Embodiment one:
In the embodiment of the present application, a kind of projecting method is provided.
The method is applied to an electronic equipment.
Electronic equipment in the embodiment of the present application can be panel computer, smart mobile phone, notebook computer, all-in-one, desktop computer, projecting apparatus etc.
And the electronic equipment in the application, can be common notebook computer, and be connected with projecting apparatus; Or with the electronic equipment of projecting function, as the smart mobile phone with projecting function, panel computer etc.
Please refer to Fig. 1 below, the specific implementation process of the projecting method in the embodiment of the present application is as follows:
S101, obtains image to be projected.
Wherein, the first central area image to be projected and the first fringe region have the first contrast.
S102, based on image to be projected, project a projected image on a perspective plane, makes to form a perspective plane image on the projection surface.
Wherein, the second central area and second fringe region of perspective plane image have the second contrast, and the second contrast is different from the first contrast.
In the implementation process of S101, image to be projected is obtained by image acquisition units collection and prepare the image that projects away.This image can be landscape, personage, or the image of other guide.In general, image has the parameter of luminance channel and the parameter of chrominance channel, and the parameter of luminance channel is exactly gray value, and the gray value of image itself to be used for the bright-dark degree of token image self, even if do not projected, image self Ye Shiyou bright-dark degree.The parameter of chrominance channel is RGB, is used for the colorfulness of token image.And if it is image to be projected to characterize in the embodiment of the present application with gray value, so when by centered by Region dividing image to be projected when region and fringe region, just there is clear and definite contrast.Please refer to Fig. 2, in Fig. 2, describe central area image to be projected and the division of fringe region.And for the ease of with subsequent treatment after image divide, at this by central area called after first central area image to be projected, fringe region called after first fringe region, and contrast called after first contrast of central area image to be projected and fringe region.
When obtain image to be projected after, then can perform subsequent step.
In the implementation process of S102, projected image be electronic equipment based on image to be projected, the image that the preparation obtained after a series of process projects away.And by projector, image projection on the projection surface time, then can form a perspective plane image on the projection surface, the ratio of the central area of perspective plane image now and the contrast of fringe region and the first contrast image to be projected is different.And for the ease of distinguishing, by central area called after second central area of perspective plane image, by its fringe region called after second fringe region, by contrast called after second contrast of the second central area and the second fringe region.
In addition, because electronic equipment is based on image to be projected, after a series of process, the projected image just obtained, therefore, contrast and the contrast to be projected of projected image are different.For the ease of distinguishing, by central area called after the 3rd central area of projected image, by its fringe region called after the 3rd fringe region, by contrast called after the 3rd contrast of the 3rd central area and the 3rd fringe region.Further, projected image is the same with the contrast of projection imaging image in fact, and namely the second contrast is the same with the 3rd contrast.
Further, based on image to be projected, a perspective plane project in the specific implementation process of a projected image, also there is implementation process below:
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 process the projected image that becomes image to be projected, then there are two kinds of processing modes, these two kinds of processing modes can be divided into from software aspect and processing, and process from hardware aspect.
The essence of software aspect process is, itself adjusts, to obtain projected image from image to be projected.
The essence of hardware aspect is, does not need adjustment image to be projected own, and adjusts from the hardware aspect of electronic equipment, to obtain projected image.
Concrete, if regulate from image itself, so the detailed process of S102 is as follows:
1st step, is adjusted to projected image by image to be projected.
2nd step, project projected image on perspective plane, makes to form perspective plane image on the projection surface.
Wherein, the 3rd contrast of projected image is identical with the second contrast.
In the processing procedure of the 1st step, because image itself is characterized by gray value or rgb value, if with gray value citing, in the process of Image Adjusting, specifically adjust gray value image to be projected, and before adjustment, also can perform step below:
1. walk, and comprised first image on perspective plane by image acquisition units collection one.
