Mobile device manufacturers are constantly striving to design and build the most powerful and efficient devices with the smallest possible form factors. To support this need for smaller components, Toshiba has developed a design method that enables smaller CMOS sensor chips and low-power circuitry. Examples of this method include the recently released T4KA3, the T4KB3, and now the T4KC3.
The new sensor's functional range supports the capture of beautiful images and videos. Phase-Detection Autofocus (PDAF), recently incorporated into SLR cameras, achieves fast focusing that surpasses conventional object autofocus, making it easier for mobile devices to capture not only static objects but also fast-moving ones.
Image brightness is increased up to four times with Toshiba's Bright Mode technology, which enables the capture of HD video at the equivalent of 240fps. It also supports high dynamic range (HDR) for capturing natural images of scenes with high contrast ratios, eliminating the problem of overexposed and underexposed images.
The T4KC3 achieves output speeds of up to 30 fps at full 16MP resolution (4624 x 3472 pixels) with power consumption figures of just 240 mW or less. Full HD outputs of 1920 x 1080 pixels are supported at frame rates of up to 60 fps, and HD outputs (1280 x 720 pixels) support 120 fps in normal mode and 240 fps in bright mode.
In addition, the new sensor incorporates a 16 Kbit programmable memory that can store lens shading correction data for four conditions at maximum settings, such as indoors and outdoors, daylight, and dusk. These settings can be changed with a simple command.
The sensor has a 1/2.7-inch optical size and a pixel pitch of 1.12 micrometers BSI. Sample shipments are scheduled to begin in September of this year.
