Title:
UNEVENNESS DEFECT CORRECTION DEVICE, SYSTEM AND PROGRAM, AND TWO-DIMENSIONAL DISPLAY DEVICE WITH UNEVENNESS DEFECT CORRECTION CIRCUIT
Document Type and Number:
Japanese Patent JP2017009891
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide processing steps that efficiently performs correction and compression between gradations, and spatial correction and compression.SOLUTION: A compression processing step between gradations and a compression processing step on a display plane are executed. Also, as pre-processing of the compression processing step between the gradations, the following processing steps are executed: (1) a processing step of encoding the PC component and the Coeff component calculated by principal component analysis processing concerning a picture element area of n pieces of D×D contain each of the pin marks with respect to the pin marks 1-n (n is the number of pin marks specified on the display) specified on the display when the correction amount of a gradation value in a position (x, y) on the display plane is cv; and/or (2) a processing step of holding the data of the line of the front and rear predetermined number in an uncompressed state from the position of specifying the line unevenness with respect to the line unevenness specified on the display when the correction amount of the gradation values in the position (x, y) on the display plane is cv.SELECTED DRAWING: Figure 1
