The invention discloses a control method for controlling an imaging device to collect scene data. The control method includes the following steps: processing the scene data to identify whether there is a portrait in the scene; processing the scene data to identify the portrait area when there is a portrait; judging whether the portrait area is exposed Insufficient; when the portrait area is underexposed, perform separate photometry on the portrait area to obtain corrected photometric data; and control the imaging device to collect a first scene main image according to the corrected photometric data, and the scene data includes the first scene main image . The invention also discloses a control device and an electronic device. The control method, control device, and electronic device in the embodiments of the present invention acquire the portrait area based on the depth information, and separately measure and correct the portrait area, which can avoid the problem of dark portraits in images captured under backlight or backlight environments, Improve the quality of captured images.
