Embodiment Construction

[0017] Certain terms are used throughout the specification and preceding claims to refer to particular elements. Those of ordinary skill in the art should understand that hardware manufacturers may use different terms to refer to the same element. The description and the preceding claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The "comprising" mentioned throughout the specification and the preceding claims is an open-ended term, so it should be interpreted as "including but not limited to". Otherwise, the term "coupled" includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

The invention provides a method and device for performing preview control in an electronic device. The method includes the steps of: obtaining a specific preview image from a camera module of the electronic device, and obtaining a specific focus-related parameter corresponding to the specific preview image; wherein, the specific focus-related parameter is related to the focus control of the camera module; according to the specific adjustment size parameter and specific focus-related parameters, determine specific resizing parameters corresponding to the specific preview image; and perform a resizing operation on the specific preview image according to the specific resizing parameter, so as to control the specific preview image with respect to the plurality of preview images The constant size of the way to display. The method and device for performing preview control in an electronic device proposed by the present invention can improve the overall performance of the electronic device.

Description

technical field [0001] The present invention relates to camera control in portable electronic devices (eg, multifunctional mobile phones), and more particularly to methods for performing preview control in electronic devices and related devices. Background technique [0002] The autofocus process of the camera device changes the size of the captured content with respect to the focus setting. In the existing autofocus process of existing portable electronic devices, in the case of displaying a preview image, since the focus distance (i.e., the distance between the camera lens and the image sensor) changes with the focus setting in response to the autofocus process Change, the size of the captured content changes with the focus setting. As a result, users may feel visually disturbed by gazing at the resized preview frame in the relevant mechanism, which will lead to an unsatisfactory user experience. Contents of the invention [0003] In view of this, the present invention...
