Abstract: An input of image data is received, and information of width and/or thickness of a recording medium, which receives an image representing the image data to be recorded thereon, is received. Then, a preset pressing pressure value, which is used when the image is recorded on the recording medium, is obtained based on the information of width and/or thickness, and information of image density in the reference area, which is a part of the image data, is obtained. Then, converted image density information is obtained by converting the information of image density in the reference area based on the pressing pressure value and the information of image density, and image data is generated according to the thus obtained converted image density information.

Abstract: An APL detection unit detects the APL for each unit field time period of an input video signal, and a light source control data production unit produces, depending on the results of the APL detection, a light source control signal at a minimum level which can stably drive a light source when the APL is 0% up to a predetermined value A1, a light source control signal at a maximum level which can stably drive the light source when the APL is a predetermined value A2 up to 100%, and a light source control signal which dynamically varies depending on the APL when the APL is between the predetermined value A1 and the predetermined value A2, to drive the light source on the basis of the light source control signal. As a result, it is possible to mitigate the lack of a contrast feeling and the occurrence of a floating blackness, as well as to improve the reliability of the light source.

Abstract: A control means individually turns each switching means on or off so that a current has a waveform which is approximate to a parabolic waveform and is appropriate for focusing current flows in a focusing coil, synchronizing with a horizontal sweep. When the focusing current increases, energy is transferred from the power source to the focusing coil. When the focusing current decreases, energy is returned from the focusing coil to the power source by a flywheel current. Thus, the focusing current is supplied with less consumption.

Abstract: A dynamic focusing device for cathode ray tubes comprising a crosshatch pattern generator for providing a surface of cathode ray tubes with a crosshatch pattern indicating an adjustment point at which focusing control is carried out. The system uses correction data to achieve proper focus at each adjustment point, i.e., the intersection of the vertical and horizontal lines of the crosshatch pattern defined by arbitrarily divided blocks on the surface of the cathode ray tube. The data between adjacent adjustment points is interpolated in the vertical and horizontal directions to supply an output signal providing proper dynamic focus of the cathode ray tube. The disclosed device produces proper focus uniformity and is able to produce a high definition television image on direct-view devices or projection systems which utilize cathode ray tubes.
