Today, OFILM announced that it has released a variable aperture camera module. By adding a variable aperture motor to the front of the Lens, the single lens can be changed from F1.4 → F2.0 → F2.8 → F4 .0 Different apertures can be adjusted, so that the module can realize the physical adjustment of the aperture from the hardware, and is no longer limited to the change of the aperture through software algorithms.
Oufeiguang said that the so-called camera aperture refers to the size of the aperture that allows light to enter the sensor. Under the condition that the shutter remains unchanged, the larger the aperture, the more light enters, and the picture is brighter; the smaller the aperture, the darker the picture.
According to reports, the O-Film variable aperture camera module uses large-size photosensitive components and a large aperture lens of F1.4. At the same time, an iris motor is added to the outer surface of the Lens, and the iris motor drives the opening and closing of 6 blades. , so that the module can realize multi-step adjustment of aperture from F1.4 (4.0mm)→ F2.0 (2.9mm)→ F2.8 (2.05mm)→ F4.0 (1.44mm), and each aperture can be adjusted between Fast switching within 20ms. In addition, the module has a full-stroke closed-loop control of the aperture from F1.4 → F4.0, which can realize the switching of any aperture of a single module through software optimization.
OFILM pointed out that by introducing variable aperture technology, the OFILM variable aperture camera module can automatically switch the aperture size and control the amount of light entering, so that the mobile phone only uses a single camera module without the assistance of other lenses. It can precisely match bright and dark scenes under complex lighting conditions, and can easily switch between background blur at large aperture and sharp depth of field at small aperture.
In places with strong light, you can reduce the aperture to bring a clearer picture; while shooting in low light or at night, increase the aperture to get more exposure to reduce noise in the picture. That is, using different apertures in different light and dark scenes can take better-looking photos. In addition, you can easily switch between large and small apertures depending on the subject. A large aperture can blur the background, make people more prominent, and also cause a shallow depth of field. When shooting landscapes, a small aperture may be a better choice.
