IMAGE SIGNAL PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2000/049595
Kind Code:
A1
Abstract:
An image signal processing device capable of displaying all image signals, using a simple circuit configuration, on a display having fixed display pixels without missing them, wherein a one clock delay circuit (1) outputs reference signals (9) with one clock delay, a multiplexer (2) alternately outputs the one clock-delayed signals and reference signals (9), an A/D converter (3) performs the two-phase processing on the image signals (24) based on the output signals from the multiplexer (2), a comparator (8) outputs control signals (12) to the multiplexer (2) so that it can select one clock-phase shifted signals when it judges, based on the detected results obtained from the first and second back porch detection circuits (6) and (7), that the head of the image data is not present in the first phase output data.
