Abstract: The purpose of the present invention is to carry out, simply and reliably, distortion correction and uneven brightness correction, and includes a memory for blending data; a memory for geometric correction data; an image correcting unit; and a CPU which, upon receiving two-dimensional correction data representing the contents of geometric correction data for performing distortion correction and blending data for performing brightness correction, creates the blending data and the geometric correction data based on the two-dimensional correction data, stores the data into the memory for blending data and into the memory for geometric correction data, refers, as regards the input image signal, to the stored contents in the memory for blending data and the memory for geometric correction data and causes the image correcting unit to perform distortion correction and uneven brightness correction in accordance with the stored contents.

Abstract: A video display system comprising a plurality of video display apparatuses 11 to 13 for displaying video signals Sv being supplied as video. A specific video display apparatus 11 out of a plurality of the video display apparatuses 11 to 13 discriminates video characteristics Pv1 to Pv5 of the video signal Sv to output identification signals IDa to IDd that correspond to the discriminated video characteristics (Pa1 to Pa5) to (Pd1 to Pd5) and simultaneously displays the video signal Sv according to the display characteristic characteristics (Qa1 to Qa3) to (Qc1 to Qc3) stored in correspondence to the identification signals IDa to IDd. The other video display apparatuses 12 and 13 than the specific video display apparatus 11 display the video signals Sv according to the display characteristic characteristics (Qa1 to Qa3) to (Qc1 to Qc3) stored in correspondence to the identification signals IDa to IDd.
