Abstract
A shading device comprises: a shading member formed using a dimming glass plate capable of changing light transmittance, the shading member having a plate shape; a display apparatus being capable of transmitting light and disposed on a surface of the shading member, the surface being to face an operator during use of the shading member, in such a manner that a display portion faces the operator; an image pickup device to pick up, as an image, a region which an opposite surface of the surface faces, and generate image pickup data; a data processing circuit to generate display image data to be displayed on the display portion during use of the shading member, based on the image pickup data generated by the image pickup device; and a switch to change light transmittance of the dimming glass plate.
Claims20
A shading device comprising:
- a shading member formed using a dimming glass plate that is capable of changing light transmittance, the shading member having a plate shape;
- a display apparatus being separate from the dimming glass plate and capable of transmitting light, wherein the display apparatus is disposed on a surface of the shading member, the surface being to face an operator during use of the shading member, in such a manner that a display portion faces the operator;
- an image pickup device to pick up, as an image, a region which an opposite surface of the surface faces, and generate image pickup data;
- a data processing circuit to generate display image data to be displayed on the display portion during use of the shading member, based on the image pickup data generated by the image pickup device;
- a switch to change light transmittance of the dimming glass plate;
- a detector to detect a position of the shading member;
- a control circuit to control the display apparatus to an OFF state when the light transmittance of the dimming glass plate is greater than or equal to a given reference value, and control an ON/OFF state of the display apparatus based on a result of detection of the detector when the light transmittance of the dimming glass plate is less than the given reference value;
- and
- a sensor capable of detecting intensity of light, the sensor being provided on each of the surface and the opposite surface of the shading member, wherein
- the control circuit controls the display apparatus to the OFF state in a case where a difference in output between the sensor being provided on the surface of the shading member and the sensor being provided on the opposite surface of the shading member is smaller than a given reference value, and
- the shading device is configured to display, with the display apparatus, a view being obstructed by the dimming glass plate when the dimming glass plate obstructs a light illuminating the shading member.
