The AF module may include an AF sensor having a plurality of AF pixels and a controller. The controller receives an information regarding the amount of light respectively received by the light receiving elements of one or more of the plurality of AF pixels from the one or more of the plurality of AF pixels. The controller of the AF sensor may be configured to control the operations, e.g., the light exposure timing, of the plurality of AF pixels based on the information received from the AF pixels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Auto focus module capable of in-pixel monitoring of amount of received light photographing apparatus using the same","description":"Disclosed are an auto focus (AF) module and a photographing apparatus employing the same.
