Abstract
A method and apparatus is provided for displaying an enlarged image on a liquid crystal display apparatus capable of displaying colors, and in particular, a liquid crystal display method and apparatus that can enlarge an image at an arbitrary ratio and display the outline of the enlarged image smoothly. On a display panel of a color liquid crystal display apparatus in which display dots each comprising an array of three subpixels displaying red (R), green (G), and blue (B) are arranged in a matrix, three pieces of raw-direction original display brightness data to be displayed in three subpixels are extended and subjected to predetermined weights of brightness to form enlarged display brightness data. This data is sequentially output to the subpixels to extend the original image in the raw direction of the display panel before display.
