    • An imaging apparatus comprises an optical magnification changing mechanism which optically changes a magnification of an image, and an electronic magnification change mechanism which reduces or expands a magnification with respect to image data by signal processing. The optical magnification changing mechanism is configured so that a magnification is discrete and a focal position changes together with a focal distance. The electronic magnification change mechanism carries out an interpolation process such that the number of pixels is increased with respect to a predetermined region of read image data during an expanding process, and carried out a process for discretely sampling a wide region as compared with a readout region obtained by the sampling provided when no magnification conversion is made, during a reducing process, thereby offsetting a change of the focal position in the optical magnification changing mechanism.
    • 成像装置包括光学变化图像的倍率的光学倍率改变机构和通过信号处理相对于图像数据减小或扩大放大率的电子倍率改变机构。 光学倍率改变机构被配置为使得放大率离散并且焦点位置与焦距一起改变。 电子倍率变化机构执行插值处理,使得在扩展处理期间相对于读取图像数据的预定区域的像素数量增加,并且与读出区域相比进行用于离散采样宽区域的处理 通过在不进行放大转换的情况下提供的采样获得,在减少处理期间,从而抵消光学倍率改变机构中的焦点位置的变化。

    • It is possible to acquire an image of a human figure in which pores or fine wrinkles cannot be displayed in detail even when the image is enlarged by image processing, and acquire an image of a distant view or a distant human figure in which enlarged portions can also be displayed in detail by image processing. The invention provides a camera including an image-acquisition unit for acquiring an image; a magnification detection unit for detecting an imaging magnification; and an image adjusting unit for changing at least one of resolution and contrast of the image acquired by the image-acquisition unit, wherein the image adjusting unit adjusts to a predetermined resolution or contrast that are lower than the resolution or contrast capable of being acquired by the image-acquisition unit when the imaging magnification detected by the magnification detection unit is larger than a predetermined magnification.
