Abstract
An image processor includes a hue region judging section judging which one of a plurality of hue regions corresponds to a hue and a converting section obtaining a correction value by using the hue to correct the hue based on the correction value. The converting section obtains a first difference value by using a difference between the hue and a first reference value, obtains a second difference value by using a difference between a second reference value and the first difference value, and obtains the correction value by using the second difference value. The hue is corrected based on the correction value.
Claims16
An image processor, comprising:
- a hue region judging section judging which one of a plurality of hue regions corresponds to a hue;
- and
- a converting section obtaining a first difference value by using a difference between the hue and a first reference value, obtaining a second difference value by using a difference between a second reference value and the first difference value, and obtaining a correction value by using the second difference value to correct the hue.
An image processor, comprising:
