ABSTRACT:
A projection type image display apparatus includes an electroluminescence element which has a plurality of pixels that can each emit modulated light, a projection optical system which projects the light emitted from each of the pixels in the electroluminescence element onto an object to display an image, and a sensor which detects brightness of ambient light that illuminates the object. A controller controls brightness of the light emitted from the electroluminescence element based on the brightness of the ambient light.
