Patent ID: 7986332

Claim:
A projector comprising: a projection section that projects an image onto an object on which the image is projected, a viewing environment detection section adopted to detect a viewing environment including ambient light and the object, and to generate environmental information expressing the viewing environment, a correction section adopted to correct input-output characteristic data for projecting the image based on the environmental information, wherein the input-output characteristic data indicates a relationship between grayscale values of an input and grayscale values of an output, the grayscale values varying within a lower grayscale range, a medium grayscale range, and a higher grayscale range; wherein the projection section projects an image for inputting a type of screen; wherein the viewing environment detection section includes a first input section adopted to input information dependent on the type of screen as first environmental information and a second input section adopted to input information about the ambient light as second environmental information, the first environmental information and the second environmental information being part of the environmental information; and wherein the correction section corrects the input-output characteristic data in such a manner as to increase the grayscale values of the output corresponding to at least the lower grayscale range when the viewing environment is brighter than a predetermined brightness.
