Toshiba image sensor delivers in moonlight
Toshiba has an image sensor which can deliver a bright image even in moonlight.
Its TCM3211PB 1/4 inch VGA CMOS area image sensor is for security cameras, surveillance cameras and drive recorders.
The sensor adopts large 5.6 µm pixels, improving low light sensitivity. Even in moonlight, where lighting levels reach just 0.2 lux, bright images can be captured.
The sensor also incorporates a single frame HDR (High Dynamic Range) function that realises 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 coloration, where sensors produce colours not true to the imaged objects, is reduced and the sensor faithfully reproduces dark and bright areas in high contrast images.
The TCM3211PB’s frame rate is 60 fps at full resolution allowing the capture of video images in a 4:3 aspect ratio.
It comes in a PBGA.Tags: HDR, image sensor, security cameras, Toshiba image sensor