The main purpose of the first image now gathered is the gray value in order to obtain perspective plane, so that adjust gray value image to be projected based on the gray value on perspective plane.Suppose that perspective plane is for white, the gray value so gathering the first image of acquisition should be just 255, because gray scale refers to the color depth of black and white image mid point, scope is generally from 0 to 255, and white is 255, and black is 0.
2. the walk, and analyzes the first image, obtains the second gray value being used for characterizing perspective plane in the first image.
When collecting the first image, and after analyzing it, the second gray value that this image is corresponding will be obtained.If for black perspective plane, the second gray value so now obtained should be just 0.
When obtaining the second gray value, so then projected image can be adjusted to by image to be projected.Concrete, two kinds of methods of adjustment can be had, the first be by integrally-regulated for the gray value of the first fringe region image to be projected be the second gray value, another kind is that the first fringe region is divided into N number of subregion, the gray value of each subregion is adjusted to different value, to 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 the instruction the first fringe region being adjusted to the second gray value.In general, perspective plane is pure color, such as ater mostly, and the gray value in the first image therefore obtained is nearly all 0.Therefore, in order to the difference of the gray value of the gray value and perspective plane that make the first fringe region reduces, the first fringe region is specifically adjusted to the instruction of the second gray value by triggering command now.
Secondly, based on triggering command, the first gray value of the first fringe region is adjusted to the second gray value, obtains projected image.
The detailed process of second method is then as follows:
First, the first fringe region is divided in order to N number of edge subregion.As shown in Figure 3, first fringe region includes N number of edge subregion, and N number of edge subregion includes the 1st edge subregion, the 2nd edge subregion ... N edge subregion, and the 1st edge subregion is the edge subregion near the first central area, wherein N >=2 and N is integer.If for the limit, then the first fringe region is minimum can be divided into 2 edge subregions.
Concrete, after the first fringe region is divided in order to N number of edge subregion, by as follows for the detailed process being adjusted to projected image image to be projected:
According to the 1st edge subregion, 2nd edge subregion ... the order of N edge subregion adjusts N number of edge subregion, make the gray value of N number of edge subregion according to the 1st edge subregion, the 2nd edge subregion ... the order of N edge subregion reduces gradually.
Such as, when adjusting the gray value of this N number of edge subregion, because gray value maximum is 255, minimum value is 0, therefore, it is adjusted to 165 according to the gray value of the 1st edge subregion, the gray value of the 2nd edge subregion is adjusted to 123 ... the gray value of N edge subregion is adjusted to 21, namely according to this order, and the direction extended to fringe region according to central area, the gray value of subregion is turned down gradually, to obtain projected image.
Because for image, the gray value of image is lower, after projection is gone out, the bright-dark degree of the image that user watches is less, it is also less with the contrast on perspective plane, and adjustment is herein by the first fringe region subregion adjustment, so can reach the effect that projected image realizes gradual change.
Mode is above the embodiment carrying out from the aspect changing image adjusting, and lower mask body introduction changes from the structure of electronic equipment the embodiment carrying out adjusting.
Concrete, for the electronic equipment in the embodiment of the present application, electronic equipment has the first projection mode and the second projection mode, first projection mode is common projection mode, the i.e. projection mode of prior art, when by image to be projected projection, can not carry out processing and the projection mode directly projected away.Therefore, under the first projection mode, the second central area of projection imaging image and the second fringe region there is the first contrast.Namely its contrast is the same with contrast image to be projected.
And the second projection mode is the projection mode defined in the embodiment of the present application, under the second projection mode, electronic equipment can to image to be projected or adjust the component of self, to obtain projected image, and projected image and image to be projected be different, therefore, projected is gone out obtain projection imaging image time, second central area of projection imaging image and the second fringe region there is the second contrast, and contrast image to be projected is different.
And the first projection mode of electronic equipment and the second projection mode can switch, electronic equipment such as, be provided with a button, the projection mode pressing the button electronic equipment becomes the second projection mode, and the projection mode of the button electronic equipment that rebounds becomes the first projection mode.
