Title:
SIGNAL PROCESSING DEVICE AND SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/014799
Kind Code:
A1
Abstract:
The present invention suitably performs pixel interpolation with respect to a histogram image in which a distance histogram is allotted to each pixel position. The signal processing device according to the present feature comprises a histogram generation unit that: receives input of a histogram image in which a distance histogram is allotted to each pixel position, the distance histograms being such that a plurality of distance-measurement results are represented as frequency information for each distance; and generates the distance histogram at a to-be-interpolated position in the histogram image on the basis of the distance histograms at a plurality of pixel positions near the to-be-interpolated position.
