Patent ID: 8629913

Claim:
A method comprising: using image signal processing (ISP) logic to receive incoming pixels corresponding to a plurality of image frames captured using a digital image sensor; sending the incoming pixels to an input buffer associated with the digital image sensor; providing a first pixel of a first image frame from the input buffer to a destination unit downstream from the input buffer, the destination unit being associated with the ISP logic; determining if an overflow condition is present in the ISP logic and, if and while the overflow condition is present, stopping the sending of the incoming pixels to the input buffer by dropping the incoming pixels, determining after each dropped incoming pixel whether the overflow condition is still present, and counting each dropped incoming pixel that corresponds to the first image frame while the overflow condition is still present; determining whether the overflow condition is no longer present; and if the overflow condition is no longer present, providing a second pixel of the first image frame to the destination unit and resuming the sending of incoming pixels to the input buffer.
