Abstract: A control device and a method for controlling scanning speed of a scanner. The control device includes a decision device and a driving device. The decision device further includes an image buffer, an up-down counter and a comparator. The decision device receives the input image data and utilizes the up-down counter to compute data access volume inside the image buffer. The comparator decides whether to increase or decrease the scanning speed according to the data access volume and also outputs decision data to the driving device.

Abstract: A method for recognizing abnormal image is disclosed. The invention utilizes level comparisons of adjacent image lines to determine if there is any abnormal image amid an image picture and whether the abnormal image belongs to shading or LBB. The method comprises the following steps. First of all, two adjacent image lines having level values Pi and Pinull1 are selected. Then an absolute value of the Pi and the Pinull1 is calculated. Next the absolute value is compared with a value X. When the absolute value is smaller than X, then the image lines are determined as normal. On the contrary, when the absolute value is larger than X, then at least one of the image lines is determined as abnormal. Moreover, another two image lines having level values Pinull1 and Pinull2 separately adjacent the image lines having level values Pi and the Pinull1 are selected. An absolute value of the Pinull1 and the Pinull2 is calculated and the absolute value of the Pinull1 and the Pinull2 is compared to the value X. When the absolute value of the Pinull1 and the Pinull2 is smaller than X, then the image lines having level values Pi and Pinull1 are determined as shading. However, when the absolute value of the Pinull1 and the Pinull2 is larger than X, then the image lines having level values Pi, Pinull1, Pinull1 and Pinull2 are determined as LBB.

Abstract: A method for establishing a long-term profile of blood sugar level aiding self-control of the same is provided. The present method includes periodically obtaining a specimen from a patient, and detecting a response of the specimen. Obtaining a blood sugar value of the patient based on the response, and storing the blood sugar values periodically measured. Establishing a long-term profile of blood sugar level from the measured blood sugar values in a form of chart. Furthermore, when the variation of the long-term profile of blood sugar level exceeds a standard, generating a warning signal informing the patient. When the variation of the long-term profile of blood sugar level does not exceed the standard, generating a safety signal informing the patient.

Abstract: The present invention provides a determination method to obtain the optimum image output quality. The method comprising the standard white plate is scanned prior to the scanning document sheet to obtain a first image data. Then, the first image data is calculated to generate the shading curve, noise level, and brightness data, which corresponding to each sensor device. Next, the shading curve or standard values returned to input into the calibration database. Thereafter, the scanning device scanned and exposed the document sheet to obtain a second imaging data that corresponding to each sensor device and to read out the standard curve (shading curve) from the calibration memory simultaneously. Next, a determination method utilized to determine the difference value between the two pixels at neighboring position, if the difference value is smaller than the standard value, then the two neighboring pixels is to be averaged and outputted the average value; else, the output pixel value is equal to the original position of the pixel value. Finally, the corrected image data is outputted which is corrected by calibration method.
