Abstract: An image down-sampling method, for down-sampling a sensing image comprising a plurality of first pixels and a plurality of second pixels which are alternatively arranged, comprising: generating a first output pixel value according to at least one pixel value of at least one of the first pixel in a first down-sampling group; wherein the first down-sampling group comprises an odd number of pixels. By this way, the saw-tooth image issue in prior art may be improved. If the image down-sampling method is applied to a surveillance camera, the accuracy of event detection of the surveillance camera may be increased.

Abstract: There is provided a barcode detection device including an image sensor and a processor. The image sensor captures an image frame of a color barcode. The processor sequentially processes every row of the image frame to find at least one color segment in each row of the image frame, categorizes color segments of a same color in one cluster according to a position relationship and a color similarity of the color segments in the image frame, and averages color parameters of pixels in one cluster to accordingly recognize a color of the pixels in said one cluster.
