The present invention provides an electric apparatus including an image sensor that starts to accumulate electric charges at different timings in different regions, and an optical filter that can be changed between a first concentration and a second concentration higher than the first concentration. The apparatus includes a first mode of executing a global shutter function so as to start exposure for each pixel included in a predetermined region of the image sensor at substantially the same timing, and a second mode of starting exposure for the respective pixels of the image sensor at different timings. A change in a pixel count of image data read out from the image sensor in accordance with information concerning an exposure time set by a user is larger in the first mode than in the second mode.
