Abstract
The image processing system includes: an image pickup apparatus (10) including image pickup elements of a color difference line sequential system that outputs, as video signals, a luminance signal (Y) and a line sequential, color difference signal (U/V); and an image processing apparatus (20) which includes a signal interpolator (21) for interpolating the line sequential color difference signal (U/V) to separate the line sequential color difference signal (U/V) into two color difference signals (V) and (U). With this configuration, only two video signal lines are required to connect the image pickup apparatus (10) and the image processing apparatus (20), and even though the number of signal lines is reduced, image quality deterioration is suppressed.
