Interlace/non-interlace data converter

Claim 2

A data converter receiving video interlaced scan line data input and connected to a memory comprising: means for digitizing the analog input data to digital form; means for converting interlaced formatted data in separate odd and even numbered scan line fields to non-interlaced, sequential locations in the memory alternating odd and even numbered scan lines of the input video field data; and means for generating a series of addresses for storing the interlaced formatted data in non-interlaced format in the memory.

Claim 3

The data converter of claim 1 further including: a central processing unit for inputting initial information controlling the storage of input data in selected locations within the memory.

Claim 4

A data converter receiving digitized interlaced sequential data containing a pre-determined number of pixel elements per scan line in alternating odd/even fields of data per one frame of the camera from a video source and connected to a memory for storing such data, the data converter comprising: control means for controlling the flow of data between the video source and the memory; first means for storing the number of pixel elements per scan line; second means for storing a memory address offset value; third means for storing the number of scan lines per field; and fourth means for storing the even and odd field memory starting addresses; and wherein the values in the first, second, third and fourth storing means are input to the first, second, third and fourth storing means from the control means.

Claim 5

A data converter receiving digitized interlaced sequential data containing a pre-determined number of pixel elements per scan line in alternating odd/even fields of data per one frame of the camera from a video source and connected to a memory for storing such data, the data converter comprising: control means for controlling the flow of data between the video source and the memory; first means for storing the number of pixel elements per scan line; second means for storing a memory address offset value; third means for storing the number of scan lines per field; and fourth means for storing the even and odd field memory starting addresses; and wherein the values in the first, second, third and fourth storing means are input to the first, second, third and fourth storing means from the control means.

Claim 6

The data converter of claim 3 further including: memory address generating means for generating a series of sequential memory addresses; and adder means, for adding the current value in the second storing means and the current value in the memory address generating means to generate the next memory address.

Claim 7

The data converter of claim 3 further including: means for counting the number of pixel elements received from the video source in each scan line of the video source; and the counting means generating an output when the number of pixel elements received equals the pre-set value in the first storing means.

Claim 8

The data converter of claim 5 further including: means receiving as inputs the outputs from the fourth storage means and the adder means for switching the input to the memory address counter between the fourth storing means and the adder means.
