The IMX661 from Sony Corporation is a 127 MP CMOS Solid-State Image Sensor that has a pixel size of 3.45 × 3.45 μm. It has a resolution of 13400 (H) x 9528 (V) pixels with a maximum frame rate of 21.8 FPS in all-pixel scan mode (127 MP). This image sensor requires a supply voltage of 3.3 V (analog), 1.2 V (digital), or 1.8 V (interface) and supports 11/12/14 bit ADC resolution.
The IMX661 is based on Sony's original global shutter pixel technology "Pregius” which enables the capture of distortion-free images. It uses a chip-on-wafer process where chips with certain functions are stacked on top of the pixel wafer, allowing for optimal positioning and processing functionality of the ADC without increasing the size. The sensor has Sony’s scalable low voltage signaling feature with an embedded clock (SLVS-EC) high-speed interface standard to make the output interface faster.
The IMX661 is equipped with a range of signal processing capabilities such as trigger synchronization for controlling imaging timing during high-speed inspections, Region of Interest (ROI) which reduces post signal processing load by only reading out the required regions, gradation compression which reduces data volume while outputting required information, multi-exposure which detects the trajectory of moving objects, the short exposure time for blur-free imaging of objects moving at high speeds and pixel binning readout which enhances sensitivity in low luminance situations. It also has a built-in timing adjustment circuit, H/V driver, and serial communication circuit and has CDS/PGA and pulsed output function for the exposure period. It is available in an LGA package that measures 75 x 63.6 mm and is ideal for industrial applications.
