    • An apparatus includes unit acquiring, from an image source, an image represented by pixel values indicating brightness levels, unit setting, as a reference frame, one frame, unit sequentially setting, to be target pixels, each of pixels in one or more frames, unit setting target-image regions including the target pixels, unit searching the reference frame for similar-target-image regions similar to each of the target-image regions in a change pattern of pixel values, unit selecting, from the similar-target-image regions, corresponding points corresponding to each of the target pixels, unit setting sample values concerning brightness at the corresponding points to a pixel value of a target pixel corresponding to the corresponding points, and unit computing pixel values in a high-resolution image corresponding to the reference frame, based on the sample values and the corresponding points, the high-resolution image containing a larger number of pixels than pixels in the reference frame.
    • 一种装置,包括从图像源单元获取由指示亮度级别,单位设置,参考帧,一帧,单位顺序设置为一个或多个帧中的每个像素的目标像素的像素值表示的图像, 单元设置包括目标像素的目标图像区域,在像素值的改变图案中搜索与每个目标图像区域相似的类似目标图像区域的参考帧的单元,从相似目标图像 区域,对应于每个目标像素的对应点,将与对应点对应的目标像素的像素值处的对应点处的亮度的单位设置样本值,以及对应于对应点的高分辨率图像中的单元计算像素值 参考帧,基于样本值和对应点,高分辨率图像包含比参考帧中的像素更大数量的像素。
