Problems solved by technology

[0002] The current mobile phone has a camera function, wherein the mobile phone includes a camera device. When the mobile phone is video / photographed by the camera device, due to the different orientations of the lens of the camera device, it will be shifted under the action of gravity, resulting in objects with the same focal length in different postures. out of focus
For example, the user uses the camera device of the mobile phone to take a panoramic photo from the sky to the ground. During the transformation of the scene from the sky to the ground, both the sky and the ground are far-focus objects. When it is the ground, due to gravity, the lens of the camera device will protrude, causing the camera device to take clear photos of the sky, but blurry photos of the ground

Abstract

The invention discloses a photographic device and a focusing compensation method. The photographic device comprises a sensor module, a motor control module, and a motor, wherein the sensor module is used for acquiring change value of acceleration of gravity of the photographic device, the motor control module is connected with the sensor module, and is used for acquiring the change value of acceleration of gravity from the sensor module, and judging whether the change value of the acceleration of gravity is greater than a default threshold value, if yes, the motor control module generates a control signal, the motor is connected with the motor control module, and the motor performs compensatory movement according to the control signal. Through adoption of the method, the photographic device is prevented from losing focus when holding gesture of a user changes, so that the experience effect of the user is improved.

Description

technical field [0001] The invention relates to the technical field of imaging devices, in particular to an imaging device and a focus compensation method thereof. Background technique [0002] The current mobile phone has a camera function, wherein the mobile phone includes a camera device. When the mobile phone is video / photographed by the camera device, due to the different orientations of the lens of the camera device, it will be shifted under the action of gravity, resulting in objects with the same focal length in different postures. Defocus occurs. For example, the user uses the camera device of the mobile phone to take a panoramic photo from the sky to the ground. During the transformation of the scene from the sky to the ground, both the sky and the ground are far-focus objects. When it is the ground, due to gravity, the camera lens of the camera device will protrude, causing the camera device to take clear pictures of the sky and blurred pictures of the ground. ...
