  • the color balance automatic adjustment execution flag Fwb is 1, automatic adjustment of image quality is executed for color balance.
  • An example of execution of automatic color balance adjustment is as follows. First, image data GD is analyzed, the distribution (histogram) of each component value of RGB (characteristics parameter values) is obtained, and the average value of the RGB component value is also obtained. Based on the obtained average value, the light source at the time of shooting (white point, white balance) is determined, and a reference value which is the optimal value as the average value for the determined light source is selected. The color skew of each component value of RGB in relation to the selected reference value is obtained, and the output level in relation to the input level or each component of RGB is adjusted using tone curve adjustment so that the color skew is eliminated.
  • FIG. 12 is a graph that conceptually shows the relationship between the input level and output level for the R component of the RGB components. For example, when the R component is larger than the average value of the RGB components, the output level is lowered according to the level of color skew at,the 3 ⁇ 4 point of the input level (OL 1 ). Meanwhile, when the R component is smaller than the average value of the RGB components, the output level is raised according to the level of color skew at the 3 ⁇ 4 point of the input level (OL 2 ). It is also possible to give an output value offset volume in relation to the input value according to the color skew (OL 3 ). The value that excludes the point that corresponds to the correction level is interpolated using a spline curve.
  • CPU 31 reflects the values of the characteristics parameters that were automatically adjusted in the image data, and returns the color balance automatic adjustment execution flag Fwb to 1 which is the default value (step S 360 ), and then returns to the image processing routine which is the main routine.
  • CPU 31 executes wRGB color conversion processing and half tone processing for printing (step S 250 ).
  • CPU 31 references the conversion lookup table (LUT) for converting to the CMYK color space that corresponds to the wRGB color space stored within ROM 31 , and changes the color space of the image data from the wRGB color space to the CMYK color space.
  • LUT conversion lookup table
  • it converts image data made from the gradation values of R, G, and B to, for example, data of the six color gradation values of C, M, Y, K, LC, and LM that are used with color printer 20 .
  • color printer 20 Before doing color conversion processing, when the resolution of the image data is lower than the printing resolution, linear interpolation is performed to generate new data between adjacent image data, and conversely when it is higher than the printing resolution, resolution conversion processing that converts the image data resolution to the printing resolution is executed by culling data at a fixed rate. Also, color printer 20 executes interlace processing that realigns the image data converted to a format that shows whether there is dot formation into the sequence in which it is to be transferred to color printer 20 .
  • color printer 20 of this embodiment when doing automatic adjustment of the image quality of the image data GD, when the light source, specifically the white balance, is specified, color balance is not automatically adjusted. Therefore, it is possible to obtain an output result that reflects the intention of the person shooting the image without losing the photographic effect brought by the light source (white balance) that was intentionally set by the person shooting the image.
  • the application is started by an operation by the user, the image file GF is read, the image output control information GI is analyzed, and conversion and adjustment of image GD is executed.
  • Another alternative would be that, by detecting insertion of the memory card MC, or by detecting insertion of a cable, the application starts automatically, image file GF is read, image output control information GI is analyzed, and conversion and adjustment of image data GD is executed automatically.
  • parameter selection buttons or photo mode parameter selection buttons that combine specific parameters according to the subject can be provided on the color printer 20 , and the parameters for executing automatic image quality adjustment can be selected using these selection buttons. Also, when automatic image quality adjustment is executed on a personal computer, the parameters for executing automatic image quality adjustment can be selected on the user interface of the printer driver or retouch application.
  • the image processing with color printer 20 can execute automatic image quality adjustment processing first and then execute color space conversion as shown in FIG. 13. It is also acceptable to process basic information.
  • color printer 20 is used as the output device, but it is also possible to use a display device such as a CRT, LCD, or projector as the output device.
  • a display device such as a CRT, LCD, or projector
  • an image processing program (display driver) that executes image processing as explained using FIGS. 10 and 11, for example, can be executed by the display device as an output device.
  • the image processing program is executed on the computer side.
  • the finally output image data has an RGB color space rather than the CMYK color space.
  • parameters including the light source, exposure correction volume, target color space, brightness, and sharpness as image output control information GI were used, but a user can decide freely what parameters to use as image output control information GI.
  • the values of each parameter shown as examples in the table of FIG. 8 are nothing more than examples, and the invention of this application is not limited by these values.
  • the values of matrix S, M, and N ⁇ 1 of the numerical formulas are also nothing more than examples, and it goes without saying that suitable changes can be made using something like a usable color space for color printer 20 .
  • an example of an Exif format file was used as the specific example of image file GF, but the format of the image file for the present invention is not limited to this.
  • the image file contains image data generated on the image data generating device and image output control information GI that describes the conditions (information) when the image data was generated.
  • image output control information GI that describes the conditions (information) when the image data was generated.
  • Digital still camera 12 and color printer 20 used in the embodiment noted above are nothing more than examples, and their structure does not limit the noted contents of each embodiment.
  • digital still camera 12 it is acceptable to at least provide the function of being able to generate image file GF of the embodiment noted above.
  • color printer 20 it is acceptable to at least analyze the image output control information GI of the image file GF of this embodiment, automatically adjust the image quality to reflect the intention of the user in relation to color balance in particular, and to output (print) the image.
  • image data GD and image output control information GI were contained in the same image file GF, but image data GD and image output control information GI do not necessarily have to be stored in the same file. In other words, it is acceptable if the image data GD and image output control information GI are correlated, and for example, association data that associates image data GD and image output control information GI can be generated, one or multiple image data and image output control information GI can each be independently stored in a file, and when image data GD is processed, its correlated image output control information GI can be referenced.
  • the image data and image output control information GI are stored in separate files, at the point of image processing that uses image output control information GI, the image data and image output control information GI are in a unified, inseparable relationship, because they have essentially the same function as when they are stored in the same file.
  • an embodiment for which image data and image output control information GI are used associated with each other is included in the image file GF of this embodiment.
  • animated image files stored on optical disk media such as CD-ROM, CD-R, DVD-ROM, and DVD-RAM are also included.
