Abstract
A color image processing apparatus which performs different color processes for different areas of an input image. The color image processing apparatus stores a plurality of conversion tables used to output color processed data, inputs a command from an external apparatus, and analyzes the input command. The color image processing apparatus also selects a conversion table from among the plurality of conversion tables on the basis of a result analyzed by the analyzing means, and generates the color processed data by performing a color process for each of the different areas of the input image using the selected conversion table.
Claims19
A color image processing apparatus which performs different color processes for different areas of an input image, comprising:
- storing means for storing a plurality of conversion tables used to output color processed data;
- input means for inputting a command from an external apparatus;
- analyzing means for analyzing the command input by said input means;
- selecting means for selecting, for each of the areas, a conversion table from among the plurality of conversion tables on the basis of a result provided by said analyzing means;
- and
- color process means for generating the color processed data for each area of the input image, by performing a color process for that area of the input image using a conversion table selected by said selecting means.
A color image processing apparatus which performs different processes for different areas of an input image, comprising:
- input means for inputting a command from an external apparatus;
- analyzing means for analyzing the command input by said input means;
- selecting means for selecting, for each area, a process from among a plurality of processes which have different conversion characteristics on the basis of a result provided by said analyzing means;
- and
- process means for converting multi-value image data to multi-value processed image data for each area by performing a process which corresponds to that area of the input image using a conversion table which corresponds to a process selected for that area.
A color image processing method which performs different processes for different areas of an input image, comprising the steps of:
- inputting a command from an external apparatus;
- analyzing a type of command input in said inputting step and extracting information related to a process;
- selecting, for each area, a process from among a plurality of processes which have different conversion characteristics on the basis of a result obtained in said analyzing step;
- and
- converting multi-value image data to multi-value processed image data by performing a selected process for each area of the input image.
