Wherein, original dynamic shadow region is the shadow region comprising monoblock word, and the shadow region can be rectangle, circle
The regular shapes such as shape, heart, may also be irregular shape.
S102, the original dynamic shadow region area is reduced according to preset rules, obtain reducing dynamic shadow
Region.
Specifically, this step can include following two implementations：
Mode one：The original dynamic shadow region area is reduced according to preset ratio；
For example for the original dynamic shadow region of rectangle in Fig. 7, the length and width of rectangle can be simultaneously reduced to original
/ 3rd of length, then rectangular area be reduced to 1/9th of original area, so, the amount of calculation to dynamic shadow can contract
It is small nearly 9 times, calculation process speed is improve, effectively reduce the Caton phenomenon of terminal applies.
Mode two：
This mode is applied to the scene of dynamic shadow region one direction movement, for example：Desktop and this word list of screen locking
To mobile scene.Wherein, as shown in figure 8, desktop text moving direction is horizontal, i.e., along capable direction.Desktop text has
Original dynamic shadow region Q, caches the corresponding m rows of original dynamic shadow region Q, n and arranges by memory module 61, summation module
622 pairs of vertical shading region moving directions, the i.e. pixel to column direction are sued for peace, and as a result need to only retain n pixel.Then desktop text
When mobile, the amount of calculation to dynamic shadow can reduce m times, improve calculation process speed, effectively reduce the interim card of terminal applies
Phenomenon.
Screen locking character motion direction is vertical, then summation module 622 is to vertical shading region moving direction, i.e., to line direction
Pixel summation, as a result need to only retain m pixel of column direction.Then during screen locking character motion, the amount of calculation to dynamic shadow can
N times is reduced, calculation process speed is improve, the Caton phenomenon of terminal applies is effectively reduced.
S103, the Shadow Parameters for determining the reduction dynamic shadow area pixel.
This step is specifically included：
S1030, determine reduction dynamic shadow area pixel position in the corresponding pixel position in the original dynamic shadow region
Put；
Exemplary, if the length and width in the original dynamic shadow region of rectangle is respectively reduced into 2 times, original dynamic can be determined
Every two location of pixels in location of pixels correspondence reduction dynamic shadow region in shadow region.For example, in Fig. 9, it is original
1,4, No. 7 pixels correspond to 1,2, No. 3 pixels in reduction dynamic shadow region respectively in dynamic shadow region.
S1031, the Shadow Parameters of the collection original dynamic shadow region respective pixel position are used as the reduction dynamic
The Shadow Parameters of shadow region pixel.
Wherein, the Shadow Parameters include：Shadow color, shade direction, viewpoint.
S104, assignment is carried out to reduction dynamic shadow region respective pixel according to the Shadow Parameters.
