Embodiment Construction

[0056] First, the terms involved in the embodiments of this application are explained:

[0057] Field of view (FOV): see Image 6 , in optical instruments, with the lens of the optical instrument as the vertex, the angle formed by the two edges of the maximum range where the image of the subject can pass through the lens is called the field of view. The size of the field of view determines the field of view of the optical instrument, the larger the field of view, the larger the field of view. That is to say, objects within the field of view can be photographed through the lens, and objects outside the field of view cannot be seen. Image 6 Among them, ab is the diameter of the visible range, point c is the center of the visible range, oc is the object distance, and ω is the field of view.

[0058] The target surface size of the image sensor: refers to the size of the photosensitive element in the image sensor.

[0059] Equivalent focal length: Since the size of the photosen...

Abstract

The invention provides a microspur imaging method and a terminal, relates to the technical field of photographing, and can solve the problem that the imaging quality of a photographed object is low when the photographed object is close to an image sensor in the prior art. The terminal comprises a camera module, an input component, an output component and a processor, wherein the camera module comprises a lens, a lens driving device and an image sensor from an object side to an image side; Wherein the lens is used for supporting clear imaging when the distance between a shot object and the image sensor is within a microspur range. And the lens driving device is used for driving the lens to move along the optical axis when the distance between the shot object and the image sensor is within the micro-distance range, and the driving stroke of the lens driving device is related to the latest focusing distance of the terminal. And the processor is used for controlling the lens driving deviceto enable the lens to focus the shot object. And the input part is used for receiving a shooting instruction input by a user, and the shooting instruction is used for shooting a focused picture. Andthe output part is used for outputting the shot picture.

Description

technical field [0001] The present application relates to the technical field of terminal photography, and in particular to a method for macro imaging and a terminal. Background technique [0002] Usually, users can take still photos or record dynamic videos through the camera on the smart terminal. At present, the camera design methods of smart terminals are divided into fixed focus design and zoom design. Wherein, in the fixed-focus design, the focal length of the camera is a definite value, for example, the focal length of the camera may be 27 mm or 30 mm or 54 mm or other values. In a zoom design, the focal length of the camera is adjustable. In general use scenarios, in order to enable the camera to focus at both infinity and short distances from the subject, the focus distance range of the camera is usually above 7cm. [0003] In many application scenarios, users need to take close-up pictures. For example, users want to take pictures of bugs that are very close to ...
