Abstract

PURPOSE:To grasp the general image by decreasing the amount of information of an image, by displaying the resolution of a specified area of a display surface high, and displaying the resolution of other areas low. CONSTITUTION:When an observer 5 is looking in the direction of an original point O, with the original point O as the center, for example, an area O1 is displayed at a high resolution, an area O2 at a medium resolution, and an area O3 at a low resolution. That is, the image information is thinned out by a control device 7 controlling an input signal modulating device 3, according to the information from a position sensor 6, which detects the traveling of the direction of the line of sight by a magnetic sensor 6b attached to the observer 5's head. After the thinned-out signal is set to a display side signal demodulation device 4, it is displayed on a display surface 1b of a display device 1, and when the observer 5 turns to the direction of the original point O', the areas of high, medium, and low resolutions are traveled to the areas O1'-O3'. Thus the observer 5 can always have the area of high resolution within his visual field.

[Embodiment] FIG. 1 is a system configuration diagram for explaining an embodiment of the image display method of the present invention. In this figure, numeral 1 denotes a display device such as a projector, CRT, etc. (the projector is shown here), which consists of a projector 1a and a display surface 1b, and has uniform resolution over the entire surface in terms of hardware. Reference numeral 2 denotes an image input device such as a camera or a VTR, and 3 a human power signal conversion device, which outputs image information of a specific portion such as the center of the screen at a high resolution, and thins out the other portions to a lower resolution.

Now, in this example, if it is assumed that the area o1 has high resolution and the area 02 has low resolution, then when the observer 5's viewpoint is at the center of area 01, the origin 0, the area Even if the resolution of the 02 part is low and the image is vague, it doesn't bother me that much. Note that in order to realize the present invention, in addition to the method of changing the display resolution using software, an input device and a display device that have a high resolution of a specific part may be used using hardware. In this case, special conversion and demodulation of the signal becomes unnecessary.

FIG. 3 is a system configuration diagram for explaining still another embodiment using a special camera-type human-powered imaging device that has high resolution only in the vicinity of the center in terms of hardware. In this figure, 2' is a camera-type image input device whose resolution is high only near the center, and 8 and 9 are moving devices for the projector 1a and the image input device 2', respectively.

In this embodiment, the control device 7 operates the moving device 9 according to information from the position sensor 6 detected by the magnetic sensor 6b attached to the head of the observer 5, and the image input device 2' is controlled by the observer 5. The center of the projector 1a is directed toward the point O' toward which the observer 5 is facing by operating the moving device 8 while keeping the display surface 1b fixed. Compared to the software method shown in FIG. 2, this method does not require the input signal converting device 3, but requires mechanical driving of the projector 1a and the human-powered image device 2'. Also, in this case, if you send, for example, 1/2 of the length in both the vertical and horizontal directions at a high resolution, and the rest at 1/2 of that resolution, the image information will be smaller than when the entire length is sent at a high resolution. Reduced to 5/8.
