APPARATUS AND METHOD FOR INPUT USING IMAGE SENSOR

摘要

An inputting apparatus using an image capturing sensor and a method thereof are provided to enable a user to input data by using a mouse inputting scheme, namely a drag & drop function, even in a portable device. An inputting method using an image capturing sensor comprises the following several steps. If the image capturing sensor senses a movement(ST1), a preprocessor of a calculation unit performs a preprocess(ST2), and a quantization unit performs a quantization process(ST3). A comparison unit finds an image whose pattern difference is minimized(ST4). The orientation selecting unit finds the smallest value among outputted values, namely calculates a movement vector via movement information between one image and its most similar image(ST5).
