Abstract:
An information processing device includes an acquisition interface and a processor. The acquisition interface acquires a first detection image obtained by capturing an image of a plurality of target objects including a first target object and a second target object, which is more transparent to visible light than the first target object, using the visible light, and a second detection image obtained by capturing an image of the plurality of target objects using infrared light. The processor obtains a first feature amount based on the first detection image, obtains a second feature amount based on the second detection image, and calculates a third feature amount corresponding to a difference between the first feature amount and the second feature amount. The processor detects a position of the second target object in at least one of the first detection image and the second detection image, based on the third feature amount.

Abstract:
An image processing apparatus includes a first pixel output variation detecting section, a second pixel output variation detecting section, and a pixel correcting section. The first pixel output variation detecting section detects a variation between pixel outputs of the phase difference detecting pixel and the imaging pixel of the same color as the phase difference detecting pixel. The second pixel output variation detecting section detects a variation in pixel output between imaging pixels positioned in vicinities of the phase difference detecting pixel and the imaging pixel used by the first pixel output variation detecting section. The pixel correcting section corrects the pixel output of each phase difference detecting pixel based on results of the first and second pixel output variation detecting sections.
