摘要： Color correction according to the present disclosure performs correction by adding a predetermined correction value to an input value of a component to be corrected, which is one of a plurality of components for representing a color with a predetermined color space, and outputs a corrected value. The color correction includes calculating an unadjusted correction value based on the input value; and adjusting the unadjusted correction value calculated in the calculating the unadjusted correction value so that the corrected value does not decrease with an increase in the input value, and outputting the adjusted value as the predetermined correction value.

摘要： A contour correcting device of the present invention includes a plurality of delay elements which delay an input video signal, a pixel-selection-control-signal generation circuit, a pixel selection circuit which selects outputs of the plurality of delay elements in response to outputs of the pixel-selection-control-signal generation circuit, a high-pass filter operation circuit which weights and adds or subtracts pixel data selected by the pixel selection circuit, and an adder circuit which adds an operation result of the high-pass filter operation circuit to the input video signal.

摘要： In order that such a signal as is conventionally determined to be a standard signal in the unit of one field and determined to be a non-standard signal in the unit of a plurality of fields can be determined to be a non-standard signal, the following are provided: a clock generating circuit for generating a clock of a frequency being a constant multiple of the color carrier frequency; a register for setting the clock count of one field section of a standard signal; a vertical counter for counting the number of clocks generated by the clock generating circuit, and being reset when the clock count reaches the value of the register; and a flip-flop receiving the counter output as the input and using an external vertical synchronizing signal as a load hold pulse. Consequently, the output of the flip-flop represents the inter-field shift of the clock count represented by the external vertical synchronizing signal from the standard signal which shift is accumulated over a plurality of fields, so that even such a signal as is conventionally determined to be a standard signal in the unit of one field and determined to be a non-standard signal in the unit of a plurality of fields can be determined to be a non-standard signal.
