ABSTRACT:
An image capture system comprises a portable computer having a software-implemented subsystem and a connection to a sensor responsive still image digital camera including a control module and a FIFO buffer for storing more than one but less than two data image frames. When the image subsystem reaches a point during reading of a frame from the buffer where it is “safe” for the next image data frame captured by the image sensor to be stored in the buffer, the subsystem issues a “continue” signal, causing the next image data frame to be stored in the buffer. The “continue” signal is only issued if the buffer has sufficient capacity for the next frame to be completely stored. The “continue” signal minimizes frame loss, optimizes memory requirement, and sensibly drops frames when the host computer cannot handle image data at the same rate they are generated.
