Title:
SIGNAL-PROCESSING UNIT AND IMAGE-PICKUP DEVICE
Document Type and Number:
Japanese Patent JP3943655
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reproduce an image up to a high-frequency component, in comparison with a single sampling and to realize reproduction of an image of a signal without loopback noise, even from a single image.
SOLUTION: For relating to this device, an object image received optically by a lens 101 is given to a low-pass filter 129, from which different high-frequency components or higher are passed reduced, an object image passed through the low-pass filter 129 is sampled by a light-receiving element pitch in a CCD 103A, to obtain image information. In this case, high-frequency components or higher are passed through the low-pass filter 129 reduced and plural image information sets are received from the CCD 103A and plural image information sets are composited.
