摘要：A plurality of divided exposure images (first to fourth images) are obtained bydividing a normal exposure time. By an image matching method, a motion detectioncircuit calculates a plurality of cumulative total correlation values between different
divided exposure images, and searches the plurality of cumulative total correlation valuesfor the smallest cumulative total correlation value, thereby calculating a motion vectorbetween the different divided exposure images. In addition, based on the level of thesmallest cumulative total correlation value, the level of reliability B[i] indicating theaccuracy of the motion vector is calculated. An image combining circuit uses the level ofreliability B[i] as a mixture proportion. The image combining circuit positions the dividedexposure images based on the motion vector, and combines the divided exposure imagestogether one on top of another in mixture proportions (B[i]), so as to form one stillimage that suffers less from camera shake.
