Abstract
A camera module includes an image pickup portion, a motion detector, and a coordinate transformation processor. The motion detector detects a motion of the image pickup portion while an image of a subject is captured in the image pickup portion. The coordinate transformation processor executes coordinate transformation processing for collectively transforming coordinates of the image captured by the image pickup portion in such a way that effects on the image caused by camera shake of the image pickup portion, and by a distortion of an optical system used to obtain the image, are suppressed based on the motion of the image pickup portion detected by the motion detector, and based on a correction coefficient with which the distortion of the optical system is corrected. Technology used for the camera module may be applied to a CMOS image sensor.
