Zusammenfassung:	A method, an image pre-processing apparatus, and a camera system for processing large images are provided. The method includes receiving from an image sensor an image frame at an image pre-processing apparatus, the image frame having a frame pixel resolution substantially equal to a sensor pixel resolution of the image sensor, dividing the image frame into first and second image subframes to be sequentially processed by an image signal processor, each of the first and the second image subframes having a subframe pixel resolution smaller than the sensor pixel resolution and a region in which the first and second image subframes overlap with each other. The subframe pixel resolution is predetermined by a processing capacity of the image signal processor, and the first and the second image subframes are consecutively processed by the image signal processor.
