US 2006/0215756 A1 · Decoding circuit and decoding method

Abstract

A decoding circuit has first decoding section which receives first compressed image information, decodes the information, and outputs decoded image information, second decoding section which receives the first compressed image information or second compressed image information, decodes the information, and outputs decoded image information, buffer section which stores the decoded image information in storage region, and control section which responds to an instruction signal, if given, when the first decoding section is decoding the compressed image information by using storage region having first capacity of storage regions of the buffer section and outputting it to first output terminal, to thereby control the first and second decoding sections so that the second decoding section decodes and outputs the first or second compressed image information by using a storage region having second capacity smaller than the first capacity of the storage regions of the buffer section.

Dependent claims

A decoding circuit comprising:

a first decoding section which receive first compressed image information, decodes the information, and outputs decoded image information;
a second decoding section which receives the first compressed image information or second compressed image information, decodes the information, and outputs decoded image information;
a buffer section which stores the decoded image information in a storage region;
and
a control section which responds to an instruction signal, if given, when the first decoding section is decoding the first compressed image information by using a storage region having a first capacity of storage regions of the buffer section and outputs it to a first output terminal, to thereby control the first decoding section and the second decoding section so that the second decoding section decodes and outputs the first compressed image information or the second compressed image information by using a storage region having a second capacity smaller than the first capacity of the storage regions of the buffer section.

A decoding method for decoding compressed image information by using a storage region of a buffer section, the comprising:

decoding first compressed image information by using a storage region having a first capacity of storage regions of the buffer section and outputting it to a first output terminal;
and
responding to an instruction signal, if given, during the above step, to thereby decode and output the first compressed image information or second compressed image information by using a storage region having a second capacity smaller than the first capacity of the storage regions of the buffer section.
