Abstract:
The present invention relates to the correction of planar focus in an electronic still or video camera. The camera includes: a detector array an objective lens arranged to direct optical radiation from an object plane onto the detector the lens defining an optical axis of the camera and the object plane being at an oblique angle to the optical axis movement device to change the relative orientation of the detector with respect to the lens so that the detector and lens may be moved relatively toward or away from each other along the optical axis and also tilted with respect to each other with at least one degree of freedom and focus detection device connected to the detector to detect when a portion of an image falling on the detector is in focus. The camera also includes a processor device to control the movement device according to the detected focus, the processor device bringing the image into focus on the detector by first changing the relative orientation of the lens and detector until a first portion of the image is in focus, and then holding said first portion in focus whilst continuing to change the relative orientation of the lens and detector until a second portion of the image is also in focus.
Abstract:
A stand facilitates and supports the use of digital cameras including digital video cameras in performing an equivalent function to a scanner in recording digital images which may be downloaded to a computer. The stand incorporates means for automatically configuring the camera into a mode of operation for document image capture on placing said camera into said stand. Said stand is adjustable in height and includes hinge sections 201 to appropriately position said camera for use in capturing an image of a document.
Abstract:
A method of automatically selecting regions of interest within an image in response to a selection signal, and panning across an image so as to keep the selected region in view is disclosed, together with an image processing system employing the method.
Abstract:
A digital camera has first and second light sources for sequentially illuminating a document from two different directions in response to the camera being activated. The camera has first and second sensor portions. Only the first and second sensor portions respectively respond to images reflected from the document in response to the first and second sources illuminating the document. Images detected by the first and second sensor portions are combined to remove specular reflection from the document image. In a second embodiment, the camera has three sensor portions.
Abstract:
A computing apparatus comprises a processor unit 10 and a foot control unit 13, in addition to a device for presenting information to a user such as a microdisplay. Movement of the foot, which drives operation of a selection element, provides user input to the processor unit. The foot control unit contains a position sensor 27 that detects position relative to a reference unit 26 in the processor unit 10. A stream of relative position data is used to indicate alternative options at the information presentation device. Selection may be carried out by various alternative methods in different embodiments —if the position sensor 27 is also an orientation sensor, this may be by rotation of the foot. This arrangement is particularly suitable for a wearable computing apparatus.
Abstract:
The present invention provides a computer system (2) for determining regions of interest in a static digital image for display on a display device, the system comprising a processor (4) configured to compare parts of an image (20, 50) with characteristics at least one region of interest specified by a user (19) and to determine at least one region of interest in an image (20, 50) based at least in part on the degree of similarity between parts of the image and the at least one user-specified region of interest in which the at least one user-specified region of interest is specified from the same image as the image in relation to which the determination is made.
Abstract:
Systems and methods are provided for building a complex document. A system can include a memory for storing computer executable instructions and a processing unit for accessing the memory and executing the computer executable instructions. The computer executable instructions can include a graphical user interface engine to display a target complex document browser and a plurality of source complex document browsers, such that elements and containers contained within a complex document displayed by each of the source complex document browsers are copyable into the target complex document browser in response to user input information to build a new complex document.
Abstract:
A system for arranging a number of images into a compilation of images a metadata derivation unit (230) configured to derive metadata from the images based on the content of the images, and an image arranging unit (240) configured to arrange the images into a compilation of images based on the metadata derived from the images. A method for arranging a number of images into a compilation of images is also provided.
Abstract:
The reading of data from a memory tag to another device, using a memory tag reader, is described. The other device has an active portion which can detect the presence and position of the memory tag reader when brought adjacent to it. The memory tag reader is brought adjacent to the memory tag and data uploaded into the memory tag reader. The memory tag reader is moved adjacent to the active portion of the other device into a position which identifies the location to which the data is to be transferred. The data is then downloaded into that location in the other device. A similar process is described for downloading data from the other device to the memory tag. Apparatus appropriate to carry out each stage of these processes is described.
Abstract:
A digital camera derives an infrared and visible signals from IR and visible sensors. The sensor fields of view overlap or share a common field of view. An analyzer of the IR signal provides the location of and information from an active or passive IR target. The analyzer responds to the location and information signals for visible image composition control (pan/tilt/zoom/timing) and selection of visible image pictures for storage to provide ancillary information, such as personal details of a target wearer. The visible and infrared image signals are combined to correct for sensitivity of the visible and/or IR sensors to IR and visible wavelengths, respectively.
