Image display apparatus, picture signal processing method, and program

A picture signal processing method for controlling a panel that includes a plurality of picture elements that change transmittance of light according to picture levels, said picture signal processing method comprising:

• detecting, in one-image portions of said panel, picture levels for each of said plurality of picture elements from picture signals that indicate said picture levels of each picture element;
• and
• adjusting said transmittance of light of said plurality of picture elements such that images produced by said picture signals are brighter when a value that corresponds to brightness that is based on the picture levels of one-image portions that were detected is greater than a predetermined threshold value.

A computer-readable storage medium storing a program for causing a computer that controls a panel that includes a plurality of picture elements that change transmittance of light according to picture levels to execute processes of:

• detecting, in one-image portions, picture levels for each of said plurality of picture elements from picture signals that indicate said picture levels of each picture element;
• and
• adjusting said transmittance of light of said plurality of picture elements such that images produced by said picture signals are brighter when a value that corresponds to brightness that is based on said one-image portions of picture levels that were detected is greater than a predetermined threshold value.
