Abstract:
1. A method for generating a thumbnail image, comprising: discarding data of a portion of lines of an original image of an original document; combining data not discarded to generate the thumbnail image corresponding to the original image; identifying the portion of lines to be discarded based on a y_position value and a y_increment value; selecting pixels in lines not discarded that are within a neighborhood from a current x_position value and an x_size value; combining values of selected pixels to generate a value of a current pixel of the thumbnail image; including one or more pixels in a first neighborhood that are within a boundary corresponding to the current x_position value and a position corresponding to a sum of the current x_position value and the x_size value; generating a next current x_position value for a next pixel of the thumbnail image by: using repeatedly a last pixel when positions corresponding to the sum of a value of the current x_position value and the x_size value exceed a position of a last pixel in a current line of the original image.
