Embodiment Construction

[0031] refer to figure 1 Shown is a functional block diagram of the electronic device 100 in a preferred embodiment of the present invention. The electronic device can be a mobile phone, a tablet computer, a personal digital assistant, and the like.

[0032] The electronic device 100 includes a lens module 10 , an image sensor 20 , a focusing module 30 , a processor 40 and a memory 50 . The lens module 10 , image sensor 20 , focus module 30 and memory 50 are all connected to the processor 40 .

[0033] In this preferred embodiment, the lens module 10 includes a standard lens 11 , a telephoto lens 13 and a macro lens 12 . The standard lens 11 is a general lens device for general distance shooting. The telephoto lens 13 and the macro lens 12 are used for telephoto and macro photography respectively. The angle of view of the telephoto lens 13 is narrower than that of the standard lens 11 .

[0034] The image sensor 20 is used to capture the image of the subject through the a...

Abstract

The invention discloses an electronic device and a lens switching method thereof. The electronic device comprises a lens module, an image sensor, a focus module and a processor; the lens module comprises a standard lens, a micro lens and a telephoto lens; the image sensor is used to obtain the picture of a shooting target through the multiple lenses mentioned above; the focus module is used to control the multiple lenses mentioned above to focus the shooting target automatically; and the processor is used to select the standard lens as the current lens, obtain a corresponding first focus distance at a first time, obtain a corresponding second focus distance at a second time, and confirm whether or not to switch the current lens to the micro lens or the telephoto lens according to the sizerelationship between the second focus distance and the first focus distance, wherein the second time is later than the first time.

Description

technical field [0001] The invention relates to an electronic device and a lens switching method thereof, in particular to an electronic device capable of automatically switching macro and telephoto lenses and a lens switching method thereof. Background technique [0002] Electronic devices such as mobile phones have camera modules for shooting, but traditional camera modules only have a single lens. For the focusing during shooting, especially when switching to macro objects, the focusing speed is slow and the accuracy is not high. hinders shooting. Contents of the invention [0003] In view of the above problems, it is necessary to provide an electronic device capable of automatically switching macro and telephoto lenses. [0004] In addition, it is necessary to provide a lens switching method corresponding to the above-mentioned electronic device. [0005] An electronic device comprising: [0006] A lens module, the lens module includes a standard lens, a macro lens ...
