摘要:
A color conversion method and apparatus for a multi-primary display (MPD) are provided with analyzing an input image to determine a transformation parameter; interpolating at least two look-up tables for color conversion according to the transformation parameter, in order to calculate a look-up table for the input image; and applying the calculated look-up table to the input image to perform the color conversion. Accordingly, it is possible to provide good color reproduction and efficiently use a color gamut of an MPD having color coordinates that are different from those of primaries of an input image.

A two dimensional/three dimensional (2D/3D) switchable autostereoscopic display apparatus and method. The 2D/3D switchable autostereoscopic display apparatus and method may selectively display a 2D image and 3D image using two displays, control a display operated as backlight from among the two displays when displaying the 2D image, and thereby may increase a contrast. Also, the 2D/3D switchable autostereoscopic display apparatus and method may output a 2D object and a 3D background using two displays.

A method and apparatus for dithering for multi-toning are provided. The apparatus includes a mask-pattern-generating unit that generates a mask pattern on R channel, G channel and B channel by selecting pattern values constituting the mask pattern on the channels based on randomly-determined seed values; a spatial-weight-determining unit that determines the weight for spatial dithering by using the pattern values and K-bit LSB data of the high-tone input image; and an output unit that outputs an M-bit image by applying the weight to M-bit input image data, exempting the K-bit LSB data, in a dithering apparatus for expressing an M+K bit high-tone input image in an M-bit low-tone output device.

An apparatus and method for improving visibility of an image. The apparatus includes: an image input module receiving an image; an illuminance sensing module sensing external illuminance; a visibility compensating module compensating the input image by mapping the input image from a first color gamut to a second color gamut on the basis of the sensed external illuminance; and an image output module outputting the compensated image.
