Embodiment 1

[0025] figure 1 A flowchart of a flash-based photographing method provided by the first embodiment of the present invention is shown, and the details are as follows:

[0026] In step S11, when entering the flash photography mode, it is determined whether the photography button has been pressed.

[0027] In this step, judging whether the camera button is pressed can be determined by judging whether the key value of the camera button is marked as "pressed". When the value is 0, it indicates that the photographing button is not pressed; when the value of the photographing button is detected as 1, it is determined that the photographing button has been pressed.

[0028] Preferably, before the step of judging whether the photographing button has been pressed, the following steps are included:

[0029] Determine whether the current mode is the camera mode.

[0030] When the current mode is the camera mode, determine whether to enable the flash photo mode, and if so, enter the fla...

Embodiment 2

[0052] figure 2 A structural diagram of a flash-based photographing device provided by the second embodiment of the present invention is shown. For convenience of description, only the parts related to the embodiment of the present invention are shown.

[0053] The flash-based photographing device includes: a photographing button state determination unit 21 , a camera exposure opening unit 22 , a flash opening unit 23 , a flash closing unit 24 , and a photo output unit 25 .

[0054] The photographing button state judging unit 21 is used for judging whether the photographing button has been pressed when entering the flash photographing mode.

[0055] Wherein, to determine whether the photographing button is pressed, it can be determined by judging whether the key value of the photographing button is marked as "pressed".

[0056] Preferably, the device includes:

[0057] The camera mode state determination unit is used to determine whether the current mode is the camera mode....

Abstract

The invention is applicable to the field of image exposure control and provides a photographing method and device based on a flash lamp. The method comprises the steps that in a flash lamp photographing pattern, whether a photographing key is pressed or not is judged; when the photographing key is pressed, exposures of a camera are opened line by line; after the exposures of the camera are all opened, the flash lamp is turned on; when the set flash time corresponding to the current of the flash lamp is up, the flash lamp is turned off; a photo is output. By means of the photographing method and device based on the flash lamp, the photo can be exposed more uniformly, and therefore the quality of the photo is improved.

Description

technical field [0001] The invention belongs to the field of image exposure control, and in particular relates to a flash-based photographing method and device. Background technique [0002] At present, electronic devices (such as smart phones, cameras, etc.) have more and more functions. For example, in addition to the call function, the smart phone also has the function of taking pictures, and in order to clearly capture the scene in the dark environment, the smart phone is also equipped with a flash. . [0003] However, when a user uses an existing electronic device to take a selfie, since the distance between the user and the electronic device is usually only about 40CM, if the brightness of the flash is too high, the user's expression is likely to be stiff during the process of taking a photo, which makes the photo taken. Not ideal, and the flash is too bright and can seriously hurt the user's eyes; but if the flash is not bright enough, the photos taken will be too da...
