ROHM introduces built-in fog image correction features video encoder IC

Semiconductor manufacturer ROHM co., Ltd., recently, for surveillance cameras and home safety equipment, vehicle travelling data recorder, etc installed camera module device, developed industry's first built-in fog image processing features video encoder IC 「introduction BU6521KV 」.

This new product, from September 2009 start supply samples (sample price 1,200 Yen/unit), will begin December 2009 to produce 10 000 scale mass production. Production process of the preliminary procedure at ROHM co., Ltd. Headquarters (Kyoto City), late-stage process at ROHM ELECTRONICS PHILIPPINES INC. (Philippines).

Epilogue in safety, for monitoring camera and on-board camera and other areas, especially outdoor high recognition of requirements, in bad weather conditions can ensure the visibility of the image correction technologies growing demand.

ROHM, please prepare the corresponding to various image formats of image processor and TV Encoder, broad product portfolio, especially the built-in AIE (Adaptive Image Enhancer is a unique hardware ROHM image correction technologies) video encoder IC 「introduction BU6520KV 」, backlight and night dark environment and enhancing the camera's image identification, surveillance cameras, video cameras and other equipment in the vehicle were highly evaluated. This, on the basis of 「introduction BU6520KV 」 equipped on fog or mist, fuzzy not sharp images in real time correction feature, developed industry-first fog image correction features video encoder IC 「introduction BU6521KV 」. ROHM original fog image correction technology, is the establishment of the photographic input image brightness histogram distribution, make this information as a basis for comparison correction, color correction and output. Due to this technology, so that a white mist with image contrast significantly improved, but also the color of the display disappears, greatly improving the recognition. In addition, because of the need to determine is the fog and mist of 「introduction belt white 」, installed can automatically make the appropriate correction feature, no need for external devices such as a CPU can change on the natural environment. Use this function, even when environmental changes caused by changes in the concentration of the mist, or you can put the image into continuous correction has no effect when the fog. In addition, monitoring camera, in-car cameras, and other areas, in addition to the required image identification also require real-time processing of image correction. If the software is in fog image correction process, due to the fog image correction of volume calculation, only the number of measurement frequency: fps (frame per second fps. Every 1 second can process images in total) to make the correction. But 「introduction BU6521KV 」, in order to achieve high-speed processing using the most appropriate calculation algorithm of hardware, frame rate up to 30fps. ROHM, play high image processing technology will continue to develop in line with customer requirements, products will be further efforts to expand the full product line.
