Systems and methods are providing for capturing images of objects or faces without previewing the image to be captured. In particular, systems and methods are provided for using a detection algorithm to determine when a camera lens of an electronic device is properly oriented to capture an item (e.g., a face in a self-portrait). The detection algorithm can be configured to identify specific faces or objects, and can direct the electronic device to automatically store a captured image in response to detecting objects or faces of interest. In some embodiments, a motion-sensing component can be used to help align the lens.

A medical imaging system generates 3D anatomical images from acquired 2D anatomical images. The system includes a synchronization processor for providing a synchronization signal identifying a particular phase of heart operation of a particular patient. An image acquisition device acquires 2D anatomical images of a patient heart in angularly variable imaging planes over multiple different heart cycles at the particular phase of heart operation in response to the synchronization signal and in response to recorded data indicating imaging previously being performed at particular imaging plane angles. An image processor stores the recorded data to prevent imaging overlap at the particular imaging plane angles and to prevent unnecessary radiation exposure of the patient. The image processor processes 2D images acquired by the image acquisition device of the patient heart in multiple different imaging planes having relative angular separation, to provide a 3D image reconstruction of the patient heart

A method is provided for computing a composite image representing a focused image of an object in an application of machine vision in an optical inspection system. An image tessellated into focus regions is evaluated by region for fine feature sharpness. A sharpness image is computed for each focused region using a fine feature sharpness measurement. A focused composite image is computed by combining as a weighted average, the images at several focus settings, using the sharpness image at each focus setting as the weight. The focused composite image can be further analyzed, inspected, or otherwise processed.

A scanning device for biological slides is provided, which can be operated in an interactive routine mode as well as in an unsupervised high speed automatic mode. In the first case, typical components, which the pathologist is used to operating manually, such as the microscope, the stage and the focus, and which have to be motorized for the automatic unsupervised system mode, are configured to simulate manual use, operation, and response. A non-interlaced area scan camera supports the interactive selection and acquisition of individual images in the manual mode, as well as the continuous high-speed scan motion for the rare event detection and virtual slide scan applications of the system. Due to the particular requirements to accommodate both operational modes, methods are described for constructing the virtual slide out of image tiles with varying overlap areas in the x- and y-directions.

An all-white reference subject is imaged by a CCD and image data representing the reference subject is obtained. The position of any dust on the reference subject represented by the reference-subject image data is detected by a dust position detector. Address data representing the position of the dust is stored in a memory that stores dust address data. When the user images a subject, image data obtained by such imaging is input to a dust correction circuit. The dust address data is read from the memory and the image at the position represented by this dust address data is eliminated from the image of the subject by reason of the fact that the image at this position is that of dust.

The present invention is to provide a denoise method on Gaussian/Laplacian image pyramid, which integrates Pyramid analysis/synthesis algorithm, MMSE (minimum mean square error) filter and NL (non local) filter on the image pyramid to reconstruct and output a denoised image of an original input image through a plurality of iterative procedures, and utilizes an auto-adaptive noise estimation algorithm to find parameter of noise level used by the NL filter, so as to be easily embedded in mobile or handheld devices for obtaining better noise removing and anti-shaking results and remove noise much faster than the conventional denoise method, but only with less quality loss.

The apparatus employs the remote field eddy-current (RFEC) inspection technique to electromagnetically measure physical parameters of a metallic pipe. RFEC devices inserted into and displaced along a cylindrical pipes may be used to measure the ratio of pipe thickness to electromagnetic skin-depth and thus allow for the non-invasive detection of flaws or metal loss. Typically these RFEC thickness measurements exhibit a so-called double-indication of flaws, an undesired artifact due to a double-peaked geometrical sensitivity function of the device. The method describes a means by which this double indication artifact may be removed by an appropriate processing of RFEC measurements performed by an apparatus specifically designed for this purpose. The invention is particularly well designed for applications in the oilfield industry.

Manufacturing lines include inspection systems for monitoring the quality of parts produced. Manufacturing lines for making semiconductor devices generally inspect each fabricated part. The information obtained is used to fix manufacturing problems in the semiconductor fab plant. A machine-vision system for inspecting devices includes a light source for propagating light to the device and an image detector that receives light from the device. Also included is a light sensor assembly for receiving a portion of the light from the light source. The light sensor assembly produces an output signal responsive to the intensity of the light received at the light sensor assembly. A controller controls the amount of light received by the image detector to a desired intensity range in response to the output from the light sensor. The image detector may include an array of imaging pixels. The imaging system may also include a memory device which stores correction values for at least one of the pixels in the array of imaging pixels. To minimize or control thermal drift of signals output from an array of imaging pixels, the machine-vision system may also include a cooling element attached to the imaging device. The light source for propagating light to the device may be strobed. The image detector that receives light from the device remains in a fixed position with respect to the strobed light source. A translation element moves the strobed light source and image detector with respect to the device. The strobed light may be alternated between a fit and second level.

