Abstract
A frame grabber comprising image signal decoders to convert the analog image signal to digital image data, a multiplexer to select the image data stream sent from the image signal decoders, frame memories and a memory controller to control the digital image data in a unit of frame data to be transferred to an external main image processor unit further has a pulse generator, a pulse counter, a bus controller for transferring the frame data and a time stamping code generator to consolidate the same time base between the in-frame image data and other data used for robot controlling.
Claims4
A frame grabber which has a function to output digital image data sourced from analog image signals taken by video cameras to a main image processor unit and a function to make same time base to consolidate said image data with other data to be used for a controller unit under association with said digital image data comprising,
- a pulse generator to generate pulses in synchronous to image synchronous pulses to be output to said video cameras;
- a pulse counter to count said pulses generated by said pulse generator;
- an image data transfer means that has a function to transfer said digital image data in synchronous to sending count numbers obtained as a result of counting said pulses to said controller unit;
- and
- a synchronous signal transmitter to send said count number to said controller unit.
