Abstract
Abstract An image processor comprises a CPU, a ROM for storing programs and data, a main storage memory for storing image data, parameters for image processing and the like, an image memory for storing image data which are to be displayed on a monitoring device, a DA converter for outputting a signal to the external monitoring device or video printer, a DMA controller, a clock signal generator for driving an imager device such as a CCD sensor, an AD converter for converting an image signal SG from the imager device into a digital signal, an input/output circuit for generating a busy signal to an external X-ray controller and receiving an exposure signal from the X-ray controller, etc.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
189 words
A dental X-ray imaging apparatus comprising: an X-ray irradiator for irradiating X-rays to an intraoral region of a subject, said X-ray irradiator being provided outside the oral cavity of a subject, the X-ray irradiator including an X-ray generator, an X-ray tube for generating X-rays, a high voltage circuit for supplying a high voltage to the X-ray tube, and an X-ray controller for generating a trigger signal for activating the X-ray generator; an imaging device including a charge coupled device for detecting an X-ray image of the intraoral region, said image device being provided in an intraoral region; an image processor for reading and processing an X-ray image detected by the imaging device, and displaying the processed image on a monitor; and a busy signal generating means for generating a busy signal indicating that the image processor is conducting processing of an X-ray image, said busy signal being sent to the X-ray controller during a processing period of the image processor, and when the X-ray controller receives the busy signal, supply of the high voltage is stopped and the trigger signal is not generated in response to the busy signal.
