US 11,689,710 B2 · Image processing device, image processing method and 3D image generation system

Abstract

An image processing device, including an image generation circuit and a multifocal length processing circuit, is provided. The image generation circuit generates multiple depth plane images with depth information and multiple corresponding zoom control information, and merges the multiple depth plane images and the multiple zoom control information according to an arrangement rule, to be a merged image data. The multifocal length processing circuit is configured to decompose the merged image data to restore the multiple depth plane images and the corresponding multiple zoom control information according to the arrangement rule, and to determine a time at which the restored multiple depth plane images are transmitted to a display device and a time at which the restored multiple zoom control information are transmitted to a zoom lens according to a frame rate of the display device. The disclosure also provides an image processing method and a 3D image generation system.
