Photographing method and device

Abstract

The invention relates to a camera device. The camera device comprises a flasher, a sensing module, a brightness processing module and a brightness compensation module. The flasher is used for laser pre-flashing and main flashing. The sensing module is used for sensing the image information which is fed back after the pre-flashing of the flasher. The brightness processing module is provided with a preset brightness value. The brightness processing module can divide the image information sensed by the sensing module into a high brightness block and a low brightness block, calculate the brightness difference between the average brightness value of the high brightness block and the average brightness value of the low brightness block, compare the brightness difference with the preset brightness value, and judge whether the image information has the depth of field and judge the degree of the depth of field according to the comparison result. If the brightness processing module judges that the image information has the depth of field, the brightness compensation module corrects the main flashing intensity and photosensitivity of a field depth degree correcting flashing device according to the degree of the depth of field judged by the brightness processing module. In addition, the invention also relates to a camera method.

Description

technical field [0001] The invention relates to a photographing system, in particular to a photographing device and a photographing method thereof. Background technique [0002] Today, with the vigorous development of the camera industry, it is not easy for ordinary non-professional photographers to take an ideal photo in a scene with depth of field, especially at night. Usually, in the environment where flashes are required, Cameras use the feedback brightness after the pre-flash to determine the intensity of the main flash. Therefore, when the subject is close to the camera and the background has depth of field, the background of the photo will usually become very dark, making the brightness of the overall photo unbalanced, resulting in overall The photo looks rather awkward. [0003] In addition, in order to increase the brightness of the background, generally, the mechanism of slow flash is used to increase the brightness of the background by increasing the exposure tim...

[0002] Today, with the vigorous development of the camera industry, it is not easy for ordinary non-professional photographers to take an ideal photo in a scene with depth of field, especially at night.

Therefore, when the subject is close to the camera and the background has depth of field, the background of the photo will usually become very dark, making the brightness of the overall photo unbalanced, resulting in overall The photo looks rather awkward

[0003] In addition, in order to increase the brightness of the background, generally, the mechanism of slow flash is used to increase the brightness of the background by increasing the exposure time, but while increasing the exposure time, in order to avoid shaking, the photographer must keep the camera still and the subject must also keep still , which has brought a lot of trouble to non-professional photographers
