Embodiment Construction

[0020] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Such as figure 1 As shown, the method for controlling ultra-long exposure in the embodiment of the present invention includes:

[0022] Step 101: After receiving the photographing instruction, the terminal determines the current shake offset;

[0023] Step 102: The terminal compares the current jitter offset with a jitter threshold, and selects an exposure mode according to the comparison result;

[0024] Step 103: The terminal...

Abstract

The invention discloses a method and a terminal for controlling overlong exposure, so as to solve the problems that an overlong exposure realization mode in the prior art is fixed, and the flexibility is poor. In the embodiment of the invention, after the terminal receives a photographing instruction, the current jitter offset is determined; the terminal compares the current jitter offset with a jitter threshold, and an exposure mode is selected according to the comparison result; and the terminal carries out exposure treatment according to the selected exposure mode. By adopting the mode of the embodiment of the invention, an applicable overlong exposure mode can be determined according to the current jitter offset of the terminal, the condition of a blurred image caused by adopting an improper exposure method can be effectively avoided, and the flexibility of the overlong exposure realization mode is improved.

Description

technical field [0001] The invention relates to the technical field of digital imaging, in particular to a method and terminal for controlling ultra-long exposure. Background technique [0002] Ultra-long exposure technology refers to the use of a longer exposure time to take photos to make the photos more fluid. Using ultra-long exposure technology can capture the moving trajectory of objects, which can achieve the effect of heavy traffic at night and light painting. Visually More shocking. [0003] Nowadays, some high-end smartphones, cameras and other camera equipment have the function of ultra-long exposure, which has become a major selling point of smart terminals. [0004] There are two ways to realize the ultra-long exposure function: one is the physical ultra-long exposure of the photosensitive device, that is, to allow the light signal to continuously accumulate on the photoreceptor, and finally form an ultra-long exposure image. The advantage of using physical ult...
