IMAGE SENSORS AND IMAGE RECONSTRUCTION METHODS FOR CAPTURING HIGH DYNAMIC RANGE IMAGES

摘要

High dynamic range image sensors and image reconstruction methods for capturing high dynamic range images. An image sensor that captures high dynamic range images may include an array of pixels having two sets of pixels, each of which is used to capture an image of a scene. The two sets of pixels may be interleaved together. As an example, the first and second sets of pixels may be formed in odd-row pairs and even-row pairs of the array, respectively. The first set of pixels may use a longer exposure time than the second set of pixels. The exposures of the two sets of pixels may at least partially overlap in time. Image processing circuitry in the image sensors or an associated electronic device may de-interlace the two images and may combine the de-interlaced images to form a high dynamic range image.
