1. A detection device comprising:
a processor; and
a memory coupled to or integrated with the processor,
wherein the processor is configured to:
in physical pixel disposition before and after movement of an image sensor having a plurality of physical pixels arranged in a first direction and a second direction intersecting the first direction, move the image sensor to a location at which a first physical pixel after movement to a location adjacent to a second physical pixel different from the first physical pixel before movement is positioned,
cause the image sensor to perform imaging before and after movement, and
detect a defective physical pixel from the plurality of physical pixels, based on a degree of difference in pixel values between image pixels corresponding to the second physical pixel before movement and the first physical pixel after movement, respectively, among a plurality of image pixels included in each of a plurality of images obtained by being captured by the image sensor.
