Embodiment 1

[0019] Embodiments of the present invention provide a method for taking pictures, such as figure 1 shown, including:

[0020] 101. Receive an instruction to start taking pictures.

[0021] Specifically, when the user presses the shutter or the user clicks the camera icon on the display screen, the camera device senses the user's operation of pressing the shutter and generates an instruction to start taking pictures.

[0022] 102. Execute the cycle of acquiring time-sharing images.

[0023] It should be noted that the time-sharing image is the final output image after synthesis.

[0024] It should be noted that in the process of acquiring each time-sharing image, it is necessary to determine whether to end the acquisition of this time-sharing image according to the real-time shaking degree of the camera equipment, so as to ensure that each time-sharing image will not be affected by Camera shake caused blurred picture.

[0025] Wherein, the cycle of acquiring time-sharing im...

Embodiment 2

[0047] Embodiments of the present invention provide a method for taking pictures, such as figure 2 shown, including:

[0048] 201. Receive an instruction to start taking pictures.

[0049] Specifically, when the user presses the shutter or the user clicks the camera icon on the display screen, the camera device senses the user's operation of pressing the shutter and generates an instruction to start taking pictures.

[0050] 202. Execute the cycle of acquiring time-sharing images, and determine whether to end the photographing.

[0051] It should be noted that, for the process of executing the cycle of acquiring time-sharing images, reference may be made to step 102, which will not be repeated here.

[0052] Specifically, determining whether to end the photographing may include at least two methods, one is to determine whether the total exposure time reaches a preset value, and the other is to determine whether an instruction to stop photographing is received.

[0053] Whe...

Embodiment 3

[0065] An embodiment of the present invention provides a photographing method. In this embodiment, the photographing device is controlled according to the exposure time to take photographs. Such as image 3 shown, including:

[0066] 301. Receive an instruction to start taking pictures.

[0067] Specifically, when the user presses the shutter or the user clicks the camera icon on the display screen, the camera device senses the user's operation of pressing the shutter and generates an instruction to start taking pictures.

[0068] 302. Obtain exposure time.

[0069] Specifically, the method for obtaining the exposure time may be to calculate the exposure time according to information such as light intensity and aperture setting after the photographing instruction is obtained. The method for calculating the exposure time may refer to any method for determining the exposure time according to the acquired current environment information or hardware information of the photograp...

Abstract

The invention provides a photographing method and equipment, which relate to the field of image processing and are used to reduce the occupancy of system resources on the premise of ensuring the photographing effect. The method comprises: after receiving an instruction to start photographing, executing a cycle of acquiring time-sharing images until the end of photographing; in the case of ending the photographing, controlling the photographing device to end the acquisition of the last time-sharing image; wherein, the cycle of obtaining time-sharing images Including: controlling the camera device to start acquiring time-sharing images; obtaining the current shake parameters of the camera device in real time; continuing to obtain the current shake parameters of the camera device in real time when the current shake parameters are within the allowable shake range; and obtaining the current shake parameters of the camera device in real time; In the case of shaking range, control the photographing device to end the acquisition of this time-sharing image, store the time-sharing image obtained this time (and continue to control the photographing device to start acquiring the next time-sharing image.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a photographing method and equipment. Background technique [0002] When shooting images, in the case of good light conditions, the corresponding exposure time needs to be shortened to avoid whitening of the picture caused by overexposure. On the contrary, in the case of poor light conditions, the exposure time is generally extended to ensure The brightness of the captured image. During the process of shooting an image with a long exposure time, due to reasons such as hand shaking of the photographer, the resulting image will be blurred. [0003] In order to reduce the image blur caused by camera shake when the exposure time is extended, the prior art usually uses an optical anti-shake device in the camera to solve this problem, but the price of the optical anti-shake device used in this solution is A higher value increases the cost of the camera. [0004] In order to reduce co...
