Abstract:
1. An image capturing apparatus, comprising: an optical system including an aperture; a first driving unit configured to drive the optical system; an image sensor configured to generate an image signal by photoelectric conversion of light incident from the optical system; a second driving unit configured to drive the image sensor; a detecting unit configured to detect a luminance level of the image signal; a first setting unit configured to set a first mode in which motion images are not recorded or a second mode in which motion images are recorded; and a control unit configured to control the second driving unit to read out an image signal from the image sensor at a first frame rate in a case where the first setting unit sets the first mode or at a second frame rate higher than the first frame rate in a case where the first setting unit sets the second mode, wherein, in a case where the first setting unit sets the first mode, the control unit controls the second driving unit to drive the image sensor so that an exposure time of the image sensor is shorter than or equal to a time corresponding to a reciprocal of the second frame rate, and controls the first driving unit to drive the aperture so that the luminance level detected by the detecting unit is at a predetermined level.
