IMAGE PICKUP APPARATUS AND IMAGE PICKUP METHOD

摘要

An image of an object is focused on an image pickup element through a zoom lens and a diaphragm. The image focused on the pickup element is photoelectrically converted to an electric signal and supplied as an image signal to an amplifier circuit. In the amplifier circuit, the image signal supplied is amplified and digitized by an A/D converter. After this, the signal is supplied to a signal processing circuit. In the signal processing circuit, the image signal is subjected to clamp processing, color signal processing, luminance signal processing, contour correction, defect compensation, white balance correction, and the like. A camera CPU controls the zoom lens via a lens drive circuit, controls the pickup element via a timing generation circuit, and controls an auxiliary lighting block (7). Moreover, a signal from an operation block is supplied to the camera CPU.
