Patent ID: 8009934

Claim:
An image processing method performed by a data processing device comprising: an image input step of receiving input image signals having a first resolution; a resolution converting step of converting the input image signals obtained in the image input step into image signals having a second resolution, the second resolution being lower than the first resolution; and an output step of outputting output image signals corresponding to the image signals having the second resolution at a predetermined frame rate, wherein, in the resolution converting step the input image signals obtained in the image input step are divided into a plurality of regions and amounts of movement in the respective regions are detected and amounts of spatial decimation for the respective regions based on the amounts of movement detected are set, in the resolution converting step spatial decimation set for the respective regions is applied, the spatial decimation provides a visual effect that exhibits a resolution exceeding the second resolution when output image signals output in the output step are displayed at the predetermined frame rate, the foregoing steps performed on a device with a central processing unit.
