    摘要: A phosphor in which water adsorption onto the surface of a blue phosphor is inhibited, luminance degradation and chromaticity shift of the phosphor is decreased, or discharge characteristics thereof is improved, and a plasma display device using the phosphor. In phosphor layers used for plasma display, selectively coating at least the vicinity of the sides of planes of mirror symmetry containing Ba atoms in a blue phosphor with an oxide or a fluorine-containing oxide inhibits water adsorption onto the surface of the blue phosphor, decreases luminance degradation and chromacity shift of a phosphor, or improves discharge characteristics thereof.

    摘要: The present invention is aimed to provide an autofocus device and a correction method of correcting a zoom tracking curve for an intermediate subject distance without increase in storage capacity. A plurality of zoom tracking curves L1(Z) and L2(Z) corresponding to a plurality of different subject distance and correction data &agr;(Z) calculated in advance are stored in a memory 16. A control circuit 10 carries out a predetermined interpolation process using the stored plurality of zoom tracking curves and correction data to calculate a zoom tracking curve L(Z) corrected with respect to a subject distance differing from the plurality of subject distance. Tracking control of focus is carried out according to this calculated zoom tracking curve.

    摘要: An auto focus camera includes a motor drive circuit. This motor drive circuit causes an AF lens to move by a first predetermined amount a time. A micro-computer determines AF evaluation values at respective lens positions. The AF evaluation values thus determined have a mountain-like characteristic form with a focal point as a summit. The micro-computer detects a maximum AF evaluation value and two AF evaluation values smaller than that value, and determines a deviation of a maximum evaluation position corresponding to the maximum AF evaluation value from a focal point. If the deviation is small, the micro-computer takes the maximum evaluation position as an optimal position. On the other hand, if the deviation is large, the micro-computer takes as an optimal position a position deviated by a second predetermined amount from the maximum evaluation position.
