Image sensor with 5-megapixel hybrid shutter and on-chip RGB-IR intelligence
The VB1943 5-megapixel (MP) RGB-IR CMOS image sensor from STMicroelectronics adds a hybrid shutter and on-chip RGB-IR intelligence for seamless 5MP color and infrared (IR) imaging without the need for additional components.
The dual 2.25µm global and rolling shutter offers artifact-free clarity with on-chip high dynamic range (HDR), in addition to optimizing light performance.
For embedded vision applications, the VB1943 image sensor simplifies computer vision with on-chip processing and MIPI CSI-2 output, with streamlined integration and lower power consumption. Using 3D stacking and patented processes, the VB1943 offers outstanding performance in the 940nm near infrared (NIR) and visible spectrum. Global shutter mode is able to capture up to 100 frames per second (fps) when operating at 2560 x 1984 resolution.
In rolling shutter mode, advantages are offered by the low dark noise capability. The VB1943 image sensor is able to compress the 18-bit HDR mode down to 12 or 10 bits using customizable piecewise linear (PWL) compression.
The integrated advanced image signal processor (ISP) is used to process the RGB-NIR input image, and to reconstruct a full-resolution NIR smart upscaled monochrome image or a 2×2 color Bayer image which is NIR depolluted.
With an NIR light source, the global shutter mode benefits computer vision applications by significantly reducing the system power consumption that is needed to drive illumination. Programmable general-purpose input/output (GPIOs) pins control external illuminators, and output is synchronized with sensor integration periods, and pulse-width modulation (PWM) control.
