Abstract
PURPOSE: To enable to improve S/N together with the improvement of sensitivity to blue, by changing the constitution of combination of color stripe filters respectively provided with two pick up devices, in two plate type color pick up unit.
CONSTITUTION: The optical image of the objective 1 is branched into two at the half prism 3 through the pick up lens 2; one is formed at the photo sensitive section of luminance CCD 4, and another is to chroma CCD 3. Red and green signals R, G are picked up at the output terminals 19, 20 without any problem. As to blue signal B, since solidstate pick up device such as CCD has poor blue sensitivity generally and small output, the signal B picked up via the gate circuit 12 from CCD 4 is fed to the adder 22 through the LPF 12 having the band of fF/6 (fF is readout frequency for horizontal), it is added 22 with the output signal B of LPF 18 and picked up at the output terminal 23. Thus, since the signal B has corelativity between the outputs of each pick up device, the amount of signal is doubled than conventional systems.
