Definitions
- one image is taken as input and one resultant image is produced as output.
- Pixel counter 36 also includes a 2-bit counter for counting the number of scan lines passing through the overlap processor 10. Pixel counter 36 sends a signal to logic controller representative of the number of scan lines counted.
- Control logic 42 is a standard circuit which will generate a signal responsive to the signals received from the pixel counter 36 and detectors 38 and 40.
- the signals generated by control logic 42 are delivered to the FIFO buffers 12, 14 and 16 for reading out the scan lines of pixel data stored therein and to the multiplexer 18 for switching between inputs for reading out a stitched video signal.
- the individual read video streams show when the read operation is performed on each of the three FIFO line buffers 12, 14 and 16 and which scan line of pixels are present on each stream.
- the stitched video stream is wider by an amount equal to the width of kernel 66. This length extension is typically removed as the video is processed by the computational processor 50.
- the trail zone FIFO 16 read is initially delayed by two entire scan line trail edges plus the width of kernel 66 divided by two (W/2) and terminates a width (W) of kernel 66 pixels after the same scan line trail edge. All subsequent trail zone reads are delayed by W pixels from LVAL rising edge and are of length LVAL. 20
- detector 40 sends a signal to logic controller 42 which issues a fourth switching signal to multiplexer 18. Responsive to the fourth switching signal, multiplexer 18 disables the output to output 48 or defaults to a disabled condition.
