ELECTRONIC DEVICE METHOD COMPUTER PROGRAM FOR NUMERICALLY CALCULATING AN OCCUPIED LEVEL OF DRAWING DATA TAKING INTO OCCUPIED AND UNOCCUPIED PIXEL

摘要

An embodiment of the present disclosure includes the steps of: receiving, by a drawing data analysis apparatus, drawing data of a user; extracting one or more occupied pixels and one or more non-occupied pixels constituting the drawing data; calculating a first occupancy level of the one or more occupied pixels based on an occupied area of the one or more occupied pixels; For the one or more unoccupied pixels, based on the pen pressure value, the color value, the occupancy time value, and the distance value to the occupied pixel, the weight value of the one or more unoccupied pixels is calculated for each unoccupied pixel and adjacent occupied pixels calculating each; calculating a second occupancy level of the one or more unoccupied pixels in consideration of the weight value of the unoccupied pixel and the occupied area of the unoccupied pixel; and calculating the occupancy level of the drawing data using the first occupancy level and the second occupancy level.
