A system and method for controlling the heat of an ultrasonic transducer is disclosed. The presently preferred embodiments of the present invention control the temperature of the transducer face by changing the imaging modes of the system. In a preferred embodiment, feedback from temperature sensing elements placed in the transducer is used to determine when to switch from a higher power imaging mode to a lower power imaging mode. In another preferred embodiment, the system switches from a higher power imaging mode to a lower power imaging mode after a predetermined period of time has elapsed. In yet another preferred embodiment, the system switches to a "mixed" imaging mode, where the system cycles rapidly between a higher power imaging mode and a lower power imaging mode, and the resulting data is combined to form a single image.

A method for selecting an emphasis image from a collection of images based on facial identification comprises the steps of: (a) obtaining a collection of digital images; (b) detecting image patterns indicative of the presence of one or more faces in the digital images, thereby identifying one or more detected faces for each image in which a face is detected; (c) recognizing one or more faces from the detected faces for each of the images in which a face is detected; and (d) scoring an image based on the relative frequency of occurrence of a recognized face within the collection of images, thereby producing an emphasis image characteristic of the most frequently occurring face in the collection of images.

The present invention is an imaging device which can be equipped with decode functionality and which can be configured to operate in at least one of four user selected modes. In a first, “message only” mode, the device stores into a designated memory location a decoded-out message corresponding to a decodable indicia. In a second, “image only” mode, the device stores into a designated frame storage memory location an image representation of a scene. In a third, “omage plu message” mode the device stores into a designated frame storage memory location an image representation comprising a representation of a decodable symbol and into the same or other memory location the decoded-out message decoded from the decodable indicia, or data corresponding to the same. In the fourth, “two-step message and image” mode, the device is controlled to capture an image a first time for decoding a decodable indicia and a second time for capturing an image that is associated with the decoded-out message corresponding to the decodable indicia.

The second imaging mode has an irradiation field different from the first imaging mode and has an area to be read in the digital X-ray sensor smaller than that in the first imaging mode.

In a light source unit, a switchable filter section in which an RGB filter and a fluorescence observation filter can be shifted into the light path is disposed in front of a lamp. When fluorescence image mode is selected, excitation light in a part of the wavelength band of the blue wavelength band is supplied to an electronic endoscope, and the excitation light which is reflected by the subject is shielded by an excitation light shielding filter situated in front of a CCD, whereby a fluorescence image can be obtained. On the other hand, if normal-light image mode is selected, then R, G, B light is supplied sequentially, and even under illumination of B light, the color component image in the wavelength bands which are not shielded by the excitation light shielding filter are captured, thereby yielding a normal-light image also, and hence making it possible to capture both a fluorescence image and a normal-light image by means of a single image pickup element.

A vehicle navigation system (e.g., GPS) with multi-use display generator that provides for the switching of a displayed image from a navigational based image to a non-navigational image such as a favorite photo. This versatility allows for the user of a vehicle navigation to avoid having to look at a boring display of map images and instead view more desirable non-navigation images such as full 100% displays of a favorite photo shot. Also if the system is in a map image mode and the user does not utilize any portion of the vehicle navigation system for a predetermined period of time an automated switchover system is provided to cause a predetermined or randomly chosen favorite photo to appear on the display. An addition option of the system is to provide an automatic switchover to the favorite display mode whenever a determination is made by the system that it will not be needed for a long period such as when the user is on a long country road or when the destination is inputted and there are no options that will arise for an extended period. Various display modes are also featured that enable greater non-navigation display mode options and activation choices.

The invention relates to a robust ear detection method which improves an AdaBoost arithmetic and belongs to the technical field of image mode identifying. The invention is characterized by proposing an ear detection method with excellent performances under a complex underground. The invention proposes four anisomerous Haar-like corner characteristics which are used for describing the grayscale changes on the partial areas of the ears; a policy of subsection selection is adopted for selecting the best sorting threshold of the Haar-like characteristics, thus reducing the sample training time; the weight of a weak sorter is modified for reducing the mistaken detection rate of the sorter; the threshold HW is set and eliminated according to the distribution change of the sample weight in the training, thereby preventing an over-studying phenomenon from being generated and leading the miss-detection rate and the mistaken direction rate of the ear detection to be reduced; besides, the invention also provides a single-ear detection policy for leading both the defection efficiency and the detection effect to be improved. The excellent performances of the robust ear detection method are shown on a PC machine and a DSP.

This invention provides a system and method for determining position of a viewed object in three dimensions by employing 2D machine vision processes on each of a plurality of planar faces of the object, and thereby refining the location of the object. First a rough pose estimate of the object is derived. This rough pose estimate can be based upon predetermined pose data, or can be derived by acquiring a plurality of planar face poses of the object (using, for example multiple cameras) and correlating the corners of the trained image pattern, which have known coordinates relative to the origin, to the acquired patterns. Once the rough pose is achieved, this is refined by defining the pose as a quaternion (a, b, c and d) for rotation and a three variables (x, y, z) for translation and employing an iterative weighted, least squares error calculation to minimize the error between the edgelets of trained model image and the acquired runtime edgelets. The overall, refined / optimized pose estimate incorporates data from each of the cameras' acquired images. Thereby, the estimate minimizes the total error between the edgelets of each camera's / view's trained model image and the associated camera's / view's acquired runtime edgelets. A final transformation of trained features relative to the runtime features is derived from the iterative error computation.

A display apparatus that can conserve power without compromising general display quality is presented. In a display system including a main control apparatus and a display apparatus, the main control apparatus generates an image control signal having an image data, and a main clock signal that changes from a first frequency to a second frequency in response to a change in image mode from a first image mode to a second image mode. The change from the first frequency to the second frequency includes changing through at least one intermediate frequency stage between the first frequency and the second frequency. By maintaining the change of frequency shift small (i.e., less than a predetermined maximum change), operation in emergency mode is avoided even when the frequency shift is sudden. The display apparatus receives the image control signal and the main clock signal to display an image.
