    Abstract: A color bar code comprising a code block is disclosed. The code block comprises: a header region, comprising a specific color; and a code region, comprising at least two code color bars with different color kinds, wherein a color sequence of the code color bars indicates a code. The code color bars form concentric layers surrounding the header region. Such color bar code can comprise more information and the contained therein is more easily to be acquired. A code determining system which can determine the code in the color bar code is also disclosed.

    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.

    Abstract: A distance measuring system includes a light source module, an image capturing device and a processing module. The light source module transmits a light beam having a speckle pattern to a first flat surface and a second flat surface, and an object. The image capturing device captures the image of the speckle pattern shown on the first and second flat surfaces, and captures the image of the speckle pattern shown on a surface of the object to produce first reference image information, second reference image information, and object image information. The processing module calculates a displacement vector of the speckle pattern according to the first and second reference image information. The processing module calculates the relative distance between the object and the first flat surface or the second flat surface according to the position of the speckle pattern on the object image information and the displacement vector.

    Abstract: A handwriting system includes a first light source module, a second light source module, an image sensing device and a processing circuit. The first light source module is configured to provide a first light to illuminate an object on a plane. The second light source module is configured to provide a second light to illuminate the object on the plane, wherein the second light source module is disposed under the first light source module. The image sensing device is disposed above the plane and configured to capture an image of the object reflecting the first light only or an image of the object reflecting the first and the second lights both. The processing circuit is electrically connected to the image sensing device and configured to receive the image captured by the image sensing device and generate control information according to light-spot information in the captured image.
