Scanning apparatus for generating signals representing color components of successively scanned picture elements of an original colored image comprises a light source (1); means (42,45) for causing relative movement between the original image (3) and a light beam generated by the light source (1) whereby successive picture elements of the original image are scanned. Means (13) for generating a sharp light beam for each color component of each element and an unsharp light beam for at least one co...

An image fiber in which the contrast of the viewed image is improved. The image fiber of the invention is composed of a plurality of optical fiber cores with a cladding layer provided around the cores and filled into the spaces between the cores. A primary coating covers the cores and cladding layer. The primary coating contains a light-absorbing substance, for instance, carbon particles. Preferably, the primary coating is composed mainly of silicone resin.

This invention provides parallel partial image processing such as spatial convolution or non-linear neighbor arithmetic operation using an image processor which can easily be formed as a large-scale integrated circuit and can be used for various purposes. The image processor has an adder-subtractor, a multiplier, a reciprocal number memory in which the reciprocal of an address and the amount of shift are stored at each address, and a shift register. The processor therefore is capable of high-spe...

An iconic-to-iconic low-level image processor is provided which comprises a lurality of identical sequential intermediate stages located between an input stage adapted to be connected to image sources such as analog or digital television cameras, ranging devices and conformal mapping arrays and an output stage adapted to be connected, e.g. to monitors, robot vision systems, iconic symbolic mapping devices and image processing computers. The intermediate stages are provided with forward pathway c...

An image intensifier has a phosphor screen, the phosphor screen having a mesh-like substrate and a phosphor layer supported by the mesh-like substrate and to be excited by electron rays. The image intensifier provides an output image with high contrast and brightness.

An image sensor for generating multi-bit digital pixel values for analyses in a digital image processor. A phase detector is utilized for detecting the relative phase difference between a modulation reference waveform for modulating a light source and the reflected information waveform from the illuminated target area. A high speed digital counter is driven by a phase locked loop frequency multiplier. The counter is enabled and reset by digital logic levels derived from the reference and signal ...

An image processor for reproducing a continuous tone image such as a photograph in a black-and-white binary dot image (halftone image) has a linear correction section for converting a sampled digital image signal in a predetermined manner controlled by black and white densities of an original, thereby performing linear conversion between the continuous tone image and the halftone image. The image processor also has another correction section for performing profile emphasis to obtain a clear half...

In the image sensor, thin film transistors are provided in the one-to-one correspondence to the photoelectric conversion element these thin film transistors being divided into blocks of adjoining ones whose gate electrodes are mutually connected, and the switching signal is sequentially supplied to each mutually connected gate electrodes of the same block. Further, the output electrodes of those thin film transistors located in the corresponding positions in each odd and even numbered blocks are...

An optical or photon image is converted by a photocathode to an electron ge. A semiconductor plate receives the electron image on a first side thereof. For an electronically controlled time, the image is integrated and stored in thousands of reversed biased PN junctions connected to micro-sized conductors, in the plate. An intensified image is then transfered from a second side of the plate at an electrically controlled time to adjacent moving film which is exposed to intensified images from the...

The invention comes within the domain of synthetic images on a cathode scn and concerns a digital memory whose contents are cyclically read to constitute an image on the screen. The memory is divided into blocks each of which contains the data of a part of the image and which are cyclically controlled in such a way that within a line of the image, the blocks are read successively, whereas at the end of a line, a block is skipped. Thus, possible blanks in the image due to the breakdown of one of ...
