Kind Code:
A1
Abstract:
The present invention provides a method for recognizing a single-tone image. The method for recognizing a single-tone image comprises: converting a plurality of rgb optical values corresponding to a plurality of pixels into an HSV color model; forming a statistical histogram according to a plurality of tone values in the HSV color model respectively corresponding to the plurality of pixels, the statistical histogram comprising a plurality of bars, and the plurality of bars respectively corresponding to the quantities of pixels located in different tone value intervals; and determining, according to the quantity of bars, in the statistical histogram, having the quantities of pixels greater than a preset quantity threshold, whether an image is a single-tone image.
