Problems solved by technology

[0004] However, it is still difficult to realize real bullet-level high-speed photography on current mobile terminals. Since the actual frame rate=1 / (exposure time+data reading time), to achieve a frame rate such as 240FPS, exposure time and data The total time of reading time is about 4.2 milliseconds. Since the data reading time is also included in the total time, and the data reading time needs to be maintained at a stable value, when each frame of data is generated, it is left to the imaging in the mobile terminal The exposure time of the sensor will be lower than the sum time, so a lower exposure time is required to achieve a higher frame rate
[0005] In addition, in scenes with low light brightness, since the exposure time cannot be adjusted, the brightness of the image data acquired by the imaging sensor on the mobile terminal is low, which directly leads to insufficient brightness of the final generated image data, which affects the image quality and seriously affects the use of users. to experience

Embodiment 1

[0062] Such as figure 1 As shown, the implementation process of the processing method in the camera in the embodiment of the present invention includes the following steps:

[0063] Step 101: Determine the frame rate.

[0064] Specifically, the mobile terminal receives the user's frame rate selection operation, and determines the frame rate currently used for shooting according to the frame rate selection operation input by the user. Users can select the frame rate according to the brightness of the current shooting environment. Among them, there may be multiple values ​​of the frame rate that can be selected by the user, such as 240FPS, 120FPS, and 60FPS. The mobile terminal may be a mobile phone, a PDA (Personal Digital Assistant, Personal Digital Assistant), a PAD (Tablet Computer, Portable Android Device) and other terminals with a camera function.

[0065] Step 102: Determine a first exposure time and a second exposure time according to the frame rate, and the first ex...

Embodiment 2

[0096] In order to realize the method of Embodiment 1, the embodiment of the present invention also provides a processing device in imaging, such as figure 2 As shown, the device includes: a first determining module 21, a second determining module 22, a third determining module 23 and a starting module 24; wherein,

[0097] The first determination module 21 is used to determine the frame rate;

[0098] The second determination module 22 is configured to determine a first exposure time and a second exposure time according to the frame rate, the first exposure time being the exposure time of the main camera and the auxiliary camera;

[0099] The third determination module 23 is used to determine the interval time between the auxiliary camera delaying the main camera startup according to the second exposure time;

[0100] The starting module 24 is used to start the main camera to take pictures, delay the interval time, start the auxiliary camera to take pictures, and store the ...

Abstract

The invention discloses a photographing processing method. The photographing processing method comprises the steps of: determining the frame rate; determining the first exposure time and the second exposure time according to the frame rate, wherein the first exposure time is the exposure time of a main camera and an auxiliary camera; according to the second exposure time, determining the intervaltime when the auxiliary camera is delayed and the main camera is started; and, starting the main camera to photograph, delaying the interval time, starting the auxiliary camera to photograph, and respectively storing photographing data obtained by the main camera and the auxiliary camera according to the photographing sequence. The invention further discloses a photographing processing device.

Description

technical field [0001] The present invention relates to the field of imaging technology, in particular to a processing method and device in imaging. Background technique [0002] With the continuous progress and rapid development of imaging technology in the field of mobile terminals, the imaging hardware and software functions of mobile terminals are becoming more and more perfect and powerful, correspondingly producing a variety of interesting imaging applications, high-speed camera is one of them, in the movie We also call it "bullet time" in the scene. High-speed video is to use a high frame rate camera to shoot high-speed moving objects. Due to the high frame rate, a large number of motion details can be captured, and the usual 24FPS (frame / second) is used in the later playback, which visually creates a kind of The effect of slow motion. [0003] At present, mobile terminals can reach 240 frames per second. It is enough to shoot daily sports scenes at this frame rate,...
