摘要： The electric power consumption by a terminal used for communication of multimedia information is controlled by changing the quality of transmitted information. The terminal is provided with input (101, 102, 106 and 107) through which such information as images and sounds is inputted, channel control sections (123 and 124) which output the input information to channels and receive information from the channels, output (103, 104, 108, 109 and 105) which output the information received from the channels in the form of images, sounds, etc., a codec (110) which is provided between the input and output and the control sections, encodes the input information in one of multiple encoding modes in which electric power is differently consumed, and decodes the information inputted from the channels, and a control section (133) which controls the selection of the encoding mode. This terminal can continue information communication for a required period of time at minimum power consumption at the sacrifice of the quality of transmitted information. Therefore, either the power consumption or quality of information can be adequately selected according to the transmission.

摘要： In a moving image encoding apparatus, an image signal is converted into a digital image signal by an A/D converter and is stored in frame memory 110. In addition, a movement vector detector 300 detects a movement of the output of the frame memory 110. In an orthogonal transformer 130, a difference signal between a present frame image which is stored in the frame memory 110 and a previous frame image which is stored in a variable delay frame memory 210 is supplied, in which the difference signal is converted by orthogonal transformation. The orthogonally transformed transformation signal is quantized into a linear or nonlinear discrete level on the basis of a step width of quantization from a step size controller 600 in a quantizer 140. Then, the quantized data is encoded into a variable length code in a variable length encoder 150. A movement vector detector 300 detects movement of the image by pattern matching processing between the present frame and the previous frame. A movement vector/encoding mode judger 310 generates the movement vector 3 and the encoding mode 4. The variable length code is transmitted to the transmission circuit after adding a movement vector 3 and encoding mode 4. In these operations, a frame rate controller 700 controls the processing rate of each frame image in the entire apparatus. Frame rate controller 700 calculates a total frame skip number S.sub.T which corresponds to the total number of frames that are not transmitted after a frame has been transmitted. The total frame skip number S.sub.T is calculated by selecting a smaller sum of an externally set signal S.sub.min, signal S.sub.M which is calculated from the degree of movement compensation and S.sub.S which is calculated from the degree of quantization, and an externally set signal S.sub.max.

摘要： An electron gun for a television camera tube comprises a cathode for emission of electrons, a first grid disposed subsequently to the cathode and having a first aperture supplied with a positive voltage relative to the cathode, a second grid disposed subsequently to the first grid and having a second aperture supplied with a higher positive voltage than that supplied to the first grid, and an intermediate grid interposed between the first and second grids and having a hole. The intermediate grid forms a divergent electron lens near the first aperture between the first and second grids. An electron beam having passed through the first aperture is once diverged by the divergent electron lens to form a crossover at an axial position of the gun which is remote from the first grid and at which the potential on the beam axis is high, whereby broadening of the width of the velocity distribution of extracted electrons can be suppressed to a minimum and the amount of beam current passing through the second aperture can be increased.

摘要： A motion vector detecting apparatus for detecting motion vectors based on a current frame data and the preceding frame data. In the motion vector detecting apparatus, first and second memories are provided in order to store the current frame data and the preceding frame data. Additionally, a number of first cache memories, a number of second cache memories, a control circuit, and a motion vector calculation circuit are provided. The control circuit selects the input cache memories into which pixel data are to be written, and the output cache memories, from which pixel data are to be read out, from the first and second cache memories, so that the input cache memories and the output cache memories have no redundant cache memory. Pixel data corresponding to the detection image blocks stored in the first memory and pixel data corresponding to the search image blocks stored in the second memory are sequentially written in the selected input cache memories of the first and second cache memories. Simultaneously, the pixel data corresponding to the detection image blocks and the search image blocks are sequentially read out from the selected output cache memories, and are sequentially supplied to the motion vector calculation circuit.

摘要： A camera tube device for use in a television camera comprises an electron gun including a cathode electrode for emission of an electron beam, and first and second grid electrodes respectively having apertures for controlling the diameter of the electron beam. The aperture of the second grid electrode is sufficiently smaller than the aperture of the first grid electrode. The first grid electrode is applied with a positive voltage relative to the cathode electrode and the second grid electrode is applied with a positive voltage relative to the cathode electrode which is higher than that applied to the first grid electrode. The positive voltage applied to the first grid electrode has such a value that forms the electron beam having passed through the aperture of the first grid electrode into a laminar flow beam. As the level of brightness of the object increases, the positive voltage applied to the first grid electrode is decreased to increase the amount of electron beam passing through the aperture of the second grid electrode.
