Image sensor addresses specific demand of automotive cameras

December 05, 2012 // By Christoph Hammerschmidt
For the specific demands of automotive applications such as high dynamic range and durability, Toshiba Electronics Europe (TEE) has developed the TCM5114PL CMOS image sensor. The device could also suit applications in surveillance cameras.

Unlike their counterparts in mobile phones, image sensors in automotive and surveillance applications must be able to capture images in low light conditions (e.g. in moonlight) and high contrast 'light-to-dark' and ‘dark-to-light’ situations.

The TCM5114PL employs a large, 5.6µm x 5.6µm pixel pitch that allows it to capture images in low light, which is difficult to achieve with conventional sensors. In addition, the device features an embedded High Dynamic Range1 (HDR) algorithm that enables the capturing of high quality, natural looking images when moving from light to dark and vice versa (e.g when reversing into a dark garage from bright daylight).

Furthermore, the TCM5114PL features relevant functions such as Auto Luminance Control (ALC), Auto Exposure (AE), Auto White Balance (AWB), Lens Shading correction (LSC), Auto Flicker Detection and Correction (AFD) and Bad Pixel Correction (BPC).

The sensor is supplied in a ¼-inch optical format and has a package size of 10.5mm x 10.0mm. Both digital and NTSC/PAL format analogue outputs are available, supporting connectivity with a wide variety of display panels.

The TCM5114PL is based on a process that supports the long-term, reliable operation demands of automotive and surveillance applications. A single 3.3V power supply minimizes the need for additional regulators, reducing component count and board space and further enhancing system reliability.
