Canon 120 Megapixel CMOS Sensor

Ultra-High Resolution CMOS Sensor

The 120MXS is an ultra-high resolution CMOS sensor with 13272 x 9176 effective pixels. It has a size equivalent to APS-H (29.2mm x 20.2mm), and a square pixel arrangement of 2.2μm x 2.2μm with 122 million effective pixels. Ultra-high-resolution is made possible by parallel signal processing, which reads signals at high speed from multiple pixels. All pixel progressive reading of 9.4 fps is made possible by 28 digital signal output channels. It is available in RGB, or in monochrome with twice the sensitivity. 

Ultra High Resolution and Speed 

By incorporating close to the same number of pixels as receptors in the human eye, the 120MXS captures remarkable detail 60 times greater than full high definition standards. By sharing a floating diffusion capacitance between four pixels instead of one, less space is required for the readout circuitry. This allows for larger photodiode sizes with an improved signal-to-noise ratio, without the tradeoff of long readout speeds. 

Readout Position and Frame Rate Control 

The readout start position can be specified to allow flexibility in both frame rate and resolution depending on the application and required performance level. This feature allows the selection of a region of interest scalable to the final application requirements. 

Optimized Pixel Design 

The sensor’s small pixels bring the potential for light to leak from pixel to pixel, which is known as crosstalk. When this happens, it can create color shading and inaccurate color representation that degrades image quality. To mitigate crosstalk, a wire layer has been incorporated into the sensor structure between each pixel. This creates a boundary that surrounds the pixel and keeps light from leaking between them.
