Merging separated pixel data to obtain deeper depth of field

A method includes obtaining separated pixel image data comprising a first sub-image and a second sub-image. The method further includes, for each respective pixel of the separated pixel image data, determining a corresponding location of a scene feature represented by the respective pixel relative to the depth of field, and identifying an out-of-focus pixel based on the corresponding location. The method additionally includes, for each respective out-of-focus pixel, determining a corresponding pixel value based on the corresponding position, a position of the respective out-of-focus pixel within the separated pixel image data, and at least one of a first value of a corresponding first pixel in the first sub-image or a second value of a corresponding second pixel in the second sub-image. The method further includes generating an enhanced image having an extended depth of field based on the corresponding pixel values. 一种方法包括获得包括第一子图像和第二子图像的分离像素图像数据。该方法还包括：对于分离像素图像数据的每个相应像素，确定由相应像素表示的场景特征相对于景深的对应位置，并且基于对应位置识别离焦像
