ABSTRACT:
A screen correction method and image pick-up device suitable for use in, for example, digital cameras. Horizontal and vertical signals from a signal generator (SG) are supplied to a semiconductor image pick-up device (CCD) via a timing generator (TG). Horizontal and vertical counter values from the signal generator are supplied to a distance calculation block, and the distance from optical axis center position information, provided from terminals5X,5Y, is calculated. This calculated distance value d is supplied to a converter (conv), and a distance value, converted according to information from the terminal on the number of pixels of the semiconductor image pick-up device, is supplied to a lookup table (LUT), to output the correction coefficients according to the distance from, for example, the optical axis center position.
