※ 2.9 μm平方单位像素背光结构
※ 高灵敏度特性(是现有产品的2倍或以上)
※ 提高了近红外光区域的灵敏度(是现有产品的三倍或更多)

背光结构+提高灵敏度在近红外光区域
在低照度和近红外光区域良好的灵敏度特性是工业应用相机的要求性能。这些新的图像传感器采用背光照明结构，并有一个扩大的光电二极管面积，与现有的前光照明结构相比，这同时提高了两个光区域的灵敏度。
此外,新的图像传感器实现改善灵敏度特性两个或两个以上的时间在可见光区域和三个或更多时间在近红外光区(850nm)相比,现有的索尼产品具有相同像素大小(IMX236LQJ)和近红外光区敏感度增高(照片2)。
WDR (Wide Dynamic Range)的功能
IMX290LQR同时支持多重曝光和DOLtype WDR功能。(IMX291LQR只支持多重曝光型WDR功能。)多曝光型WDR功能输出一组不同曝光时间的两帧或四帧。在这种情况下，除了曝光时间外，每帧的增益也可以单独设置。
dol型WDR函数以不同的存储时间逐行输出最多三帧的数据。通过在图像传感器后端使用ISP(图像信号处理器)或其他设备进行特殊的信号处理，与多曝光型WDR功能相比，可以在低照度下改善图像质量。
通用的接口
IMX290LQR和IMX291LQR配备了三种不同类型的输出接口(低压LVDS串行、MIPI cgi -2、CMOS并行)，以满足不同的需求。低压LVDS串行接口的最大输出数据速率为445.5 Mbps/ch，输出通道的数量可以从2ch、4ch或8ch中选择。MIPI CSI-2接口的最大输出数据速率为891Mbps/lane，输出通道数可选择2通道或4通道。CMOS并行接口的最大输出数据速率为74.25万像素/秒。

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 backilluminated CMOS 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) -WDR function and the IMX291LQR, which does not have the DOL-WDR function.

※ Back-illuminated structure with 2.9 μm-square unit pixel
※ High sensitivity characteristics (two or more times that of the existing product)
※ Improved sensitivity in the near infrared light region (three or more times that of the existing product)
※ Supports WDR (multiple exposure WDR, DOL-WDR)
※ Versatile interface (CMOS parallel, low-voltage LVDS serial, MIPI CSI-2)
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 (Wide Dynamic Range) Function
The IMX290LQR supports both multiple exposure and DOLtype 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-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.
IMX291 is full HD 1080P resolution with SONY IMX291 CMOS image sensor.
The IMX291 is a STARVIS back-illuminated CMOS image sensors. The Starvis technology features a high sensitivity and realizes high picture quality in the visible-light and near infrared light regions. The sensor is also equipped with Sony’s Exmor R technology which provides an enhanced imaging performance especially a higher sensitivity and low noise. The IMX291LQR is a color CMOS sensor with a diagonal of 6.46mm (type 1/2.8) with a pixel size of 2.9μm square and 2.13MP effective resolution. The IMX291LQR has a paralell, Serial LVDS and a MIPI output and achieves a maximum frame rate of 30fps at full resolution.
