摘要： An image processor detects an on-screen motion of a photographic subject in video image data generated by an image sensor provided in a camera body and outputs a photographic subject motion information. A sensor detects a motion of the camera body and outputs the detected motion as a camera body motion information. A scene decision encoding controller decides an image pickup condition of the video image data based on the photographic subject motion information and the camera body motion information, and performs an encoding amount regulation control suitable for the decided image pickup condition to an image compression processor.

摘要： A frame skipping process suited to a scene is achieved by providing an encoder which encodes input image data, an encoding determination unit which compares image movement information with a threshold to determine whether or not encoding is to be performed, a frame skipping controller which performs a frame skipping control if encoding is not to be performed, and a threshold correction unit which corrects the encoding determination threshold based on the result of the encoding process. The image movement information used in the encoding determination unit is any one or a combination of pixel movement information obtained by a representative point matching scheme performed by a pixel movement calculation unit, angular velocity sensor information obtained from a lens controller, and frequency information obtained from an image processor.
