A hybrid image sensor is a digital multi-line scan CMOS image sensor that is high speed, low noise, and optimised for monochrome and colour automatic optical inspection activities.
This comprises check scanning, manufacturing electronics, food sorting, print inspection, and medical (OCT, tissue diagnostics etc.)Red, green, and blue (RGB) tristimulus values are produced by the image sensor of a digital camera and are proportional to radiance. Scientists refer to these numbers as linear-light.
However, most imaging systems use a nonlinear transfer function called gamma correction to encode RGB tristimulus values, simulating the perceptual response of human vision. The R’G’B values used by the majority of image coding algorithms are not proportional to intensity; instead, a perceptually driven nonlinearity is imposed, as indicated by the primes in the notation.
The Global Hybrid image sensor market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
A new hybrid image sensor from STMicroelectronics allows driver-monitoring systems (DMS) to fully monitor the interior of the vehicle, including the driver and all passengers, in addition to monitoring the driver’s level of attentiveness.
New applications such as passenger safety-belt checks, vital-sign monitoring, child-left detection, gesture recognition, and high-quality video/picture recording will be made possible by the new hybrid rolling and global-shutter image sensor.
The new sensor, the VD/VB1940, combines high-dynamic-range (HDR) colour imaging with infrared sensing’s sensitivity and resolution in a single element.
Both rolling-shutter and global-shutter modes are alternately supported by the hybrid image sensor when taking pictures. Both the near-infrared (NIR) images generally collected by ordinary DMS sensors and HDR colour photos for occupant monitoring systems (OMSs) are captured by the 5.1-megapixel image sensor in a 1/2.5-inch optical format.
Driver head and eye movements can be analysed using NIR imaging in all kinds of lighting. In order to synchronise with the infrared LED emitter and capture fast-moving scenes without motion blur, the sensor takes NIR photos in global shutter mode. The VD/VB1940 is said to offer optimal color-imaging performance in rolling-shutter mode, which reads pixel data row by row. Up to 60 frames per second can be delivered.
