画揺れ補正装置

Image shake correcting device

Abstract

PURPOSE: To prevent the lowering of image quality corresponding to correction by specifying a common area from first and second memories in the case of detecting a shaking and rewriting second memory image information to first memory image information. CONSTITUTION: A shaking detection part generates the information showing shaking amount and the shaking direction based on a motion signal Ss and notifies the information to a memory control part 7. The control part 17 recognizing this notification starts a rewriting control means 18 and the means 18 specifies the area which is common to images Fold and Fnew or a common area. When the common area is specified, the means 18 reads the image information D1 constructing the common area from a first field memory 13 and writes the image information constructing the common area on a second field memory 14 in a stored area. Namely, only the image information constructing the common area on the memory 14 is rewritten. As a result, since the same information capacity as that of images Fold and Fnew is constructed in an image Fout, image information is reduced and the lowering of image quality can be prevented.
