Video display apparatus and video display method

Abstract

According to an aspect of the invention, a video display apparatus includes: a sensor that measures an external environment to output the external environment; a storing unit that stores a correction value associated with the measured value; a adjusting unit that changes the correction value based on a given operation by a user; and a processor that adjusts a picture quality of a picture to be displayed on a display based on the measured value and the correction value.

1 . A video display apparatus comprising:
 a sensor that measures an external environment to output the external environment;   a storing unit that stores a correction value associated with the measured value;   a adjusting unit that changes the correction value based on a given operation by a user; and   a processor that adjusts a picture quality of a picture to be displayed on a display based on the measured value and the correction value.   
   
   
       2 . The video display apparatus according to  claim 1 , wherein the storing unit stores a plurality of correction values associated with the measured value, and
 wherein the adjusting unit changes the measured value.   
   
   
       3 . The video display apparatus according to  claim 1 , wherein the sensor measures an illuminance as the external environment. 
   
   
       4 . The video display apparatus according to  claim 1  further comprising a display that display a video signal adjusted by the processor. 
   
   
       5 . A video display apparatus comprising:
 a display;   a sensor that measures an external environment to output a measured value corresponding to the external environment;   a storing unit that stores a correction value related with the measured value;   a adjusting unit that changes the correction value based on a predetermined operation by a user; and   a processor that adjusts a picture quality of a picture to be displayed on the display based on the measured value and the correction value.   
   
   
       6 . The video display apparatus according to  claim 5 , wherein the storing portion stores a plurality of correction values associated with the measured value, and
 wherein the adjusting unit changes the correction values respectively.   
   
   
       7 . The video display apparatus according to  claim 5 , wherein the sensor measures an illuminance as the measured value. 
   
   
       8 . The video display apparatus according to  claim 5 , wherein the correction value includes a backlight brightness adjusting value for adjusting a backlight brightness of the display, and
 wherein the processor adjusts the backlight brightness by using the backlight adjusting value.   
   
   
       9 . The video display apparatus according to  claim 5 , wherein the correction value includes an LCD panel set value for adjusting an LCD panel setting of the display, and
 wherein the processor adjusts the LCD panel setting by using the LCD panel set value.   
   
   
       10 . The video display apparatus according to  claim 9 , wherein the LCD panel set value is used for gamma correction of the LCD panel. 
   
   
       11 . A video display method for a video display apparatus storing a correction value associated with an external environment; the method comprising:
