Diagonal 6.46 mm (Type 1/2.8) Square Pixel Array Color CMOS Image Sensor
Back-Illuminated CMOS image Sensors with Improved Visible Light and Near Infrared Sensitivity that Support 1080p
Sony has developed the approx. 2.13M effective pixel backilluminatedCMOS image sensors IMX290LQR and IMX291LQR with improved sensitivity in the visible-light and near infrared light regions for industrial applications.
A new 2.9 μm-square unit pixel has been developed that combines a back-illuminated structure with technology for improving near infrared sensitivity to further enhance picture quality at low illumination while at the same time realizing Full HD cameras for industrial applications. This realizes two or more times the sensitivity in the visible-light region and three or more times the sensitivity in the near infrared light region than that of the existing Sony product (IMX236LQJ)*1. In addition, two types of WDR (Wide Dynamic Range) technology are also provided to further improve imaging performance.
The new lineup includes the two types of the IMX290LQR, which has the DOL(Digital overlap loop) -WDR function and the IMX291LQR, which does not have the DOL-WDR function. Back-Illuminated Structure + Improved Sensitivity in the Near Infrared Light Region
Back-Illuminated Structure + Improved Sensitivity in the Near Infrared Light Region
Good sensitivity characteristics at low illumination and in the near infrared light region are a required performance of cameras
for industrial applications. These new image sensors use a back-illuminated structure and also have an expanded photodiode area, which simultaneously improve sensitivity in both light regions compared to the existing front-illuminated structure.
In addition, the new image sensors realize improved sensitivity characteristics two or more times in the visible-light region and three or more times in the near infrared light region (850 nm) compared to the existing Sony product (IMX236LQJ) with the same pixel size and increased sensitivity in the near infrared light region (Photograph 2).
WDR Function
The IMX290LQR supports both multiple exposure and DOL(Digital overlap loop)-type WDR functions. (The IMX291LQR supports only the multiple exposure-type WDR function.)
The multiple exposure-type WDR function outputs one set of two or four frames with different exposure times. In this case, the gain can also be set separately for each frame in addition to the exposure time.
The DOL(Digital overlap loop)-type 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.
Versatile interface
The IMX290LQR and IMX291LQR are equipped with three different types of output interface (low-voltage LVDS serial, MIPI CSI-2, CMOS parallel) to meet diverse needs. The low-voltage LVDS serial interface has a maximum output data rate of 445.5 Mbps/ch and the number of output channels can be selected from 2ch, 4ch or 8ch. The MIPI CSI-2 interface has a maximum output data rate of 891 Mbps/lane and the number of output channels can be selected from 2 lanes or 4 lanes. The CMOS parallel interface has a maximum output data rate of 74.25 Mpixels/s.
