Abstract: The present disclosure relates to detection of crosstalk included in images output from an image sensor. An information processing apparatus includes a processor configured to process images output from an image sensor of an imaging apparatus that captures images having different characteristics by splitting a pupil. The processor is configured to acquire a first image that is captured by the imaging apparatus under a first imaging condition and that is output from the image sensor, acquire a second image that is captured by the imaging apparatus under a second imaging condition different from the first imaging condition and that has the same characteristic as the first image among the images output from the image sensor, and detect crosstalk included in the images based on a correlation between feature amounts of the first image and the second image.

Abstract: An image data processing device processes image data captured by an imaging device that includes an optical system which spectrally separates incident light and polarizes light with the spectrally separated wavelengths, and emits the polarized light in a specific direction and an imaging element including a plurality of pixel sets each of which includes different types of polarizers. The image data processing device performs processes of: acquiring the image data; detecting a pixel whose pixel value is out of a predetermined range as an abnormal pixel from the acquired image data; correcting a pixel value of the abnormal pixel on the basis of pixel values of peripheral pixels in a case in which the abnormal pixel is detected; and generating images of the spectrally separated wavelengths from the image data in which the pixel value of the abnormal pixel has been corrected when the abnormal pixel is detected.
