    • There is provided a self-excited switching power supply circuit. A cycle control capacitor is charged with a flyback voltage generated in a feedback winding of a transformer during OFF operation period in which an exciting current does not flow in a primary winding of the transformer. An OFF control capacitor the charging speed of which changes ON operation period is charged with the charging voltage of the cycle control capacitor during the ON operation period in which an exciting current flows in the primary winding. The charging voltage of the cycle control capacitor is changed with a periodic cycle Tc sufficiently longer than an oscillation cycle To to make the oscillation cycle To of continuous oscillating operation variable based on the periodic cycle Tc. As a result, the frequency of a harmonic is distributed.
    • 提供了一种自激式开关电源电路。 在变压器的初级绕组中不流过励磁电流的关闭运行期间,在变压器的反馈绕组中产生回扫电压的循环控制电容器。 在励磁电流在初级绕组中流动的接通运行期间,使周期控制电容器的充电电压对其运行周期的充电速度变化的OFF控制电容器进行充电。 周期控制电容器的充电电压以比振荡周期To足够长的周期性循环Tc而改变,以使得基于周期性周期Tc的连续振荡操作的振荡周期To变化。 结果,谐波的频率分布。

    • An autofocus system is provided that includes a focus-verification image-recapturing processor and a focus-verification image display processor. The focus-verification image-recapturing processor sets ISO sensitivity to a value lower than a predetermined value and increases an exposure value by adjusting at least one of an aperture value and an exposure time to carry out a focus-verification image-recapturing operation under focusing conditions applied in an antecedent autofocus operation when ISO sensitivity that is set in said auto focus operation exceeds the predetermined value. The focus-verification image display processor displays a focus-verification image obtained by the focus-verification image-recapturing operation when the ISO sensitivity that is set in the auto focus operation exceeds the predetermined value.
    • 提供了一种自动对焦系统,其包括聚焦验证图像再捕获处理器和焦点验证图像显示处理器。 焦点验证图像重新获取处理器将ISO感光度设置为低于预定值的值,并且通过调整光圈值和曝光时间中的至少一个来增加曝光值,以在聚焦下执行聚焦验证图像重新捕获操作 当在所述自动聚焦操作中设定的ISO感光度超过预定值时,在先前的自动对焦操作中应用的条件。 当在自动聚焦操作中设置的ISO感光度超过预定值时,焦点验证图像显示处理器显示通过聚焦验证图像重新获取操作获得的聚焦验证图像。
