GL3004
Overview

Genesys Logic GL3004 is a high performance and feature-rich fisheye image processor optimized for a wide range of image sensors and fisheye lenses, supporting powerful fisheye correction methods including customized fisheye correction, spherical panorama dewarping, perspective projection dewarping, and achieve nine dewarping modes to enhance the wide-angle visual perception. In addition, the GL3004 embeds hardware image signal processor (ISP), wide dynamic range (WDR), OSD function and support input resolution up to 3 megapixels, providing real-time and superior visibility technology for wide-angle camera applications.


The GL3004 integrates fisheye correction engine, image processor, display engine, MCU 8051, memory controller and common interface, including 2-lane MIPI (TX/RX), DVP (in/out) and BT601/656/1120 output interfaces. The SPI flash and DDR2 memory are also embedded in the GL3004 MCP package in order to reduce product PCBA area.   

GL3004 is a dedicated fisheye image processor for wide-angle application. The proprietary dewarping engine provides various mathods of fisheye correction. The complete image signal processing (ISP) offers true color processing capabilities.The display engine accomplishs a rich dewarping effect that satisfies the diversity of wide-angle scenes and enhances human visual experience.
