A digital camera for having a variable time duration burst capture mode, comprising: an image sensor; an optical system; a data processing system; a frame buffer memory; and a program memory. The program memory stores instructions including: specifying a first frame rate; initiating an image capture sequence; storing a sequence of digital images captured at the first frame rate in the frame buffer memory; determining whether the frame buffer memory has been filled to a predetermined capacity. If the frame buffer memory has been filled to the predetermined capacity, the program memory further includes instructions for specifying a second frame rate, wherein the second frame rate is lower than the first frame rate; designating a set of stored digital images that can be overwritten; and storing a sequence of digital images captured at the second frame rate in the frame buffer memory, overwriting the designated set of stored digital images. |
