Step S103, the outdoor scene in existing picture and exposure area is synthesized in a pictures.
User has determined behind exposure area, presses shooting push button, and multiple exposing device just synthesizes the outdoor scene 20 in described existing picture 10 and exposure area in a pictures, and described synthetic picture is a multiple-exposure photo.As required, can also return to step S101 using described multiple-exposure photo as existing picture, proceed to take exposure.
In conjunction with referring to Fig. 2, Fig. 3, multiple exposing method the second embodiment of the present invention is proposed, described multiple exposing method comprises the following steps:
Step S201, in the preview interface of finding a view, show the synthetic effect of existing picture and outdoor scene.
Step S202, in the preview interface of finding a view selected at least two exposure areas.
The present embodiment provides at least two exposure area choice boxs 121 in the preview interface of finding a view as shown in Figure 2, each exposure area choice box 121 can be adjusted to suitable position, can also adjust the size and shape of each exposure area choice box 121, as various geometric configuratioies or animals and plants contour shape etc.Final each exposure area choice box 121 limited ranges are each selected exposure area.The quantity of exposure area can preset, and also can in shooting process, set at any time or change.For example, for touch screen multiple exposing device, the long touch screen of pressing ejects the option that increases and reduce exposure area choice box 121, also can drag exposure area choice box 121 and be deleted to screen border.
Step S203, the type of exposure that each exposure area is set and exposure parameter.
Can arrange the type of exposure of each exposure area and exposure parameter.For example the pixel ratio of each exposure area can be set, so that picture synthetic after, it is more real or more empty than the image of the image in other exposure areas or existing picture that image in certain exposure area seems, thereby further expanded the writing space of multiple-exposure.Concrete type of exposure and exposure parameter arrange example and are listed below:
Type of exposure 1: simple superposition
Exposure parameter 1: brilliance control
Illustrate: the picture that directly superposes generally can cause overexposure problem, such as the brightness of photo is originally 100, after two stacks, brightness has just become 200, so directly stack can cause picture excessively bright, the exposure parameter 1 has here been set brilliance control, such as parameter is 0.75, before synthetic, have so the operation of 100*0.75, thereby realize the object of controlling last picture brightness.Under half-light, use the method can improve picture brightness.
Type of exposure 2: brightness stack
Exposure parameter 2: luminance threshold
Illustrate: described luminance threshold represents that the brightness of certain pixel on the second pictures surpasses how many times, can cover the pixel of the same position of the first pictures.When this exposure parameter 2 does not arrange, the brightness that represents pixel on the second pictures can be covered while surpassing the brightness of chapter 1.
Type of exposure 3: dark portion stack
Exposure parameter 3: darkness threshold value
Illustrate: contrary with brightness stack, the less pixel of brightness can cover the higher pixel of brightness.
Type of exposure 4: splicing stack
Exposure parameter 4: emergence scope
The degree that when exposure parameter 4 represents to replace, sprout wings in edge is described: in overlap-add region, the second pictures can replace the pixel of the first pictures.
Type of exposure 5: ratio stack
Exposure parameter 5: pixel ratio
Illustrate: reference exposure Class1 " simple superposition ", but what now control is synthetic ratio, the pixel value that for example first pixel value is 100, the second figure is 200, pixel ratio is 0.3, and final result of calculation is 100*0.3+200*(1-0.3)=170.
Step S204, the outdoor scene in existing picture and each exposure area is synthesized in a pictures.
