[0001]
BACKGROUND OF THE INVENTION
The present invention belongs to an image processing technique for processing image data obtained by capturing an image of a subject with an image sensor so as to realize an image expression intended by a photographer. More specifically, the image data is portable. The present invention relates to an image processing apparatus that processes when recording on a recording medium, an image processing apparatus that processes when printing image data read from a portable recording medium, and the like.
[0002]
[Prior art]
Many cameras, regardless of whether they are silver salt film cameras or digital cameras, can shoot by selecting a shooting mode suitable for the shooting situation from a plurality of shooting modes prepared in advance. For example, it is possible to easily perform shooting under optimum shooting conditions according to the situation, such as slow synchronization in the night shooting mode, high-speed shutter priority in the sport mode, and aperture opening in the portrait mode.
[0003]
These shooting modes are selected by the user operating the controls (mode selection buttons, dials, etc.) mounted on the camera. Therefore, the types of shooting modes that can be selected are the operations mounted on the camera. It is constrained by the number of children and their structure (number of dial steps, etc.). For this reason, with a conventional camera, only a limited number of shooting modes can be selected.
[0004]
In order to deal with this type of problem, in the field of silver film cameras, barcodes for selecting exposure control programs are printed on camera straps, film packages, etc., and the camera has a barcode reading function. In addition, a technique is known in which a camera can read a barcode of an exposure control program corresponding to a shooting situation so that shooting can be performed using an appropriate exposure control program. (See Patent Document 1)
[0005]
According to this prior art, by attaching a bar code for selecting an exposure control program to an object different from the camera, there is no restriction due to the number of controls mounted on the camera and its structure, The camera can have a variety of shooting modes.
In addition, by causing the camera to read the barcode attached to the film package, it is possible to fully exhibit the characteristics of each film by limiting the programs that can be selected depending on the type of film.

The communication unit 640 communicates with the printer 500. The image data and gamma correction parameter values received from the system control unit 620 are transmitted to the printer 500.
[0087]
The operation unit 650 is provided with an image selection button, a start button, and the like. The image selection button is an operator for designating a print processing target image from among images recorded on the portable recording medium 200. The start button is an operator for instructing the printer operation terminal 600 to start print processing. When the start button is pressed, the image data of the image to be processed and the parameter value for gamma correction are transmitted to the printer 500 together with the print request command.
[0088]
The display unit 660 includes a display device such as an LCD, and displays the status of the printer 500 and various messages.
[0089]
The tag reader unit 670 is configured in the same manner as in FIG.
[0090]
The system control unit 620 includes an EEPROM, a CPU, and the like (not shown), and the CPU executes various programs stored in the EEPROM to realize various functions of the printer operation terminal 600.
[0091]
Under the control of the system control unit 620, the tag reader unit 670 functions as a tag information reading unit that reads image processing parameter selection information from the wireless tag 310 attached to the portable recording medium 200. Further, the system control unit 620 itself functions as an image processing unit that adds a gamma correction parameter value corresponding to the image processing parameter selection information read by the tag reader unit 670 to the image data.
[0092]
Next, the operation of the printer operation terminal 600 configured as described above will be described with reference to the flowchart shown in FIG.
[0093]
When the print target image is selected by the operation unit 650 and the start button is pressed (Yes in S51), the printer operation terminal 600 reads the image data of the print target image from the portable recording medium 200 (S52). The data is expanded on the memory 630 (S53). Thereafter, it is confirmed whether or not the wireless tag 310 is attached to the portable recording medium 200 (S54).
[0094]
If the wireless tag 310 is not attached (No in S54), a default (default) gamma correction parameter value set in advance as a standard value is selected (S55).
[0095]
If the wireless tag 310 is attached (Yes in S54), image processing parameter selection information is read from the wireless tag 310 (S56). If the presence of the plurality of wireless tags 310 is confirmed (Yes in S57), the process proceeds to step S54.
[0096]
When there is only one wireless tag 310 (No in S57), it is confirmed whether the image processing parameter selection information read in Step S55 is information registered in the printer operation terminal 600 (S58). . As a result, if the information is not registered (No in S58), the process proceeds to step S55. If the information is registered (Yes in S58), the gamma corresponding to the image processing parameter selection information read in step S55. A correction parameter value is selected (S59).
[0097]
The parameter value for gamma correction selected as described above is added to the image data developed on the internal memory 430 (S60) and transmitted to the printer 500 together with the print request command (S61).
[0098]
As described above, when the printer operation terminal 600 according to this embodiment transmits (outputs) the image data read from the portable recording medium 200 to the printer 500, it is pasted on the portable recording medium 200. The image processing parameter selection information is read from the wireless tag 310 in the wireless tag seal 300. Then, a gamma correction parameter value corresponding to the read image processing parameter selection information is added to the image data.
[0099]
Therefore, according to the printer operation terminal 600, the wireless tag sticker 300 suitable for the purpose of photographing is pasted on the portable recording medium 200, thereby being added to the image data read from the portable recording medium 200. Selection of the parameter value for gamma correction can be performed while reflecting the intention of photographing.
[0100]
As a result, the printer 500 prints on the recording paper P an image whose color tone / gradation has been adjusted according to the purpose of shooting.
[0101]
In the above example, communication is used as a method of transferring image data and gamma correction parameter values from the printer operation terminal 600 to the printer 500. However, it may be transferred via the portable recording medium 200. .
[0102]
In the above example, the image data itself is not processed, but the image data to which the parameter value for gamma correction at the time of print processing is added is output to the printer 500, but the image processing parameter selection read from the wireless tag 310 is output. The image data may be processed according to the information and output to the printer 500.
[0103]
The target to which the RFID tag seal 300 is pasted is not limited to the portable recording medium 200, but may be a camera strap or a film package. The tag reader units 191, 470, and 670 may be configured so that the image processing parameter selection information can also be read from the wireless tag 310 of the wireless tag seal 300 attached to an object other than the portable recording medium 200. .
[0104]

[0105]
In addition, the image processing read out from the portable recording medium and the selection of data for gamma correction to be added to the image data when it is output to the printer are recorded on a wireless tag attached to the portable recording medium. This can be implemented while reflecting the intention of shooting based on the information.
[0106]
