Abstract
This video signal processing apparatus includes a signal processing unit that performs tone control on an input video signal having a linear characteristic and a control unit that blends two tone curve characteristics arbitrarily selected from among a plurality of tone curve characteristics prepared in advance and sets the blended tone curve characteristics for the tone control of the signal processing unit.
Claims9
A video signal processing apparatus, comprising:
- control circuitry configured to blend, based on a value of a single blend ratio input by a user, three tone curve characteristics arbitrarily selected from among a plurality of tone curve characteristics prepared in advance;
- signal processing circuitry configured to perform processing of applying the three tone curve characteristics blended by the control circuitry to an input video signal having a linear characteristic;
- and
- a user interface that receives, from the user, selection of the three tone curve characteristics from among four or more tone curve characteristics prepared in advance, and receives, from the user, a parameter for calculating the value of the single blend ratio.

A video signal processing method, comprising:
- a user interface that receives, from the user, selection of three tone curve characteristics from among four or more tone curve characteristics prepared in advance, and receives, from the user, a parameter for calculating a value of a single blend ratio;
- blending, by control circuitry based on the value of the single blend ratio input by the user, the three tone curve characteristics;
- setting the blended tone curve characteristics to signal processing circuitry that applies the blended tone curve characteristics to an input video signal having a linear characteristic.
An image pickup apparatus, comprising:
- an image pickup unit having an image pickup element;
- control circuitry configured to blend, based on a value of a single blend ratio input by a user, three tone curve characteristics arbitrarily selected from among a plurality of tone curve characteristics prepared in advance;
- signal processing circuitry configured to perform processing of applying the tone curve characteristics blended by the control circuitry to an input video signal having a linear characteristic, the input video signal being generated by the image pickup unit;
- and
- a user interface that receives, from the user, selection of the three tone curve characteristics from among four or more tone curve characteristics prepared in advance, and receives, from the user, a parameter for calculating the value of the single blend ratio.
