Toshiba Launches 13 Megapixel CMOS Image Sensor

One of the world’s smallest chips, realizes low power consumption

TOKYO — (BUSINESS WIRE) — March 2, 2015Toshiba Corporation (TOKYO: 6502) today announced the launch of “T4KB3”, a 13 megapixel BSI[1] CMOS image sensor with the optical format of 1/3.07 inch for smartphones and tablets. Sample shipments start today.

In the market for mobile devices, a constant target for manufacturers is a small form factor; a final product that is thinner and lower in volume than products from other companies. Toshiba is meeting this need with a new design method that delivers smaller CMOS sensor chips.

The new design methodology helps to reduce the power consumption of the new 13 megapixel sensor to 53% of Toshiba’s sensor currently in mass production[2], to 200mW or less at 30fps. “T4KB3” is also world’s smallest class 13 megapixel sensor[3].

Short exposure time caused by high frame rate in high speed video recording usually produces underexposed images. “T4KB3”, however, uses “Bright Mode” technology to boost image brightness up to four times while realizing Full-HD video capture at 120fps equivalent.

The sensor incorporates 8Kbit of one-time-programmable (OTP) memory that can store lens shading correction data for two conditions; correction data for indoors and for outdoors, for example, which have different light profiles. These conditions can be separately applied to image correction, and users can switch from one to the other with a simple command for better image capture.

Integration of the sensor into smartphones and tablets will allow them to record high quality video at high speed, which extends imaging capabilities into such areas as slow motion replay. Reductions in module size and power consumption will contribute to smaller, thinner camera modules with a smaller form factor.
