Patent ID: 7016461

Claim:
An image processing unit for performing x-ray imager control and image processing functions in a dental x-ray apparatus, comprising: a FIFO Registry, a Full Adder and an Image Memory connected by a data bus; a control logic functional unit comprising programmable logic to generate a phase sequence or addressing function for said x-ray imager and control signals to control enabling and data exchange between said FIFO Registry, said Full Adder and said Image Memory through said data bus; a functional converter for performing analogue to digital conversion of a video out signal generrated by said x-ray imager, synchronized with a pixel rate by said control logic; said data bus is a parallel data bus and digital pixel data output from said functional converter is provided to said parallel data bus; said parallel data bus is a data channel through which pixel data is exchanged between said converter, said FIFO registry, said Full Adder and said image Memory; said FIFO Registry comprises a temporary storage device, wherein pixel data are stored, processed and shifted before transfer to said image memory; said Full Adder performs an add ooperation on FIFO data; and a Cassette Speed Simulator (CSS).
