Patent ID: 8508528

Claim:
An image signal processing apparatus, comprising: a receiving unit that receives a display signal including an image signal containing both a two-dimensional image and a three-dimensional image, and region information defining in a predetermined unit a first region to display the two-dimensional image and a second region to display the three-dimensional image when displaying the image indicated by the image signal, and separates the image signal and the region information from the received display signal; a display control unit that generates a first display control information for controlling rendering positions of the first region and the second region in the image signal according to the region information, and a second display control information for selectively displaying a three-dimensional image in a region corresponding to the rendering position of the second region on the display screen based on the region information separated by the receiving unit; and a processing unit that generates a display image signal indicating where the first region and the second region are arranged according to the first display control information generated by the display control unit and the image signal separated by the receiving unit, wherein the receiving unit separates timing information from the received display signal, the display control unit generates a control signal based on the timing information separated by the receiving unit, and the processing unit outputs the display image signal at a timing controlled by the control signal generated by the display control unit so that the display image signal is synchronized with the timing information separated from the received display signal, and the receiving unit separates blending object information and blending ratio information from the received display signal, the blending object information specifying an overlap region where the first region and the second region overlap, and the blending ratio information specifying processing to be carried out in the overlap region, and the display control unit generates the first and second display control information in accordance with the blending object information and the blending ratio information.
