13 Mpixel CMOS image sensor cuts power for 120 fps HD video

March 12, 2015 // By Graham Prophet
T4KB3 is a 13-megapixel backside illumination (BSI) CMOS image sensor with an optical format of 1/3.07 inch. Offering video capture at up to 120 fps with full 1080p HD, the image sensor is suited for use in high end smartphones and tablets.

With demand growing for small form factor chips, destined for ever slimmer mobile devices, the T4KB3 makes use of proprietary Toshiba design techniques to deliver a device claimed as the smallest 13 megapixel sensor. Low power circuitry has reduced power consumption, to 53% of that used by the preceding T4K82 image sensor, and the new chip achieves 200 mW, or less, at 30fps, with full 13 megapixel output.

Image brightness is boosted four fold by using Bright Mode technology and the T4KB3 offers full 1080p HD video capture at 120 fps. The sensor is fitted with 8 kbit of One Time Programmable (OTP) memory and lens shading correction data for two conditions can be stored. This permits different correction data for indoor or outdoor use. The T4KB3 measures 8.5 x 8.5 mm, with auto focus, and 6.7 x 6.7 mm with a static focus.
