Toshiba Corp developed a CMOS image sensor that has a pixel size of 1.75μm and a pixel count of two millions and will release it at the end of January 2013.
The company expects that the CMOS sensor, "T4K28," will be used for cameras embedded in mobile devices such as mobile phones, smartphones and tablet computers.
The sensor contains an image signal processor, and various kinds of image processing can be carried out in the sensor. As output interfaces, it has both parallel and serial (CSI-2) types.
The pixel count of the sensor is 1,600 x 1,200 (1.92 million). The aspect ratio of output image is 4:3. The frame rates for full-size, 720p and VGA images are 15fps, 30fps and 60fps, respectively.
The power supply voltages of the analog, digital and I/O areas are 2.6-3.0V, 1.7-1.9V and 1.7-3.0V, respectively. The operating temperature of the sensor ranges from -20 to +60°C. The sensor will be shipped as a die, wafer and CSP (chip size package) in response to customer needs.
