Abstract:
Disclosed is a dual lens system having a light splitter and a method for capturing images. The system (200) comprises an optical element (204) configured to separate light (202) into a first light beam (208) and a second light beam (210); a first lens module (214) having a first focal length configured to focus the first light beam; a second lens module (220) having a second focal length configured to focus the second light beam, wherein the second focal length is different from the first focal length; a first sensor (216) configured to capture a first image from the first light beam focused by the first lens module onto the first sensor; and a second sensor (222) configured to capture a second image from the second light beam focused by the second lens module onto the second sensor. The FOVs, focal lengths, and/or sensors of the system may be designed to generate high quality images with arbitrary magnifications.
Abstract:
The prevent invention relates to an optical coupling device which comprises: an incidence part on which a ray of light emitted from a subject has a fixed angle of incidence; an emitting part which receives the ray from the incidence part and emits the ray at a fixed angle; and a connection part which transmits the ray on the incidence part to the emitting part so that the ray, which is emitted from the subject and is incident on the incidence part, may be transmitted to an observer of the subject by matching the angle of the ray with the fixed angle. Therefore, the objective of the present invention is to enable the observer to see an opaque object as a transparent object in the visible light spectrum or display the subject realistically through the emitting part.
Abstract:
A method for transmitting data to a camera without requiring in the camera a conventional wireless transmission capability includes (a) in the camera's field of view, providing an object which forms an image on which the data is encoded, (b) capturing an image of the object using optics of the camera, and (c) recovering the data from the image of the object. The data is encoded by an optically detectable quantity (e.g., light intensity or color) or a pattern in one or more portions of the object. The data can be earned by the distribution of the optically detectable quantity within the image or its derivative. The field of view of the camera may be divided into multiple sub-areas to allow providing multiple data-bearing images. A sequence of such images may be used to increase the amount of data that can be transmitted in this manner.
Abstract:
A sports activity system (10) for providing a memento (11) to a person undertaking a sports activity. The system (10) comprises a detector (14) and an imaging arrangement (18). The detector (14) is configured for detecting when an object (15) crosses a region (16) and the imaging arrangement (18) takes at least one image (20) in response to the detector (14) detecting the object (15).
Abstract:
A capsule camera apparatus includes a swallowable housing, a light source within the housing, a camera within the housing for capturing a first digital image and a second digital image of a view of the camera illuminated by the light source, a a motion detector that detects a motion of the housing using the first digital image and the second digital image, and a motion evaluator that selects a disposition of the second digital image, based on a metric on the motion. The disposition may include writing the second image into an archival storage or providing the second digital image to the outside by a wireless communication link.
Abstract:
Camera system and methods to capture panoramic imagery from a camera mounted on a moving platform, using low-cost digital image sensors. The panoramic imagery appears seamless and natural to the eye. The panoramic imaging system and methods are specifically designed to accommodate the long acquisition times of low-cost digital image sensors, despite the motion of the camera during image capture. Pairs of . cameras are arranged about an axis and a pairwise firing sequence enables capturing a series of adjacent images without gap or overlap. Additionally, when combined with suitable supplemental sensors, the image data provide location information about objects in the image for use in elementary photogrammetry.
Abstract:
A semiconductor memory device and an associated method suitable for use in specific applications with predictable memory access pattern, such as in a capsule camera. The memory device takes advantage of the memory access pattern to simplify address processing circuit to realize savings in power and silicon area. Because random access to the semiconductor device is not required, the interface from external to the semiconductor device is also simplified by eliminating at least the address port that is used to specify the memory locations accessed. The method is applicable not only to non-volatile memory technologies (e.g., flash memory), it is also applicable to volatile memory technologies, such as transient charge storage-based memory circuits (e.g., DRAMs) and metastable states-based memory circuits (e.g., SRAMs).
Abstract:
An optical viewing system (10) includes first (26), second (14) and third (16) image modifying devices together with an adaptor assembly (12) for connecting the image modifying devices together. The adaptor assembly (12) has first (22) and second (24) clamping portions. The first clamping portion (22) is connected to the first (26) and second (14) image modifying devices and the second clamping portion (24) is connected to the first clamping portion (22) and to the first (26) and third(16) image modifying devices so that the first image modifying device (26) is clamped between the second (14) and third (16) image modifying devices. At least one of the first (22) and second (24) clamping portions is removably connected to the first image modifying device (26) so that the first image modifying device (26) can be removed from the adaptor assembly (12) and operate as a further independent optical viewing system. Different combinations of image modifying devices can be arranged with one or more of the clamping portions.
Abstract:
A device for automatically determining the deviation between the structures of a pattern and those of an object compared therewith, in which the structures to be compared are viewed superimposed on a measurement gap, whereby a polarisation characteristic is given to the individual picture channels. As the result of the relative movement between the superimposed object picture and the measurement gap, and the subsequent separation of the picture channels according to their polarization characteristic, photometric signal curves are obtained from which errors in the overlap of the structures can be quantatively determined. By introducing a picture rotation prism, measurements can be made in two co-ordinate directions. In a branched observation beam path the polarization characteristic is converted into a colour characteristic, so that an additional representation of the combined picture of the structure overlap is produced. The photometric scanning range can be made visible by back-lighting of the measurement gap and reflection into the observation beam path.
