Galaxy S9 for Samsung’s camera using a double diaphragm system was his first smartphone. Set the phone’s camera aperture to F1 in low light conditions. It allowed it to expand to 5 and let in more light in value for slightly blurry edges. The aperture of the camera is F2 for sharper shots in daylight conditions. stayed at 4.
The technology was also included in the Galaxy S10 series, but the company dropped it with the Galaxy S20 series. Now Samsung seems to be working on a dual aperture system for smartphones with triple camera setups.
Samsung has applied for a new patent explaining how motion camera sensors can be used to switch between two lenses with different aperture costs. The patent shows a triple camera setup where each sensor can change its position. In its standard setup, the camera sensors are placed horizontally. However, they can be moved using a gear and rack system. The middle camera moves up and down, while the other two sensors move sideways.
In its alternative setup, the camera sensors are arranged in a triangular arrangement. It sits behind its secondary lenses, which have different apertures compared to the primary lenses. The patent states that the cameras use wider aperture lenses when arranged in a triangular arrangement and narrower aperture lenses when arranged in a horizontal arrangement. Similar to the Galaxy S9’s camera, this system allows the phone’s camera to switch in the middle of different aperture prices depending on the lighting conditions.
While this camera system looks extremely flexible and useful, many moving segments can lead to mechanical failures in the future, especially when subjected to drops and impacts. Moreover, we still do not know if Samsung will actually use this camera system in any of its upcoming smartphones.
