PURPOSE:To obtain sharp picture with high resolution, by using a solidstate image sensor plate less in video element number comparatively, through the obtaining of luminance signal by synthesizing a sample hold output signal of each color. CONSTITUTION:The device is provided with a horizontal drive pulse generating circuit 4 generating a horizontal drive pulse to obtain repetitive color component signal of a given period with point sequential from a solidstate image sensing plate 8 locating color stripe filter in agreement with each video element, and a sample pulse generating circuit 23 to generate a plurality of sample pulses different from the phase through the use of the same or synchronized signal as the horizontal drive pulse. Further, the device is provided with a sample hold circuit 22 which separates each color signal from the said point sequential signal with the sample pulse of the circuit 23 and holds each color signal during consecutive readout period of three video elements, and an adder which synthesizes each color signal obtained from the circuit 22 and forms luminance signal component. |
