Canon Develops HDR Sensor and Improves its Older Sensors

PRNewswire: Canon Inc is pursuing development of the 3U3MRXSAAC, a 2.8MP, 1/2.32-inch CMOS sensor for HDR imaging in -40C to 105C temperature range.

"As Canon evolves in the sensor market, we are dedicated to utilizing our expertise to develop products built to meet current growing market trends," said Kazuto Ogawa, president and COO, Canon U.S.A., Inc. "The 3U3MRXSAAC CMOS sensor under development reflects the continuation of our business strategy that leverages the high-quality imaging technology Canon is able to achieve."

The 3U3MRXSAAC CMOS sensor is expected to achieve a DR of 120 dB at low noise levels. Even during normal drive operation, the sensor can achieve a dynamic range of 75 dB—greater than the sensors on many conventional digital cameras.

Additionally, the 3U3MRXSAAC CMOS sensor will also be capable of operating in environments with extreme temperatures ranging from -40C to 105C. Typically, in high-temperature conditions, the increase in dark current noise can affect the quality of the image. However, the 3U3MRXSAAC CMOS sensor will be equipped with functionality that helps correct black levels in real-time to help maintain high image quality.

The 3U3MRXSAAC CMOS sensor will feature a pixel size of 3.2 μm x 3.2 μm and a frame rate of up to 60 fps (30 fps during HDR drive operation). The sensor will be compatible with the MIPI CSI-2 interface.

PRNewswire: Canon re-announces its 35MMFHDXSMA, a 19um-large pixel 2.7MP sensor, and 120MXSI, a 2.2um 120MP APS-H sized sensor. Both sensors have been already presented earlier, albeit with slightly different part codes. It's not immediately clear what has changed in these new sensors.
