Abstract
The invention discloses a photographing method for an intelligent terminal. The photographing method comprises the following steps: S1: starting a device photographing program; S2: acquiring brightness values in a selected photographing area; S3: acquiring a difference value between a maximum brightness value and a minimum brightness value in the photographing area; S4: judging whether the difference value is greater than a threshold value; and S5: if the difference value is greater than the threshold value, automatically starting an HDR photographing mode; and if the difference value is smaller than or equal to the threshold value, continuing to use a default photographing mode. The photographing method disclosed by the invention can automatically switch to the HDR photographing mode according to a brightness difference in a scene; even though in the scene with the obvious bright-dark difference, the normal display of an image also can be realized; and meanwhile, the photographing method can automatically switch the HDR photographing mode, so the requirement of a non-professional photographing user on photographed image quality is met.
Description
Technical field
The present invention relates to the technical field of intelligent terminal, more particularly to a kind of photographic method of intelligent terminal.
Background technology
The photographing device that intelligent terminal in the market is carried, more using fully automatic exposure mode (AE), i.e., according to quilt
Brightness and the lens focus of body are taken the photograph, a kind of exposure mode of exposure combination (diaphragm shutter) is automatically determined.However, AE exposure skills
Art only one of which exposure value, when shooting the big scene of light and shade gap, such as shooting the portrait that the deep colour of skin and the shallow colour of skin coexist, AE skills
Art is difficult to meet exposure demand.
High energy dynamic range is imaged (HDR) technology, and used as a kind of Image Post-processing Techniques, it being capable of render real well
The gray scale enriched in life, produces effect true to nature.Its implementation is by setting multigroup EV values come to current shooting
Scenery exposes, wherein a photo is several in addition using current light-metering so as to the EV values under normal circumstances for calculating expose
Then it is exposed using the EV values of its EV-n and the EV values of EV+m respectively.Finally multiple pictures are synthesized by certain algorithm,
The local pictures that the scenery of dark place is exposed using high power EV, and the local pictures that the object at bright place is then exposed using low power EV.This
Sample can just cause the scene of whole photo to be all unlikely to too light or too dark.
The present invention combines HDR technologies, proposes a kind of exposure method of new photographing device, in overcoming prior art,
When shooting the big scene of light and shade gap, such as shooting the portrait that the deep colour of skin and the shallow colour of skin coexist, AE technologies are difficult to meet exposure need
The problem asked.
The content of the invention
Novel intelligent terminal photographic method proposed by the present invention, its can zoning picture automatically brightness value, work as judgement
When luminance difference value is more than a certain threshold values, then start HDR exposal models, solve photographed scene light and shade gap in prior art
Greatly, the problem for causing bright or excessively dark image normally to show.
Specifically, the present invention proposes a kind of photographic method of intelligent terminal, comprises the following steps：S1:Starting device is taken pictures
Program；S2:Obtain the brightness value selected in shooting area；S3:Obtain maximum brightness value and minimum brightness in the shooting area
The difference of value；S4:Judge the difference whether more than threshold value；S5:If the difference is more than the threshold value, automatic HDR
Exposal model；If the difference is less than or equal to the threshold value, it is continuing with giving tacit consent to exposal model；S6:Complete to take pictures.
Preferably, database is set in the intelligent terminal, for the brightness value of acquisition and institute in storing step S2
State coordinate value.
Preferably, the shooting area is face identification region.
Preferably, the threshold value is the brightness value for setting in intelligent terminal in advance.
Preferably, the intelligent terminal has data processing module, for calculating the luminance difference in different shooting areas,
And be compared it with the threshold value.
Preferably, the program of taking pictures is the self-contained program of taking pictures of the intelligent terminal.
Preferably, the program of taking pictures is the application program that the operating system based on the intelligent terminal is developed.
Preferably, the intelligent terminal is digital camera, panel computer or smart mobile phone.
Compared with prior art, it is of the invention it is a technical advantage that：
1) present invention is capable of achieving to automatically switch to HDR exposal models, even if in light and shade gap according to luminance difference in scene
Significantly in scene, the normal display of image is also capable of achieving.
2) present invention can independently switch HDR exposal models, meet amateur photography user to shooting the requirement of image quality.
Description of the drawings
Fig. 1 is the flow chart of the photographic method of an intelligent terminal for meeting one embodiment of the present invention.
Specific embodiment
The superiority of the present invention is elaborated below in conjunction with drawings and the specific embodiments.
Refering to Fig. 1, it is the flow chart of the photographic method of an intelligent terminal for meeting one embodiment of the present invention.From figure
In as can be seen that present embodiments provide a kind of photographic method of intelligent terminal, it specifically includes following steps：
S1:Starting device is taken pictures program；User need shoot photo when, can from the shortcut icon of intelligent terminal desktop, or
Button of taking pictures is selected in the quick drop-down menu of person, and starts program of taking pictures.
Preferably, the program of taking pictures can be the self-contained program of taking pictures of the intelligent terminal, or alternatively be based on
The application program of the operating system exploitation of the intelligent terminal.
S2:Obtain the brightness value selected in shooting area；Intelligent terminal is entered after program of taking pictures, and system will automatically obtain use
Photographed scene, the such as brightness value in recognition of face region are chosen in family, and e.g., system can first detect face and obtain its position, and
The data of above-mentioned face location are fed back to intelligent terminal, system obtains the bright of each human face region in scene according to the position data
Angle value Y, and value Y is fed back to into intelligent terminal.
Wherein it is preferred to, database is provided with intelligent terminal in the present embodiment, for obtaining in storing step S2
The brightness value, terminal can automatically by extracting corresponding data in the database during taking pictures.
S3:Obtain the difference of maximum brightness value and minimum luminance value in the shooting area；Intelligent terminal receives above-mentioned anti-
Answer in scene after the brightness value of brightness case, programming count simultaneously calculates the difference of maximum brightness value and minimum luminance value in scene
△Y。
Wherein it is preferred to, the intelligent terminal described in the present embodiment is additionally provided with data processing module, and it can read is clapped
The brightness value taken the photograph in photo, and its mathematical computing engine is relied on, calculate the luminance difference in different shooting areas.
S4:Judge the difference whether more than threshold value；Luminance difference in the scene that intelligent terminal automatically goes out system-computed
Value △ Y is compared with luminance threshold.
Wherein it is preferred to, the threshold value used in the present embodiment be the brightness recognition capability according to human eye and in advance in intelligence
