Methods for image content detection check (15) color values of pixels via color conditions and check (18) pixels via edge conditions and check (22) functions of numbers of edge conditioned pixels and numbers of color conditioned pixels via ratio conditions and generate (23), in response to ratio condition detection results, block content detection signals. These methods perform well for green content (greeneries like grass, leaves of trees, bushes) and blue content (water like river water, sea water) and are used for content based classifications and automatic selections of images. The methods may be repeated (12) for different blocks of an image, and may then check (32), for a block, neighboring blocks and may check (33-1) functions of numbers of neighboring blocks via block neighbor conditions and may check (33-2) functions of numbers of edge conditioned pixels and numbers of color conditioned pixels via further ratio conditions and may generate (34), in response to block neighbor condition detection results and further ratio condition detection results, image content detection signals. |
