Embodiment Construction

[0018] In the following, a method for night shooting of a mobile phone based on imu information of the present invention will be described in detail in combination with specific embodiments.

[0019] Mobile devices with night shooting functions such as figure 1 As shown, a gyroscope is installed on the mobile phone, and each time the mobile phone takes a photo, the gyroscope will output the angle information of the current mobile phone movement, that is, the imu (inertial measurement unit) information. When shooting at night, the mobile phone continuously shoots 5 images of the same target {A i |i=1,...,5}, at the same time, the gyroscope outputs the imu information of each image. The night shooting method proposed by the present invention uses imu information to correct each image, and then fuses all the corrected images to obtain a high-quality night shooting image.

[0020] The present invention uses IMU information to correct each image to obtain five new source images {...

Abstract

The invention provides a mobile phone night-shot method based on imu information. A gyroscope is installed on the mobile phone; every time the mobile phone takes a photo, the gyroscope outputs angle information of current mobile phone motion, namely imu information. In case of night shot, the mobile phone continuously takes five images {Ai, i=1,...,5} for the same target and the gyroscope outputs the imu information of each image at the same time. According to the night-shot method provided by the invention, imu information is respectively used to correct each image, and all corrected images are fused to obtain a high-quality night-shot image. A device needed for the method provided by the invention is simple in requirement, is relatively low in cost, is not great in algorithm calculation complexity, is capable of better realizing the night-shot function of the mobile phone, and has a high practical value.

Description

technical field [0001] The invention relates to the field of image processing and the technical field of gyroscope image stabilization, in particular to a mobile phone night shooting method based on IMU information. Background technique [0002] In recent years, with the continuous development of camera technology, the camera function of mobile phones has become more and more powerful, and has gradually replaced cameras as the mainstream product for people's daily photos. Camera mobile phones bring a lot of convenience to people's life, but along with the continuous upgrading of mobile phones, especially camera phones with 8 megapixels or even 10 million pixels begin to emerge, people's requirements for mobile phone camera functions are also constantly improving. Only taking high-quality and stable images in normal environments such as daytime can no longer meet the requirements of consumers. People are increasingly pursuing the night shooting function, hoping that they can ...
