UNEVENNESS CORRECTION SYSTEM, UNEVENNESS CORRECTION METHOD, AND DISPLAY DEVICE

摘要

Provided is an unevenness correction system (1) that generates unevenness correction data for correcting display unevenness on a display device. The unevenness correction system includes a signal source (11), an imaging device (12), and a control device (13). The signal source outputs a signal for displaying a reference image in the display region of a display device. The imaging device captures the reference image displayed in the display region on the basis of the signal and generates a captured image. On the basis of the captured image, the control device generates unevenness correction data (D10) that indicates a correction amount for each correction node representing discrete pixel position in the display region. The correction nodes include basic nodes (51) located at lattice points that split the display region into a grid. The control device establishes an additional node (52) that is a correction node different from the basic nodes in accordance with a luminance difference existing locally between the basic nodes in the display region.
