Abstract

A method for increasing dynamic range of a time-delay integration (TDI) image includes assigning a value N to a line-number setting and generating each line of the TDI image by (i) selecting N lines from N corresponding images of an image sequence, and (ii) integrating the N lines. The brightness of the TDI image is evaluated, after which the line-number setting is updated to a new value. In another method, the value of a TDI pixel is initialized to the value of a corresponding pixel in a first image of the image sequence. While the TDI pixel value is less than a ceiling, a contribution is added to the TDI pixel value, the contribution being based on the value of an additional corresponding pixel in an additional image of the image sequence. After adding, the resulting TDI pixel value may be scaled based on the number of contributions.
