Title: Apparatus and method for processing image
Inventor: TOYODA YASUTAKA
IPC: H04N1/405
Filed: 2001-10-05
Abstract: PROBLEM TO BE SOLVED: To obtain a color correction adapted to a gradation reproducing capability of a device without performing a complicated calculation by using a color correction table having a small memory capacity. SOLUTION: The method for processing an image uses the color correction table obtained by forming the table of the relationship between a discrete input color signal and an output color signal corresponding to the input signal. The method comprises steps of correcting the input color signal by a signal correcting unit 12, and obtaining the discrete input color signal similar to the corrected input color signal by an approximating unit 13. A table referring unit 14 refers to the color correction table, and outputs an output signal (gradation data and switching data) corresponding to the input color signal approximated by the approximating unit. An approximating error generating unit 17 calculates the approximating error from the difference between the input and the output to the approximating unit, and stores the error in a data storage unit 15.  The stored approximating error is supplied to the correcting unit 12, and used for correcting the input signal. The switching data is used for a dither process, and a dither result is added to the gradation data, thereby napidly outputting the color correction result adapted to the gradation reproducing capability of the device.

Filed: 2001-10-12
Abstract: PROBLEM TO BE SOLVED: To rapidly perform a color matching operation along with color matching before initiating a regular printing and during the regular printing. SOLUTION: The content of memory for storing a printing state is set as '0'. When a printing state switch is set in the '0' position, the memory for storing a printing state is set as '1'.

Further, the adjustment value of an aperture level of an ink key is multiplied by α1 and a correction value of the aperture level of each ink key is sought (step 133).  When the memory for storing a printing state is set in the '1' position (YES of step 130), a second factor α2 (α1>α2) is read, assuming that '1' means the color matching during the regular printing (step 132) and the adjustment value of the aperture level of each ink key is multiplied by α2 to seek the correction value of the aperture level of each ink key (step 134).
