In an embodiment of the present disclosure, the X-ray detecting system comprises a processing unit for processing the pixel signals, wherein the processing unit comprises a frame summing unit configured to, for a pixel of the pixel array, compare the pixel values of the acquired frames that correspond to that pixel for detecting a pixel value in those frames that was adversely affected by a direct hit of that pixel by an X-ray photon during said single exposure, and generate a pixel value for that pixel in dependence of the pixel values of the acquired frames and detected pixel value for that pixel.

The invalid pixel detection unit 32 detects an invalid pixel from a non-polarized image and a plurality of polarized images for different polarization directions obtained by performing image pickup using the polarization image pickup unit 20. For example, the invalid pixel detection unit 32 detects a saturated pixel having a pixel value larger than a preset saturation detection threshold and a black-crushed pixel having a pixel value smaller than a preset black crushing detection threshold as invalid pixels from a non-polarized image. The polarization information generation unit 33 performs processing of generating polarization information on the basis of the non-polarized image and polarized images and switches the processing of generating the polarization information depending on the detection result of the invalid pixels in the invalid pixel detection unit 32, so as to generate the polarization information without using the invalid pixels. Correct polarization information can be acquired.

The vision sensor generates a plurality of events in which an intensity of light changes and generates a plurality of timestamps depending on times when the events occur. In addition, the processor may regenerate a timestamp of a pixel where an abnormal event occurs, based on temporal correlation of the events.
