Toshiba CMOS Image Sensor Targets Many Markets

News


Toshiba America Electronic Components, Inc. (TAEC) has revealed its first image sensor for the automotive, security and surveillance markets.

The device is a ¼ inch optical format VGA CMOS image sensor with high dynamic range (HDR) and fast frame rates.

Toshiba says its TCM5114PL VGA image sensor offers superior image quality, excellent colour reproduction, and video usage for up to ten years in 24 /7 operation mode. It is suited to display viewing of automotive telematic systems and surveillance cameras under various light and operating conditions.

"Toshiba is leveraging its industry-leading CMOS imaging technology into new markets with stellar results," says Andrew Burt, vice president of the Analog and Imaging Business Unit, System LSI Group at TAEC.

"The low-power consumption, and rich imagery enabled by this device in various light conditions will appeal to manufacturers in the automotive industry where most new car models feature on-board cameras and telematic systems that need to support crisp, clear dashboard display screens, as well as rear-view and surround-view camera systems, etc. Moreover, the high sensitivity at low light provided by this new VGA image sensor includes excellent light stabilisation features which are crucial for surveillance cameras operating in high-contrast, light-to-dark and day-to-night modes," adds Burt.

The TCM5114PL image sensor has a dynamic range of 100dB at 60 fps (frames per second) at full resolution output for VGA. With the combination of large 5.6 µm pixel, 640 (H) x 480 (V) array, integrated ISP and HDR functions, the TCM5114PL enables optimal images in low-light conditions, difficult with conventional sensors.

The high sensitivity of the sensor ( over 6V/lx.s) provides better quality images at very low luminescence levels. The TCM5114PL also facilitates excellent colour reproduction through its primary Bayer colour filter.

Other features of the device include a single 3.3V source power supply, which reduces component count and board real estate, lens shading correction, picture flip (both horizontal and vertical), auto white balance, auto luminance (exposure) control, auto flicker detection and correction, defect pixel corrector, programmable gamma correction standby mode (software standby), and power-down mode (hardware standby).

The TCM5114PL has both a digital and analogue (NTSC/PAL) interface so it can connect to currently available display panels. The device supports YUV422/RGB565/ RGB888/ RAW10/RAW12 data formats.

Samples of the TCM5114PL VGA image sensor are currently available. Mass production is scheduled for March 2013. Sample
