|Title:||Image display and image displaying method for gradation correction|
|Abstract:||A projector 1 detects a luminance distribution in an effective video period of an inputted video luminance signal, and a coefficient calculating circuit 302 calculates a correction coefficient C.sub.i to correct a gradation (FIG. 6A). Then, surrounding brightness is detected, and the correction coefficient C.sub.i is adjusted based on the surrounding brightness to obtain an adjusted correction coefficient C.sub.i' (FIG. 6B). As shown in FIG. 6C, a luminance can be raised to Q according to a brightness signal even for a pixel of a lowest input luminance by adjusting the correction coefficient. Other correction coefficients in a range of 0 to 255 before adjustment are proportionally distributed to a range of 0 to 255-Q, and added with a correction coefficient Q. A luminance of each pixel which belongs to the effective video period of the video luminance signal is adjusted using the adjusted correction coefficient.|
