Abstract: A method for detecting motion information includes the following steps. First, a pixel array is provided for detecting an image of a measured object located in a first distance range or in a second distance range, and the pixel array includes a plurality of invisible image sensing pixels and a plurality of visible image sensing pixels. Then, image detection is conducted within the first distance range by using the invisible image sensing pixels to output a plurality of invisible images. Next, the image detection is conducted within the second distance range by using the visible image sensing pixels to output a plurality of visible images. Then, the plurality of invisible images and the plurality of visible images are analyzed by using a processing unit, so as to obtain motion information of the measured object. A pixel array for detecting motion information and an image sensor are also provided.

Abstract: A barcode, comprising: a code region, comprising at least two different types of information which represents code information of the code region; and a boundary region, formed as a closed shape surrounding the code region; wherein a decoding direction of the code region is not relative to the boundary region. The present invention also provides a barcode processing system which can process the barcode to generate a control command, and provides a coffee machine using the barcode processing system. The barcode can be easily aligned by a closed boundary region, without using a frame buffer with a large size.

Abstract: An optical tracking device includes a light source, an image sensor and a processing unit. The light source emits light at a lighting frequency. The image sensor outputs an operating image when the light source is being turned on and outputs a background image when the light source is being turned off. The processing unit is configured to obtain background information from the background image, calculate a differential image of the operating image and the background image, obtain object information from the differential image and compare the background information and the object information thereby removing background noise.

Abstract: A method for gesture identification with natural images includes generating a series of variant images by using each two or more successive ones of the natural images, extracting an image feature from each of the variant images, and comparing the varying pattern of the image feature with a gesture definition to identify a gesture. The method is inherently insensitive to indistinctness of images, and supports the motion estimation in axes X, Y, and Z without requiring the detected object to maintain a fixed gesture.
