Abstract: image processing system is capable of expressing a 3-D image correctly even if semitransparent images are complicatedly mixed in the 3-D image. A plurality of image generators each generate image data including a depth distance, from a predetermined reference portion, of an image to be expressed by the image data, and color information thereof. A merger specifies, e.g. sorts, the plurality of received image data in order of the depth distance included in each of the image data and merges the color information of the image data which is for expressing a first image whose depth distance is relatively long and the color information of the image data which is for expressing a second image in an overlapping manner over the first image.

Abstract: An image processing system includes a plurality of image generators and a merger which generates combined image data by merging image data produced by the image generators. The merger includes FIFOs for temporarily storing the image data received from the image generators, respectively. The merger further includes a synchronous signal generator for generating a first synchronous signal which causes the image generators to output the image data and further generating a second synchronous signal which causes the FIFOs to output the stored image data. The merger further includes a merging unit which receives the image data from the FIFOs in synchronization with the second synchronous signal and merges the received image data to produce combined image data.
