Abstract
An image pickup apparatus comprises an image pickup section for converting an image of an object formed through a lens into an electric signal, a high frequency and low frequency separating circuit for separating the electric signal generated from the image pickup section into a high frequency component and a low frequency component, a gamma converting circuit for gamma correcting the electric signal of the low frequency component separated by the high frequency and low frequency separating circuit and a matrix circuit for adding the electric signal of the high frequency component separated by the low frequency and high frequency separating circuit and the electric signal of the low frequency component which was gamma corrected by the gamma converting circuit, thereby outputting a luminance signal and color difference signals.
