In order to appropriately control the image quality of an intended specific region in an image without delaying an encoding process, an image processing apparatus includes a determination unit configured to determine a specific region in a first image targeted for the encoding process on the basis of (a) a time difference between a first time associated with the first image and a second time associated with a second image in which an object has been detected by a detection unit before the encoding process is executed on the first image, and (b) information on a region corresponding to the object detected by the detection unit in the second image, and executes, on the first image, the encoding process of varying image quality between a region corresponding to the specific region determined by the determination unit, and any other region.
