The main application of the mobile phone is to make a call and send a short message, so that the mobile phone can be carried with the user at ordinary times. In terms of convenience, the mobile phone is significantly higher than the camera.
However, there are some disadvantages of mobile phones compared with cameras that are difficult to overcome: i.e. the mobile phone camera has no loop regulator.
Light and shadow are souls in photography, so the choice of light is never the most important. The camera of the mobile phone is relatively simple, and the aperture size cannot be adjusted. And the aperture is irreplaceable in terms of controlling the light and shadow. At present, the aperture for the mobile phone only has a fixed aperture with a round hole, but the iris type aperture is generally adopted by professional cameras and belongs to a blade type aperture, and the iris type aperture is composed of a plurality of arc-shaped metal sheets which are mutually overlapped. The clutch of the blade can change the size of the central aperture, but the diaphragm is made of metal sheets, and has large volume, thicker diaphragm and high energy consumption. The mobile phone is used as portable palm equipment, and has strict requirements on the whole volume, thickness and power consumption. Therefore, the blade type aperture is not suitable for a mobile phone, and the mobile phone can only use the fixed aperture. However, the fixed aperture is not adjustable in size and has limitations, so that the shooting requirements in the aspects of depth of field adjustment, night scene shooting and the like are not met.
