Abstract: An inputting apparatus using an image capturing sensor and a method thereof are provided to optimize the image capturing sensor with the minimum number of pixels, to convert data per one pixel into one bit data, and to calculate a movement vector with minimum data. An inputting apparatus includes a sensor unit(100) and a calculation unit(200). The sensor unit includes an image capturing sensor(110) which senses a subject(150) and outputs sensed image data. The calculation unit receives the image data from the sensor unit, data per each pixel of the image data into one bit data, compares image data at one time and that after a certain time has passed, and calculates a movement vector. The sensor unit includes a light source(120) for emitting light to the subject and a lens(130) which is a light collecting tool for transmitting an approaching image to the image capturing sensor by the light emitted by the light source. The calculation unit includes a quantization unit(220), a temporary storage unit(230), a comparison unit(240), an orientation unit(250) and a core controller(270). The quantization unit converts data per each pixel of the image data inputted from the sensor unit into one bit data. The temporary storage unit temporarily stores the image data processed by the quantization unit. The comparison unit compares the image data processed by the quantization unit with that temporarily stored at the temporary storage unit. The orientation unit calculates the movement vector from a value outputted by the comparison unit. The core controller controls operations of the calculation unit.

Abstract: 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).
