Patent ID: 8532199

Claim:
A moving image compression apparatus, comprising: an optical system; an imaging section configured to take a moving image of a shooting subject via the optical system and outputting moving image data; a camera control section configured to output a plurality of types of control information, the plurality of types including control information for controlling an operation of at least two of the optical system, shutter speed, digital zoom, and Automatic Gain Control; a moving image compression section configured to compress the moving image data using correlation between an image to be compressed and a reference image included in the moving image, the moving image compression section including a deblock filter configured to alleviate a block strain of the reference image in accordance with a set deblock filter strength condition; a deblock filter control section configured to set the deblock filter strength condition based on the control information, wherein setting the deblock filter strength condition based on the control information comprises finding for each of the plurality of types of control information a corresponding deblock filter strength condition, selecting from amongst the corresponding deblock filter strength conditions the corresponding deblock filter strength condition that provides a strongest deblock filter effect, and setting the selected corresponding deblock filter strength condition as the deblock filter strength condition; and a stream generation section configured to embed the set deblock filter strength condition in compressed output data.
