Patent ID: 8279339

Claim:
A projection display comprising: a frame rate conversion means for selectively performing a first frame rate conversion process or a second frame rate conversion process, the first frame rate conversion process increasing a frame rate by interpolating an intermediate image frame between image frames of an input video signal, the second frame rate conversion process increasing the frame rate by repeatedly outputting each image frame of the input video signal along a time axis; an image process means for selectively performing a black insertion process or a pair-frames gamma process, and outputting a result as a pair of consecutive image frames, the black insertion process inserting a black frame between image frames of the input video signal, the pair-frames gamma process performing a pair of gamma conversion processes, each having different gamma characteristics, to a series of image frames in the input video signal; a projection display means for projecting and displaying an image on the basis of the video signal processed by the frame rate conversion means or the image process means; and a control means for controlling the frame rate conversion means or the image process means according to a selected operation on a menu screen, the control means having a user interface function for displaying the menu screen which enables a user to select the first or the second frame rate conversion processes by the frame rate conversion means, the black insertion process, or the pair-frames gamma process by the image process means, wherein the control means performs the user interface function so that the black insertion process or the pair-frames gamma process by the image process means is selected with priority over the first frame rate conversion process by the frame rate conversion means.
