Diagonal 6.46 mm (Type 1/2.8) CMOS Solid-state Image Sensor with Square Pixel for

Color Cameras

Preliminary

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)

Features

◆ CMOS active pixel type dots

◆ Built-in timing adjustment circuit, H/V driver and serial communication circuit

◆ Input frequency: 74.25 MHz / 37.125 MHz

◆ Number of recommended recording pixels: 1920 (H) × 1080 (V) approx. 2.07M pixel

◆ Readout mode

All-pixel scan mode

720p-HD readout mode

Window cropping mode

Vertical / Horizontal direction-normal / inverted readout mode

◆ Readout rate

Maximum frame rate in Full HD 1080p mode: 120 frame / s

◆ Wide dynamic range (WDR) function

Multiple exposure WDR

◆ Variable-speed shutter function (resolution 1H units)

◆ 10-bit / 12-bit A/D converter

◆ Conversion gain switching (HCG Mode / LCG Mode)

◆ CDS / PGA function

0 dB to 30 dB: Analog Gain 30 dB (step pitch 0.3 dB)

30.3 dB to 63 dB: Analog Gain 30 dB + Digital Gain 0.3 to 33 dB (step pitch 0.3 dB)

◆ Supports I/O switching

CMOS logic parallel SDR output
