An image processing apparatus inputs photographic image data containing dot-matrix pixels and converts the input pixels according to predetermined correspondence relationship information, so as to produce processed image data. A correspondence relationship holding unit of the apparatus holds correspondence relationship information, including a plurality of correspondence relationships, for the conversion, and applicable object information. The applicable object information includes, for each correspondence relationship, a respective condition. A correspondence relationship judging unit judges, for each of the input pixels, indicating whether a given pixel meets the condition of any of the correspondence relationships. An image data converting unit performs a conversion operation on the pixels of the input image data to produce processed image data. For each pixel, however, the conversion operation is performed using only the correspondence relationships indicated by the judgments of the correspondence relationship judging unit.

What is claimed is: 1. An image processing apparatus for inputting image data of a photographed image containing a plurality of pixels and for converting the image data of each of the pixels, the apparatus comprising: a first holding unit which holds a plurality of correspondence relationship information for a conversion of the image data; a second holding unit which holds color relationship information related to an applicable object color of an image processing, correlating the color relationship information to process content information representing details of the image processing; an applicable object judgment unit which judges, with reference to the color relationship information, whether a pixel corresponding to the input image data is the applicable object of the image processing; a correspondence relationship specification unit which, in a case where it is judged that the pixel is the applicable object of the image processing, with reference to the process content information correlated to the referenced color relationship information, specifies the correspondence relationship which actualizes the contents of the image processing from among the plurality of correspondence relationships; and an image data converting unit which, with reference to the specified correspondence relationship, converts the image data of the pixel for which the correspondence relationship is specified, wherein the first holding unit holds the correspondence relationship information in a form of a color conversion table which represents a correspondence relationship between pre-converted image data and post-converted image data. 2. An image processing apparatus as claimed in claim 1, wherein the second holding unit is a unit which holds a plurality of combinations of the color relationship information and the process content information, the applicable object judgment unit is a unit which carries out the judgment by with reference to the plurality of each color relationship information, and the correspondence relationship specification unit is a unit which, with reference to the process content information correlated to the referenced plurality of each color relationship information, specifies the correspondence relationship which actualizes each of the contents of a plurality of kinds of image processing. 3. An image processing apparatus as claimed in claim 1, wherein the first holding unit holds the correspondence relationship information in a tone curve form. 4. An image processing apparatus as claimed in claim 1, wherein the first holding unit holds the plurality of correspondence relationship information as another correspondence relationship generated by changing one correspondence relationship and its degree of correspondence relationship applicability. 5. An image processing apparatus as claimed in claim 1, wherein the second holding unit is a unit which holds the color relationship information, input by an operation of a user, and the process content information. 6. An image processing apparatus as claimed in claim 1, wherein the first holding unit holds, as the correspondence relationship, a relationship which changes a brightness based on the image data. 7. An image processing apparatus as claimed in claim 1, wherein the first holding unit holds, as a correspondence relationship, a relationship which changes a color vividness based on the image data. 8. The image processing apparatus as claimed in claim 1, wherein the color relationship information held by the second holding unit correlates the color of the pixel to the image processing suitable for the color of the pixel. 9. An image processing method for inputting image data of a photographed image containing a plurality of pixels and converting the image data of each of the pixels, the method comprising: as well as holding a plurality of correspondence relationship information for a conversion of the image data, holding color relationship information related to an applicable object color of an image processing, correlating it to process content information representing details of the image processing; judging, with reference to the color relationship information, whether a pixel corresponding to the input image data is the applicable object of the image processing; in a case where it is judged that the pixel is the applicable object of the image processing, with reference to the process content information correlated to the referenced color relationship information, specifying the correspondence relationship which actualizes the contents of the image processing from among the plurality of correspondence relationships; and with reference to the specified correspondence relationship, converting the image data of the pixel for which the correspondence relationship is specified, wherein the color relationship information is in a form of a color conversion table which represents a correspondence relationship between pre-converted image data and post-converted image data. 10. The image processing method as claimed in claim 9, wherein the held color relationship information correlates the color of the pixel to the image processing suitable for the color of the pixel. 11. A storage medium readable by a computer, which serves to store a program for converting image data of a photographed image containing a plurality of pixels, the program of instructions executable by the computer to perform functions for: judging, with reference to the color relationship information, whether a pixel corresponding to the input image data is the applicable object of the image processing; in a case where it is judged that the pixel is the applicable object of the image processing, with reference to the process content information correlated to the referenced color relationship information, specifying the correspondence relationship which actualizes the contents of the image processing from among the plurality of correspondence relationships; and with reference to the specified correspondence relationship, converting the image data of the pixel for which the correspondence relationship is specified, wherein the color relationship information is in a form of a color conversion table which represents a correspondence relationship between pre-converted image data and post-converted image data. 12. The storage medium readable by a computer as claimed in claim 11, wherein the color relationship information stored by the storage medium correlates the color of the pixel to the image processing suitable for the color of the pixel.
