Abstract
An imaging sensor unit captures a subject through an optical system. A compression unit compresses image data continuously acquired from the image sensor unit to output to a recording unit. A feature amount extraction unit extracts a feature amount for each pixel of the image data and a coordinate selection unit selects a plurality of coordinates having a relatively high feature amount. A movement detection unit detects a movement vector of coordinate points according to the plurality of coordinates selected by the coordinate selection unit. A geometric deformation parameter generation unit generates a geometric deformation parameter based on the movement vector and lens information for the optical system. The recording unit records the geometric deformation parameter in association with the image data compressed by the compression unit (each frame of the image data).
