Toshiba Launches 13 Megapixel CMOS Image Sensor with High Speed Video Technology
Toshiba is launching the T4K82, a 13-megapixel BSI CMOS image sensor that allows smartphones and tablets to record full HD video at 240 equivalent frames per second (fps).
High speed video recording requires a high frame rate with short exposure time, resulting in underexposed images. The T4K82 incorporates the "Bright Mode" technology, which boosts imaged brightness up to four times, realizing full HD video capture at 240 fps equivalent. The new sensor allows smartphones and tablets to record high quality, high speed video, and to offer extended imaging functions including smooth slow motion playback and high speed continuous shooting.
The sensor also adopts a newly developed low power circuit design that reduces power consumption to 82% of Toshiba's that T4K37 CMOS, a 13-megapixel sensor currently in mass production.
"Bright Mode" technology secures double the exposure time by adopting interlaced video output, not the progressive output that standard CMOS sensors use. The technology also employs charge binning, which doubles the electrical charge of each pixel, resulting in an image four times brighter than that from a CMOS sensor without "Bright Mode". Toshiba will also provide an interlace-progressive conversion program that enables users to offer high quality progressive video with low image deterioration, without changing the frame rate.
Sample shipments of the new T4K82 are scheduled to start in March.
