TRANSMISSIVE DISPLAY APPARATUS AND LIGHT CONTROL SHADE FOR TRANSMISSIVE DISPLAY APPARATUS

摘要

A transmissive display apparatus allows see-through observation in which video light and outside light are superimposed on each other for visual recognition of the superimposed light and further allows a light control shade to control the outside light by changing the outside light transmittance of the light control shade in accordance with a change in quantity of the outside light. In this case, in particular, when a decrease in the outside light quantity is detected with an outside light sensor, which is the outside light detection section, a light quantity control section of a primary control section performs quick response control in which the transmittance of the light control shade is quickly adjusted (outside light quantity is controlled).

主权项

1. A transmissive display apparatus that superimposes video light and outside light on each other and allows visual recognition of the superimposed light, the apparatus comprising:
a display section that displays the video light; a light control shade that is so provided as to face the display section and controls the outside light; an outside light detection section that detects the outside light; and a light quantity control section that controls transmittance of the light control shade based on a result of the detection performed by the outside light detection section, wherein the light quantity control section performs quick response control in which response speed of light quantity control in a case where the outside light detection section detects a decrease in quantity of the outside light is made faster than the response speed of the light quantity control in a case where the outside light detection section detects an increase in quantity of the outside light.
