Panasonic Develops New 123dB Simultaneous-Capture WDR Technology for High-Precision Imaging
Panasonic announced Wednesday that it has developed industry’s first 123dB simultaneous-capture wide dynamic range technology, using an organic photoconductive film (OPF) CMOS image sensor. The new technology brings 100 times improvement over conventional results, enabling high-speed, high-precision, and wide-dynamic-range imaging and sensing.
The OPF CMOS image sensor features charge-storage and photoelectric-conversion functions which help prevent overexposure in bright situations without time distortion against moving object. Which means, a sharp and texture-rich image can be reproduced even in dark situations.
Panasonic’s wide-dynamic-range technology includes the following technologies:
- The OPF CMOS Image Sensor Design Technology, in that, photoelectric-conversion part and a circuit part can be designed independently.
- Dual-Sensitivity Pixel Technology that is provided with two sensitivity detection cells (one for brightness; one for darkness) in each pixel, taking advantage of a high-saturation performance and flexibility of a sensitivity setting of OPF CMOS image sensor, in order to achieve simultaneous-capture wide dynamic range.
- Capacitive-Coupled Noise Canceller Technology that can cancel pixel reset noise, in order to improve S/N characteristics of imaging dark objects.
Panasonic is set to showcase some part of this new technology at the International Solid-State Circuit Conference (ISSCC) 2016 which is to be held in San Francisco on January 31 – February 4, 2016.
