摘要:
The present invention employs a spectral and spatial combiner (132) that is capable of maintaining equal optical path lengths of each spectral beam so that a single combined bean (148) can be produced and can be employed in a number of different applications such as a color camera device (Figure 28), a color recording device (Figure 23), a graphics presentation device (Figure 27), an electronic color filter device (Figure 30), a color projector device (Figure 25) and a multi-channel optical communication device (Figures 31 and 33).
摘要:
An image reading device comprises a plural-line sensor containing plural one-dimensional sensor arrays formed on a substrate, a telecentric imaging optical system for forming the image of an object on the sensor, and a blazed diffraction grating positioned in the optical path between the imaging optical system and the sensor and adapted to separate the light from the object into plural color components and to guide thus color-separated lights to respectively corresponding the sensor arrays.
摘要:
Disclosed is an image reader for reading a color image by color separation, comprising; an image pick-up sensor having a plurality of line sensors respectively corresponding to separated colors, an image-forming lens system and a color separation device comprising a reflector element comprised of a dichroic mirror and a total reflecting mirror which are laminated interposing a transparent layer, wherein the color separation device is provided between the image pick-up sensor and the image-forming lens system.
摘要:
Apparatus having three interline area image sensors (24, 26, 28) each with a sparse array of elements. Each sensor is responsive to a different spectral region of a light image of a photographic negative. Each sensor element senses a plurality of light image pixels to produce analog signals. The light image is scanned in such a pattern between element exposures so that each digital image pixel has a nearest neighbor digital image pixel that was produced by a different sensor element. These analog signals are digitized (A/D) and arranged in a memory plane (60) to form a high resolution digital image.
摘要:
A color image processing apparatus wherein different color filters (45) are provided in an image pickup device (20) corresponding to plural groups of small pixels, each group of which is one unit of color pixels, and color image signals are obtained from the common position of the small pixel groups by suitably interpolating color image signals obtained from the small pixel groups.
摘要:
Die Erfindung betrifft einen polarisierenden Lichtstrahl-Kombinierer mit zwei entlang der jeweiligen Hypotenusefläche miteinander verbundenen Dreiecksprismen, wobei das erste Dreiecksprisma eine Lichteintrittsfläche und das zweite Dreickecksprisma sowohl eine Lichteintrittsfläche als auch Lichtaustrittsfläche aufweist. Erfindungsgemäß ist der Winkel (α) zwischen den beiden Schenkelflächen eines jeden Dreiecksprismas ungleich 90°.
摘要:
A color separator for an image scanner provides more than three colors. Three example embodiments are provided. Each embodiment incorporates a trichromatic dichroic beamsplitter (100), and a polarization filter (110). By inserting polarization coatings into the optical path, each spectral band from the dichroic coated optics is further divided into multiple spectra (figures 2A, 2B, 2C), thereby providing better color information. The polarization filter may be mechanically moved to insert one of two polarization areas into a light path (figure 1), or different rows of a photosensor array may be filtered by different polarization filters (figure 3), or an electronically controllable polarization filter may be used. In one embodiment, additional conventional color absorption filters are also inserted into the light path (figure 4). The spectral response of the dichroic layers in the beamsplitter is different than the spectral response of the color absorption filters.
