Aptina Imaging, Micron's imaging division, has launched the MT9V126 CMOS sensor, a ¼-inch system-on-a-chip featuring VGA resolution and an NTSC/PAL output. The sensor has a high photosensitivity of <1lux and powerful integrated image processing capabilities.
The electronic image processing of this system-on-a-chip can correct distortions of up to 25 per cent, ideal for panorama lenses in automotive applications, for instance. Functionality for both perspective control and field of view selection and output is also directly integrated into the MT9V126.
A total power consumption of less than 300mW allows dynamic superimposing of texts and/or diagrams onto real time video images, supporting alpha channels (transparency) in the process and scaling the overlays according to a predefined distance. In this way, the MT9V126 can implement graphical driver support functionality in systems such as parking assistance, lane recognition or adaptive cruise control without additional image processing hardware.
