1631 results about "Digital imaging" patented technology

Digital imaging or digital image acquisition is the creation of a digitally encoded representation of the visual characteristics of an object, such as a physical scene or the interior structure of an object. The term is often assumed to imply or include the processing, compression, storage, printing, and display of such images. A key advantage of a digital image, versus an analog image such as a film photograph, is the ability make copies and copies of copies digitally indefinitely without any loss of image quality.

InactiveUS20060114338A1Facilitate embedding informationTelevision system detailsColor television detailsUser verificationDigital imaging
A digital imaging device and method for embedding and retrieving of information in digital images are provided. The digital imaging device includes a capture module for capturing an image and creating a digital image file; a locational information module for determining a location of the device when capturing the image; and a processing module for associating the location information to the digital image file. The device further includes a user verification module for verifying an identity of a user of the device at a time of image capture and an encryption module for encrypting the digital image file and associated information. The method provides for securing information associated with the digital images and for verifying activities of a user.

Method and apparatus for the automatic real-time detection and correction of red-eye defects in batches of digital images or in handheld appliances

An automatic, red-eye detection and correction system for digital images capable of real-time processing of images, including a red-eye detector module that determines without user intervention if a red-eye defect exists. If a defect is located in an image the portion of the image surrounding the defect is passed to a correction module that de-saturates the red components of the defect while preserving the other color characteristics of the defect region. The invention is designed to minimize the computational resources required to detect and correct red-eye defects and thus is particularly suited to applications requiring real-time processing of large volumes of digital images prior to acquisition or printing. This system can operate on images stored on personal computers, commercial printers or inside digital cameras as part of the acquisition process, or prior to display on personal digital assistants, mobile phones and other digital imaging appliances.

Method and system for ablation of atrial fibrillation and other cardiac arrhythmias

A method is provided for ablation in treatment of heart arrhythmias such as atrial fibrillation that includes positioning a catheter apparatus with multiple electrodes within a cardiac chamber, visualizing the catheter apparatus with an interventional system, navigating the catheter apparatus within the cardiac chamber, and delivering energy to selected electrodes of the catheter apparatus from an external source to ablate heart tissue at select locations. Preferably, the external source is an external patch placed on the patient for the delivery of radio-frequency energy. The electrodes of the catheter apparatus are connected to the patch through a patient interface unit where the interface unit selects the electrodes to which radio-frequency energy is to be delivered. In another aspect of the invention, a system for ablation of heart arrhythmias is provided that has a catheter apparatus with multiple electrodes, an interventional system for visualizing the catheter apparatus within a cardiac chamber, and an external source for delivering energy to selected electrodes of the catheter apparatus within the cardiac chamber to ablate heart tissue. Preferably, the system further includes a digital imaging system for obtaining cardiac image data, an image generation system for generating a 3D model of the cardiac chamber from the cardiac image data, and a workstation for registering the 3D model with the interventional system and for visualizing the catheter apparatus over this registered 3D model upon the interventional system.

Apparatus and method for digital imaging, education, and internal marketing software and system

A method and system for automatically managing multiple different functions of an office by storing or linking together multiple different types of data that is normally stored separately, such that summary reports requiring data from fields normally not stored together can be created efficiently and effectively, and a method and system for automatically selecting client education, marketing or other business-related information or materials from a stored collection of such information or materials based on selection criteria established by the business, such that the selected information or materials are targeted to the specific client based on demographic and other client information and scheduling and other business information. In one aspect of the invention, a patient education module has a library of content on hand. The information and materials play automatically to a designated monitor near the location of the client and the material viewed is documented in the client's electronic record with customized notation by user. The material viewed has a supportive component hand-out or supportive accompanying written information that is automatically printed at the receptionist desk at the time the material is viewed on the monitor by the client.

Method and system for scanning an image using a look-down linear array scanner

A system and method are disclosed which provide a look-down digital imaging device capable of capturing relatively high resolution digital images (e.g., comparable to traditional flatbed scanners). A preferred embodiment provides a look-down digital imaging device comprising a linear sensor for imaging a raster line of an original image placed substantially below the look-down digital imaging device, and a lens for focusing reflected light from the original to such linear sensor. The linear sensor functions much as in traditional flatbed scanners in that it captures a single, congruent digital image of a scanned original. Most preferably, the linear sensor is a high resolution sensor that enables a digital image to be captured having resolution comparable to that of traditional flatbed scanners. For instance, the linear sensor preferably enables capture of a digital image having a resolution no less than approximately 300 dpi. As a result, such linear sensor most preferably captures a digital image having sufficient resolution to permit optical character recognition operations to be performed on such captured image. In a most preferred embodiment, the look-down digital imaging device further comprises a digital video camera for capturing video data of a target scan area. Such video data may be fed in substantially real-time to a display (either included within the look-down digital imaging device or included on a device to which the look-down digital imaging device is coupled), which may aid a user in properly aligning an original within the target scan area.

Method and system for determining and maintaining trust in digital image files with certifiable time

A system and methods for proving dates of digital-imaging files, which are accessed, created, modified, received, saved, or transmitted by a computer includes a trusted time source in a tamperproof environment, a first subsystem for saving the file at a moment in time, a second subsystem for retrieving from the trusted time source a date and a time corresponding to the moment in time, a third subsystem for appending the date and the time retrieved from the trusted time source to the saved file, a fourth subsystem for signing the saved file with the date and the time retrieved from the trusted time source appended thereto, a fifth subsystem for hashing the signed file to produce a digest, a sixth subsystem for signing the digest with a key to produce a certificate, a seventh subsystem for appending the certificate to the saved file, and an eighth subsystem for saving the file with the certificate appended thereto. The trusted time source is a real time clock, which is not resettable, is independent of any system clock of the computer, and is installed locally relative to the computer.
