摘要： A direct color thermal recording method records full-color images on a thermosensitive color recording medium having at least three laminated thermosensitive recording layers which are developed in three colors. The optical recording is performed in at least the uppermost thermosensitive recording layer by being exposed to ultraviolet rays of a wavelength range specific to the individual recording layer to be recorded while controlling the intensity of rays according to desired color densities of pixels to be recorded in the corresponding layer. Thereafter, thermal recording is performed in a lower recording layer by applying heat energy to the color recording medium. The amount of heat energy is controlled so as to record pixels at the desired color densities in the lower recording layer, and also the heat energy is used to develop colors in at least an upper recording layer after having been subjected to optical recording.

摘要： A motion compensated prediction interframe coding system which first measures characteristics regarding the fineness of a pattern or texture of a picture, which is represented by an input television signal and is divided into a group of continuous blocks each quantized by using a quantization step size, and changes the quantization step size into a smaller one if quantizes a block having a picture pattern or texture finer than patterns of the other blocks. Thereby, an amount of generated codes can be limited but a motion compensated prediction frame coding operation can be performed without degrading the fineness of the texture of the original input picture.

摘要： A moving image signal encoding apparatus includes: a frame decimating circuit for extracting encoded frames from an input moving image signal at specified intervals; a frame interpolating circuit for obtaining an interpolated frame between the encoded frames, and a circuit for obtaining an error formed by frame interpolation. A moving image signal decoding apparatus includes: a receiving circuit for extracting a frame code from an inputted signal; a frame decoding circuit for decoding the frame code to obtain a reproduced frame, and a frame interpolating circuit for obtaining an interpolated frame between the reproduced frames. By transmitting an error of the interpolated frame from the encoding apparatus to the decoding apparatus and correcting the error of the interpolated frame with the decoding apparatus, the error of the interpolated frame is eliminated. Alternatively, depending on the value of the error of the interpolated frame obtained with the encoding apparatus, a circuit determines the operation mode as to whether the frame interpolating circuit of the decoder carries out frame interpolation or preceding value holding and sends a flag to show the operation mode to the decoder, so that improvement occurs when the error of the interpolated frame is large.

摘要： A zoom lens system in which an angle of view is automatically varied according to camera-to-subject distances so as to be able to provide on a photographing screen a subject which is always constant in size. In the zoom lens system, a focus lens is stopped at a given position and, in this condition, a magnification varying lens and a compensator lens are driven to thereby achieve a focusing operation. In this operation, the angle of view is automatically varied according to the camera-to-subject distances, so that the size of the subject can be always constant with respect to the photographing screen regardless of the camera-to-subject distances. As a result of this, according to the invention, there is eliminated the need for provision of a data table memory for performing an automatic zooming operation, and exclusive and complicated control device and position detection device.

摘要： An image forming apparatus includes an image carrier that carries a toner image; a transfer member that forms a transfer nip between the transfer member and the image carrier; and a power supply capable of outputting a superimposed transfer bias in which an alternating current component is superimposed onto a direct current component. The toner image on the image carrier is transferred onto a recording medium in the transfer nip by the superimposed transfer bias or a direct current bias consisting of the direct current component output by the power supply. The apparatus also includes a controller that controls the power supply so that an output target value of the direct current component when the direct current component rises up is larger than an output target value of the direct current component when the toner image is transferred onto the recording medium.

摘要： An image forming apparatus includes an image bearer; a toner image forming unit, a transfer unit, a detector, and a controller. The toner image forming unit forms a plurality of types of density detection patterns on the surface of the image bearer in mutually-different positions in a surface-movement direction of the image bearer. The density detection patterns have mutually-different lengths in a direction orthogonal to the surface-movement direction of the image bearer. The transfer unit transfers the density detection patterns onto the surface of the transfer member. The detector detects image densities of the density detection patterns transferred on the surface of the transfer member. The controller calculates an image density difference between the density detection patterns on a basis of a detection result obtained by the detector, and corrects a transfer bias for transferring a toner image on a basis of a value of the image density difference.
