Description
Technical Field

Background
With the continuous development of communication technology, a large number of popular applications of computer devices such as smart phones, tablet computers and notebook computers are developed towards diversification and individuation, and the computer devices are becoming indispensable devices in life and work. Nowadays, electronic devices such as mobile phones and tablet computers are computer devices carried by people in daily life, and shooting devices are usually arranged on the computer devices so that users can shoot things to be recorded at any time. However, when a computer device with photographing and video recording functions performs photographing and video recording, a light source with alternating current power supply is often encountered, because the alternating current has a sinusoidal property, when shutter time settings of the computer device are not matched, a flicker stripe appears on a picture.
Currently, flicker is typically eliminated by controlling the exposure time to be 1/100s or an integer multiple of 1/120 s. However, in order to obtain accurate exposure under the condition that the indoor light source is relatively bright, the exposure time is generally reduced to less than 1/100s, so that the flicker phenomenon of the photographing picture is difficult to eliminate, thereby affecting the photographing effect, and leading to unsatisfactory effect of the photo taken by the user when photographing.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.
The embodiment of the application provides a shooting method, a shooting device, computer equipment and a storage medium. Specifically, the shooting method of the embodiment of the application can be executed by a computer device, wherein the computer device can be a terminal or a server and other devices. The terminal can be a terminal device such as a smart phone, a tablet computer, a notebook computer, a touch screen, a game machine, a personal computer (PC, personal Computer), a personal digital assistant (Personal Digital Assistant, PDA) and the like. The photographing method, apparatus, terminal, and storage medium are described in detail below. The following description of the embodiments is not intended to limit the preferred embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart of a photographing method according to an embodiment of the present application, and the specific flow may be as follows:
101, when detecting that the shooting device is in a working state, acquiring the current exposure time length of the shooting device and the flicker frequency of current ambient light.
In the embodiment of the present application, a light sensing sensor may be provided in the photographing apparatus, and the light sensing sensor is used to detect the flicker frequency of the current ambient light. The photometric sensor is connected to a central processor of the photographing apparatus. When the camera is detected to be started, the camera is determined to be in a working state, and the photosensitive sensor can be started through an instruction, so that the flicker frequency of the current ambient light is detected through the photosensitive sensor.
After determining that the shooting device is in a working state, the shooting device determines exposure time suitable for the current environment light based on the current environment light. Optionally, in the case that the illumination intensity of the current ambient light varies strongly, the photographing device may automatically determine the exposure time period adapted to the current ambient light.
To determine whether the current photographing environment will generate a photographing flicker situation, before the step of "acquiring the flicker frequency of the current ambient light", the method may include:
judging whether the current exposure time length is smaller than a preset threshold value or not;
if yes, the flicker frequency of the current ambient light is obtained.
Optionally, before the step of "obtaining the flicker frequency of the current ambient light", the method may include:
acquiring a light intensity value of current ambient light, and judging whether the shooting equipment shoots indoors or not;
if yes, the flicker frequency of the current ambient light is obtained.
In a specific embodiment, before the step of determining the post-filling exposure time period based on the flicker frequency and the current exposure time period, where the post-filling exposure time period includes a target exposure time period and a target non-exposure time period that are arranged at intervals, and the total time period of the target exposure time period is equal to the current exposure time period, the method may include:
determining whether a shooting flicker condition exists or not based on the current exposure time and the flicker frequency of the current ambient light;
if yes, determining the exposure time after filling based on the flicker frequency and the current exposure time.
Specifically, the flicker frequency of the current ambient light may be 50hz ac frequency or 60hz ac frequency. After determining that the current exposure time is less than the preset threshold value for 10ms, determining how to process the current exposure time according to the alternating current frequency to obtain the filled exposure time. For example, when the flicker frequency of the current ambient light is 50hz, after determining that the current exposure time is less than the preset threshold value for 10ms, the current exposure time may be processed based on the preset time for 10ms to obtain the post-filling exposure time; for another example, when the flicker frequency of the current ambient light is 60hz ac frequency, after determining that the current exposure time period is less than the preset threshold value for 10ms, the current exposure time period may be processed based on the preset time period of 8.33ms to obtain the post-filling exposure time period.
Optionally, the number of divided parts of the current exposure time can be set by itself, and the greater the average number of divided parts of the current exposure time is, the better the flicker eliminating effect is.
102, determining a post-filling exposure time based on the flicker frequency and the current exposure time, wherein the post-filling exposure time comprises a target exposure time period and a target non-exposure time period which are arranged at intervals, and the total time length of the target exposure time period is equal to the current exposure time period.
Specifically, the step of determining a post-filling exposure time period based on the flicker frequency and the current exposure time period, where the post-filling exposure time period includes a target exposure time period and a target non-exposure time period that are arranged at intervals, and a total time period of the target exposure time period is equal to the current exposure time period, and the method may include:
determining a target exposure period based on a preset duration corresponding to the flicker frequency and the current exposure duration;
determining a first designated number of the target exposure periods according to the target exposure period and the current exposure time length;
determining a second specified number of target non-exposure periods according to the first specified number and the preset duration;
a post-fill exposure duration is determined based on the first specified number of target exposure periods and the second specified number of target no-exposure periods.
Specifically, the step of determining a post-filling exposure duration based on the first specified number of target exposure periods and the second specified number of target non-exposure periods may include:
and arranging the first specified number of target exposure time periods and the second specified number of target non-exposure time periods at intervals to generate a post-filling exposure time period, wherein the sum of the first specified number of target exposure time periods and the second specified number of non-exposure time periods is the preset time period.
For example, when the current exposure time of the photographing device in a room is 5ms and the flicker frequency of the current ambient light is 50hz, the exposure time of 5ms is equally divided into 10 parts to obtain a target exposure time period of 0.5ms, and 10 parts of target exposure time periods are uniformly distributed in a time axis of 10ms and are arranged at intervals with 10 parts of target non-exposure time periods with the time period of 0.5ms to obtain a post-filling exposure time period with the total time period of 10 ms.
And 103, controlling the shooting device to shoot based on the post-filling exposure time.
After the post-filling exposure time is determined, the shooting device can be controlled to shoot according to the post-filling exposure time. Specifically, the shutter time of the photographing device may be set based on the post-filling exposure time period, so as to control the photographing device to perform photographing according to the post-filling exposure time period.
In summary, the embodiment of the present application provides a shooting method, where when a shooting device is detected to be in a working state, a current exposure time length of the shooting device and a flicker frequency of current ambient light are obtained, and then a post-filling exposure time length is determined based on the flicker frequency and the current exposure time length, where the post-filling exposure time length includes a target exposure time period and a target non-exposure time period that are arranged at intervals, and a total time length of the target exposure time period is equal to the current exposure time length; and finally, controlling the shooting device to shoot based on the exposure time after filling. The embodiment of the application can effectively eliminate the flicker stripes generated during shooting by adjusting the exposure time, thereby ensuring the shooting imaging quality.
