<p>A color signal adjustment circuit used in, for example, a camera device, in which specified color signals can be adjusted and, in addition, color signals can be adjusted with a smaller information volume. A chroma serial I/O interface SIO (41) generates a pre-set control signal, under the control of a micro-computer (50) subject to a setting operation on an operating unit, and judges, at the time of conversion of the color difference signal in a phase/gain control circuit (36), if phase processing or gain processing is carried out, which of the ÄR-YÜ signal and the ÄB-YÜ signal is controlled and in which quadrant the color adjustment is made, in order to send X and Z signals meeting with these judgment conditions to a phase/gain adjustment circuit (36B) pixel-by-pixel. The phase/gain adjustment circuit (36B) generates ÄR-YÜ and ÄB-YÜ signals from ÄR-GÜ and ÄB-GÜ signals based on the X and Z signals. <IMAGE></p> |
