ON Semiconductor has enabled high dynamic range (HDR) 1080p automotive camera systems with the introduction of their new series of image co-processors. Designed to work in conjunction with the company’s high performance 2 megapixel (MP) and 1.2 MP image sensor devices, the AP020x series of co-processors enable a range of solutions for automotive rear view and surround view cameras.https://cdn.specpick.com/images/photonics/unknown_300.jpg712370
According to Sandor Barna, Vice President of Automotive Imaging and Scanning Division at ON Semiconductor the automotive co-processors supply automotive customers with a wider range of camera solutions for both high performance 1080p and 720p video. In order to specifically address customer requirements, they have added higher resolution, multiple interfaces and new automotive-targeted features such as ASIL support.
The image co-processors incorporate an advanced HDR color pipeline with adaptive local tone mapping (ALTM). The AP0200, AP0201 and AP0202 support up to 2 MP 1080p image sensors, and the AP0102AT supports up to 1.2 MP 720p image sensors. All of the co-processors offer support for functional safety features Automotive Safety Integrity Level (ASIL) levels A and B. They support 30 frames/second (fps) operation at 1080p, 45 fps at 960p and 60 fps at 720p. They also support Ethernet or parallel output interfaces, and incorporate I2C, SPI (Serial Peripheral Interface) and general purpose input/outputs (GPIOs). Each has an operating temperature range of -40 °C to +105 °C (ambient) and is fully AEC-Q100 qualified.
- The AP0200AT image co-processor is optimized for rear view cameras and offers Ethernet output. It also includes a spatial transform engine (STE) which enables lens distortion correction and de-warping, as well as a sophisticated overlay graphics engine.
- The AP0201AT image co-processor also has Ethernet output and is aimed at Ethernet-based surround view.
- The AP0202AT image co-processor is targeted at digital surround view and utilizes a 24-bit parallel output.
- The AP0102AT image co-processor is targeted at 1 MP/720p rear view cams and includes the STE and overlay graphics engine.
The AP020x family is being offered as combined tuned solutions along with the existing image sensors such as the 1 MP AR0140AT, AR0132AT and AR0136AT, as well as the new AR0230AT 2 MP 1080p sensor. The combination solutions of sensor and co-processor provide automotive Tier 1s with a wide range of options for multiple market segments, while speeding time to market.
