To provide an image processing device capable of efficiently detecting an object, and further to provide an image processing system, a camera, a camera system or the like.
An image processing device 100 includes: an image acquiring section 110 for acquiring infrared image data; a region setting section 120 for setting boundary lines that divide an image region into a plurality of regions with respect to the image region on the basis of the infrared image data acquired by the image acquiring section 110 and for setting at least one region out of the plurality of regions divided by the boundary lines to a pixel density changing region ARMD; and a processing section that performs a process for reducing pixel density of the infrared image data of the pixel density changing region ARMD, performs a detection process of an object on the basis of the infrared image data of the image region including the pixel density changing region ARMD and generates image data for display on the basis of a result of the detection process.
