Toshiba Corporation (TOKYO:6502) announced the launch of “T4K82”, a 13-megapixel BSI1 CMOS image sensor that allows smartphones and tablets to record full HD video at 240 equivalent frames per second (fps), the industry’s highest2 frame rate. Sample shipments are scheduled to start in March.

High speed video recording requires a high frame rate with short exposure time, resulting in underexposed images. “T4K82” incorporates “Bright Mode” technology that 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% that of “T4K37”, a 13-megapixel sensor in mass production3.

About “Bright Mode”
“Bright Mode” technology secures double the exposure time by adopting interlaced4 video output, not the progressive5 output that standard CMOS sensors use. "Bright Mode" also employs charge binning6, 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.
