Document Type and Number:
Japanese Patent JP2810381
Kind Code:
B2
Abstract:
PURPOSE:To reduce the circuit scale by using a vertical low pass filter part for a luminance low pass filter and a color low pass filter in common. CONSTITUTION:A signal from a sensor 10 is subject to A/D conversion by an AD converter 11 and stored once in a memory 12. The data in the memory 12 is read sequentially at 1H (nearly 63mu sec) for each line in the noninterlace system and given to a zero inserting device 13. A 0 and a data in the output of the zero inserting device 13 are outputted alternately for each CLK1 and interpolated by 1280 sets per line. A vertical low pass filter 14 applies vertical low pass filtering in common to the brightness and color by the vertical low pass filter 14. Thus, the circuit scale is reduced.
