Aptina patented Dual Conversion Gain (DCG) technology and multi-exposure HDR
(High Dynamic Range) imaging techniques, the MT9M033 HD megapixel image sensor
uniquely offers both HDR and excellent low light sensitivity for digital camera
manufacturers. DCG technology allows
programmable conversion gain adjustment globally across all pixels to match the
overall light level in the scene automatically in day or night mode. When
coupled with a true correlated double sampling technique, this new HD image
sensor can achieve a low read noise of <2e- rms and leading-edge quantum
efficiency of more than 60 percent-unachievable by conventional CMOS image
sensors today. Today, high-definition (HD) video has become the prevalent
viewing standard. However, capturing
high-quality 60 frames per second (fps) HD video in all lighting conditions -
ranging from very high-contrast to very dark scene - with low-power consumption
is extremely challenging. Historically,
megapixel sensors could provide HDR or excellent low light sensitivity, but not
both. With recent sensor developments
from Aptina, camera designers no longer need to compromise between performance,
HDR, and low-light sensitivity to create a true HD camera. Aptina implemented a multi-exposure technique
that increases the dynamic range by 25 percent over typical high contrast
scenes and insures that one can take a good picture in any lighting condition.
Comparatively, the conventional lateral overflow method, divides the pixel
full-well into multiple parts, limiting light collection. Aptina's system
allows complete utilization of each pixel's full well capacity, making this
multi-exposure method far superior in terms of controlling blooming. Addressing motion artifacts that typically
plague the market's HDR cameras, Aptina added special readout and processing
schemes to the MT9M033 to eliminate this problem.
