    • An image processing apparatus for supporting imaging diagnosis of an eye is provided. A layer boundary of a retina region is detected from a tomographic image. A position where the detected layer boundary intersects with an upper or lower limit position of the image in the depth direction of the tomographic image is determined as a dividing position. The tomographic image is divided at the determined dividing position by a scan line in the depth direction of the tomographic image. Subsequently, whether the detection is a false detection is judged for each divided region. An average density value of the image outside the retina region according to the detected result is calculated for each divided region, and the detection in the divided region is judged to be a false detection if the average density value is equal to or greater than a predetermined threshold.
    • 提供一种用于支持眼睛的成像诊断的图像处理装置。 从断层图像检测视网膜区域的层边界。 被检测的层边界与断层图像的深度方向上的图像的上限或下限位置相交的位置被确定为分割位置。 断层图像在确定的分割位置处被分割成在断层图像的深度方向上的扫描线。 随后,对于每个分割区域判断检测是否为错误检测。 对于每个分割区域计算根据检测结果的视网膜区域外的图像的平均浓度值,并且如果平均浓度值等于或大于预定值,则划分区域中的检测被判断为错误检测 阈。

    • A document reading apparatus includes a document positioning plate configured to position a document, a carriage configured to move a light source along the document positioning plate, a reading unit configured to read an image of a document illuminated by a light source of the carriage, a white reference member provided in the displacement range of the carriage, an input unit configured to input a reading start instruction for a document, and a control unit configured to move the carriage along the document positioning plate in response to a reading start instruction input via the input unit. The control unit moves the carriage to a first position at which the white reference member is provided, cause the reading unit to read the white reference member, moves the carriage to a second position that is an acceleration start position for accelerating toward the reading start position of the document positioning plate, and waits for a reading start instruction input from the input unit.
    • 文件读取装置包括被配置为定位文件的原稿定位板,被构造成沿着原稿定位板移动光源的托架,被配置为读取由托架的光源照射的文件的图像的读取单元, 设置在滑架的位移范围内的白色参考构件,被配置为输入文档的读取开始指令的输入单元和被配置为响应于通过文档定位板输入的读取开始指令而沿着文档定位板移动托架的控制单元 输入单元 控制单元将滑架移动到设置白色基准构件的第一位置,使读取单元读取白色基准构件,将滑架移动到作为加速开始位置的第二位置,以朝向读取开始位置加速 并等待从输入单元输入的读取开始指令。
