METHOD AND DEVICE FOR ESTIMATING TOUCH PRESSURE USING IMAGE, RECORDING MEDIUM FOR THE SAME, AND MOBILE DEVICE COMPRISING THE SAME

摘要

PURPOSE: An image-based touch strength measurement method, an apparatus thereof, recording medium, and a mobile device are provided to efficiently prevent measurement error according to the external vibrations of an acceleration sensor. CONSTITUTION: An image processing unit(20) detects the blurring degree of an image from a camera unit(10). An operation unit(30) calculates touch strength according to the blurring degree of image frames. The image processing unit quantizes the blurring degree. The operation unit calculates touch strength according to an effective blur value.
