摘要： Complicated adjustment, such as adjusting hue and saturation by varying value for each hue in which hue correction and saturation correction are performed on only an input having a specific value of a specific color component, is performed. In a color space including hue Hi, saturation Si, and value Vi, calculating a hue correction value HVh and a saturation correction value HVs by using the hue Hi and the value Vi as parameters allows the hue correction and the saturation correction to be performed based on the value and completely independently for hue axes of the hue. The correction value calculating circuit scale has no influence on the complexity of the correction. It is possible to calculate the correction values by a certain circuit scale no matter how complicated the correction is.

摘要： An extraction cycle detection unit detects an extraction cycle of VBI data based on a CRI amplitude of a CVBS signal and a pedestal level detection unit detects a pedestal level value of the CVBS signal. A MAX detection unit detects a maximum value of the CRI amplitude. The maximum value of the CRI amplitude and the pedestal level value are supplied to an operation unit to execute an operation to obtain an average value of them, which is input to a data slice unit as a slice level. The data slice unit extracts the VBI data based on the slice level and the extraction cycle from the extraction cycle detection unit. Even if the CRI waveform of the CVBS signal becomes irregular, the slice level is suitably determined and the VBI data is properly extracted.
