    • A silver halide photographic light-sensitive material is disclosed. The material is comprised of a support having thereon a red-sensitive silver halide photographic emulsion layer comprising a tetramethine melocyanine dye represented by the general formula (I) and a compound represented by the general formula (II) ##STR1## the substituents within these structural formulae are defined within the specification. The material gives improved results with respect to preventing diffuse sensitization. The material also provides a red-sensitive silver halide photographic emulsion in which a decline of spectro-sensitivity in the lapse of dissolution is relatively small and which has a small amount of dye fog.

    • An optical pickup inspection device 3 sends to an actuator drive circuit 16 a command for changing defocus offset amount to set defocus offset amounts, and calculates jitter values for each of the defocus offset amounts based on a reproduction signal from a reproduction signal generation circuit 14. Then, the device 3 determines a quadric approximating curve of jitter values relative to the defocus offset amounts and calculates a correlation coefficient R2 of the quadric approximating curve and measured values. If the correlation coefficient R2 is lower than a threshold value, the setting of defocus offset amounts and the calculation of jitter values are executed once again, otherwise, a defocus offset amount corresponding to a bottom value of jitter in the quadric approximating curve is determined as an optimum value of the defocus offset amount. Thus, a less-error, high-accuracy optimum value of the defocus offset amount can be obtained.
    • 光拾取器检测装置3向致动器驱动电路16发送用于改变散焦偏移量以设定散焦偏移量的命令,并且基于来自再现信号生成电路14的再现信号计算每个散焦偏移量的抖动值。 然后,装置3确定相对于散焦偏移量的抖动值的二次近似曲线,并计算二次逼近曲线和测量值的相关系数R2。 如果相关系数R2低于阈值,则再次执行散焦偏移量的设定和抖动值的计算,否则将对应于二次逼近曲线中的抖动的底部值的散焦偏移量确定为 散焦偏移量的最佳值。 因此,可以获得散焦偏移量的较小误差,高精度的最佳值。
