First embodiment
A kind of projecting method is embodiments provided, and projected image is made by adjusting the borderline region of projected image
Borderline region and view field's image are adapted, then by adjustment after projector, image projection realize Rimless to view field
Drop shadow effect.Fig. 2 is referred to, the method includes：
Step S110：Control image capture device carries out IMAQ to view field, gets view field's image.
Specifically, Fig. 3 is referred to, and control image capture device carries out IMAQ to view field, gets projected area
Area image includes：
Step S111：Determine view field position.
The projective parameter of projector equipment is obtained, the projective parameter is the parameter that user is set in projector equipment, according to
Projective parameter can obtain the projecting direction of projector equipment and projected size, may thereby determine that out view field in projection
Position in background.
Step S112：According to view field position, image capture device acquired projections area image is controlled.
The size of position and view field according to view field in projected background, can control IMAQ
IMAQ is carried out after equipment adjusting parameter to view field, and the position of the collection image is view field, gets projection
Area image.The content of view field's image of acquisition is consistent with the content of view field, not comprising throwing in view field's image
The overseas projected background in shadow zone.
Step S120：The color of comparison view field's image and the color of projected image borderline region.
Also included before step S120：
Reading projecting picture；The projected image is divided into borderline region and zone line.
Reading needs the projected image for projecting to view field, the size of the projected image and the size of view field
Identical.
In the present embodiment, the corresponding projected image is respectively accounted in the centre position of the projected image according to length and width
Length and width preset ratio marks off zone line, and the center of the zone line is same with the mesophase of the projected image, described
The remaining region of the zone line is removed in projected image for borderline region.In the projected image, during zone line is
Between rectangular area, borderline region is the remaining region in rectangular area in the middle of projected image is removed.
Fig. 4 is referred to, Fig. 4 represents a projected image, wherein, projected image 105 is divided into zone line 106 and side
Battery limit (BL) domain 107, wherein, projected image 105 is the rectangular area larger relative to middle rectangle, and zone line 106 is middle
Rectangular area, borderline region 107 be larger rectangular area in remove centre rectangular area region.
Certainly, the concrete numerical value of preset ratio is not intended as limiting in the present embodiment, can according to the actual requirements and bar
Part and adjust.
The color of view field's image includes that tri- color of R, G, B, the color of the borderline region of the projected image include
Tri- color of R, G, B.
Specifically, Fig. 5 referred to, the color of comparison view field's image and the borderline region of projected image
Color includes：
Step S121：Three colors of three colors of view field's image with the borderline region of the projected image are asked respectively
Difference, obtains three aberration.
Ask in the colour of R in the color of view field's image and the color of the borderline region of the projected image
R colour difference, obtain the first difference.
Ask in the colour of G in the color of view field's image and the color of the borderline region of the projected image
G colour difference, obtain the second difference.
Ask in the colour of B in the color of view field's image and the color of the borderline region of the projected image
B colour difference, obtain the 3rd difference.
Step S122：Judge three aberration whether in the range of preset difference value respectively.
Whether set preset difference value scope judges the first difference, the second difference and the 3rd difference described as 0-5, respectively
In the range of preset difference value.Specifically, the preset difference value scope of each difference corresponding of setting is not intended as limiting, and can be every
The preset difference value scope of one difference is identical, or preset difference value scope of each difference is different, can be according to reality
Demand and condition and set
In the present embodiment, the concrete setting of preset difference value scope is not intended as limiting, it is also possible to be set as other scopes.
Step S123：If three aberration are in the range of preset difference value, the color of view field's image is judged
Identical with the color of the borderline region of the projected image.
Three aberration are respectively corresponding first differences of R, corresponding second differences of G and corresponding 3rd differences of B, if
First difference, the second difference and the 3rd difference judge view field's image in the range of the preset difference value, then
Color is identical with the color of the borderline region of the projected image.If had in the first difference, the second difference and the 3rd difference
One difference then judges the color of view field's image and the side of the projected image not in the range of the preset difference value
The color in battery limit (BL) domain is different.
Step S130：If the color of view field's image is different from the color of the borderline region of projected image, press
According to the borderline region that preset standard adjusts the projected image, the borderline region is made to be adapted with the view field.
If the color of view field's image is different from the color of the borderline region of projected image, according to preset standard
The borderline region of the projected image is adjusted, the borderline region is adapted with the view field.Specifically, if described
The color of view field's image is different from the color of the borderline region of projected image, adjusts the projected image according to preset standard
Borderline region, being adapted the borderline region and the view field includes：
If the color of view field's image is different from the color of the borderline region of the projected image, by the side
Battery limit (BL) domain ecto-entad adjusts transparency by different level, or, the borderline region ecto-entad is adjusted to and projected area by different level
Domain identical color.
It is by different level by the transparency of the borderline region that the borderline region ecto-entad is adjusted transparency by different level
Ecto-entad successively decreases adjustment according to 100% to 0 by different level.The borderline region ecto-entad is adjusted to and projected area by different level
Domain identical color be by the borderline region ecto-entad according to by different level according to adjusting with view field identical color,
Wherein, the color of the borderline region outermost is identical with the color of view field, the phase of ecto-entad and the color of view field
Reduce like degree.It is adapted with view field so as to reach borderline region.
If the color of view field's image is identical with the color of the borderline region of projected image, the projected image
View field do not adjust.
Step S140：Projector, image projection after projector equipment is controlled by adjustment is to the view field.
If the color of view field's image is different from the color of the borderline region of projected image, control projection sets
Standby by adjustment after projector, image projection to the view field.
If the color of view field's image is identical with the color of the borderline region of projected image, control projection sets
The projector, image projection of the standby borderline region that will not pass through adjustment projected image is to the view field.
After projected image after by adjustment carries out projecting to view field, the borderline region of the image of view field is projected to
Color and view field background color without larger difference, be not in obvious line of demarcation, so as to being not in obvious
Border effect, that is, realize the drop shadow effect of Rimless.
