Product Brief
Highlights
• Major worldwide
producer of image
sensor technology with
more than 25 years of
experience.
• Many of the Toshiba
image sensors utilize
advanced technologies
such as Backside
Illumination (BSI), High
Dynamic Range (HDR)
and Color Noise
Reduction (CNR) for
better image quality and
truer colors.
• Utilizes a proprietary
square-pixel design that
enables exceptionally
high-quality images with
low-power consumption.
• Offers a wide range of
sensors from VGA to
20-megapixels (MP).
• Makes ongoing
investments in capacity
and its robust supply
chain is a result of tight
procurement
relationships and
experience in designing,
developing and
manufacturing image
sensors.
T4KA7 20-Megapixel CMOS Image Sensor
Description
The Toshiba T4KA7 is a 20-megapixel (MP)
1.12-micron BSI pixel CMOS image sensor
for high-end mobile handsets and
smartphones. With an optical format of 1/2.4
inch, the T4KA7 sensor enables
development of camera modules with a zheight of 6 mm or less to meet consumer
demand for thinner and lighter mobile
devices. The T4KA7 uses high-speed
circuitry to deliver frame rates of 22 fps at
full-resolution capture. The sensor features
BSI and advanced digital zoom capability
that removes discernable image
deterioration even when zooming in very
close on a subject. This sensor expands the
Toshiba 1.12-micron family of 8 MP and
13 MP sensors, which enable low-power,
high-performance image capture and video
recording.
