Nikkei technology online news, Toshiba camera for the development of the car with a LED flash suppression function 2 million pixel BSI (back illuminated) CMOS image sensor CSA02M00PB". Samples will be supplied from March 2016. Scheduled in October 5, 2015 in Bordeaux, France, held at the twenty-second ITS World Conference on the display of the product on the.

By means of the Toshiba LED suppression circuit, the flicker of LED light source is successfully suppressed. In the past, the problem of vehicle CMOS image sensor is that when the LED signal lamp is used and the logo is printed, the flickering image can be output and can not be accurately identified. The new products to achieve a high-speed, accurate sensing. In the 2 million pixel image sensor, equipped with LED flicker suppression circuit is still the industry's first product.

The new product uses Toshiba to develop a new generation of HDR (high dynamic range). This is a single frame mode, in the case of a large difference in light and shade can also reduce the degradation of resolution, the film will not be exposed to excessive exposure of the clear image. In addition, the new product in the company's vehicle sensors for the first time using the BSI method, compared with the original product, in a more dark environment can also be high quality shooting bright images.

In addition, the new product is equipped with a support ASIL (automotive safety integrity level) function. And in accordance with the "vehicle reliability standard integrated circuit AEC- Q100 (Grade2)", is also suitable for ADAS (Advanced Driver assistance system) with mirror and CMS camera, front sensor electronics (camera monitoring system) uses display image on the display in the car.

CSA02M00PB optical size is 1/2.7 inches. Pixel spacing of 3 m. The output pixel is 1928 pixels (horizontal) x 1084 pixels (vertical). The output format is MIPI CSI-2 and Parallel. The maximum frame rate is 60 frames per second, while the second exposure is 45 frames / sec at the time of the 3. Dynamic range of 120dB (using HDR function). Power supply voltage, the analog part is 2.8V + 0.2V, the digital part is 1.2V + 0.1V, I/O is 1.8V + 0.1V. Package using 9mm * 9mm PBGA.
