摘要： A method and an apparatus for changing the brightness of an image are provided. The method for changing the brightness of an image includes obtaining a level incremental rate, which denotes the degree to which the brightness of three input color components, i.e., first, second and third color components, will be increased according to a determined color gamut, scaling the input color components using the level incremental rate and determining the results of the scaling as incremental values of the input color components, obtaining a fourth color component value using the incremental values, and obtaining output color components, the brightnesses of which are increased from those of the input color components, using the fourth color component value and the incremental values.

摘要： Provided are an image brightness controlling apparatus and method, and an adaptive brightness controlling apparatus and method based on the brightness degree and/or brightness range of an image. The image brightness controlling apparatus includes a brightness increment arithmetic unit for outputting a brightness increment for a pixel, and an individual component brightness increment arithmetic unit for outputting the brightness increments of individual components constituting the pixel in response to the brightness increment for a pixel. The individual component brightness increment arithmetic unit multiplies the brightness increment of the pixel by each of the unit vectors of the components constituting the pixel to obtain the brightness increments of the individual components. The image brightness controlling apparatus further includes an adder for adding the components constituting the pixel to the brightness increments of the components. The image brightness controlling apparatus and the adaptive image brightness controlling apparatus can maintain the sense of color of an image (e.g., the hue or chroma of an image) while increasing the brightness degree and brightness range of an image.
