ABSTRACT:
An image projecting apparatus projects an image formed on a display device in accordance with input image data, onto a projection surface with illumination light emitted from a light source, to enable an observer to observe the image. The image projecting apparatus comprises a distribution area recognizing section configured to recognize an area in which the input image data is distributed in a color space, and a projection condition controlling section configured to convert the input image data to increase brightness of the image to be projected onto the projection surface without changing a color balance of the image, based on the area recognized by the distribution area recognizing section, and send image data obtained by conversion of the input image data to the display device, and also control brightness of illumination light emitted from the light source in connection with the conversion of the input image data.
