Example Embodiment

[0043] Example one

[0044] figure 1 It is a flowchart of a method for controlling exposure of panoramic photography provided by the first embodiment of the present invention. This embodiment is applicable to the control of exposure when a mobile terminal is used for panoramic photography. The method can be executed by the mobile terminal and specifically includes the following step:

[0045] Step 110: Start panoramic photography.

[0046] The mobile terminal receives the user's instruction to take a panoramic photo, and starts the panoramic photo.

[0047] Step 120: Obtain the actual angular velocity of the current movement of the mobile terminal.

[0048] When using a mobile terminal to take a panoramic photo, photos of various angles are taken by rotating the mobile terminal. When the mobile terminal is moving, the actual angular velocity of the current movement of the mobile terminal is acquired through the angular velocity sensor.

[0049] Preferably, the actual angular velocity o...

Example Embodiment

[0067] Example two

[0068] figure 2 It is a flow chart of a method for controlling exposure of panoramic photography according to the second embodiment of the present invention. It includes the following steps:

[0069] Step 210: When the mobile terminal moves at a preset angular velocity, record the exposure time to ensure that the picture is not blurred.

[0070] When the mobile terminal moves at a preset angular velocity, the exposure time to ensure that the picture is not blurred is recorded through multiple photographs, and the blurriness threshold can also be set to obtain the exposure time when the blurriness is below the blurriness threshold. The exposure time to ensure that the picture is not blurred, that is, the exposure time when the blur degree is below the blur degree threshold.

[0071] Step 220, start panoramic photography.

[0072] Step 230: Obtain the actual angular velocity of the current movement of the mobile terminal.

[0073] Step 240: Adjust the preset exposur...

Example Embodiment

[0084] Example three

[0085] image 3 It is a schematic diagram of a panoramic photographing exposure control device provided in the third embodiment of the present invention. Such as image 3 As shown, the apparatus for panoramic photographing and exposure provided in this embodiment includes: an activation module 310, an acquisition module 320, an adjustment module 330, and a control module 340.

[0086] Among them, the starting module 310 is used to start panoramic photography;

[0087] The obtaining module 320 is used to obtain the actual angular velocity of the current movement of the mobile terminal;

[0088] The adjustment module 330 is configured to adjust the preset exposure time and gain according to the actual angular velocity, the preset angular velocity, and the exposure time for the mobile terminal to ensure that the image is not blurred when the mobile terminal moves at the preset angular velocity;

[0089] The control module 340 is configured to control the exposure ...

Abstract

The invention discloses a control method and device for panoramic photography exposure. The method comprises the following steps: starting panoramic photography; obtaining actual angular speed of current movement of a mobile terminal; according to the actual angular speed, a preset angular speed and the exposure time for guaranteeing an image not to be fuzzy when the mobile terminal moves at the preset angular speed, adjusting preset exposure time and gain; controlling photography exposure according to the adjusted exposure time and gain. The exposure time and the gain are adjusted according to the actual angular speed of the mobile terminal during movement, the higher the actual angular speed is, the shorter the adjusted exposure time is and the larger the adjusted gain is, the definition of the image is guaranteed, and the lower the actual angular speed is, the longer the adjusted exposure time is, the smaller the adjusted gain is and the smaller the image noise point number is, so that a problem of image fuzziness can be solved and noise points can be optimized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of photographing, and in particular, to a method and device for controlling exposure in panoramic photographing. Background technique [0002] Panoramic photography is to use a camera to stitch a group of photos taken from different angles in a 360-degree scene into a picture that includes the entire scene. Most of the current mobile terminals have the function of taking panoramic photos, mainly because the photographer takes mobile phones and other mobile terminals to take photos in various scenes, and then the mobile terminal automatically stitches the photos in various scenes captured into one photo, but, When a mobile terminal such as a mobile phone takes a panoramic photo, it often occurs that the picture is blurred due to a long exposure time. The solution in the prior art is to lock the exposure time at a very small specific value, but this will Photos of many scenes have excess...
