Isolated non-naturally occurring populations of spermatozoa (15) having high purity and technologies to differentiate spermatozoa (28) based on characteristics such as mass, volume, orientation, or emitted light including methods of analysis and apparatus such as beam shaping optics (30) and detectors (32).

A marker for a navigation system for determining the spatial position (e.g., of a surgical instrument), said marker including a retroreflective ball (12). A retroreflective surface (13) of the ball (12) is protected by a dimensionally stable, translucent or transparent shell (14) in such a way that the reflected image remains essentially uninfluenced in terms of contour and the position of the centre of gravity.

The present invention provides a projection device (10) which comprises:

• • at least two high resolution input channels (12, 14) for receiving a first and a second high resolution input signal (20, 22) having information data for a first and a second display format, respectively,
  • an image recombination system (24) for combining the high resolution input signals (20, 22) into one high resolution imaging signal having information data for a third display format larger than either of the first or second display formats,
  • a high resolution image forming display device (18) for displaying an image corresponding to the high resolution imaging signal, and
  • a projection lens (26) for projecting the imaged high resolution imaging signal onto a visualization surface (16).

The present invention also provides a corresponding method.

Due to the use of one large image forming display for displaying the two images, no geometrical alignment problem occurs. Because one single light beam is used for illuminating the one large image forming device, no colour non-uniformity problem occurs between the two images.

To provide an image processing system and the like which can correct a distortion in a projected image automatically and adequately, a projector has an area sensor section which senses a sensing region onto which an image is projected and outputs sensing information; a storage section which stores angle correction data in which the ratio of average luminance values for a plurality of different regions in the projection area is associated with derivation coordinates for deriving coordinates of the projection area, and also stores coordinate data indicating the derivation coordinates for the projection area; luminance-distribution analyzing section which refers to the angle correction data based on the sensing information and depending on the luminance distribution in the projection area and corrects the derivation coordinates in the coordinate data, based on the angle correction data; and a distortion correction section which corrects the image signals so that the distortion in the projected image is corrected, based on the coordinate data.

The image forming apparatus comprises: a recording head which ejects droplets of a liquid onto a recording medium; a droplet ejection control device which controls a droplet ejection timing of the recording head; and a conveyance device which relatively moves the recording medium and the recording head in a relative conveyance direction, wherein when the recording head performs ejection of a first droplet to form a first dot on the recording medium and then performs ejection of a second droplet to form a second dot overlapping with the first dot on the recording medium, the droplet ejection control device controls the droplet ejection timing of the recording head by taking a droplet diameter change time until a diameter of the first droplet deposited on a surface of the recording medium reaches D1b satisfying the following inequality as a droplet ejection time interval between the ejection of the first droplet and the ejection of the second droplet: D1b<2×Pt−D2a, where Pt is an interval between the first dot and the second dot on the surface of the recording medium, D2a is a diameter of the second droplet upon landing on the surface of the recording medium, and D1b is the diameter of the first droplet on the surface of the recording medium when the second droplet lands on the surface of the recording medium.

The present invention relates to a spectral domain optical coherence tomography apparatus having an endoscopic small-sized probe, and more particularly, to a technology imaging an external shape or an internal structure of a sample by a non-contact and non-invasive method by applying an optical coherent fiber bundle probe attached with a lens to Michelson interferometer or a Fizeau interferometer.

A method of processing an image for display on a television screen is described. Unlike conventional method which over-expands the image, the method described herein crops the image (optionally) and scales it to fit the native resolution of the display screen without over-expanding the image. The method includes the steps of receiving a source television image having a native image resolution, scaling the source television image using a scaling ratio to produce a scaled television image having a resolution equal to or less than the native screen resolution in both a vertical and a horizontal direction, and displaying the scaled television image on the television screen. The scaling ratio may be the same or different in the vertical and horizontal directions.

A real-time video enhancement method performed at a terminal includes: obtaining an average luminance of a current frame of an image; in accordance with a determination that the average luminance is less than the luminance threshold: obtaining a pixel range of an area of interest of the current frame; determining a local enhancement curve of the current frame according to the pixel range of the area of interest of the current frame; determining a first enhancement curve corresponding to the current frame according to the average luminance of the current frame; determining a second enhancement curve of the current frame according to the local enhancement curve of the current frame and the first enhancement curve of the current frame; and adjusting the current frame according to the second enhancement curve.

A display device includes a display panel in which a plurality of gate lines, a plurality of data lines, and a plurality of subpixels are disposed; a gate driver circuit driving the plurality of gate lines; a data driver circuit driving the plurality of data lines; and a controller controlling the gate driver circuit and the data driver circuit, wherein the display panel comprises a first active area in which N number of subpixels among the plurality of subpixels are disposed, and a second active area in which M number of subpixels among the plurality of subpixels are disposed and is located outside of the first active area, where the N is a natural number equal to or greater than 2, and the M is a natural number equal to or greater than 2, and wherein a first image and a second image are displayed on the subpixels disposed in the first active area, and the first image and a blank image are displayed on the subpixels disposed in the second active area.

A device and method for analyzing a sample provide for extracting a part to be analyzed from the sample with the aid of a previously generated opening in the sample. The part to be analyzed is examined in greater detail with the aid of a particle beam. For this purpose, the sample is placed in the opening or on a sample holder.
