    摘要: A method of displaying a dynamic halftone image on a display panel made of pixels divides each frame of the image into subframes and turns on and off the subframes. The method includes the steps of finding a line of pixels that simultaneously display a specific intensity level in a frame and another specific intensity level in the next frame, counting the number of pixels in the line, selecting corrective pulses, which turn on/off corresponding subframes to enable/disable corresponding intensity levels, according to the counted number and a change in the specific intensity levels between the frames, and adjusting original display signals for the pixels in the line according to the corrective pulses, respectively. The method eliminates halftone disturbance and false color contours from the image even if the moving speed of the image on the display panel is high.

    摘要: A stage apparatus of the present invention includes a plurality of interferometers 14H, 14J, 14R for measuring the displacements of a fine adjustment stage 11 at respective measuring sites, a plurality of actuators 29h, 29j, 29r for independently moving the stage 11, and a mathematical operational conversion unit 43. Deviations .DELTA.H, .DELTA.J and .DELTA.R are derived by a subtracting displacements H, J, R of the stage 11 actually measured by the interferometers from the target displacements HT, JT, RT of the stage 11, and supplied to the mathematical operational conversion unit 43, where the target driven increments .DELTA.h, .DELTA.j, .DELTA.r are derived by a calculation using a predetermined mathematical model (this model is an inverse matrix T.sup.-1, which is the inverse of the matrix T describing the operation for deriving the displacements measured by the interferometers from the displacement produced by the actuators). The rotational speed controllers 39A, 39B, 39C of the actuators are driven by the amounts h, j, r that correspond to the target driven increments .DELTA.h, .DELTA.j, .DELTA.r. This results in a reduced effect of any mechanical interference, so that the positioning of the fine adjustment stage 11 can be quickly achieved with high accuracy.

    摘要: A method of controlling the gray scale of a plasma display device has a forming step of forming a frame for an image by a plurality of subframes each having a different brightness, a setting step of setting the number of sustain emissions of each subframe in an anti-geometrical progression corresponding to the brightness of each subframe, and a displaying step of displaying the image on the plasma display device by a gray scale display having a specific brightness. The number of sustain emissions in each subframe is set individually by the each subframe, and this establishes a linear relation between the gray level and the corresponding brightness Therefore, an enhancement of display quality of the plasma display device can be realized.

    摘要: In a stage-drive controlling device used in a scanning projection exposure apparatus, a targeted speed Iwy is imparted to a speed control system for controlling the speed of a substrate stage, and a targeted speed Irc is concurrently imparted to a speed control system for controlling the speed of a mask stage such that the two stages assume a predetermined positional relationship. A deviation Xrc in the speed of the Speed control system is multiplied by 1/4 (multiplied by the magnification of projection) by a deviation feedback system, and the multiplied value is fed back as a targeted input to the speed control system. For this reason, the following formula holds: Ywy={Kwy/(s+Kwy)}.times.(Yrc/4). If the response of the speed control system side (substrate stage side) is good, even if the speed response of the speed control system side (mask stage side) is poor, the speed ratio between the two stages is kept at 4:1.
