Picture signal processing circuit

Abstract

Abstract PURPOSE:To process a picture data of a multi-mode such as reduction and expansion of a piture,etc., by controlling the size of the picture reflected by selecting the combination of the first correlation operation and the second correlation operation. CONSTITUTION:As for an output 111 of an A/D converter 1000, the first correlation operation is executed by the first luminance signal operating circuit 1300, and its result is stored in a field memory 1400. As for a data of this memory 1400, the second correlation operation is executed in the output side, and its output is sent to an outputting circuit 3200 through a buffer memory 1600 and a luminance signal switching circuit 1900. On the other hand, the first correlation operation is executed by the first color signal operating circuit 2400, its output is stored in a field memory 2500, the second correlation operation is executed in its output side, and its result is supplied to the outputting circuit 3200 through a color signal switching circuit 2300.