The present invention discloses a method and an apparatus to compute a complex wavefield, referred to as the object wave o, by means of measuring the intensity signal resulting from the interference of the said object wave with a second wave termed the reference wave. The second wave r is assumed to have some non-vanishing mutual coherence with the said object wave o. The reference wave can be obtained from a source or from the object wave itself. The wave may be emitted from sources of variable degree of coherence and can be scattered waves, but also light-emitting molecules, matter waves such as electron beams or acoustical sources. The disclosed method relates to the said “non-linear method” (NLM). The innovation resides in the fact that the NLM improves considerably the bandwidth of the wavefront reconstructed from off-axis interferograms and holograms obtained in a single shot. The advantage is the significant improvement of the resolution of the images obtained from the reconstructed wavefront, i.e. amplitude and phase images. The said method also suppresses the artifacts resulting from the intensity recording of interferograms and holograms. The method is general in the sense that it can be used for any interferometric measurement, provided that it satisfies the simple requirement that the intensity of the reference wave is larger than the intensity of the object wave, and that the object wave modulated by the reference is confined to at least a quadrant of the spectrum. The disclosed method applies to interferometry, holography in optics, electron waves and acoustics. In particular, it can be implemented in phase, fluorescence, luminescence, electron and acoustic microscopy.

A three-dimensional display method and a device therefor are provided in which a number of images can be displayed in the horizontal directions while image skips can be eliminated by providing overlaps of display angular ranges between adjacent images having horizontal display directions.

A number of images are displayed in horizontal and vertical directions so that the display directions do not agree with each other, and by expanding vertical display angular ranges of entire images with a vertical-direction diffusion plate (17), a vertical display angular range common to the entire images is generated. In this common vertical display angular range, the entire images have different horizontal display directions. Thereby, a number of images can be displayed because image generating sources can be arranged also in the vertical direction in addition to the horizontal directions.

A camera module includes a module structure constituted by a lens unit to which an image pickup lens is attached and a package to which an imaging element is attached so as to be opposite to the image pickup lens. An optical filter is arranged between the imaging element and the image pickup lens. A portion of a flat surface of the optical filter is fixed to a filter fixing portion via an adhesive. The optical filter is adhered to the filter fixing portion in a state in which an end portion formed by a side surface of the optical filter and the flat surface is in noncontact with the filter fixing portion or the adhesive. Minute particles generated from a cut surface of the optical filter fall outside the filer fixing portion.

A semi-automatic system for scanning a document includes an image capture device, such as a digital or video camera, which records a sequence of images while a user waves a document in front of the device. The user can present multiple pages of a document to the image capture device, after which the total sequence of images are processed to identify a clear image of each page from the sequence of images. The system further includes image processing techniques to correct for motion blurring, acceleration and perspective errors. The system is capable of processing any size or shape of document without destroying the organization or format of the original.

For binarizing an image, which is composed of pixels, the image is split into two semi-images. Local parameters are initialized based on values of pixels that lie in an area adjacent to a boundary separating the semi-images. A binarization is then performed separately for each of the semi-images using an adaptive threshold, wherein the adaptive threshold is calculated for each of the semi-images proceeding from the initialized local parameters.

The present invention provides reduces the number of required synthesizers thereby reducing the area and power concerns to extract/insert a signal from/to a multi-channel communication system and is also known as frequency planning. The highest frequency of operation required for the synthesizers or oscillators is approximately the midpoint of the entire signal frequency range. Two superimposed Weaver architectures are used to form the architecture. The receiver extracts the baseband I and Q signals from the multi-channel communication system, while the transmitter upconverts the baseband I and Q signals to the multi-channel communication system. The Weaver architecture, depending on the select bit, can enhance the image signal and reduce the desired signal or the image signal can be reduced while the desired signal is enhanced. Because the image and signal components are symmetrically displaced from the RF LO, less IF LO frequencies or synthesizers are required to operate the system.

A light-diffusing film comprises a light-diffusing layer (e.g., an anisotropic light-diffusing layer), and the light-diffusing layer comprises a continuous phase comprising a polycarbonate-series resin (a polycarbonate-series resin having a number average molecular weight of 15000 to 25000) and a dispersed phase comprising a polypropylene-series resin (a metallocene-catalyzed polypropylene-series random copolymer). A transparent layer may be laminated on at least one side of the light-diffusing layer. The light-diffusing layer may substantially be free from a compatibilizing agent. In spite of a use of the polycarbonate-series resin, the dispersed phase can uniformly be formed. Therefore, the film is suitable for a member of a plane light source device or a display apparatus. The light-diffusing film inhibits a change in a light-diffusing characteristic even under a high temperature.
