Claim Text:
1. A three-dimensional image processor comprising: a discriminator that determines whether or not a read position of an input video signal is to be modified according to portrait or landscape orientation of an image based on the video signal and according to an identification signal indicating portrait or landscape orientation when a display unit displays the image based on the video signal, and generates a discrimination signal indicating whether or not the read position is to be modified; a parameter generator that generates a parameter indicating an aspect ratio of the image to be displayed by the display unit based on the video signal; a parallax generator that generates shift amounts for generating a left-eye signal and a right-eye signal based on the video signal; a frame memory unit that temporarily stores the video signal; a controller that controls the read position of the video signal stored in the frame memory unit; and a motion vector parameter generator that determines a motion vector by a difference of signals between frames of the video signal, wherein the controller controls the read position of the video signal based on the parameter, the shift amounts and the motion vector when the discrimination signal received from the discriminator indicates that the read position is to be modified, and controls the read position of the video signal based on the shift amounts and the motion vector when the discrimination signal received from the discriminator indicates that the read position is not to be modified, and the controller controls the read position of the video signal based on the parameter and the shift amounts when the discrimination signal received from the discriminator indicates that the read position is to be modified, and the controller controls the read position of the video signal based on the shift amounts when the discrimination signal received from the discriminator indicates that the read position is not to be modified.
