A color-processing method includes: selecting a target color gamut to produce an input color signal; calculating a mixture ratio enabling primary colors of the target color gamut to be created by mixing primary colors of a color gamut of the color reproduction apparatus to reproduce the input color signal therewith; producing primary colors reconfigured by mixing the primary colors of the color gamut of the color reproduction apparatus according to the calculated mixture ratio; adjusting an illuminant to match an output signal to a color gamut determined by the reconfigured primary colors; and converting the input color signal to match to the primary colors determined by the reconfigured primary colors. Further a user can arbitrarily set a color gamut in a range that a color reproduction apparatus can reproduce regardless of an input color signal without a quantization errors.

Color display apparatus and method therefor

A method and apparatus for transmitting/receiving data in which a color gamut identifier is included using a synchronization section of an analog image signal are provided. In the method, it is determined whether an analog image signal is a color gamut signal. If the analog signal is a color gamut signal, a color gamut identifier is generated using a synchronization section of the analog image signal, and the analog image signal is transmitted after the color gamut identifier is added to the synchronization section of the analog image signal.

Provided are an apparatus and method for stably correcting handshake that occurs during a camera panning situation. In the method, movement information is accumulated by a predetermined unit for a predetermined period of time. A regression model is matched to the accumulated movement information so as to determine a situation as one of a panning mode and a handshake mode. Switching is performed between the handshake mode and the panning mode according to the size of a matching factor generated by the matched regression model. Handshake is corrected on the basis of a handshake correcting amount determined according to one of the handshake mode and the panning mode.
