Electronic recording and communication of information

An image processing system for optical systems including microscopes which separately captures (grabs) different portions of the electromagnetic spectrum as emitted from an object as separate images. Each of the separate images are individually focused and then aligned with the other images to produce a composite image. In one embodiment, the different portions correspond to red, green, and blue and the composite image is displayed to the user on as a monitor without any need for an eyepiece.

Optical system and method for composing color images from chromatically non-compensated optics

In a method for matching two images, each consisting of a plurality of pixels and having partially overlapping contents, the degree of correspondence between the contents of the images is determined for different displacement positions representing different overlappings of the images. More specifically, a plurality of numbers are determined for each one of a plurality of said displacement positions. Each number is formed with the aid of pixel values from both images and is used to simultaneously retrieve predefined overlap assessment values for at least two of said displacement positions. The overlap assessment values retrieved are subsequently used to determine the degree of correspondence between the images for the different displacement positions. The method is carried out with the aid of a computer and can be implemented as a computer program.

Method and a device for matching images

In a method for recording a selected sequence of characters with the aid of a pen, the latter is passed over the sequence of characters and a plurality of images, whose contents partially overlap, are recorded simultaneously with the aid of a light-sensitive sensor ( ) with a two-dimensional sensor surface. The recorded images are put together, horizontally as well as vertically, into an image. Subsequently, the characters in the composite image are identified and stored in the pen with the aid of a predetermined character code formal. The putting-together, the character identification, and the storing are carried out with the aid of a signal processing unit ( ). By the method and the pen compensation is obtained for different speeds of movement and different angles of rotation of the pen.

Recording method and apparatus

Recording of information

A fingerprint identification/verification system using bitmaps of a stored fingerprint to correlate with a bitmap of an input fingerprint, wherein an accurate reference point is located and selected two-dimensional areas in the vicinity of the reference point of the input image of the fingerprint are correlated with stored fingerprint recognition information to determine if the input fingerprint image and the stored fingerprint recognition information are sufficiently similar to identify/verify the input fingerprint.
