    • A photographic apparatus comprises an imaging sensor, an image-processing unit, and a display unit. The imaging sensor obtains image data. The image-processing unit performs an image-processing operation on the image data. The display unit displays an image-processing setting picture having a setting-status indication area that shows a setting status of the image-processing operation, and having a color status indication area that displays a diagrammatic representation of a color status in the image-processing operation corresponding to the setting status. The setting-status indication area shows hue in the image-processing operation, as the setting status. The color status indication area has a figure that shows saturations of a plurality of color components in the image-processing operation in order to display the diagrammatic representation of the color status. The figure is rotated according to said hue. A shape of the figure and a size of the figure change in accordance with the saturations.
    • 摄影装置包括成像传感器,图像处理单元和显示单元。 成像传感器获取图像数据。 图像处理单元对图像数据执行图像处理操作。 显示单元显示具有设置状态指示区域的图像处理设置图像,该设置状态指示区域显示图像处理操作的设置状态,并且具有在图像处理中显示颜色状态的图示表示的颜色状态指示区域 操作对应于设置状态。 设置状态指示区域在图像处理操作中显示色调作为设置状态。 颜色状态指示区域具有在图像处理操作中显示多个颜色分量的饱和度的图,以便显示颜色状态的图示。 该图根据所述色调旋转。 图形的形状和图形的大小根据饱和度而变化。

    • A focusing unit (11) is constituted of a prism base (11a), deflection prisms (11b and 11c), and a slit chart (11e) having a slit opening (11d), and the deflection prisms (11b and 11c) are arranged so that deflecting directions may become reverse. The slit opening (11d) is made equally to spread across the deflection prisms (11b and 11c) approximately and is impermeable except the slit opening (11d), and light incident on the deflection prisms (11b and 11c) passes only this slit opening (11d). In addition, the light which is emitted by a focus index illumination light source illuminates the slit opening (11d) through the deflection prisms (11b and 11c). As to an image of the illuminated slit opening (11d), two slit images are formed on a fundus of eye by actions of the deflection prisms 11b and 11c. Focus adjustment is made by aligning these slit images (S1 and S2) in a straight line.

    • To provide a technique preferable for ophthalmic image taking having an image taking optical system for imaging an image on an image sensing element at different imaging magnifications. The following are included: an image sensing element for converting the eye-to-be-examined fundus image into digital image data; an image taking optical system for imaging the eye-to-be-examined fundus image on the image sensing element at different image magnifications; fungus illumination means for illuminating fungus at a light intensity interlocking with the imaging magnifications; and region selection means for selecting a specific region including a fundus image from the image data in accordance with the imaging magnifications. Moreover, it is characterized to lower the light intensity of the fundus illumination means by interlocking with reduction of the imaging magnifications and contract the specific region by interlocking with reduction of the imaging magnifications.
