Title:
SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, IMAGING DEVICE, ELECTRONIC DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2016/052250
Kind Code:
A1
Abstract:
This invention relates to a signal processing device which, by adding together continuously captured images, reduces noise and false color and improves resolution, and which enables the reduction of artifacts in time base processing; the invention further relates to a signal processing method, an imaging device, an electronic device, and a program. A high pass filter is applied to the pixels of an input image to calculate the degree of aliasing. For an input image and a past image which was previously an input image, interpolated images of three types, R, G and B, are generated by demosaicing, respectively, the R, G and B pixels in a Bayer array, and from the differences between pixels in the input image and the past image, a moving object degree of each of the three types is calculated. The three moving object degrees are outputted weighted with the degree of aliasing. The input image and the past image are synthesized by weighted addition corresponding to the moving object degrees. This invention can be applied to imaging devices.
