The invention discloses a region identification method and device, and belongs to the field of image processing. The region identification method comprises that binaryzation is carried out on a text region to obtain a binary text region which comprises multiple characters in the same row; a histogram of the binary text region is calculated according to the vertical direction, and the histogram comprises accumulated values of horizontal coordinates and foreground color pixel points of pixel points in each column; and according to distribution information of the accumulated values in the histogram, a character region of characters in the text region is identified. Thus, the problem that positioning of a text region is low in accuracy in the prior art is solved, and the character region can be accurately positioned according to distribution information of the accumulated values of the foreground color pixel points in the histogram.
