Sony’s polarization image sensor (polarization sensor) has a multi-directional polarizer which is formed on top of the photodiode of the image sensor chip*1. In addition to capturing brightness and color*2, this image sensor can also capture polarization information that cannot be detected by a normal image sensor. This sensor can be used in many applications in the industrial field, such as inspection when visibility and sensing are difficult.

Four directional polarizer is formed on the image sensor

Sony Semiconductor Solutions’ polarization sensor can capture a four directional polarization image in one shot by the four directional polarizer (Fig.1). It can calculate the direction and degree of polarization (DoP) based on the intensity of each directional polarization. Together with subsequent signal processing, it can capture the polarization information*3 in real time*4.

Global Shutter function

Industrial applications require imaging of fast-moving objects. However, existing CMOS image sensors are unable to accurately identify fast-moving objects, due to the focal plane distortion, which is caused by the rolling shutter function. The IMX250MZR/MYR, IMX264MZR/MYR, IMX253MZR/MYR address this issue by providing an analog memory inside each pixel and realizing the global shutter function to enable high-picture-quality without focal plane distortion.

High Frame Rate

The column-parallel A/D conversion technology of Sony's CMOS image sensors is used to realize high-speed imaging of up to 163.4frame/s (ADC 8 bit) for the IMX250MZR/MYR, 35.7 frame/s(ADC 12 bit) for the IMX264MZR/MYR and 68.3frame/s (ADC 8 bit) for the IMX253MZR/MYR. Increased processing speed is used for industrial applications.

ROI mode and trigger mode

IMX250MZR/MYR, IMX264MZR/MYR, IMX253MZR/MYR, are equipped with variety of functions necessary for industrial applications, such as ROI Mode and Trigger Mode. ROI Mode crops required areas. Up to 8 × 8 = 64 locations can be set with IMX250MZR/MYR, and 1 location with IMX264MZR/MYR. In addition to setting 8 × 8 = 64 locations, IMX253MZR/MYR provides greater freedom of specifying regions and allows overlap of specified regions. Various exposure methods are provided with the trigger mode, which controls the exposure time using an external pulse.
