Embodiment Construction

[0081] The embodiments described below by referring to the drawings are exemplary, are only for explaining the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

[0082] see figure 1 and figure 2 , the control method in the embodiment of the present invention is used to control the imaging device to focus in the first focus mode or the second focus mode. The first focus mode is a phase focus mode. The control method includes the following steps:

[0083] S1: acquiring the sensitivity of the image sensor of the imaging device;

[0084] S2: judging whether the sensitivity is greater than or equal to a first threshold; and

[0085] S3: Control the imaging device to focus in the second focus mode when the sensitivity is greater than or equal to the first threshold.

[0086] The control device 100 in the embodiment of the present invention is used to control the imaging device to focus in the first focus mo...

Abstract

The invention discloses a control method. The control method is used to control an imaging device to focus in a first focus mode or a second focus mode. The first focus mode is a phase focus mode. The control method includes the following steps: acquiring the image sensor of the imaging device Sensitivity; judging whether the sensitivity is greater than or equal to a first threshold; and controlling the imaging device to focus in a second focusing mode when the sensitivity is greater than or equal to the first threshold. The invention also discloses a control device and an electronic device. The control method, control device and electronic device in the embodiments of the present invention can enable the imaging device to successfully achieve focusing even in a low-light environment with high sensitivity imaging.

Description

technical field [0001] The invention relates to imaging technology, in particular to a control method, a control device and an electronic device of an imaging device. Background technique [0002] Existing imaging devices may need to use higher ISO for imaging in low-light environments, which may cause large color noise in the image, thereby affecting the realization of phase focusing, and finally causing the imaging device to fail to focus. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention provides a control method and a control device. [0004] The control method in the embodiment of the present invention is used to control the imaging device to focus in the first focus mode or the second focus mode, the first focus mode is a phase focus mode, and the control method includes the following steps: [0005] acquiring the sensitivity of the image sensor o...
