Abstract: A non-contact human input method is to capture an image in front of a non-contact human input interface of the non-contact human input system, then extract a figure from the image, and then determine whether a user corresponding to the figure is at an input state according to a posture of the figure. The method is to ignore actions of the user when the user is not at the input state. The method is to receive a voice input or a posture input from the user when the user is at the input state. A non-contact human input system includes a displaying device, at least one camera, and a processor electrically connected to the displaying device and the at least one camera. The at least one camera is used to capture an image of a user. The processor implements the above non-contact human input method.

Abstract: An imaging system includes an image sensing unit and a processing unit. The image sensing unit captures a plurality of images of an object, wherein each of the images includes a plurality of pixels. The processing unit obtains a plurality of sets of image data according to the images, wherein each set of image data includes a plurality of characteristic values. The processing unit calculates a plurality of difference parameters of the characteristic values of every two sets of image data. The processing unit accumulates the difference parameters within a predetermined time period to obtain a plurality of accumulated difference parameters corresponding to the pixels. The processing unit determines a plurality of weighting values corresponding to the pixels according to the accumulated difference parameters. The processing unit performs an image processing process according to the sets of image data and the weighting values.

Abstract: An imaging device includes a projection unit, an image sensing unit and a processing unit. The projection unit is controlled by a projection parameter to project a light onto an object, wherein the light forms two color blocks on the object. The image sensing unit is controlled by an image capturing parameter to capture an image of the object, wherein the image includes the two color blocks. The processing unit analyzes the image to calculate a contrast ratio of the two color blocks. The processing unit compares the contrast ratio with a predetermined threshold. When the contrast ratio is larger or smaller than the predetermined threshold, the processing unit selectively adjusts at least one of the projection parameter and the image capturing parameter. The processing unit controls the projection unit to project the light onto the object and controls the image sensing unit to capture the image of the object.

Abstract: A barcode decoding method includes steps of analyzing a relative relationship between at least two characteristic points of a gray level distribution of a target scanning line of a target barcode to obtain at least one reference characteristic parameter; when determining a current distance between a barcode reader and the target barcode being a relatively long distance, dividing the gray level distribution into at least one bar area and at least one space area; setting a gray level region and locating at least one peak point and/or at least one valley point located within the gray level region from the gray level distribution; when the peak point is located within the bar area, interpolating a space corresponding to the peak point into the bar area; and when the valley point is located within the space area, interpolating a bar corresponding to the valley point into the space area.
