Flex 4K

The Omnitek Flex 4K Soc is a silicon chip that offers advanced warping and edge blending of video images and allows rectilinear and arbitrary image warps to be applied to a video stream of 4K images (up to 4096 x 2400 at 60 frames per second). The Flex 4K device is ideal for projector image correction, camera lens correction and VR/AR applications.

The comprehensive specifications and functions of Flex allow it to be used in any application that requires image geometry correction such as projectors, video-walls, cameras and virtual reality headsets.

Flex 4K can be controlled via SPI and I2C ports to allow both low-level warp instructions (such as keystone correction, rotation, pin cushion and barrel correction) and high-level commands (such as forward and inverse grid transformations).

Omnitek’s SoCs reduce manufacturer development costs and time to market. The highly integrated devices delivering a very comprehensive set of functions reduce the bill of materials for consumer and Pro AV products and simplify PCB design.
