The method selects the areas that include the figures of the design patent, and displays the selected areas on a display device. ## Claims ### Claim 1 A method being performed by a processor of a computing device, comprising: (a) reading a figure section of a design patent document comprising one or more figures; (b) converting each page of the figure section into a black-and-white image; (c) creating a first histogram based on information of black pixels and white pixels in the black-and-white image; (d) dividing the black-and-white image into a multiplicity of blocks which contain words or figures, according to the information of the white pixels in the first histogram; (e) selecting the blocks which have a height value greater than a predetermined height value; (f) creating a second histogram based on information of the black pixels and the white pixels in each selected block; (g) dividing the selected block into a multiplicity of areas which contain words or figures, according to the information of the white pixels in the second histogram; (h) selecting the areas which have a width value greater than a predetermined width value; and (i) displaying the selected areas on a display device. ### Claim 2 (depends on 1) The method as claimed in claim 1, between the step (a) and the step (b) further comprising: providing the same orientation to all of the figures in the figure section. ### Claim 3 (depends on 1) The method as claimed in claim 1, wherein in the first histogram, the X-axis or horizontal axis represents the series of numbered rows from the bottom to the top of the black-and-white image, and the Y-axis or vertical axis represents the quantity of the black pixels in each row of the black-and-white image. ### Claim 4 (depends on 1) The method as claimed in claim 1, wherein in the second histogram, the X-axis or horizontal axis represents the series of numbered lines from the left to the right of the selected block, and the Y-axis or vertical axis represents the quantity of the black pixels in each line of the selected block. ### Claim 5 A non-transitory storage medium storing a set of instructions, the set of instructions capable of being executed by a processor of a computing device to perform a method for isolating and cutting out figures in a design patent document, the method comprising: (a) reading a figure section of a design patent document comprising one or more figures; (b) converting each page of the figure section into a black-and-white image; (c) creating a first histogram based on information of black pixels and white pixels in the black-and-white image; (d) dividing the black-and-white image into a multiplicity of blocks which contain words or figures, according to the information of the white pixels in the first histogram; (e) selecting the blocks which have a height value greater than a predetermined height value; (f) creating a second histogram based on information of the black pixels and the white pixels in each selected block; (g) dividing the selected block into a multiplicity of areas which contain words or figures according to the information of the white pixels in the second histogram; (h) selecting the areas which have a width value greater than a predetermined width value; and (i) displaying the selected areas on a display device. ### Claim 6 (depends on 5) The non-transitory storage medium as claimed in claim 5, wherein between the step (a) and the step (b), the method further comprising: providing the same orientation to all of the figures in the figure section. ### Claim 7 (depends on 5) The non-transitory storage medium as claimed in claim 5, wherein in the first histogram, the X-axis or horizontal axis represents the series of numbered rows from the bottom to the top of the black-and-white image, and the Y-axis or vertical axis represents the quantity of the black pixels in each row of the black-and-white image. ### Claim 8 (depends on 5) The non-transitory storage medium as claimed in claim 5, wherein in the second histogram, the X-axis or horizontal axis represents the series of numbered lines from the left to the right of the selected block, and the Y-axis or vertical axis represents the quantity of the black pixels in each line of the selected block. ### Claim 9 A computing device, the computing device being connected to a display device, the computing device comprising: a storage unit; at least one processor; and one or more programs stored in the storage unit, executable by the at least one processor, the one or more programs comprising: a reading module operable to read a figure section of a design patent document comprising one or more figures; a conversion module operable to convert each page of the figure section into a black-and-white image; a creation module operable to create a first histogram based on information of black pixels and white pixels in the black-and-white image; a dividing module operable to divide the black-and-white image into a multiplicity of blocks which contain words or figures, according to the information of the white pixels in the first histogram; a selection module operable to select the blocks which have a height value greater than a predetermined height value; the creation module further operable to create a second histogram based on information of the black pixels and the white pixels in each selected block; the dividing module further operable to divide the selected block into a multiplicity of areas which contain words or figures, according to the information of the white pixels in the second histogram; the selection module further operable to select the areas which have a width value greater than a predetermined width value and a display module operable to display the selected areas on the display device. ### Claim 10 (depends on 9) The computing device as claimed in claim 9, wherein the one or more programs further comprising: a orientation module operable to provide the same orientation to all of the figures in the figure section. ### Claim 11 (depends on 9) The computing device as claimed in claim 9, wherein in the first histogram, the X-axis or horizontal axis represents the series of numbered rows from the bottom to the top of the black-and-white image, and the Y-axis or vertical axis represents the quantity of the black pixels in each row of the black-and-white image. ### Claim 12 (depends on 9) The computing device as claimed in claim 9, wherein in the second histogram, the X-axis or horizontal axis represents the series of numbered lines from the left to the right of the selected block, and the Y-axis or vertical axis represents the quantity of the black pixels in each line of the selected block.
