A method for transforming an original image to a new image is provided. The original image includes M rows of original data; the new image includes Q rows of new data. The method first generates a (2i−1)th row and a (2i)th row of intermediate data respectively based on the (2i−1)th row and the (2i)th row of original data. Then, the method generates a (2i+1)th row and a (2i+2)th row of intermediate data respectively based on the (2i+1)th row and the (2i+2)th row of original data. During the process of generating the (2i+1)th row of intermediate data, the (2j−1)th row of new data is simultaneously generated based on the (2i−1)th row and the (2i+1)th row of intermediate data. During the process of generating the (2i+2)th row of intermediate data, the (2j)th row of new data is simultaneously generated based on the (2i)th row and the (2i+2)th row of intermediate data.

An optical system for a color television camera comprises a beam-splitting arrangement for separating an incident light beam from a main objective lens into three partial beams corresponding respectively to three different parts of the visible spectrum, the three partial beams being supplied to the photoelectric cathodes of respective camera tubes. One of the partial beams is supplied to the respective photoelectric cathode by way of an intermediate lens, so that the size of the image on the photoelectric cathode is different from the size of the images on the other two photoelectric cathodes. A deflector is added to allow placement of the reduced image size camera tube perpendicular to the main objective lens.

A color television camera comprises two camera tubes and optical means splitting an incident light beam into three partial beams corresponding respectively to three different parts of the visible spectrum, the green or luminance partial beam being supplied to one of the camera tubes and the red and the blue partial beam being supplied to the other camera tube. The red image is mirror inverted with respect to the blue image; the blue image and the red image are both scanned by one electron beam of said other tube.

Apparatus for producing a plurality of images of different colors from a polychromatic image comprising an image dissector which splits the image into separate beams, a dispersing prism dispersing the beams into beams of differing colors and a light guide designed to the dissector and prism to gather the beams of each individual color and combine same into a colored image at the output end of the light guide.

This disclosure depicts method and apparatus for the optical detection at distinct detection planes of a plural number of distinct images from a record encoded with a plurality of superimposed images multiplied, respectively, with a unique spatially periodic modulation. More particularly, this disclosure depicts method and apparatus for optical image detection which is especially useful in color television film reproduction, simultaneous color separation photography, or the like. The depicted method and apparatus involves Fourier transforming a modulated record to separate in optical channels in transform space spatial frequency spectra of stored images encoded on the record, spatial filtering the transform pattern, and simultaneously detecting distinct images carried in the separated optical channels. Cathode ray pickup tubes and photosensitive emulsions are shown and described as alternative ways for separately photodetecting the images carried in the respective channels formed.

In a color television camera, a color separation optical system includes a first relay lens behind a taking lens of the camera, color separation optical elements such as prism blocks or dichroic mirrors, and a set of second relay lenses. Image pick-up tubes for three colors are provided behind the second relay lenses. The pick-up tubes are mounted in coil assemblies. Each coil assembly is provided with a rotating device for conducting a position adjustment of the tube with respect to the associated second relay lens to make perfect registration between images of the three tubes. A focus adjusting device for conducting a focus adjustment between each second relay lens and the associated image pick-up tube is provided in each second relay lens. The focus adjusting devices are operable from outside the camera for sliding the second relay lenses in the direction of their optical axes.

First, second and third signal level comparators are used to compare against a predetermined signal level respective ones of the red, green and blue color signals generated by a television camera. The outputs of the comparators are combined in an AND gate to ascertain when an essentially black or essentially white signal obtains. When such signal is present, the differences between red and green color signals and between blue and green color signals are reduced by servomechanisms.

In a color television image pick-up device the light received through an objective lens is divided to follow two discrete paths, a part of the light being supplied to a brilliance image pick-up and the other part of the light being supplied through a Magenta filter to a chromaticity image pick-up tube including a stripe filter formed on the inner surface of a face plate and consisting of alternate monochromatic portions of red or blue color and transparent portions, thus obtaining color television signals from the output from two image pick-up tubes.
