1. A method performed by a controller for an image processing device, comprising:
receiving, via a first interface associated with the image processing device, a horizontal synchronization (HSYNC) signal associated with image data output by an image source, the first interface sampling the HSYNC signal responsive to transitions of a first clock signal so that each of the samples of the HSYNC signal represents a respective bit in a series of bits;
generating a local synchronization signal based at least in part on the series of bits;
receiving the image data via a second interface associated with the image processing device; and
capturing a frame of the received image data so that the beginning of the frame is aligned with an edge of the local synchronization signal.
