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

Abstract

The invention relates to a flash control method of a digital camera. Firstly, the corresponding index value of each sensitivity value is determined. Then, corresponding to the sensitivity values, corresponding main flash intensities are respectively obtained, so that the target luminances achieved after exposure are all the same, thereby establishing and obtaining an energy table. In addition, for each distance, a preset pre-flash intensity is emitted to obtain a corresponding pre-flash brightness value. For each distance, according to the maximum main flash intensity and the energy table, the corresponding main flash index value is obtained, so that the target brightness after exposure is the same, and a pre-flash table is established to obtain. When shooting, the corresponding main flash intensity can be obtained according to the pre-flash brightness value and the pre-flash 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...
