Problems solved by technology
However, when the internal or external hardware of the flash of a traditional camera is replaced (such as replacing the capacitor in the flash or the cover of the flash), or even because the flash is old, the accuracy or stability will often be reduced.
[0004] This shows that the above-mentioned existing digital camera flash control method obviously still has inconvenience and defects in method and use, and needs to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general method has no suitable method to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve

The invention relates to a flash control method of a digital camera. The method is characterized by: firstly, determining corresponding indexes of each sensitivity value; then, respectively acquiring corresponding main flash intensities according to the sensitivity values so that reached object brightness after exposure is the same and a energy meter can be established; in addition, emitting a preset preflashing intensity according to each distance so as to obtain a corresponding preflashing brightness value; acquiring the main flash index according to the each distance, the greatest main flash intensity and the energy meter so that the reached object brightness after exposure is the same and a preflashing table can be established. During shooting, the corresponding main flash intensity can be acquired according to the preflashing brightness value and the preflashing table.
Description
technical field [0001] The invention relates to a digital camera, in particular to a flash control method of the digital camera. Background technique [0002] A flash is an essential device for most cameras to illuminate the subject. It is generally used in darker scenes, or to change the quality of light. Flash can be built-in or external. [0003] Although traditional digital cameras have various mechanisms to control the lighting of the flash and the size of the control intensity. However, when the internal or external hardware of the flash of a traditional camera is replaced (such as replacing the capacitor in the flash or the cover of the flash), or even because the flash is old, the accuracy or stability will often be reduced. [0004] It can be seen that the above-mentioned existing digital camera flash control method obviously still has inconvenience and defects in method and use, and needs to be further improved urgently. In order to solve the above-mentioned pr...
