Abstract: A low power image sensor in which a reference voltage is automatically adjusted and an integrated circuit integrating the image sensor on one chip are provided to remove a preprocessor having a large chip size and large power consumption to reduce raw costs of an optical pointing image sensor drastically and minimize power consumption. An image sensor unit(100) senses light from a subject and converts and outputs it into an electric signal. A comparing unit(200) receives an electric signal from the image sensor. The comparing unit compares a voltage level of the electric signal with a reference voltage, and then outputs an image signal at 1 bit/pixel. An effective image adjusting unit(300) compares bit value distribution of the image signal outputted from the comparing unit with an effective range to adjust the reference voltage, thereby outputting an effective image.

In response to the operation mode signal, the normal mode or at least one test mode is determined. The input pad and an output pad are used as input and output of the tested circuit block even when being operated in the test mode.

A waveform shaping unit(230) shapes the output of the amplification unit on the basis of a reference threshold voltage to provide a square wave.

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).
