ELECTROOPTICAL APPARATUS, ELECTRONIC DEVICE, AND APPARATUS AND METHOD FOR DETECTING OUTSIDE LIGHT

摘要

An electrooptical apparatus includes a display unit that emits display light, a light emission stopping unit that stops emission of the display light in the display unit, a light receiving unit that receives outside light around the display unit while emission of the display light is stopped, an accumulating unit that accumulates the amount of outside light received by the light receiving unit, and a calculating unit that calculates the light intensity of outside light on the basis of the time taken for the accumulated amount of outside light received to exceed a predetermined threshold.
