Abstract
An image processing apparatus includes a video decoder which subjects a stream signal to a decoding process based on an MPEG system, a de-blocking filter which subjects a decoded image signal decoded by the video decoder to a de-block filtering process, and a holding unit which previously holds a block boundary threshold value used as a condition for deciding whether the de-blocking filter performs a de-block filtering process.
Claims13
An image processing apparatus comprising:
- a video decoder subjecting an input stream signal decoding based on an MPEG system,
- a de-blocking filter de-block filtering a decoded image signal decoded by the video decoder, and
- a holding unit previously holding a block boundary threshold value used as a condition that the de-blocking filter performs a de-block filtering process as a representative value.
An image processing method comprising:
- subjecting an input stream signal to a decoding process based on an MPEG system by use of a video decoder,
- previously holding a threshold value in a holding unit, and
- using the threshold value as a condition for execution of a de-block filtering process when the decoded image signal is subjected to the de-block filtering process by use of a de-blocking filter.
