摘要 |
In an image displaying apparatus, first and second detecting units detect quantities of light propagating through a light path at two different locations. A variation calculating unit calculates the variation in the light quantity in the light path based on the quantities of light detected by each of the first and second detecting units. A controlling unit controls the quantity of light propagated to the screen if the variation in the light quantity exceeds a predetermined value.
