摘要： 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.

摘要： There are provided a face image pickup device and a face image pickup method which can stably acquire a face image by appropriate illumination, and a program thereof. The face image pickup device comprises a camera which picks up an image of a face of a target person, an illumination light source which illuminates the face of the target person with near-infrared light having an arbitrary light amount, and a computer. The computer detects an area including an eye from the face image of the target person picked up by the camera. The computer measures a brightness distribution in the detected area. Thereafter, the computer controls the illumination light source so as to change the amount of near-infrared light based on the measured brightness distribution.
