1. An image processing device, coupled to a display device comprising a zoom lens, the image processing device comprising:
an image generation circuit, configured to generate a plurality of depth plane images with depth information, and a plurality of zoom control information respectively corresponding to the plurality of depth plane images, wherein the image generation circuit merges the plurality of depth plane images and the plurality of zoom control information according to an arrangement rule, so as to generate a merged image data; and
a multifocal length processing circuit, configured to decompose the merged image data according to the arrangement rule, so as to restore the plurality of depth plane images and the plurality of zoom control information corresponding to the plurality of depth plane images,
wherein the multifocal length processing circuit is further configured to determine a time at which the plurality of depth plane images which are restored are transmitted to the display device and a time at which the plurality of zoom control information which are restored are transmitted to the zoom lens according to a frame rate of the display device.
