ABSTRACT:
An image to be printed in a CRT or video color printer is sensed to generate red, blue and green signals respectively representing a characteristic of the image in red, blue and green. The signals are processed in a matrix circuit to generate a luminance signal. The red and blue signals are subtracted from the luminance signal in operational amplifiers to obtain unadjusted difference signals. Each of the unadjusted difference signals is multiplied by an adjusting factor which is established using variable resistors and functions to provide level adjustment. The adjusted difference signals obtained in this manner are subtracted from the luminnce signal in respective operational amplifiers to yield modified red and blue signals. The modified red and blue signals are processed together with the luminanace signal in a second matrix circuit to generate a modified green signal. Control of color saturation may be achieved simply and inexpensively by adjusting the variable resistors and thereby changing the adjusting factor which determines color saturation.
