- FIG. 4 shows an example of a system configuration when performing multi-screen projection using two conventional projection type video display devices 90-1 and 90-2.
- the input video of each projection type video display device is different.
- the input video 1 of the projection video display device 90-1 provided from the information processing device 290, which is an external device is different from the input video 2 of the projection video display device 90-2.
- it is necessary to improve the quality of the joint by adjusting the black display and the white display of the joint between video 1 and video 2 displayed on the display surface by multi-screen projection.

- FIG. 6 is a non-overlapping projection of the video 1 of the projection type video display device 90-1 and the video 2 of the projection type video display device 90-2. This is the case when the function is ON.
- the conventional input video linkable modulation light function will be described as an example of a general function that varies the dimming amount in conjunction with the average luminance of the input video signal.
- the luminance value of the input video is in the range of 0 to 100. If the average luminance is 0, the dimming amount is 0%. If the average luminance is 100, the dimming amount is 100%. It is proportional to the average brightness.
- video 1 is 1000 pixels (0 to 1000 pixels position), and the average input luminance value is 25.
- the dimming rate by the modulatable light function of the projection display apparatus 90-1 is 25%. Therefore, in the relationship between the screen position of video 1 (position of 0 to 1000 pixels) and the output luminance value (no dimming function ⁇ 0.25), the luminance value is 0 when the screen position is 0 pixel, and the screen position However, at a position of 1000 pixels, the luminance value is 12.5, which is a characteristic that increases linearly.
- the dimming rate by the modulatable light function of the projection type video display device 90-2 is 75%. Therefore, in the relationship between the screen position of video 2 (position of 1000 to 2000 pixels) and the luminance value (no dimming function ⁇ 0.75), the luminance value is 37.5 at the position of 1000 pixels, and the screen At a position where the position is 2000 pixels, the luminance value is 75, which is a characteristic that increases linearly.

- the composite output luminance value changes from 12.5 to 37.5. That is, the synthesized output luminance value deviates from the target luminance value, and the luminance change at the screen position of 1000 pixels, which is a joint of images, is unnatural.
- FIG. 7 shows a case where the dimming function linked to the input video is turned off in the projection with the overlap of the video 1 of the projection video display device 90-1 and the video 2 of the projection video display device 90-2 (or the relevant If there is no function).
- the luminance value is 0 when the screen position is 0 pixel, and the luminance value is when the screen position is 800 pixels.
- the luminance value is 0 when the screen position is 1200 pixels, linearly increases when the screen position is 0 to 800 pixels, and decreases linearly when the screen position is 800 to 1200 pixels. It becomes a characteristic.
- the luminance value is 0 when the screen position is 800 pixels, and the luminance value is 60 when the screen position is 1200 pixels.
- the luminance value is 100.
- the screen position is in the range of 800 to 1200 pixels, the luminance value increases linearly.
- the screen position is in the range of 1200 to 2000 pixels, the luminance value increases linearly ( The characteristic increases more slowly than the range of 800 to 1200 pixels).
- both images are calculated by adjusting the output luminance value (adjusting the luminance of the overlapped part) so that the composite output luminance value becomes the target gradation while gradually decreasing the output luminance value toward the screen edge. .
- the target gradation display can be reproduced even with overlapping projection, and the joint between video 1 and video 2 should be in a natural state. Can do.
