Patent ID: 8564645

Claim:
A signal processing device comprising: an image analysis portion that analyzes content of an input image; a distance information acquisition portion that acquires distance information between a viewer who views a screen on which the input image is displayed and the screen; and a stereoscopic image generation portion, in which the image analysis portion includes (i) a detection portion that detects a size of an object included in the input image, and (ii) a distance calculation portion that calculates, from the size detected by the detection portion, a distance between a position of the object in a virtual space and the viewer, in which the position of the object in the virtual space represents a position at which the object is assumed to be located beyond the screen in a direction away from the viewer so that the position of the object in the virtual space is different from a position of the screen such that the calculated distance between the position of the object in the virtual space and the viewer is larger than the distance between the viewer and the screen, and in which the stereoscopic image generation portion generates a stereoscopic image from the original input image using (i) the distance between the position of the object in the virtual space and the viewer that is calculated by the distance calculation portion, (ii) the distance information acquired by the distance information acquisition portion, and (iii) information about the specification of the screen in the horizontal direction.
