Problems solved by technology

[0005] Since the microlens array is expensive, adding a microlens array between the lens and the image sensor will increase the manufacturing cost of the camera device
In addition, increasing the microlens array will also increase the volume of the camera device, which is inconvenient for users to use and carry.

Embodiment 1

[0078] Embodiment 1 of the present invention provides a method for taking pictures, such as figure 2 As shown, the method includes:

[0079] Step S101, acquiring a photographing instruction.

[0080] The user can activate the device physically or virtually, so that the photographing device acquires a photographing instruction. Wherein, taking a picture is also called taking a picture, which is a process of recording and saving an image of an object using a device with a picture taking function. The photographing instruction is an instruction for controlling the photographing device to record the image of the object.

[0081] Step S102, moving the lens according to the photographing instruction.

[0082] After obtaining the photographing instruction, the lens in the photographing device will move according to the preset route. The method of controlling the movement of the lens by a motor is taken as an example to illustrate below. The motor uses the Lorentz force generate...

Embodiment 2

[0109] Such as Figure 7 As shown, the embodiment of the present invention provides a terminal capable of taking pictures, including a starting device 51 , a control processor 52 , a mobile device 53 , a lens 54 , an image sensing device 55 and an image processor 56 . It should be understood that the terminal in this embodiment of the present invention may include Figure 7 more or fewer parts than those shown in the Figure 7 It is an illustrative description for introducing the embodiment of the present invention.

[0110] The starting device 51 is configured to obtain a photographing instruction and transmit the photographing instruction to the control processor. The starting device may be a physical button, a virtual button on the touch screen, or a voice control device. The embodiment of the present invention does not limit the specific structure of the starting device.

[0111]The control processor 52 is configured to control the mobile device 53 and the image sensin...

Embodiment 3

[0118] Such as Figure 8 As shown, the embodiment of the present invention provides a control device capable of controlling photographing, including a photographing instruction receiving unit 61, a movement control unit 62, an image sensing device control unit 63, and an image processor control unit 64, wherein:

[0119] The photographing instruction receiving unit 61 is configured to obtain a photographing instruction of a user. The photographing instruction can be issued by the user through a physical key, a virtual key on the touch screen or a voice control device. The embodiment of the present invention does not limit the specific structure of the starting device.

[0120] The movement control unit 62 is configured to control the mobile device to move the lens 54 according to the photographing instruction. Specifically, the mobile control unit can control the mobile device, so that the lens moves in a preset manner under the control of the mobile device. The relevant dr...

Abstract

The embodiment of the invention provides a photographing method and device. On the premise of not increasing the hardware cost and the device size, image data of an object in a field depth range having different focuses can be recorded by photographing for one time; loss of image details of the object in a fixed single focus can be avoided; and thus, users can see more comprehensive image data. The photographing method disclosed by the invention comprises the following steps: obtaining a photographing instruction; moving a lens according to the photographing instruction; obtaining image data for at least two times in the moving process of the lens so as to obtain at least two image data; and generating an image file according to the at least two image data.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a photographing method and device. Background technique [0002] In photographic technology, such as Figure 1A As shown, when light enters the lens, the lens gathers the light at one point and spreads it out in a cone shape. This point where all the rays gather is called focus 1. When taking a picture, if the object 1 is imaged at the focal point 1, the image of the object obtained through the lens is clear. Around focus 1, the light starts to gather and spread. For example, the images of objects 2 and 3 at the front and back of object 1 gradually become blurred, forming an enlarged circle respectively, and this circle is called a circle of confusion. In reality, if the diameter δ of the circle of confusion is smaller than the discrimination ability of the human eye, the blur generated by the actual imaging within a certain range cannot be recognized, that is, the imaging of t...
