    • A store surveillance system, a warning device for use in such system, a store surveillance control method, and program-based instruction implementations of such method facilitate the detection of fraudulent activity in a retail store, supermarket, or other type of store. A store management server has a pattern storage unit that stores occurrence patterns of specific events that occur in a store; a POS terminal that executes a product transaction process; a employee surveillance camera that monitors component factors of the occurrence patterns; and a card reader. In some embodiments, when the POS terminal executes a predetermined exception process, the store management server issues a warning conditionally upon whether event occurrence conditions detected by the employee surveillance camera and card reader match a fraudulence pattern stored as an occurrence pattern, or do not match a normal pattern stored as an occurrence pattern

    • A gradation patch image Ip used for determination of tone characteristics of an apparatus is progressively varied in the tone level thereof from the maximum tone level (level 255) to the minimum tone level (level 0). The gradation patch image is either a toner image continuously and consistently varied in the tone level thereof or a toner image having the tone levels varied stepwise at a smaller pitch than a width of a detection region of a patch sensor. In density detection of such a gradation patch image Ip, toner image densities at portions on either sides in the detection region of the patch sensor are canceled each other out by averaging and hence, only a toner image density substantially at the center of the detection region can be obtained.
    • 用于确定装置的色调特性的灰度色块图像Ip在其音调电平中从最大音调电平(电平255)到最小音调电平(电平0)逐渐变化。 灰度补片图像是调色剂图像在其色调级别上连续且一致地变化,或者具有以与贴片传感器的检测区域的宽度相比更小的间距逐渐变化的调色剂图像。 在这样的灰度片图像Ip的浓度检测中,贴片传感器的检测区域中的任一侧的部分的调色剂图像浓度通过平均而相互抵消,因此只有基本上位于检测区域的中心的调色剂图像浓度 可以获得。

    • An improved optical scanning apparatus is adapted to be such that at either end of the scan range, an optical beam deflected by a reflecting surface of a scanner will pass through an anamorphic lens in scanning optics at a position spaced from its optical axis in the sub-scanning direction. The anamorphic lens has such a sectional profile in the sub-scanning direction that the lens thickness at one end of the sub-scanning direction differs from the thickness at the other end. Also, a high speed optical scanning apparatus based on the dual incidence and the oblique incidence, can prevent a positional variation of a scanning line that is due to a shift of each facet of the rotating polygonal mirror, which is caused by an offset of the rotating axis of the rotating polygonal mirror. The scanning apparatus includes a light source, a rotating polygonal mirror with a plural number of reflecting surfaces for reflecting and deflecting an optical beam emitted from the light source, transfer optics for receiving the optical beam that is reflected and deflected by a first reflecting surface of the rotating polygonal mirror and transferring the optical beam to a second reflecting surface of the mirror, and scanning optics for scanning a scanned surface with the optical beam that is reflected and deflected by the second reflecting surface.

    • An optical scanner that has a simple construction and which yet exhibits satisfactory imaging performance under varying temperature conditions. Of the two orthogonal scanning cross sections of scanning optics (i.e., the main and sub-scanning cross sections), the one that involves the greater movement of the image plane due to the temperature-dependent changes in optical characteristics (e.g. the variation in the operating wavelength of a light source, the index variation of a lens material and the thermal expansion of a lens itself) is adapted to be the same as the other cross section that involves the greater movement of the image plane due to the change in the distance from the light source to a collimator lens. If necessary, additional correction is effected in such a way that the scanning cross section that involves the greater overall movement of the image plane after correction for temperature changes is adapted to be different from the cross section that involves the greater amount of optical field curvature.
    • 一种光学扫描仪,具有简单的结构,并且在变化的温度条件下表现出令人满意的成像性能。 在扫描光学器件的两个正交扫描横截面(即主扫描和副扫描截面)中,由于光学特性的温度依赖性变化(例如, 光源的工作波长,透镜材料的折射率变化和透镜本身的热膨胀)适合于与由于距离变化引起的图像平面更大移动的另一横截面相同 从光源到准直透镜。 如果需要,进行附加的校正,使得在校正温度变化之后涉及图像平面的更大整体运动的扫描横截面适于与涉及更大量的光场曲率的横截面不同。
