Abstract
A method and apparatus for draining video data from a planarized video buffer in a video camera. The method includes the steps of reading a first sequence of video data from a first plane of the planarized image buffer starting at a buffer address indicated by a first pointer, and then reading a second sequence of video data from a second plane of the planarized image buffer starting at a buffer address indicated by a second read pointer. The apparatus includes an address generation unit and a sequence counter. The address generation unit includes a number of read pointers each configured to indicate a memory location within a different data plane of a video buffer. The address unit is configured to address a sequence of memory locations in a video buffer starting at a location indicated by an active one of the read pointers. The sequence counter is configured to detect when a final memory location of the sequence of memory locations has been addressed by the address generation unit and, in response, to select a different one of the read pointers to be the active read pointer.
