Apparatus and method for displaying image in mobile terminal

A method for outputting a color image in a mobile terminal with a display unit for outputting the color image, comprising the steps of:

• measuring light quantity and color information of a surrounding environment;
• calculating color information in which a complementary color component of color information output from a color sensor is stressed based on the color information output from the color sensor;
• complementing color information of a source image stored in a memory with the color information in which the complementary color component is stressed;
• and
• outputting the complemented color information to the display unit.

A method for outputting a color image in a mobile terminal with a display unit for outputting the color image, comprising the steps of:

• measuring light quantity and color information of a surrounding environment;
• calculating brightness of the surrounding environment based on the light quantity measured by a color sensor;
• adjusting brightness of an image to be output to the display unit based on the calculated brightness of the surrounding environment;
• and
• outputting the brightness-adjusted image to the display unit.

An apparatus for outputting a color image in a mobile terminal with a display unit for outputting the color image, comprising:

• a color sensor for measuring light quantity and color information of a surrounding environment;
• a memory for storing a lookup table in which color information of a source image to be output to the display unit and color information used for changing the source image are stored;
• and
• a controller for calculating complementary color information of color information output from the color sensor based on the color information output from the color sensor, detecting from the lookup table color information used for outputting the source image to the display unit based on the complementary color information, and outputting the color information detected from the lookup table to the display unit.
