San Jose, Calif. - Toshiba America Electronic Components, Inc. (TAEC) unveils the CSA02M00PB CMOS image sensor for automotive cameras. Toshiba claims the 2-megapixel (MP) CMOS image sensor as the industry's first to be equipped with a LED flicker (pulsed LED) mitigation circuit to minimize image flicker caused by LED light sources.
“When recording LED traffic lights and signs with conventional CMOS image sensors, the output image often flickers, hindering sensing accuracy. Toshiba designed the CSA02M00PB to curtail this flickering and deliver clearer images for faster, more accurate image sensing,” the company said.
The new sensor integrates Toshiba's next-generation High Dynamic Range (HDR) system and backside illumination (BSI) process, which together enable recording of high-precision images. The HDR system uses Toshiba's single-frame method to achieve clear images free of the degraded resolution and blown-out highlights typical of high contrast-light conditions, while the BSI process makes it possible to shoot brighter pictures with higher image quality in low light conditions, said Toshiba.
The sensor meets the requirements of Automotive Safety Integrity Level (ASIL), a risk classification scheme defined by ISO 26262 (the Functional Safety for Road Vehicles standard intended to protect life), and supports failure detection, report flagging and control of vehicles. It is compliant with AEC-Q1004 (Grade 2) and can be used in ADAS front-end sensing cameras and the latest viewing applications, such as e-Mirror5 applications and camera monitor systems.
The CSA02M00PB features 3-micrometer BSI pixel size and an optical size of 1/2.7 inch. Image output ranges from 45 to 60 frames per second (fps), depending on the HDR exposure condition. Housed in 9x9 mm PBGA package, the sensor features full-HD output resolution of 1928(H) x 1084(V) and dynamic range of 120dB (by Toshiba calculation) with HDR. The MIPI CSI-2 serial interface facilitates the sensor's integration into end products, said Toshiba
Availability: Samples will begin shipping in March 2016.
