The contrast of three fringe regions is named as the 3rd contrast.Further, projected image and the contrast of projection imaging image its
It is the same in fact, i.e. as the second contrast is with the 3rd contrast.
Further, based on image to be projected, in the specific implementation process that a projected image is projected on a perspective plane, also
With following implementation process：
First, based on image to be projected, electronic equipment is adjusted to the second projection mode from the first projection mode.Then,
Under the second projection mode, projection lenses image on the projection surface, to form perspective plane image on the projection surface.
And before projection, how to handle it is image to be projected turn into projected image, then with two kinds of processing modes, both
Processing mode, which can be divided into from software aspects, to be handled, and is handled from hardware aspect.
The essence of software aspects processing is adjusted in itself from image to be projected, to obtain projected image.
The essence of hardware aspect is, it is not necessary to adjust it is image to be projected itself, and carried out from the hardware aspect of electronic equipment
Adjustment, to obtain projected image.
If specifically, it is adjusted in itself from image, then S102 detailed process is as follows：
1st step, projected image is adjusted to by image to be projected.
2nd step, to perspective plane on project projected image so that on the projection surface formed perspective plane image.
Wherein, the 3rd contrast of projected image is identical with the second contrast.
In the processing procedure of the 1st step, because image is characterized by gray value or rgb value in itself, if with gray scale
Value citing, during Image Adjusting, specifically adjusts gray value image to be projected, and before adjustment, it can also perform
Following step：
1. the walks, first image on perspective plane is included by image acquisition units collection one.
The main purpose of the first image now gathered, it is in order to obtain the gray value on perspective plane, in order to based on projection
The gray value in face adjusts gray value image to be projected.Assuming that perspective plane is white, then gathers the ash of the first image of acquisition
Angle value just should be 255, because gray scale refers to the color depth at black white image midpoint, typically from 0 to 255, white is scope
255, black 0.
2. the walks, the first image is analyzed, and obtains and is used for the second gray value for characterizing perspective plane in the first image.
After collecting the first image, and it is analyzed, the second gray value corresponding to the image will be obtained.If
By taking black perspective plane as an example, then the second gray value now obtained should be just 0.
When obtaining the second gray value, then then can be adjusted to projected image by image to be projected.Specifically, can have
Two kinds of methods of adjustment, the first be by the gray value in first edge region image to be projected it is integrally-regulated be the second gray value,
Another kind is that first edge region is divided into N number of subregion, and the gray value of each sub-regions is adjusted to different value, to obtain
Obtain the effect of gradual change.
The detailed process of first method is then as follows：
First, a triggering command is obtained.
Wherein, triggering command is specially that first edge region is adjusted to the instruction of the second gray value.In general, project
Face is pure color mostly, such as ater, therefore the gray value in the first image obtained is nearly all 0.Therefore, in order that
The difference of the gray value of one fringe region and the gray value on perspective plane reduces, and triggering command now is specifically by first edge area
Domain is adjusted to the instruction of the second gray value.
Secondly, based on triggering command, first gray value in first edge region is adjusted to the second gray value, projected
Image.
The detailed process of second method is then as follows：
First, by first edge region division for N number of edge subregion.As shown in figure 3, first edge region includes
N number of edge subregion, N number of edge subregion include the 1st edge subregion, the 2nd edge subregion ... N edges sub-district
Domain, and the 1st edge subregion is the edge subregion near the first central area, wherein N >=2 and N is integer.If with the limit
Exemplified by, then first edge region can at least be divided into 2 edge subregions.
Specifically, after by first edge region division for N number of edge subregion, it is adjusted to throw by image to be projected
The detailed process of shadow image is as follows：
According to the 1st edge subregion, the order of the 2nd edge subregion ... N edges subregion adjusts N number of edge sub-district
Domain so that the gray value of N number of edge subregion is according to the 1st edge subregion, the 2nd edge subregion ... N edges subregion
Order be gradually reduced.
For example, when adjusting the gray value of this N number of edge subregion, because gray value maximum is 255, minimum value 0,
Therefore, the gray value that it is adjusted to the 165, the 2nd edge subregion according to the gray value of the 1st edge subregion is adjusted to
The gray value of 123 ... N edges subregions is adjusted to 21, i.e., according to the order, extends according to central area to fringe region
Direction, the gray value of subregion is gradually turned down, to obtain projected image.
Because for image, the gray value of image is lower, after projection is gone out, image that user watches it is bright
Dark degree is smaller, and it is also just smaller with the contrast on perspective plane, and adjustment herein is to adjust first edge regional compartmentalization domain
It is whole, so the effect that projected image realizes gradual change can be reached.
Mode above is the embodiment being adjusted in terms of image is changed, and lower mask body introduction is from electronic equipment
