Toshiba has developed a 2-megapixel BSI (backside illuminated) CMOS image sensor "CSA02M00PB" with LED flicker suppression for car-mounted cameras. Samples will be available starting from March 2016. The product is scheduled to be showcased at the 22nd ITS World Congress 2015 in Bordeaux, France, starting October 5, 2015.
By equipped with Toshiba's own LED flicker suppression circuit, successfully inhibited the flashing LED light source. The problem with the conventional on-board CMOS image sensor is that blinking images are output when the LED type signal and the logo are photographed, and can not be accurately identified. The new product to achieve a high-speed, accurate sensing. In the 2-megapixel image sensor, products with LED flicker suppression circuitry are the first in the industry.
The new product uses a new generation of self-developed by Toshiba HDR (High Dynamic Range) approach. This is a single-frame method, which reduces resolution degradation and provides a clear image without overexposure in environments with high contrast. In addition, the new product incorporates BSI for the first time in the company's automotive sensors, enabling bright images to be taken with high quality in darker environments than the original product.
In addition, the new product comes with features that support ASIL (Automotive Safety Integrity Level). But also meets the reliability standard "AEC-Q100 (Grade2)" for automotive integrated circuits. It is also suitable for front sensing cameras, electronic rear-view mirrors and CMS (camera monitoring system) for use in ADAS (Advanced Driver Assistance Systems) Use of the image displayed on the monitor.
The CSA02M00PB has an optical size of 1 / 2.7 inch. The pixel pitch is 3.0 μm. The output pixels are 1928 pixels (horizontal) × 1084 pixels (vertical). The output format is MIPI CSI-2 and Parallel. The maximum frame rate is 60 frames per second for double exposure and 45 frames per second for triple exposure. Dynamic range of 120dB (using HDR function). In terms of supply voltage, the analog part is 2.8V ± 0.2V, the digital part is 1.2V ± 0.1V, and the I / O part is 1.8V ± 0.1V. Package with 9mm × 9mm PBGA.
