Abstract: A display device capable of realizing a desired color temperature is provided. Phosphor layers 5a, 5b and 5c, which are excited by ultraviolet radiation produced by discharge and emit red, green and blue visible light, are formed inside a red, green and blue gas discharge tube 1a, 1b, and 1c, respectively. The height Yc of the phosphor layer 5c with respect to a rear support body 20 is higher than the heights Ya and Yb of the phosphor layers 5a and 5b with respect to the rear support member 20, and establishes the relationship Yc>Ya=Yb. Therefore, the distance from the phosphor layer 5c to the opposite discharge surface on a front support body is shorter than those from the phosphor layers 5a and 5b, the visible light emitted from the display device 10 is shifted toward blue, that is, the color temperature increases.

Abstract: A step-down power supply receives an external power supply voltage and supplies power at a reduced voltage from an output node to a load. The power supply also receives a reference voltage and a control signal indicating the whether the load is active or not. The reduced power supply voltage is held equal to the reference voltage by adjustment of the voltage at an internal control node. To prevent fluctuations in the reduced power supply voltage at active-inactive transitions of the load, the power supply includes circuitry for pulling the voltage at the internal control node both up and down, circuitry for leaking current from the output node to ground, circuitry for temporarily raising and lowering the reference voltage, or a capacitor coupling the reference voltage signal line to the control signal line.

Abstract: When the substrate bias voltage Vbb lowers by the pumping operation of the charge pump circuit, a drain-to-source resistance of the N-transistor becomes high. When a first power supply voltage Vcc is set at high value, a drain-to-source current of the N-transistor increases (I+?I1), however the drain-to-source current decreases (I+?I1??I2) by the increase of the drain-to-source current owing to the substrate bias effect so that the increase of the potential of the node N34 caused by the increase of the first power supply voltage VCC is restrained. As a result, a reference level of the substrate bias voltage Vbb does not largely lower than the reference level of the substrate bias voltage. Vbb when the first power supply voltage VCC is in a standard level.

Abstract: First image data including a first pixel value according to the intensity of background light is obtained by means of only exposure. Second image data including a second pixel value according to the intensity of the light reflected or scattered by an object is obtained by so controlling light emission and exposure as to receive part of the reflected or scattered light over the whole exposure period. The part of the reflected or scattered light corresponds to the flat period of emitted pulsed light. Third image data including a third pixel value according to the distance to the object is obtained by so controlling light emission and exposure as to receive the part of the reflected or scattered light for a time according to the distance. The first pixel value is subtracted from each of the second and third pixel values so that the influence of the background light can be excluded.

Abstract: A gas-discharge tube has a glass tube as its main body and a trench is provided in the axial direction of the glass tube on one surface (the surface opposed to the discharge surface) among the external surfaces of the glass tube. An address electrode is placed in the trench. The inner surface of the region of the glass tube where sustain electrodes are placed is formed to have a microscopic unevenness. A secondary electron emission film is formed on this inner surface where the unevenness is formed. In addition, a phosphor support member, whose cross section across the axis is in approximately a C-shape and where a phosphor layer has been formed in advance on the inner surface, is placed inside of the glass tube. Stable discharge characteristics is obtained by eliminating dispersion of the position of an electrode, relative to the gas-discharge tube.

Abstract: An addition image generation module 10 sequentially timewise adds images (input images) of still pictures at individual discrete time points included in a motion picture to be analyzed, thereby generating two kinds of addition images (image A and image B), respectively including images of still pictures at different discrete time points with the images being added at different ratios. Matrix development modules respectively take out pixel groups (first pixel group a(i, j) and second pixel group b(i, j)) located in a predetermined area (for example, in an area having a size of 3×3), from the generated image A and image B. A motion detection module compares the taken out first pixel group a(i, j) and second pixel group b(i, j), to detect a motion component in the motion picture to be analyzed.
