    • PROBLEM TO BE SOLVED: To accurately detect a moving object with arithmetic processing in which median values determined from respective pixel values at the same pixel position of images overlapped are less than an evaluation value for detecting the moving object.SOLUTION: A step of superposing process is executed which groups captured images into groups P with each continuous frame m to process using a superposition method for every image with frames m of the groups p. Based on an evaluation value for detecting space debris determined from pixel values at the same pixel position where the superposed images with the frames m are superposed on each other, candidates for the space debris are extracted for the respective groups. The candidates for the space debris of the respective extracted groups are determined on whether or not the candidates are qualified as final candidates on the basis of coincidence or approximation of movement direction and movement speed. This enables the space debris to be accurately detected with arithmetic processing smaller than the processing for detecting the space debris on the basis of an evaluation value determined from the pixel values at the same pixel position of all superposed images.
    • 要解决的问题:通过算术处理精确地检测运动物体,其中由重叠的图像的相同像素位置处的各个像素值确定的中值小于用于检测移动物体的评估值。解决方案:重叠处理的步骤 被执行,其将捕获的图像分组为具有每个连续帧m的组P,以使用用于具有组p的帧m的每个图像的叠加方法进行处理。 基于用于检测由具有帧m叠加的叠加图像的相同像素位置处的像素值确定的空间碎片的评估值,针对各组提取空间碎片的候选。 基于运动方向和移动速度的一致或近似,确定候选者是否被认定为最终候选者来确定各提取组的空间碎片的候选者。 这使得能够基于从所有叠加图像的相同像素位置处的像素值确定的评估值的算术处理小于用于检测空间碎片的处理来精确地检测空间碎片。

    • PROBLEM TO BE SOLVED: To reduce noise and to generate a highly dynamic range image and the like by synthesizing images where a motion compensation image by highly precise motion estimation is applied.SOLUTION: A moving amount between images is estimated, motion compensation processing where one image is position-adjusted to another image is performed, a motion compensation image is generated, and an image where noise is reduced by synthesis processing of the motion compensation image and the positioned image is generated. A motion compensation image generation section generates the motion compensation image using a selected image selected in accordance with a previously specified image selection standard. An image processor includes a motion estimation appropriateness determination section for determining whether the input image is an appropriate image suitable for motion estimation or not, for example. Only when the input image is the appropriate image, the input image is stored in a frame memory as a reference image applied for motion estimation.
