Abstract

A digital teleconverter includes a component signal generation circuit, an encoder for obtaining a composite signal from the component signal, an image processing unit and a selector for selecting an image processing mode. The component signal generation circuit generates component signals comprising a luminance signal and color difference signals in response to an object image transmitted from an image pickup element. The encoder converts the component signals transmitted from the component signal generation circuit to a composite signal. The image processing unit performs a digital image processing on the basis of either the component signals or the composite signal. The selector selects either a video signal processed by and transmitted from the image processing unit or an original video signal of the object image.
