Abstract

PURPOSE:To compensate the outline to improve resolution, by taking out an outline compensation signal on a basis of a signal obtained by synthesizing only video signals, which are obtained from two image pickup elements shifted from each other by the 1/2 picture element pitch, in a proportion of 1:1. CONSTITUTION:Video signals G, R and B are subjected to gamma correction by process amplifiers 10-12 respectively and become video signals G', R' and B'. Only signals G' and R' are supplied to a mixing circuit 13 and are synthesized in a proportion of 1:1 to obtain a signal (0.5G'+0.5R'). An outline compensating circuit 14 outputs a signal (G'+R')' where an outline compensation signal is added to the signal (0.5G'+0.5R'). An adding circuit 19 supplies an outline-compensated lumi- nance signal Y' to an encoder 17. Signals R' and B' are supplied to low pass filters 20 and 21 also and become signals RL' and BL' of low-band components and are inputted to the encoder 17. As the output of the encoder 17, a color video signal with the resolution improved and the outline compensated is obtained.
