Document Type and Number:
WIPO Patent Application WO/2010/023966
Kind Code:
A1
Abstract:
Provided is an image quality adjusting device (12) which performs image quality adjustment to image information displayed on a screen of a display terminal (11). The image quality adjusting device has an analyzing means (22), which acquires chromaticity data, profile data and histogram data from the image information obtained by photographing the screen of the display terminal (11) by an imaging means (21) and analyzes image quality characteristics. The image quality adjusting device also has an image quality adjusting means (23), which generates a look-up table (LUT) for adjusting the image qualities of the display terminal (11) corresponding to previously set image quality adjustment contents, based on image quality evaluation data, which is obtained from the analyzing means (22) on the display terminal (11), and then adjusts image qualities of the display terminal (11) by updating the image quality information previously set in the display terminal (11), by using the generated look-up table.
