Sony 2MP Starvis CMOS sensor with DOL HDR. Diagonal 6.46mm (1/2.8")
Part Number: IMX290LQR
Pixel size: 2.9 µm (H) × 2.9 µm (V)
Back-Illuminated CMOS image Sensors with Improved Visible Light and Near Infrared Sensitivity
With STARVIS Technology realizes high picture quality in the visible-light and near infrared light regions.
Other Sensor that With STARVIS: IMX274(8MP/4K) IMX291(1080P) IMX226(12MP/8MP/4K) IMX178(5MP) IMX123(3MP/1080P) IMX124(3MP/1080P)
The difference of IMX290 and IMX291:
IMX290 supports DOL ((Digital Overlap) -WDR function, IMX291 does not support DOL-WDR.
Both IMX290 and IMX291 supports multiple exposure-type WDR function.
DOL-WDR function outputs the data for up to three frames with different storage times line by line. By performing special signal processing with an ISP (Image Signal Processor) or other device at the image sensor rear-end, this enables improvement of picture quality under low illumination compared to the multiple exposure-type WDR function.
