Title:
SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING PROGRAM, AND DIGITAL CAMERA
Document Type and Number:
WIPO Patent Application WO/2013/162023
Kind Code:
A1
Abstract:
In the present invention, a signal processing device is provided with: a first computation unit which calculates a first subtraction value on the basis of signals from calibration pixels among signals from an imaging element having imaging-use pixels and calibration-use pixels; a second computation unit which calculates a second subtraction value on the basis of signals from the calibration-use pixels; a third computation unit which calculates a third subtraction value by adding the first subtraction value and the second subtraction value in a predetermined ratio; a subtraction unit which subtracts the third subtraction value from the signals by the imaging-use pixels that are output via pixels that are shared with the signals from the calibration-use pixels; and a control unit which controls the subtraction unit so as to differentiate the ratios between an occurrence time of a high luminance stripe noise and a non-occurrence time thereof.
