Toshiba today announced the launch of “T4KA3”, an 8-megapixel BSI CMOS image sensor that allows smartphones and tablets to record HD video at 240 equivalent frames per second (fps), the industry’s highest frame rate. High speed video recording requires a high frame rate with short exposure time, resulting in underexposed images. Toshiba T4KA3 incorporates Bright Mode technology that boosts image brightness up to four times, realizing HD video capture at 240 fps equivalent. Toshiba T4KA3 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 incorporates 8Kbit OTP that can store two conditions of lens shading correction data. It can recognize light conditions and change the correction data by one command of I2C. The T4KA3’s is also in the smallest class for 8M sensors supporting HDR. The sensor adopts a newly developed low power circuit design that reduces power consumption to 85% that of Toshiba T4K35, an 8-megapixel sensor in mass production. Sample shipments of Toshiba 8-megapixel BSI CMOS image sensor T4KA3 start today.
