Clairvu™

Full HD, 4K Image Signal Processing Engine

CIS own designed, algorithm engine for Full HD and 4K 240p (8K 60p) camera signal processing.
High Resolution, low pseudo‐color and low artifact CI (Color Interpolation) process produces video image quality equivalent to that of digital single-lens reflex camera.
We offer hardware IP licenses such as HDR, 3DNR, DRE, and Dehaze processes which are modular in design and fully optimized for implementation on off-the-shelf FPGAs.
You can choose any combination of IPs to achieve exceptional image quality.

Feature

High Quality Image

High resolution, low pseudo‐color, and low noise color interpolation process produces high quality images equivalent to that of non‐real time PC‐based DPE application software.

Precision Color Reproduction

Enables precise color reproduction by way of sophisticated color compensation technology (multiple‐axis division of the color plain).

High Speed yet Cost Effective

Algorithm engine that processes up to 8K image signals can be implemented into a relatively small, a medium sized FPGA. It processes 4K image signals at 240fps and 8K image signals at 60fps.

Baseline Modules

Noise Reduction (2DNR)

Noise reduction by spatial filter.

Color Interpolation (CI)

Color interpolation process produces color images out of signal output from Bayer array color sensor, and significantly affects its image quality. “Clairvu™” enables high resolution, low pseudo-color, and low noise at the same time.

Color Correction (CC)

Enables finely-tuned color adjustment by applying different correction factor to the region color-by-color.

Edge Enhancement (YEE)

Sharpens the edge of images.

Optional Modules

Noise Reduction (3DNR)

Along with NR by spatial filter, CIS developed 3DNR to calculate the data among frames. 3DNR process reduces temporal noises without losing sharpness/acutance of the images.

Wide Dynamic Range (ＷDR)

Synthesizes two images with different exposure, and produces composite image with wide dynamic range. Proper contrast and adequate color tone are kept.

Dehaze

Removes the haze from image by way of enhancing contrast locally.
