Abstract:
An image processing apparatus comprising:a plurality of code-conversion devices for performing at least one of encoding and decoding by different codes, an internal memory being shared by said each code conversion device; anda control section for controlling an operation of said each code-conversion device;wherein said plurality of code-conversion devices, said internal memory and said control section are integrated in one chip, and coded data are converted to another coded data having a different form within the one chip, wherein said code-conversion devices comprise a first code-conversion device for performing encoding and decoding by MH code, MR code or MMR code and a second code-conversion device for performing encoding and decoding by QM code, and,in a code conversion process for converting the MH code, the MR code or the MMR code entered from the external bus to the QM code, said first code-conversion device and said second code-conversion device perform decoding processing of the MH code, the MR code or the MMR code and perform QM coding using a line memory secured in the internal memory, without outputting intermediate data to the exterior of the one chip.
