  • Publication number: 20220256119
    Abstract: A medical image assistance system and a medical image assistance method are provided. During a medical process, an image capturing apparatus located at a local location captures a first image and transmits the first image to a control device located at the local location, and the control device transmits the first image captured by the image capturing apparatus to an electronic apparatus located at a remote location. The electronic apparatus performs a marking operation on the first image to generate a second image, and transmits the second image to the control device. The control device transmits the second image to a head-mounted display apparatus located at the local location so that the head-mounted display apparatus simultaneously displays the second image and a real-time local image. The first image and the second image are at least partially the same in content.

    Abstract: A full-zone optical image addressing apparatus, including an addressing device, an image extraction converter, a comparator, an AND gate and a counter. The addressing device is located at the enclosure of the scanner and includes a plurality of geometric patterns. Each of the geometric patterns includes a plurality of rows of pixels. While receiving an exposure signal, the image extraction converter extracts one row of pixels from the addressing device, such that a series of analog signals is obtained and output to the comparator. The comparator then compares the series of analog signals to an analog critical voltage to output a series of analog comparison signals to the AND gate. The AND gate synchronously processes the series of analog comparison signals and a pixel rate clock to output the pixel data corresponding to the extracted row of pixels to the counter.

  • Patent number: 7710612
    Abstract: A method of effacing zipper image, applicable to scan a document by a scanner with a stagger charge-coupled device. The nth (n is a positive integer) pixel value obtained by scan on a scan line at which the zipper image is produced is subtracted by the (n+1)th pixel value obtained by scan on the scan line. The absolute value of the result is then compared to a critical value. If the result is smaller than the critical value, the nth pixel is modified by the method.

  • Patent number: 7515317
    Abstract: A method of compensating a zipper image by a K-value, and a method of calculating the K-value. Whether the nth primitive pixel of the mth line is obtained by primary line scan is determined. If the nth primitive pixel of the mth line is obtained by primary line scan, the nth primitive pixel of the mth line is compensated as the nth primitive pixel of the mth line minus a sum of the (n?1)th primitive pixel of the (m?k)th line and the (n+1 )th primitive pixel of the (m?k)th line multiplied by the K-value. If the nth primitive pixel of the mth line is obtained by secondary line scan, the nth primitive pixel of the mth line is compensated as the nth primitive pixel of the mth line minus a multiplication of the K-value and a sum of the (n?1)th primitive pixel of the (m+k)th line and the (n+1)th primitive pixel of the (m+k)th line.
