IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND STORAGE MEDIUM

摘要

An image processing apparatus corrects a luminance level of an overlap region of projection screens projected by a plurality of image display apparatuses. The image processing apparatus includes: a coordinate conversion unit configured to convert a coordinate value of the overlap region into a coordinate value of an overlap region of not less than a maximum overlap region width; an interpolation calculation unit configured to select two luminance correction data using the converted coordinate value, and to calculate a luminance correction coefficient by interpolating the luminance correction data using the selected luminance correction data and the converted coordinate value; and a correction unit configured to correct the luminance level of the overlap region using the luminance correction coefficient.

1. An image processing apparatus for correcting a luminance level of an overlap region of projection screens projected by a plurality of image display apparatuses, comprising:
a setting unit configured to set an overlap region of the projection screen; a storage unit configured to store luminance correction data required to correct a luminance level of the overlap region; a coordinate conversion unit configured to convert a coordinate value of the overlap region into a coordinate value of an overlap region of not less than a maximum overlap region width, which is configured to be set by said setting unit; an interpolation calculation unit configured to select two luminance correction data using the converted coordinate value from said storage unit, and to calculate a luminance correction coefficient by interpolating the luminance correction data using the selected luminance correction data and the converted coordinate value; and a correction unit configured to correct the luminance level of the overlap region using the luminance correction coefficient.
