The IP00C789 is an advanced warping and edge-blending chip that supports 120Hz input & output images up to 2K (2048×1200) pixels.

By using its dual-output capability, the IP00C789 can process 3D images for products such as head mount displays (HMD).

Thanks to its embedded warp table generator, the IP00C789 supports frame-by-frame pin-cushion correction as well as keystone correction.

The edge blending function has been greatly improved on this device by making use of a white-peaking algorithm for improved picture quality.

Using only 1 pc of DDR3 memory, the IP00C789 allows for a compact design without compromising on performance.

The IP00C789 is ideal for various kinds of 2K/WUXGA projectors from pico to high end models.

IP00C789 demo movie

The following demo movies are available.

If you would like to watch them, please contact info@i-chips.co.jp

IP00C788 RGB Color Independent Real-Time Warping Transition Demo Movie

This is a demo movie that switches color independent correction and warp table every frame.
IP00C788 now supports color independent warping, which was previously supported by the IP00C789.
By switching the warp table stored in the flash memory for each frame, the transformation transition is continuously displayed.
Note: The warp table is generated separately by software and stored in flash memory.
