Abstract: An optical pen comprising a shaft, a pen tip, a light source and an optical sensor. The shaft extends a predetermined length along an axial direction. The pen tip is arranged at one end of the shaft and situated in the same axial direction. The light source produces light that illuminates an outlying surface near the pen tip to generate a reflected imaging light traveling along a light path. The light path has at least a portion near the pen tip overlapping with said axial direction. The optical sensor is disposed in the light path to receive the imaging light and convert it into electrical signals. In light that the light path that captures imaging light from the optical pen is coaxial with the pen tip, when the optical pen is used for writing, the traveling speed, direction, and distance of images captured by the optical sensor are identical to those of the pen tip.

Abstract: The present invention relates to a method compressing image data, more particularly to a method for compressing image data by using characteristic values. At first, input image data are executed by using a pre-processing process of the present invention. The pre-processing process is to use a mathematical calculation method, a filter, or a database to differentiate outlines of objects and to classify different objects of the image data. Then different colors, which are in the outlines of the different objects, are acquired by using a color classifying method and the different colors are used to be different characteristic values of the image data. At last, the different characteristic values are saved individually in a memory to finish the method for compressing image data by classifying colors.
