摘要： A method of processing borehole log data to create one or more image logs involve modelling the log data as components of an image in the form i(x, y)=l(x, y)×r(x, y) (1), in which i(x, y) is an image representative of the log data, l(x, y) denotes an illumination value of the image at two-dimensional spatial co-ordinates x, y, and r(x, y) denotes a surface reflectance value at the co-ordinates x, y. Equation (1) is transformed to a logarithmic domain, and a Fourier transform is obtained of the resulting logarithmic domain expression to obtain a Fourier domain expression. The Fourier domain expression is high-pass filtered, and an inverse Fourier transform is obtained of the resulting filtered Fourier domain expression. An exponential operation is performed on the result of inverse Fourier transform to obtain a filtered image model expression. Values of the filtered image model expression are mapped to respective color values across the range of the filtered image model expression values. The mapped color values can then be displayed, printed, saved and/or transmitted as one or more image logs.

摘要： A catheter (12) has an image sensing system (S1-S5) for imaging the interior wall of a passageway in which the catheter is to be located. The catheter has a radial imaging system comprising a light source arrangement for generating a light output radially around the catheter and an image sensor for receiving the generally radial light after the light has been scattered back by the interior wall. The catheter is positioned within the passageway with a known position and orientation, for example a known angle with respect to the anterior-posterior plane along the length of the catheter, so that it is known where along the catheter length, and at which angular position around the catheter, it is close to the passageway wall. The light output has a different intensity at different radial directions and/or the catheter comprises a light transmission arrangement which gives rise to different transmission of the light output at different radial directions. These provide alternative measures to reduce the light received by the image sensor, thereby to prevent blooming in the captured image.

摘要： The invention provides an imaging system comprising an optical element for deflecting axially incident light into a series of axially spaced outward radial projections, and further comprising an image collection means for collecting reflected light. The element comprises a plurality of light deflecting surfaces or features which are arranged at axially successive points along the element, each at a different radial location. The light-deflecting surfaces are arranged to deflect light incident upon them from an axial direction in a radial direction, each thereby generating a radial projection of light from the element. A beam or beam bundle projected along the element has successive outer annular layers stripped by the facets and deflected outwards at different axial points along the structure.

摘要： The imaging device includes an image sensor that includes a plurality of pixels that generate an image signal from an object image that is formed by an imaging optical system, a scaling section that performs a scaling process on an original image that includes image signals that correspond to the plurality of pixels, and an output section that outputs an image after the scaling process as a scaled image, the scaling section performing the scaling process using a different scaling factor corresponding to the position of a pixel of interest within the scaled image, and the image sensor including pixels in a number larger than the number of pixels of the scaled image as the plurality of pixels.
