The RB5C634A is a one-chip coder equipped with image compression function of generating JPEG2000-compliant codes and decompression function of decoding images from the JPEG2000-compliant codes. It provides powerful encoding and decoding functionality by simply setting up parameters in the internal registers. This coder can process an image of up to 1024 x 1024 pixels within one tile, which presents the ideal solution for reducing the degradation in image quality to a large extent.
The Ricoh RB5C634A is a one-chip coder equipped with image compression functionality for generating JPEG2000-compliant codes and a decompression function for decoding images from these codes. It supports processing images up to 1024 x 1024 pixels within one tile and includes rate control to manage compressed code size. The device features selectable wavelet filters (R5-3 or IRQ-7) and automatically generates necessary headers during compression and interprets them during decompression.
