    • The photometric sensor of the present invention includes a plurality of photoelectric conversion elements which accumulate electric charge according to the intensity of the light which is incident upon them; a CCD shift register, comprising a plurality of CCD (Charge Coupled Device) elements which correspond respectively to the plurality of photoelectric conversion elements, and at least one relay CCD element which does not correspond to any one of the photoelectric conversion elements, and which reads in the accumulated electric charges from the plurality of photoelectric conversion elements to the plurality of CCD elements and transmits them via the relay CCD element; a charge to voltage conversion circuit which converts the accumulated electric charges transmitted from the CCD shift register into photometric signals and outputs them in order; and a timing signal generation circuit which, when the photometric signals from the charge to voltage conversion circuit originating from the plurality of photoelectric conversion elements are output, outputs in synchronism with this output a timing signal, and, when a signal from the charge to voltage conversion circuit originating from the relay CCD element is output, does not output the timing signal in synchronism with this output.

    • An apparatus for performing photometry on a photographic subject image divided into plural regions, which eliminates the negative effects on photometry caused by an illumination source which provides auxiliary lighting. The illumination source for providing auxiliary lighting illuminates a portion of the photographic subject. When it is detected that photometry is being performed, illumination by the illumination source may be inhibited such that the brightness of the subject does not suddenly change, thereby adversely effecting photometry. Conversely, when the commencement of the action of the illumination source is detected, photometry may be inhibited such that the change in brightness due to the illumination source has no effect on the photometry. When a portion of the photographic subject has been illuminated by the illumination source during photometry this situation is detected, and the photometric result is corrected to compensate for the effect of the illumination source on photometry.
    • 一种用于对分成多个区域的摄影对象图像进行测光的装置,其消除了由提供辅助照明的照明源引起的对光度测量的负面影响。 用于提供辅助照明的照明源照亮被摄体的一部分。 当检测到正在进行测光时,可以抑制照明源的照明,使得被摄体的亮度不会突然变化,从而不利地进行测光。 相反,当检测到照明源的动作开始时,可​​以抑制测光,使得由于照明源引起的亮度变化对测光没有影响。 当在测光期间拍摄对象的一部分被照明源照亮时,该情况被检测到,并且校正光度结果被校正以补偿照度源对测光的影响。
