An illumination processing method and apparatus relate to the field of video recording technologies, where a liquid crystal panel is disposed between a photosensitive sensor and a lens assembly, and an incident light from the lens assembly reaches the photosensitive sensor after passing through the liquid crystal panel. The method includes determining a highlight region on a first image captured from the photosensitive sensor, and turning down light transmittance of each pixel in an adjustment region on the liquid crystal panel, where the adjustment region corresponds to the highlight region. According to the illumination processing method and apparatus, occurrence of a highlight blooming phenomenon can be avoided as much as possible, thereby avoiding loss of valid image information.

A data access method and apparatus, where the method includes acquiring a data read request that is for a first disk group and carries a read address, determining a first-stripe location range of the first disk group according to the read address, sequentially reading data from first stripes within the first-stripe location range, setting a data reading result for a first stripe whose data is not successfully read to preset padding data, continuing to read data from a next first stripe until data is read from all the first stripes, and returning a data reading result for each first stripe. Thus the method and apparatus may reduce data loss and shortens access interruption time when data is not successfully read.