Under the second projection mode, electronic equipment by adjustment mode image to be projected own, can obtain projected image, and the second projection mode support adjustment is now image to be projected, and under the second projection mode, electronic equipment structure now does not change; Certainly, electronic equipment directly can also adjust to the second projection mode from the first projection mode, and under the second projection mode, the structure of electronic equipment has some to change, below be just described from changing the configuration aspects of electronic equipment.
Further, this electronic equipment also comprises a projecting cell, and projecting cell now can be the projecting apparatus be connected with electronic equipment, also can be the projecting subassembly being built in electronic equipment.
Wherein, projecting cell has array light source, and array light source is now that projection is absolutely necessary, if projecting cell is the projecting apparatus be connected with electronic equipment, so namely array light source is the projection lamp assembly in projecting apparatus.
And array light source has central light source region and edge light region, when the projection mode of electronic equipment is different, the light source value in the edge light region of array light source is different, and electronic equipment can change the projection mode of electronic equipment by adjustment array light source.
Concrete, obtain the adjustment mode of projected image from the aspect of the hardware configuration of electronic equipment, specifically also have two kinds of methods.
The first is the edge light region of integrated regulation array light source, makes the brightness value of the fringe region entirety of the projected image of acquisition the same.
The second is divided into M light source subregion to adjust respectively in the edge light region of array light source, makes the fringe region of the projected image of acquisition reach the effect of brightness value gradual change.
The detailed process of the first adjustment mode is as follows:
Electronic equipment is adjusted to the second projection mode from the first projection mode, is specially:
The light source value in the edge light region of array light source is adjusted to the second value from the first value, is adjusted to the second projection mode to make electronic equipment from the first projection mode.Wherein, first is worth for electronic equipment is under the first projection mode, the light source value in edge light region.Second is worth for electronic equipment is under the second projection mode, the light source value in edge light region, and the first value is greater than the second value.
Concrete, herein by the edge light region of array light source light source value dim, be in order to when projection image to be projected for projection is gone out, the brightness value of the 3rd fringe region of the projected image of acquisition reduced, causes the brightness value of the second fringe region of projection imaging image to reduce further.And for projected image itself, its brightness value is can higher than the brightness value on perspective plane, there is a high-contrast between the two, now the brightness value of the second fringe region of projection imaging image is turned down, then can reduce the contrast of the brightness value on the second fringe region and perspective plane.So, from the angle of user's viewing, due to the reduction of contrast, then can not stimulate the eyes to user, and then the comfort level that user is watched improves, and improves the viewing experience of user.
The detailed process of the second adjustment mode is as follows:
Wherein, first by edge light Region dividing be M light source subregion.
Concrete, M light source subregion includes the 1st light source subregion, the 2nd light source subregion ... M light source subregion, the 1st light source subregion is the light source subregion near central light source region.
Further, electronic equipment is adjusted to the second projection mode from the first projection mode, specifically also comprises:
According to the 1st light source subregion, 2nd light source subregion ... the light source value of order adjustment M the light source subregion of M light source subregion, make the light source value of M light source subregion according to the 1st light source subregion, the 2nd light source subregion ... the order adjustment of M light source subregion reduces gradually.
Concrete, herein by the edge light region of array light source light source value dim gradually, in order to when projection image to be projected for projection is gone out, the brightness value of the 3rd fringe region of the projected image of acquisition is reduced gradually, causes the brightness value of the second fringe region of projection imaging image to reduce gradually further.And for projected image itself, its brightness value is can higher than the brightness value on perspective plane, there is a high-contrast between the two, now the brightness value of the second fringe region of projection imaging image is turned down gradually, then can reduce the contrast of the brightness value on the second fringe region and perspective plane gradually.So, from the angle of user's viewing, due to the reduction gradually of contrast, then can not stimulate the eyes to user, and then the comfort level that user is watched improves, and improves the viewing experience of user.
