Shaking detection device, shaking correction device, imaging device, and shaking detection method
Abstract:
A data thinning unit prepares thinned images by extracting only one component in raw data of each of a standard image and reference image, a block extracting unit extracts a search block and a template block for finding residual differences, a luminance difference comparing unit obtains a difference between the maximum value and the minimum value of luminance values of each block, and, when smaller than a threshold value, excludes this from a scope of acquisition of residual differences. The residual difference acquiring unit acquires residual differences from blocks which were not excluded, a block selecting unit selects a predetermined number of blocks having small residual differences, and a hand shake (blur or unintentional movement) acquiring unit finds a position of the template block at which the residual difference becomes the minimum, calculates a center value of all positions, and defines the same as the amount of hand shake.
