摘要:
An assembly (100) for the illumination of a wellbore, pipeline, tank, vessel or other environment wherein light is diffused and transmitted through an optically transparent material and projected in and around a field of view of a camera lens (10). A light source is disposed within a cavity at the proximal end (102) of a cylindrical shaped, optically transparent material. Light from the source is received into the transparent material, diffused, and transmitted to the distal end of the light tube (30), where it is projected in front of and around a field of view of a camera. Control of light intensity may be variable, pre-set before operations, or fixed by component design.

A method for controlling a lighting source in a capsule camera improves image quality by avoiding over-exposure or under-exposure in all regions of an image, while concurrently reducing significantly power dissipation in the capsule camera A capsule camera using the method includes (1) one or more sensor arrays each having one or more pixels in one or more designated regions in the field of view of the capsule camera, (2) lighting elements each providing illumination to one or more of the designated regions, and (3) a control unit that (a) extracts a parameter value from the pixels of each region, (b) evaluates the parameter value at each region, and (c) adjusts the lighting elements providing illumination to each region according to the evaluation The parameter value may be an average value of the pixels.
摘要:
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).

The invention relates to an image processing system, comprising an image recording device (10) with an imaging device (11) and an imaging surface (16); and a digital image storing device. A beam deviation device (17) with a reflecting surface (20) that is configured in the form of a cone envelope is located before the imaging device (11) in a beam path (22) which strikes the image surface (16). The axis of symmetry (21) of said reflecting surface is arranged in a defined manner in relation to the optical axis (18) of the image recording device (10). The image storing device is provided with a transformation device for transforming the projection of the cone surface produced on the imaging surface (16) by the beam deviation device (17) into an image file with image points projected onto the plane. The system is used for determining the profile of a cavity, and a panorama.
摘要:
An optical guide assembly for obtaining images of one or more exposed surfaces of an article that are at least partially immersed in a fluid. The optical guide assembly includes one or more sources of light, a camera, and an optical guide made of an optical medium. The light from the light source is reflected from the exposed surface to provide an initial light transmitted into the optical guide in a direction substantially orthogonal to a first surface thereof. The initial light is transmitted from the first surface through the optical medium to a second surface of the optical guide having a mirror thereon, to be reflected therefrom to provide a reflected light. The reflected light reflected from the second surface passes through a third surface of the optical guide substantially orthogonally thereto to the camera.
