    Abstract: An optical decoding device, comprising: an image sensor, configured to sense first sensing images and second sensing images; a processing circuit, configured to determine a relative movement between the optical decoding device and an object according to the first sensing images; and a decoding device, configured to decode the second sensing images in a first mode to generate a decoding result and does not decode the second sensing images in a second mode. The decoding device switches between the first mode and the second mode according to the relative movement, thus can save power. A barcode, a color code which can be provided on a curved surface and an invisible code are also disclosed. An electrical cigarette lighter using the optical decoding device to provide heat is also disclosed.

    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: 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: 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 barcode, comprising: a code region, comprising at least bright point and a dark point, comprising code information; and a boundary region, formed as a closed shape surrounding the code region. A decoding direction of the code region is not relative to the boundary region. The code information is represented by at least one of: a color sequence, an intensity sequence and a relation between the bright point and the dark point. 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.
