Intra-oral camera with integral display
First Claim
1. A portable intra-oral capture and display system, said system comprising:
- a handpiece elongated for insertion into an oral cavity, said handpiece including a light emitter on a distal end thereof for illuminating an intra-oral object in the cavity and an image sensor for capturing an image of the intra-oral object and generating an image signal therefrom;
a portable, hand-cradled base flexibly tethered to the handpiece such that the base may be hand positioned relative to a user'"'"'s line of sight without moving the handpiece, said base containing in a single integral enclosure a light source for generating light, electronics for processing the image of the intra-oral object for display, a display monitor for displaying the image of the intra-oral object, a storage for storing the image of the intra-oral object, thereby providing a stored image of the intra-oral object for subsequent review and access, and an interface for transferring the stored image of the intra-oral object to a peripheral device;
wherein the base further includes interface electronics for transferring the stored image to the peripheral device through the interface, retrieving one or more stored images from the peripheral device through the interface and displaying the retrieved stored images on the display monitor, and a set of user controls for allowing the user to enable the interface electronics to transfer the stored image to the peripheral device and to retrieve the one or more stored images from the peripheral device; and
an optical connection for transmitting the light from the base to the light emitter in the camera, and an electrical connection for communicating the image signal from the image sensor in the camera to the electronics in the base.

10. A dental image processing system comprising:
-
a portable intra-oral camera and display system connected by a wireless link to one or more peripheral processing devices remote from the camera and display system; wherein said portable camera and display system comprises; a handpiece elongated for insertion into an oral cavity, said handpiece including a light emitter on a distal end thereof for illuminating an object in the cavity and an image sensor for capturing an image of the object and generating an image signal therefrom that is calibrated for the colorimetry of the camera and display system; a portable, hand-cradled base containing in a single integral enclosure electronics for processing the image for display, a display monitor for displaying the image and a wireless device for establishing the wireless link and transmitting the image from the base to one or more peripheral devices located remote from the intra-oral capture and display system; a connection for communicating the image signal from the image sensor in the camera to the electronics in the base, where the connection allows the handpiece and the base to be independently movable with respect to each other; and wherein the dental image processing system provides color calibration across the entire dental image processing system, whereby the handpiece is used to illuminate target materials to characterize a characteristic input color response of the portable intra-oral camera and display system and whereby the color calibration further includes characterization of a characteristic color response of one or more output devices, including one or more of the peripheral devices that render the image. - View Dependent Claims (11, 12, 13, 14, 15, 16)

21. A method for capturing pictorial images of the interior of a patient'"'"'s mouth in order to provide a diagnosis of dental and oral disease as well as a visual record of the condition of the patient, said method comprising the steps of:
-
providing a handpiece component that is elongated for insertion into the patient'"'"'s mouth, said handpiece component including a light emitter on a distal end thereof for illuminating dental structure in the mouth of the patient and an image sensor for capturing an image of the dental structure and generating an image signal therefrom; capturing a pictorial image of the interior of the patient'"'"'s mouth, including the dental structure, by placing the handpiece component in proximity to the dental structure; providing a hand-sized base component that is easily cradled, supported and held by one hand, said base component containing in a single integral enclosure an electronics stage for processing the image of the dental structure for display, a display monitor for displaying the image of the dental structure, and a storage for storing the image of the dental structure, thereby providing a stored image of the dental structure for subsequent review and access; providing a transfer interface between the handpiece component and the base component that allows each component to be independently movable with respect to the other component, said transfer interface being adapted to transfer the image of the dental structure between the handpiece component and the base component; transferring the pictorial image of the dental structure from the handpiece component to the base component over the transfer interface; displaying the pictorial image of the dental structure on the display monitor of the base component; and manipulating the hand-sized base component relative to the handpiece component such that one person may capture the pictorial image of the dental structure with the handpiece component held in one hand while positioning the base component in the other hand for best viewing of the displayed image. - View Dependent Claims (22, 23, 24, 25)
