Abstract: Conventionally, a user interface used to change the color of a digital image has a configuration in which three elements, i.e., hue, chroma, and brightness are independent from each other, and the relationship among the three elements are difficult to be recognized, resulting in poor usability. This invention provides a user interface which movably displays a color object that represents an original color on a chromaticity diagram that expresses an arbitrary color system. The user can designate a destination color by moving the color object on the chromaticity diagram. For this reason, the user can easily select and designate a practical color.

Abstract: A digital time base corrector uses a memory with a reduced storage capacity, to reduce the cost. Absolute value data of an amplitude and polarity data of a burst signal in a color video signal are written into a memory every horizontal scan period. A signal in which a sync signal interval, a pedestal level interval, and a burst signal interval in the color video signal are eliminated is written as image data into the memory. The absolute value data, polarity data, and image data are read out from the memory. Burst signal data is reproduced on the basis of the absolute value data and polarity data. By inserting the burst signal data, sync signal data, and pedestal level data into the image data, a color video signal is reproduced.

Abstract: A digital time base corrector which can perfectly eliminate residual errors. A sync clock signal whose phase is synchronized with a time base fluctuation included in a reproduction video signal is formed in accordance with at least one of the horizontal sync signal and the color burst signal which are separated from a reproduction video signal. The sync clock signal is phase-modulated in accordance with a burst error signal indicative of the time base fluctuation of the color burst signal in a period of time other than the generating period of time of at least the color burst signal in the reproduction video signal, thereby obtaining a write clock signal of the image memory.

Abstract: A digital time base corrector reduces the capacity of a memory to approximately a 1 H of image data while maintains the interleave relationship between a luminance signal and a chrominance signal of a video signal. Polarity data indicating the polarity of a burst signal is generated every 1 H, and a latch circuit is provided for holding and outputting the polarity data during a period of reading image data and polarity data from an image data memory and a sub-carrier phase memory, corresponding to the 1 H in which the polarity data was generated. When dropout occurs in a video signal, the image data and the polarity data are inhibited from being written into the image data memory and the sub-carrier phase memory. When discrepancy is detected between read polarity data and polarity data held in the latch circuit, the color phase of the read image data is inverted.
