PROJECTION IMAGE DISPLAY APPARATUS |
摘要 |
The projection image display apparatus includes a display element that emits image light generated by modulating light from a light source based, a pixel-shifter that shifts a pixel of a projected image by changing an optical path of the image light, a resampling circuit, a motion-interpolation image processing circuit, and a pixel-shift controller. The resampling circuit generates a plurality of sub-frame image signals having a resolution of the display element, by resampling an image signal having a resolution of the projected image. The motion-interpolation image processing circuit provides a motion-interpolation image process to the sub-frame image signals. The pixel-shift controller receives the sub-frame image signals having undergone the motion-interpolation image process. The pixel-shift controller drives the display element and the pixel shifter at a given timing based on the sub-frame image having undergone the motion-interpolation image process, and then displays the projected image, which involves pixel-shift, on a screen. |

1. A projection image display apparatus equipped with a display element that emits image light generated by modulating light from a light source based on a video signal, and a pixel shifter that shifts a pixel of a projected image by changing an optical path of the image light emitted from the display element, the projection image display apparatus comprising:
a resampling circuit for generating a plurality of sub-frame image signals having a resolution equal to a resolution of the display element, by resampling an image signal having a resolution equal to a resolution of the projected image; a motion-interpolation image processing circuit for providing a motion-interpolation image process to the sub-frame image signals output from the resampling circuit; and a pixel-shift controller for receiving sub-frame image signals having undergone the motion-interpolation image process and supplied from the motion-interpolation image processing circuit, wherein the pixel-shift controller drives the display element and the pixel shifter at a given timing based on the sub-frame image signals having undergone the motion-interpolation image process, and then displays the projected image, which involves pixel-shift and is emitted from the display element, on a screen. |
