Title:
IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2013098873
Kind Code:
A
Abstract:

To reduce memory capacity of a memory used for loop filter processing.

A memory 261 stores image data in a region not included in a predetermined range used for filter operation in a case where filter operation of an image in a predetermined range from a right side block boundary is performed in a filter size whose tap number in a horizontal direction orthogonal to the right side block boundary is minimum, for example. When the filter size whose tap number in the horizontal direction is not minimum is selected, a filter control section 269 discriminates the tap located in the prescribed range and the tap whose image data is not stored in the memory on the basis of a position of a filter processing target pixel, and for the discriminated taps, copy of image data or change of a coefficient set used for filter operation is performed for performing filter operation without using image data not stored in the prescribed range or in the memory.
