Title:
SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING PROGRAM, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/162124
Kind Code:
A1
Abstract:
A signal processing device is provided with a target signal extraction unit (31) which extracts a plurality of target signals which are targets for denoising, from video signals; a signal extraction unit (32) which, with respect to each target signal, extracts a signal which is in the same frame as the target signal and is distant from the target signal by a predetermined pixel interval; a voltage value differential calculation unit (33) which, with respect to each target signal, calculates a voltage value differential on the basis of the target signal and the distant signal; and a noise amount calculation unit (34) which calculates an occurrence rate with respect of each size of the voltage value differential, and calculates a voltage value differential having the maximum occurrence rate or having the occurrence rate exceeding a predetermined threshold value, as a target noise amount.
