Provided is a thermal barrier film having, dispersed in a resin matrix, high-refractive-index particles having a D-line refractive index of 2.5 or more and 3.2 or less. The high-refractive-index particles have an average particle size of 2.0 &#x3bc;m or more and 5.0 &#x3bc;m or less. Provided are a thermal barrier film that reduces a temperature rise due to sunlight by virtue of having a high reflectance even as a thin film, has high film thickness accuracy, and has high abrasion resistance, a thermal barrier paint for forming such thermal barrier film, and an optical instrument including such thermal barrier film.

Thermal barrier film, thermal barrier paint, and optical instrument

A process of producing a thin film is disclosed. The process comprises the steps of providing a vessel; placing a target such that a surface to be sputtered of the target surrounds a discharge space; placing a substrate on a side of an opening of the space such that the substrate faces an anode disposed so as to close another opening of the space surrounded by the target; supplying a sputtering gas and a fluorine-containing gas into the vessel; and supplying a dc power or a power obtained by superimposing pulses with reversing polarities on the dc power, between the target and the anode, wherein a discharge is induced in the discharge space to sputter the target, thereby forming a fluorine-containing thin film on the substrate.

Thin film production process and optical device

An image information recording apparatus is arranged to record compressed image information within a predetermined section of a recording tape extending from a beginning of the tape, to record non-compressed image information in another section located after the predetermined section, and to record, also within the predetermined section, positional information indicative of a position where the non-compressed image information which corresponds to the compressed image information is recorded on the tape, so that all recorded images are quickly graspable and any of the non-compressed images thus can be quickly extracted. Further, in recording image information of a plurality of kinds, a non-recorded area of a tape-shaped recording medium is divided and a divided recording area thus obtained is allocated to some of the image information of different kinds, so that the tape-shaped recording medium can be efficiently used.

Recording apparatus for recording moving and still signals on different parts of tape-shaped recording medium

In an image processing method and apparatus, image data having multi-value levels for one pixel is input, and the input image data is quantized such that an output area of one pixel is adapted to an output device in which an output area of one pixel changes depending on the position of the pixel. A quantizing process executes an arithmetic operation based on an algorithm of a neural network on the basis of a value obtained by multiplying an output value by a weight corresponding to an area of each pixel. Therefore, even if pixels have different maximum luminances, the different numbers of bits, and different color expression capabilities, an optimum half-tone process can be performed by an algorithm based on a cellular neural network, and a high-quality image can be obtained.

Image processing method and apparatus

Taking into consideration the disadvantage that a large-scale analog neural network cannot be constructed as an LSI and, even if this were possible, the cost would be prohibitive and the network would lack universality, a digital image processor for processing input image data based upon a cellular neural network is provided with a first multiply-and-accumulate arithmetic unit for digitally processing multiplication and accumulation of input image data of a plurality of pixels and input weighting values in a predetermined area, a second multiply-and-accumulate arithmetic unit for digitally processing multiplication and accumulation of output image data of a plurality of pixels and output weighting values in a predetermined area, and a non-linear acting unit for deciding output image data in accordance with results of calculation from the first and second multiply-and-accumulate arithmetic unit and non-linear characteristic parameters. This makes it possible to realize an image processor which excels in universality, ease of control and ease of integration.

There is also provided an image processing apparatus which comprises an input unit for inputting image data, a processing unit for providing a residual image effect to the image data input by the input unit using adjacent image data adjacent to the image data, and a display unit for displaying the image data processed by the processing unit, and in which the display frequency of the display unit is lower than the frequency of the image data input by the input unit.

An image processing apparatus includes an input unit for entering a plurality of color image signals, an image processing unit for subjecting the plurality of entered color image signals to processing based upon an algorithm of a cellular neural network, and a comparison decision unit for deciding output color data based upon results of processing by the image processing unit. Since input multivalued color image data based upon the algorithm of a neural network are converted to output color image data, it is possible to obtain a high-quality output color image that is faithful to the input color image.
