Abstract:
Techniques to adaptively select bracket settings during auto-exposure bracket (AEB) operations are described. In general, AEB settings for a current image may be based on the evaluation of prior bracketed images. For example, the current exposure setting established by an auto-exposure mechanism (EV0) may be compared with a prior EV0 image. If the two are consistent, the prior image's lower and upper f-stop setting images (EV− and EV+) may be used to adaptively change the bracket settings for the current image's EV− and EV+ images. In another implementation, the most recently obtained EV− and EV+ images may be used to adaptively change the bracket settings for the current image—no prior capture being necessary.
