Diagonal 6.46 mm (Type 1/2.8) CMOS Solid-state Image Sensor with Square Pixel for
Color Cameras
IMX291LQR-C
Description
The IMX291LQR-C is a diagonal 6.46 mm (Type 1/2.8) CMOS active pixel type solid-state image sensor with a
square pixel array and 2.13 M effective pixels. This chip operates with analog 2.9 V, digital 1.2 V, and interface 1.8 V
triple power supply, and has low power consumption. High sensitivity, low dark current and no smear are achieved
through the adoption of R, G and B primary color mosaic filters. This chip features an electronic shutter with variable
charge-integration time.
(Applications: Surveillance cameras, FA cameras, Industrial cameras)
