Abstract

The invention provides a black card control method and an electronic device which uses the method. The black card control method comprises the following steps: the electronic device with the photographing function is provided; the electronic device comprises a photosensitive element, a shutter device, a camera module and a black card device. The photographing element obtains image data, and then the image data is analyzed and calculated so as to obtain luminance contrast data; and the black card device is moved according to the luminance contrast data and oscillating parameters of the black card device are set, and then the shutter device is started; the black card device is oscillated according to the oscillating parameters.

Description

technical field [0001] The present invention relates to a black card control method and its application device, in particular to a black card control method and its application device operated by a processing module of an electronic device, so as to reduce the high contrast of brightness of the scene when taking pictures the following impact. Background technique [0002] With the gradual popularization of digital cameras, taking pictures has become a way for modern people to record life and leave good memories. Under normal circumstances, if you want to take good photos, you will choose to shoot in the direction of the light when lighting or framing, so as to obtain photos with sufficient light and exposure. However, when facing the sun or strong light for backlight shooting, because the sunlight is too strong, it will form a high contrast in brightness with other scenes. If the exposure time is too short, the low-brightness scenes will not be able to show their original a...
