    • An image inspection apparatus includes: a light source configured to emit white light onto a test image formed on a paper sheet; an optical lens system configured to receive light reflected by the paper sheet, the reflected light being of the white light emitted from the light source; a separating unit configured to separate light having passed through the optical lens system; a reading unit configured to receive the separated light at the different wavelengths, and optically read the test image of the light; and a control unit configured to calculate edge blurs at a rising edge and a falling edge of each set of image data of the light obtained by the reading unit reading the test image, calculate widths of the test image, and determine the width calculated from the set of image data having the smallest edge blur to be the width of the test image.
    • 图像检查装置包括:被配置为将白光发射到形成在纸张上的测试图像上的光源; 光学透镜系统,被配置为接收由所述纸张反射的光,所述反射光是从所述光源发射的白光; 分离单元,被配置为分离通过所述光学透镜系统的光; 读取单元,被配置为接收不同波长的分离的光,并且光学地读取所述光的测试图像; 以及控制单元,被配置为计算由读取单元读取测试图像获得的每组图像数据的上升沿和下降沿的边缘模糊,计算测试图像的宽度,并且确定从 具有最小边缘模糊的图像数据集合成为测试图像的宽度。
