Step 201, obtains the image of shade to be added;
Electronic equipment in use, can show various images on the display screen of electronic equipment, such as image of icon, cursor or other types etc.
Can from the image of these demonstrations, obtain as requested the image of shade to be added.
In actual applications, in the time obtaining the image of shade to be added, electronic equipment can be according to the image of the shade to be added showing in predetermined Requirement Acquisition display screen.
By way of example, if need to add shade to the who object in game, now electronic equipment is opened this game, on corresponding display screen, may show who object and background image simultaneously, the corresponding image of these who object showing can be defined as requested to the image of shade to be added.
Again by way of example, if need to add shade to all images that show, obtain all images of current demonstration on display screen, and these images are defined as to the image of shade to be added.
Step 202, obtains the residing geographic position of electronic equipment, and record obtains obtaining the moment of geographic position;
In electronic equipment, can be provided with steady arm, such as based on GPS (Global Positioning System, GPS) or the steady arm of Beidou satellite navigation system (BeiDou Navigation Satellite System) etc., then obtain the residing geographic position of electronic equipment according to this steady arm.Generally, longitude and latitude that the geographic position obtaining according to steady arm can be positioned at the earth according to electronic equipment represent.
In the time getting the residing geographic position of electronic equipment, can also record and obtain obtaining the moment of this geographic position simultaneously.
Step 203, according to geographic position and obtain the moment, determines the ray that points to the central point of display screen from solar source;
Due to the relative angle in geographic position, solar source and geographic position and obtain the moment and have fixed relationship, therefore can and obtain the moment according to geographic position, determine the ray that points to the central point of display screen from solar source.
This ray points to the central point of display screen of electronic equipment from solar source, and and display screen between shape in an angle.
Step 204 is the light trend of solar source with respect to display screen by the orientation determination of ray;
Step 205, in the time that the image showing on display screen is two dimensional image, the edge according to image away from external light source, determines the shade corresponding with edge shape, shade has predetermined length;
For two dimensional image, the length of shade that can two dimensional image is set to identical, is set to predetermined length.The predetermined length that the shade at the edge said here has refers to when this shade is tiled and the relative distance of corresponding edge.
In two dimensional image, because the shape away from the edge of external light source in two dimensional image can determine the shape of shade, therefore can be according to image the edge away from external light source, determine the shade corresponding with edge shape.
Such as, when in two dimensional image away from the edge of external light source be shaped as straight-line segment time, the shape of corresponding shade is also identical with the shape of this straight-line segment; For another example, when in two dimensional image away from the edge of external light source be shaped as irregular lines time, the shape of corresponding shade is also identical with the shape of these irregular lines.
Refer to shown in Fig. 2 B, its show in the present invention part embodiment, provide according to the schematic diagram of the shade that in two dimensional image, the shape away from the edge of external light source produces.In Fig. 2 B, in two dimensional image b, be straight-line segment away from the edge b2 of external light source, the shape of the corresponding shade b4 producing is also the straight-line segment isometric with the straight-line segment of edge b2, and the predetermined length that this shade b4 has is b6.
Refer to shown in Fig. 2 C, its show in another part embodiment of the present invention, provide according to the schematic diagram of the shade that in two dimensional image, the shape away from the edge of external light source produces.In Fig. 2 C, in two dimensional image c, be irregular wave line away from the edge c2 of external light source, the shape of the corresponding shade c4 producing is also the irregular wave line isometric with the irregular wave line of edge c2, and the predetermined length that this shade c4 has is c6.
Step 206, determines that light moves towards the indicated direction of projection on display screen, adds shade and shows at this edge according to this direction;
Because this direction is to determine that light moves towards the indicated direction of projection on display screen, the shade therefore adding on the edge away from light source in two dimensional image according to this direction can be in this two dimensional image region in addition.
Refer to shown in Fig. 2 D, indicated direction of projection of moving towards on display screen according to light providing in part embodiment of the present invention is provided for it is the schematic diagram that image adds shade.In Fig. 2 D, the screen center of solar source d2 and electronic equipment has determined that light moves towards d4, this light moves towards d4 and be projected as ray d6 on display screen, the direction of this ray d6 is label orientation d8 in figure, because solar source d2 is positioned at the upper right side of electronic equipment, therefore in two dimensional image, the edge d10 of lower left is the edge away from solar source, now adds shade d12 and shows at this edge d10 according to direction d8.
Step 207, in the time that the image showing on display screen is 3-D view, determines the angle between light trend and display screen;
Because 3-D view has respective heights, this highly can determine the length of shade, and the height of 3-D view determines the relative distance of shade when by tiling and between 3-D view.Therefore, adding when shade and some difference of two dimensional image for 3-D view.
In the time determining the shade that will add for 3-D view, need to be according to the length of the definite shade such as angle and the shade amplification coefficient of setting between the height of 3-D view, light trend and display screen.
Because light trend is the ray of external light source to the center of the display screen of electronic equipment, therefore can determine the angle between light trend and this display screen.
Step 208, according to the shade amplification coefficient of the height of the image of the tangent value of this angle, shade to be added and setting, calculates the length of the shade corresponding with image;
In actual applications, electronic equipment is moving towards the tangent value of the angle between display screen, the height of image and the shade amplification coefficient of setting of shade to be added according to light, while calculating the length of the shade corresponding with image, can comprise:
The first, the tangent value by the height of the image of shade to be added divided by angle, obtains quotient;
The second, quotient is multiplied by shade amplification coefficient, obtain the length of the shade that image is corresponding.
Hence one can see that, and the length of shade is at least to move towards angle between display screen and the height of 3-D view decides by light.
As adjusted the effect of shade, can utilize amplification coefficient to zoom in or out the shade length obtaining.This amplification coefficient can be set according to hatching effect, and this amplification coefficient is to be greater than 0 numerical value.When amplification coefficient is to be greater than 0 while being less than 1 numerical value, the shade obtaining according to the height of 3-D view is dwindled; When amplification coefficient is, while being greater than 1 numerical value, the shade obtaining according to the height of 3-D view to be amplified.
