i-Chips IP00C790
4K Warping/Edge-blending LSI
The IP00C790 by i-Chips is an industry-leading LSI designed specifically for 4K warping and edge blending applications. With support for native 4K images up to 4096 x 2160 resolution and 60fps, this image chip sets new standards in image processing.
Featuring single-color processing capability for R, G, or B channels, the IP00C790 offers unparalleled flexibility. For full-color 4K implementation, multiple C790 chips can be utilized. However, the C790 chip simplifies the design process for 4K applications, thanks to its embedded frame memory and direct connection to the C734 front-end scaler via a proprietary interface.
The IP00C790 also includes advanced image quality control and correction features, such as per-pixel edge blending and uniformity correction, to deliver exceptional image quality.
This powerful image chip opens up exciting possibilities in various industries, including multimedia displays, projection systems, virtual reality, and more.
