概述
描述
The JPEG Encode/Decode Software Library (referred to as JPEG Library) comprises the JPEG Decoder and the JPEG Encoder.
This software library is a FIT module based on the Renesas Firmware Integration Technology (FIT). You can easily embed specific software in user applications by combining the required FIT modules.
特性
- JPEG Decoder
- The JPEG Decoder is a JPEG image decoding library for Renesas MCUs, and includes the following two libraries.
- JPEG Decode Library: reverse DCT, reverse quantization, Huffman decoding
- Decode Library: decompresses a JPEG image in to a bitmap (16-bit color: RGB565 format) using the JPEG decode library
- JPEG Encoder
- The JPEG Encoder is a JPEG image encoding library for Renesas MCUs and includes the following two libraries.
- JPEG Encode Library: DCT, quantization, Huffman encoding
- Encode Library: compresses a bitmap (16-bit color: RGB565 format) into a JPEG image using the JPEG encode library
