Video display apparatus

Abstract

In a video display apparatus A, a controller 9 , while displaying video processed by a video processor 4 on a video display 3 , displays LUTs 45 R, 45 G, and 45 B which are tables of correction data for correcting luminance levels of red, green, and blue respectively. The controller 9 re-calculates and rewrites the correction data based on one adjustment point or two or more adjustment points P 1 and P 2 adjusted by the user.

         2 . A display device, comprising:
 a display configured to display an image, the display comprising:
 a first area where content is displayed; and 
 a second area where an adjuster that adjusts the content is displayed, 
   wherein the adjuster comprises a reference line and an adjustment line, and   wherein the content and the adjuster are displayed together.   
     
     
         3 . The display device according to  claim 2 , wherein the reference line is a graph corresponding to a previously stored correction data table. 
     
     
         4 . The display device according to  claim 2 , wherein the reference line is indicated by a broken line. 
     
     
         5 . The display device according to  claim 4 , wherein the adjustment line is indicated by a solid line. 
     
     
         6 . The display device according to  claim 3 , wherein the adjustment line is a graph representing a relationship between:
 input values before correction based on the correction data table; and   output values after correction based on the correction data table.   
     
     
         7 . The display device according to  claim 2 , further comprising a control unit configured to control the display to display the content and the adjuster together. 
     
     
         8 . The display device according to  claim 7 , further comprising:
 an operation unit configured to output an operation signal,   wherein the adjustment line has an adjustment point, of which a setting can be changed, and   wherein the control unit is further configured to changeably control the adjustment point based on the operation signal.   
     
     
         9 . The display device according to  claim 7 , wherein:
 the adjustment line has an adjustment point, of which a setting can be changed; and   the control unit is further configured to control display of a plurality of adjusters corresponding to a plurality of color components in the second area.   
     
     
         10 . The display device according to  claim 9 , wherein the plurality of adjusters comprise red, green, and blue adjusters. 
     
     
         11 . The display device according to  claim 9 , wherein the plurality of adjusters are each a graph in which:
 one of vertical and horizontal axes represents input luminance level; and   another of the vertical and horizontal axes represents output luminance level.   
     
     
         12 . The display device according to  claim 11 , further comprising:
 an operation unit configured to output an operation signal,   wherein the control unit is further configured to set a number of adjustment points on the graph based on the operation signal.   
     
     
         13 . The display device according to  claim 11 , further comprising:
 an operation unit configured to output an operation signal,   wherein the control unit is further configured to adjust output luminance levels at the adjustment points based on the operation signal.   
     
     
         14 . The display device according to  claim 12 , wherein the control unit is further configured to determine an interval between the adjustment points based on the number of adjustment points. 
     
     
         15 . The display device according to  claim 12 , wherein input luminance levels at the adjustment points are fixed. 
     
     
         16 . The display device according to  claim 7 , wherein, upon accepting a cancelling operation, the control unit is further configured to not apply a correction data table based on adjustment operation as a look-up table. 
     
     
         17 . The display device according to  claim 7 , wherein, upon accepting a setting operation, the control unit is further configured to apply a correction data table based on adjustment operation as a look-up table. 
     
     
         18 . The display device according to  claim 7 , wherein, upon accepting a resetting operation, the control unit is further configured to control display, on the display, of a message asking whether or not to reset a correction data table that is currently being applied to a look-up table. 
     
     
         19 . The display device according to  claim 7 , wherein, upon accepting a resetting operation, the control unit is further configured to replace a correction data table that is currently being applied to a look-up table with a previously stored correction data table. 
     
     
         20 . The display device according to  claim 7 , wherein, upon accepting a first operation, the control unit is further configured to control display of an adjustment point setting menu on the display. 
     
     
         21 . The display device according to  claim 7 , wherein, upon accepting a second operation, the control unit is further configured to control display of the adjuster in the second area.
