Silicon IP Cores
Camera Front-End and WDR/HDR Image processors
Interface your image sensors, perform image processing functions, and provide your application with great-quality video using a basic ISP or an advanced WDR/HDR core from CAST.
The CAMFE Camera Front-End Processor Core accepts the raw pixel output from an image sensor and produces standard RGB video ready for compression or other uses. The processor converts the Bayer pattern sensor output—via de-mosaicing interpolation and white balancing—and optionally optimizes the video with Contrast Stretching (Normalization), Gamma Correction, and Sharpening.
These photos depict the results from the series of image optimzation steps the Camera Front-End Processor Core can execute.
One of the many new challenges facing automotive designers is incorporating live video imaging. The Low-Power, Low-Latency HDR/WDR Image Processor is especially good for improving video quality for the challenging real-world scenes typical to the automobile environment.
It uses a wide dynamic imaging technique to dramatically improve high-contrast scenes that have a mix of well-lit and very dark areas. This technique combines up to four narrow range exposures to produce a wide dynamic range image with great clarity throughout the dark and bright portions of the scene.
Supporting Full HD video at 120 frames per second even in FPGA devices, the WDR processor is suitable for automotive cameras and many other applications, including surveillance, industrial machine vision, and video analytics.
