7f, a magenta correction key 7g, a cyan correction key 7h, a plurality of numerical value input keys 7i for increasing / decreasing a color tone or density correction value, etc. By performing an arbitrary operation, the color density of the image is corrected through the image manual correction function 53 (step 304).
[0027]
When the image color density correction is performed by the image manual correction function 53, the difference between the correction values calculated by the correction value calculation function 57 is added to the value of the color density correction of the image performed in step 304 (step 305). After that, the image is printed on photographic paper based on the added value (step 306).
[0028]
That is, for example, when the owner of the store serving as the reference person performs correction of +3 by the numerical value input key 6i or the like when correcting the color tone of yellow, for example, when creating the reference person color density correction data. When the operator creates the reference person color density correction data, for example, when correcting the yellow tone, when the +2 correction is performed by the numerical value input key 6i or the like, the operator performs the normal print processing. The yellow tone correction value +1, which is the difference between the yellow tone correction values calculated by the correction value calculation function 57, is automatically added to the correction value of the yellow tone correction, and the image is printed on the photographic paper P based on this addition value. The print process is performed.
[0029]
Thus, in the above photo processing apparatus, even if any worker corrects the color density of the image, the print can be finished with a color density that meets the quality standards recognized by the owner of the store as the reference person, The print quality can be kept constant regardless of individual differences among workers.
[0030]
In the above embodiment, the digital exposure apparatus 4a is used. However, the present invention is not limited to this. For example, so-called projection exposure in which a film image is directly transmitted through a photographic paper by a light source and exposed. You may use the thing of a system.
[0031]

Target As a result of the addition, even if the worker who performs the printing process changes, a stable quality print without individual differences, in other words, a print that clears the quality standard recognized by a reference person such as a store owner, for example, For example, store owners do not need to educate each worker about the quality standards of the store, and each worker makes his own judgment without being aware of the store's quality standards. Thus, color density correction can be performed.
