Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Embodiment one, and referring to Fig. 1, the embodiment of the invention provides a kind of method of adjusting background image colour parameter:
Step 101: receive Background;
Step 102: whether the color parameter (RGB) of judging Background meets the first color parameter scope that presets; If then execution in step 103; Execution in step 104 then if not:
Step 103: jump out this flow process;
Step 104: increase by one on the Background and meet the second figure layer that presets color parameter, just cover plate;
Step 105: redistribute the color parameter of described Background and described figure layer by preset weight, and calculate the Background redistributed and described figure layer color parameter and;
Described in this step redistribute color parameter with calculate color parameter and concrete grammar be:
RB＝RA×T+RM×(1-T)；
GB＝GA×T+GM×(1-T)；
BB＝BA×T+BM×(1-T)；
Wherein, RA, GA, BA represent the color parameter component value of described each pixel of Background respectively, and RM, GM, BM represent that respectively second of described figure layer presets the color parameter component value.T represents the preset weight value, and 0≤T≤1; RB, GB, BB represent the described one-component value that is used to upgrade background image colour parameter respectively.
Step 106: redistribute the color parameter of described Background and described figure layer by preset weight, and with the color parameter of described Background of redistributing and described figure layer and, upgrade described Background and the color parameter of scheming the laminated new Background that becomes.
For example, when this method was applied to the color parameter adjustment of mobile phone Background, the first color parameter scope that we preset was 50≤R≤205; 50≤G≤205; 50≤B≤205; If the color parameter of the Background that receive this moment has exceeded this scope; So just meet the second figure layer that presets color parameter with increasing by one on the Background; This second presets color parameter and sets in advance for the user, is RM:255, GM:255, BM:255; And the user can set in advance a weighted value T, and the meaning of this weighted value T is exactly when showing the figure layer that increases, the transparency of this figure layer color.And the span of this weighted value is 0≤T≤1.If T gets 1, then described figure layer just expression is transparent fully, so just can't see the color of covering plate fully; If T gets 0, then expression is opaque fully, so just only sees the color of figure layer, and can't see the color of Background fully.If T is set to 0.5, then to represent translucently, the color of so described figure layer and Background can both be in sight.Therefore by the numerical range of weighted value T is set, when figure layer and Background were synthesized a new Background and upgrade the color parameter of Background, the color relation of new Background can reach the effect that the user envisions.
If original background image colour parameter is RA:30, GA:30, BA:30; Second to preset color parameter be RM:255, GM:255, BM:255; Preset weight T is 0.5; Calculate by following three formula:
RB＝RA×T+RM×(1-T)＝30×0.5+255×0.5＝142.5
GB＝GA×T+GM×(1-T)＝30×0.5+255×0.5＝142.5
BB＝BA×T+BM×(1-T)＝30×0.5+255×0.5＝142.5
So new RB, GB, BB are respectively 142.5,142.5,142.5; New RB, GB, BB numerical value are upgraded described figure layer and the synthetic new background image colour parameter of Background, just reached the purpose of desalination background image colour value.
Can certainly reach desalination Background and the purpose of deepening background image colour by different T values being set, presetting the first different color parameter scopes.
