A device for imaging a relief object without illuminating a platen is disclosed. The device includes a single electrode electroluminescent device, which may be inorganic or organic, and a current source. The current source is coupled to the single electrode of the electroluminescent device and to the relief object to be imaged. The valleys and ridges of the relief object couple current to the electroluminescent device at different magnitudes which causes the electroluminescent device to generate light at different intensities that correspond to the ridges and valleys of the relief object. The generated light forms an image of the relief object which may be focused by optical elements onto a sensor array for capture and image processing. In another embodiment of the invention, a one-to-one sensor array is located proximate the electroluminescent device to capture the image. In an embodiment of the invention which insulates the relief object from current, the electroluminescent device is covered with a variable resistance layer and the variable resistance layer is covered with a flexible electrode. One lead from the current source is coupled to the flexible electrode and another lead is coupled to the single electrode. When a relief object is brought in contact with the flexible electrode, a localized pressures generated by the ridges of the relief object form conductive paths through the variable resistance layer which are lower in electrical resistance than those formed by pressure in the areas adjacent the valleys of the relief object. The different magnitudes of current delivered through the conductive paths to the electroluminescent device cause the electroluminescent device to generate an image of the relief object without exposing the relief object to electrical current.

Disclosed are a zoom lens and an imaging apparatus having a high zoom ratio, a small total length, and a small overall size. A zoom lens includes a first lens group having a positive refractive power, a second lens group having a negative refractive power, a third lens group having a positive refractive power, a fourth lens group having a negative refractive power, and a fifth lens group having a positive refractive power which are arranged in this order from an object side. A gap between the lens groups is changed to change power. The zoom lens satisfies the following Condition expression 1: 0.05<|f4| / ft<0.25   [Condition expression 1] (where ft indicates the focal length of the entire system at a telephoto end and f4 indicates the focal length of the fourth lens group).

A method of managing medical information is disclosed. Medical image data is received, at a real-time transfer engine, at the same time that the patient is being scanned by a medical imaging device. The medical image data is then converted to a browser-compatible image format at a converter engine connected to receive the medical image data from the real-time transfer engine. The converter engine comprises a decoder engine for extracting image pixel data from the medical image data and an encoding engine for converting the image pixel data to a browser-compatible format connected to receive the image pixel data. The image pixel data may be converted to a browser compatible format without loss of diagnostic data.

Systems and methods are provided for capture control of video data from a capsule camera system having an on-board storage or wireless transmission. The capsule camera system moves through the GI tract under the action of peristalsis and records images of the intestinal walls. For some periods of time, the capsule camera system may move very slowly and there are little differences in the image data between different frames. These frames can be designated for discard to conserve storage space or conserve power. A capsule control processing unit is incorporated to evaluate motion metric based on image data associated with a current frame and a previous frame. A decision is made based on a profile of the motion metric to select an operation mode from a group comprising Capture Mode and Conservation Mode. The capsule camera system is then operated according to the selected operation mode.

Methods and systems for scaling down a Web page image enables the image to be displayed on a standard television without horizontal scrolling of the image. A Web page image that initially has a horizontal dimension larger than the horizontal dimension of a television display is received from a web server and subsequently scaled down by a scaling factor that is based only upon the amount of scaling that is necessary to fit the image within the horizontal dimension of the television display. This scaling factor is used to scale the image horizontally and vertically, thus preserving the aspect ratio of the image. When a hyperlink from the scaled down Web page image is selected, coordinates to the hyperlink are scaled up based on the same scaling factor so that they will correspond with the server-side image map of the Web page image.
