On Semiconductor has released a series of image co-processors for high dynamic range (HDR) 1080p automotive camera systems.
Designed to work in conjunction with the company’s high performance 2 megapixel and 1.2 megapixel image sensor devices, the new AP020x series of co-processors enable a full range of complete solutions for automotive rear view and surround view cameras. The new image co-processors all incorporate an advanced HDR colour pipeline with adaptive local tone mapping (ALTM). The AP0200, AP0201 and AP0202 support up to 2 megapixel 1080p image sensors, and the AP0102AT supports up to 1.2 megapixel 720p image sensors.
All of the co-processors offer support for functional safety features Automotive Safety Integrity Level (ASIL) levels A and B. In addition, they support 30fps operation at 1080p, 45fps at 960p and 60fps at 720p. Ethernet or parallel output interfaces are also supported, and I2C, SPI (Serial Peripheral Interface) and general purpose input/outputs (GPIOs) are incorporated. Each has an operating temperature range of -40°C to +105°C (ambient) and is fully AEC-Q100 qualified.
The AP0200AT is optimised 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 also has Ethernet output and is aimed at Ethernet-based surround view, while the AP0202AT is targeted at digital surround view and uses a 24-bit parallel output. Finally, the AP0102AT is targeted at 1 MP/720p rear view cams and includes the STE and overlay graphics engine.
The AP020x family will be offered as combined tuned solutions with existing image sensors such as the 1 megapixel AR0140AT, AR0132AT and AR0136AT, as well as the new AR0230AT 2 megapixel 1080p sensor.
The AP0200AT, AP0201AT, AP0202AT and AP0102AT are all offered in a VFBGA-100 package and are sampling now. The AR0230AT is available in an IBGA-80 and is also available for sampling. These parts will be available in mass production in 3Q 2015.
