    • In the exposure control circuit of an image input device according to the present invention, the rays of light from the subject pass through a diaphragm adjusting the amount of light and undergoes photoelectric conversion at a CCD imaging element. The image signal read from the CCD imaging element is accumulated more than once at an accumulating circuit. The luminance of the subject is detected at a luminance detector. Based on the detected luminance, a condition setting circuit sets the amount of incident light, exposure time, and the number of additions to suitable values. With those suitable settings, the amount of light through the diaphragm, the exposure time of the CCD imaging element, and the number of accumulations by the accumulating circuit are controlled so as to enable the subject to be photographed under the best condition.

    • Disclosed herein is an image processing apparatus, in which an object image focused by a lens is split into a plurality of images by means of a light splitting section. These images are converted into image data items by a plurality of imaging devices which are arranged with their imaging area overlapping in part. The image data items are stored temporarily in an image storing section. A displacement detecting section detects displacement coefficients (rotation angle R and parallel displacement S) from the image signals representing the mutual overlap region of two images which are to be combined and which are represented by two image data items read from the image storing section. The position of any specified pixel of the image displayed is identified by the pixel signal generated by the corresponding pixel of any imaging device. An interpolation section performs interpolation on the pixel values of the imaging device, thereby correcting the values of the other pixels of the image displayed and ultimately generating interpolated image signals. The interpolated image signals are combined with the image signals produced by the imaging device, whereby a display section displays a high-resolution image.
    • 这里公开了一种图像处理装置,其中由透镜聚焦的对象图像通过分光部分被分割成多个图像。 这些图像通过多个成像装置被转换成图像数据项,这些成像装置被布置成它们的成像区域部分重叠。 图像数据项被临时存储在图像存储部中。 位移检测部分从表示要组合的两个图像的相互重叠区域的图像信号中检测位移系数(旋转角度R和平行位移S),并且由从图像存储部分读取的两个图像数据项表示。 所显示的图像的任何指定像素的位置由任何成像装置的相应像素生成的像素信号来识别。 内插部分对成像装置的像素值执行内插,从而校正显示的图像的其他像素的值,并最终产生内插图像信号。 内插图像信号与由成像装置产生的图像信号组合,由此显示部分显示高分辨率图像。
