ABSTRACT:
In an image processing device, a scene-change detection unit captures first data of first pixels constituting a first picture and second data of second pixels constituting a second picture with the first and second pixels thinned out, and detects a scene change in the first picture based on differences between the first and second data, where the second picture immediately precedes the first picture. A transfer control unit controls operations of reading out at intervals from a storage device data of groups of a predetermined number of pixels consecutively arranged along a horizontal direction in at least the second picture, and transferring the data of the groups to the scene-change detection unit through a data bus, where the predetermined number corresponds to the maximum number of pixels which can be concurrently transferred through the data bus, or an integer multiple of the maximum number.
