CMOS image sensor targets security applications

The sensor adopts large 5.6µm pixels, improving low light sensitivity. Toshiba claims bright images can be captured even when lighting levels reach just 0.2lux. The sensor also incorporates a single frame HDR function that realises a high dynamic range of 108dB. The HDR function is based on an algorithm developed by Toshiba that simultaneously applies different exposure times to each line of an image and incorporates them into a single image. False colouration, where sensors produce colours not true to the imaged objects, is reduced and the sensor reproduces dark and bright areas in high contrast images. Available in a PBGA package, the TCM3211PB offers a high frame rate of 60fps at full resolution and enables video capture in a 4:3 aspect ratio.
