Problems solved by technology

Current photography devices generally have a preview function, users can browse the photos just taken, if the effect is not good, they can delete the photo and take a new photo
However, due to the limited size of the display screen of the photography device, the full-screen preview photo sometimes cannot clearly express the details of the face
When you need to preview on the photography device, you can use the corresponding control button to partially enlarge the photo, but the preview speed is very slow, and when the zoom is too large, the photo will be blurred, making it impossible to quickly and clearly see the details of the face

Abstract

The invention relates to a photographic device comprising a display screen and a processor. The processor comprises a human face detection module, a selection module, a judging module and a processing module, wherein, the human face detection module is used for detecting whether human faces exist in an image or not, and further detecting the number of human faces in the image if human faces exist; the selection module is used for selecting the image of a minimum area covering all the human faces; the judging module is used for judging whether the pixel of the image within the minimum area is larger than the resolution of the display screen or not; if true, the processing module can calculate the image range of the magnified image within the minimum area according to the pixel of the image within the minimum area and the resolution of the display screen, and then, the processing module can further magnify the image within the minimum area according to the image range of the magnified image. Additionally, the invention further relates to a photographic method using the photographic device.

Description

technical field [0001] The invention relates to a photographing technology, in particular to a photographing device and a photographing method thereof. Background technique [0002] With the continuous development of the electronic industry, the application of photographic devices such as digital cameras has become very common. In daily life, people often take photos of people, and most people are non-professional photographers, so it is not easy to take an ideal photo of people. The effect of shooting photos of people mainly depends on whether the faces of the people are clear. Present photography device generally all has the function of previewing, and the user can browse the picture just taken out, if the effect is not good, can delete this picture and take again. However, due to the limited size of the display screen of the photography device, the full-screen preview photo sometimes cannot clearly express the details of the face. When you need to preview on the photog...
