Abstract: An image correction method able to avoid error image. According to opposite properties of black and white, only the last few bits of the scanned digital signal are extracted for black correction, while only the first few bits of the scanned digital signal are extracted for white correction. Further, the most significant bit of the digital signal is 1 for white correction. Therefore, the unwanted LBB effect on the scanned image caused by dust or spots on the correction document is avoided. In addition, as only a few bits of the scanned digital signal are extracted, the requirement in memory capacity is reduced.

Abstract: A shading correction is employed for a scanner to correct shading distortion. However, an image corrected with the shading corrective curve has shading noise lines due to the effects of various factors in the producing process of the shading corrective curve. The characteristic of the shading noise is that the each value of any primary color channel, of each pixel in a line is higher or lower than of the adjacent two pixels in other lines, wherein a color channel is one of red, green, or blue channel Hence, the quality of the image is improved by removing the shading noise detected from the characteristic described above.

Abstract: A method and a device for automatic capturing of a static image. The automatic static image-capturing device is a scanner. The method includes the following steps. Any changes on a scanning platform are monitored. If a change in the static image on the scanning platform is detected, the change is gauged for a preset time interval to check for any further change during this time interval. If no further change is detected within this time interval, a preset operation is triggered.

Abstract: A method for determining a response of each probe zone on a test strip is provided. The present invention selects an average pixel value of each section of reference white respectively adjacent to the image of a target line to serve as a reference for determining a color response of the target line. When the color response is not less than a predetermined value, representing the target line has a positive response in response to a specific component of a tested solution tested by the test strip, and the specific component is present in the tested solution. The content of the specific component is proportional to the color response. When the color response is less than a predetermined value, representing the target line has a negative response in response to the specific component of the tested solution, and the specific component is absent in the tested solution.
