    There is a difference. 1. The so-called fill light of the camera is actually a focusing auxiliary light. When shooting in the dark, it is difficult for the camera to focus due to the dark environment, so when the focus auxiliary light is turned on, the cover will be eliminated, and the auxiliary light will illuminate the shooting object to make the camera focus accurately.

    After focusing, the auxiliary light will turn off and will not participate in the fill light. When shooting in the dark, the flash will fire at the moment the shutter is opened, illuminating the subject.

    2. Flash:

    3. Fill light:

    4. LED fill light is the use of LED light-emitting diode to fill the light of the photographed object, LED light is generally used in mobile phones or digital video cameras due to low energy consumption and high brightness, and is used for fill light when the light is not filled. Since the brightness of LED light diodes is much lower than that of real flashes, they can only play the role of "fill light".

    5. Now some mobile phones have used the same flash as the camera, such as Sony Ericsson's K790C, which uses a xenon flash, which is better than the LED fill light, but it cannot be used as a flashlight like LED.

    6. The principle of LED flash: Wuzhi LED does not emit light through the electronic jump inside the atom, but through the wheel cherry to add voltage to both ends of the PN junction of the LED, so that the PN junction itself forms an energy level, and then the electrons jump on this energy level and produce photons to emit light. The service life of qualified LEDs should reach about 100,000 hours at rated power.

    The flash is better, and it's much better, just like a camera, it's much better than the fill light in terms of brightness and range, but there are not many mobile phones that generally have a flash, and even if they do, the effect is not ideal!!

    In general, only mobile phones use LED fill lights, and cameras use flashes. The flash is bright and powerful, but it doesn't last. The fill light is much weaker, but can be used as a continuous illumination.

    There must be a difference, there are thousands of better photographic lights, and the things that come out are not the same.

    There is no difference, and generally formal manufacturers call it "flash", and its role is to fill in the light of the subject.

    1. The so-called fill light of the camera is actually a focusing auxiliary light. When shooting in the dark, it is difficult for the Daqi camera to focus due to the dark environment, and when the focus auxiliary light is turned on, the auxiliary light will illuminate the shooting object and make the camera focus accurately. After focusing, the auxiliary light will turn off and will not participate in the fill light.

    When shooting in the dark, the flash will light up the subject at the moment when the shutter is opened.

The actual phase is standard, i.e., 320*240. Since the CMOS used by mobile phones is interpolated, it is claimed that the number of thousands of phases is not helpful in nature, but only to enlarge the photo. But the phase is still so big, so the bigger it is, the more blurry it is.
