Problems solved by technology

[0003] The focus of the lens can realize the clear imaging of the object, but it will reduce the sampling ability of the shooting equipment to the signal, especially the high-frequency signal, which will lead to the blurred image and the problem of poor resolution of the shooting equipment.

Embodiment 2

[0067] Figure 4 The focusing device based on the image sensor provided by Embodiment 2 of the present invention is shown, and for the convenience of description, only the parts related to the present invention are shown.

[0068] Such as Figure 4 As shown, the device includes:

[0069] The first focusing module 4 is configured to control the movement of the lens to focus for the first time after receiving the shooting request information.

[0070] In this embodiment, the first focusing module 4 includes:

[0071] The image acquisition unit 41 is used to capture images through the photosensitive components of the lens during the process of controlling the movement of the lens;

[0072] The calculation unit 42 is used to calculate the definition of the captured image, and use the position with the highest definition as the focus position of the lens;

[0073] The focus unit 43 is configured to move the lens to the focus position to achieve the first focus.

[0074] The se...

Abstract

The invention belongs to the technical field of digital photography, and provides a focusing method and device based on an image sensor. The method includes the steps of controlling a camera lens to move to conduct first focusing after shooting request information is received and controlling the image sensor to move to conduct second focusing through a micromotor mechanism after first focusing is completed. Thus, second focusing and sampling is achieved through shooting equipment in the shooting process, the problem that existing shooting equipment is low in high-frequency signal resolution is solved, and the resolution ratio of shot pictures is improved.

Description

technical field [0001] The invention belongs to the technical field of digital photography, and in particular relates to an image sensor-based focusing method and device. Background technique [0002] At present, the focus system of the shooting equipment generally realizes the focus during shooting by moving the lens, so as to solve the problem of blurred images of objects on the surface of the image sensor. [0003] Lens focusing can achieve clear imaging of objects, but it will reduce the sampling ability of the shooting equipment for signals, especially high-frequency signals, resulting in blurred images and poor resolution of the shooting equipment. Contents of the invention [0004] The purpose of the present invention is to provide a focusing method and device based on an image sensor, so as to improve the resolution of a photographing device and improve the quality of photographed photos. [0005] The present invention is achieved in this way, a focusing method ba...
