    • In the picture quality stabilizer for a color laser printer, changes in the gray level characteristic and the color balance caused by changes in temperature and humidity are compensated in order to stabilize the reproduced image. The apparatus includes a temperature and humidity sensor, an upper-bound correction table, a gamma correction table and a mixed color correction table, each optimized with respect to a reference environment, interpolation means for those tables, and a gray level correction means for correcting the gray level with correction coefficients obtained by the interpolation means and the mixed color correction means for compensating any failure of the color balance with the linear transformation. With this configuration, the correction coefficients are so modified as to establish a stable gray level characteristic and color balance, and a stable reproduced image can be obtained.
    • 在用于彩色激光打印机的图像质量稳定器中,补偿由温度和湿度变化引起的灰度特性和颜色平衡的变化,以便稳定再现的图像。 该装置包括温度和湿度传感器,上限校正表,伽马校正表和混合颜色校正表,每个优化相对于参考环境,用于那些表的插值装置和用于校正的灰度级校正装置 具有由插值装置获得的校正系数的灰度级和用于利用线性变换补偿颜色平衡的任何故障的混合色校正装置。 利用这种配置,校正系数被修改以便建立稳定的灰度特性和色彩平衡,并且可以获得稳定的再现图像。

    • Disclosed is an apparatus for measuring a micro area in a specimen in which a reagent necessary for observation and examination of a cell smear specimen or a tissue specimen is dropped to cause a reaction for a measurement and an analysis by way of an image. The apparatus includes: a micro reaction unit that is able to select a specific micro area in the specimen and to subject the specific micro area to a reaction-operation; a unit that measures; records and displays an image of the micro area; and a control unit that controls the measuring, recording, and displaying unit. Reactions can be effected quickly on such specimens as smear cell specimens and tissue slice specimens. The application of the reagent solution can be saved. A comparison between local presence of a gene or anti-body and a cell image can be made quickly and easily.
    • 公开了一种用于测量样本中的微小区域的装置,其中用于观察和检查细胞涂片或组织样本的试剂下降以引起测量反应和通过图像进行分析。 该装置包括:微反应单元,其能够选择样品中的特定微区域并使特定微区域进行反应操作; 衡量单位 记录并显示微区图像; 以及控制单元,其控制测量,记录和显示单元。 反应可以在诸如涂片细胞标本和组织切片标本的样品上快速实现。 可以节省试剂溶液的应用。 基因或抗体的局部存在与细胞图像的比较可以快速且容易地进行。
