Patent Images

1. A system for transmitting an image to a machine vision system having a host processor that allocates memory for storage of said image, said system comprising:

  • image acquisition means for acquiring at least a portion of said image in response to a trigger signal, memory means for storing data representative of said image, image transfer means for transferring said image from said image acquisition means to said memory means, said image transfer means including buffer memory means for temporarily storing said at least a portion of said image pending allocation of memory space from said memory means by the host processor, said buffer memory means including a data FIFO register coupled to receive data representative of said image from said image acquisition means and to release data representative of said image to the host processor in response to a release signal, and direct memory address data transfer means for transferring said image data accumulated in said data FIFO register directly memory allocated in a host computer system, whereby said data transfer substantially reduces the number of times said system interrupts the host processor wherein said image acquisition means can operate substantially independently of the allocation of memory by the host processor.
