Abstract
There is provided a signal processing device in which its structure is simplified and a source subjected to a pull-down processing is detected at high precision. The signal processing device includes a comparison portion and a detection portion in which fields constituting a signal source are successively inputted, two fields are compared with each other, and it is judged whether or not there is a motion between the two fields, and a logic block for shifting a state on the basis of a judgement result as to whether or not there is a motion in the detection portion and for controlling judgement characteristics of the detection portion on the basis of the shifted state.
Claims9
A signal processing device comprising:
- motion judgement means in which fields constituting a signal source are successively inputted, two fields are compared with each other, and it is judged whether or not there is a motion between the two fields;
- and
- state shift means for shifting a state on the basis of a judgement result of the motion judgement means and for controlling judgement characteristics of the motion judgement means on the basis of the shifted state.
A signal processing method comprising:
- a motion judgement step in which fields constituting a signal source are successively inputted, two fields are compared with each other, and it is judged by judgement means whether or not there is a motion between the two fields;
- and
- a state shift step of shifting a state on the basis of a judgement result at the motion judgement step and controlling judgement characteristics of the motion judgement means on the basis of the shifted state.
