In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the realization flow figure of the preview display method of taking pictures that the embodiment of the present invention one provides;
Fig. 2 is the composition structure chart of the preview display unit of taking pictures that the embodiment of the present invention two provides.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In order to technical solutions according to the invention are described, be described below by specific embodiment.
embodiment one:
When the camera function that user starts mobile terminal is taken pictures, the real-time scene of taking pictures showing camera and get of display screen meeting of mobile terminal, at this moment, user can take pictures scene to carry out selecting scape by display screen preview, when pressing shutter by touch-screen or button, complete taking pictures to scene of taking pictures.Based on above-mentioned principle of taking pictures, in order to allow better effects if of taking pictures, this enforcement considers the colour temperature of scene of taking pictures when taking pictures, and provides one and to take pictures preview display method, Fig. 1 shows the preview Display Realization flow process of taking pictures that first embodiment of the invention provides, and details are as follows for its process:
Step S11, starts the camera preview of mobile terminal and to take pictures the color temperature value of scene, scene of taking pictures described in analyzing.
In the present embodiment, in scene of being taken pictures by display screen preview to carry out selecting the scape stage, the color according to scene of taking pictures forms, and adopts image analysis software real-time analysis to go out the color temperature value of this scene of taking pictures.
As one embodiment of the invention, described in analyze described in take pictures the step of color temperature value of scene, Ke Yiwei:
Analyze the RGB tone of scene of taking pictures, the color temperature value of scene of taking pictures described in calculating.
Particularly, after the composition getting the redness of rgb color pattern of scene of taking pictures, green and blue three kinds of colors, the color temperature value of scene of taking pictures can be calculated; Such as: by redness 57, green 59, the blue 54 warm-toned scenes of taking pictures formed, its color temperature value is about 3500K; By the scene of taking pictures of redness 48, green 52, blue 59 cool tones formed, device color temperature value is about 9000K.
Step S12, adjusts the color temperature value of display screen with the picture of taking pictures of scene of taking pictures described in preview according to the color temperature value of described scene of taking pictures.
In the present embodiment, after the color temperature value of the scene that goes out to take pictures to be analyzed, to the color temperature value correspondence adjustment of the display screen of mobile terminal; Thus, the colour temperature of the picture of taking pictures demonstrated in display screen and the true colour temperature of described scene of taking pictures more close, enhance the changes in temperature sensation of image, described in take pictures picture for described in take pictures the photo of scene.
As one embodiment of the invention, when display screen is LCDs, the step of the color temperature value of the color temperature value adjustment display screen of scene of taking pictures described in described basis, Ke Yiwei:
According to the color temperature value of described scene of taking pictures, the GAMMA parameter of adjustment display screen is to adjust the color temperature value of display screen.
Particularly, after the color temperature value of the scene that goes out to take pictures to be analyzed, according to the brightness display curve of liquid crystal display, the brightness of LCDs is adjusted (namely GAMMA corrects), so that the color temperature value of LCDs is adjusted to color temperature value immediate with scene of taking pictures.It should be noted that, the mode of the brightness of adjustment LCDs is: change the redness of rgb color pattern, green and blue composition and ratio, to change GAMMA value.
More optimizedly, the color temperature value of scene of taking pictures described in described basis, the GAMMA parameter of adjustment display screen with before the step adjusting the color temperature value of display screen, described in preview display method of taking pictures comprise:
The GAMMA value arranging display screen is N level, arranges N number of color temperature value interval simultaneously, and set up N number of color temperature value interval respectively with the mapping relations table of the GAMMA value of N level, described N is positive integer;
Therefore further, the color temperature value of scene of taking pictures described in described basis, the GAMMA parameter of adjustment display screen is to adjust the step of the color temperature value of display screen, Ke Yiwei:
Interval according to the color temperature value at the color temperature value place of described scene of taking pictures, search described mapping relations table to obtain GAMMA value;
The GAMMA parameter of display screen is set according to described GAMMA value.
Regulate the speed for the ease of using and improving, in advance the GAMMA value of display screen is set as N level, the corresponding GAMMA value of every one-level.Simultaneously, preset N number of color temperature value interval, the interval size in each color temperature value interval needs setting according to taking pictures, do not limit at this.Then, in mapping relations table, the mapping relations one by one in N number of GAMMA value and N number of color temperature value interval are set up.Such as: setting N is 4,4 GAMMA values are A, B, C, D, wherein, A<B<C<D, 4 range of color temperature of 4 GAMMA value correspondences are respectively: 3000K ~ 4499K, 4500K ~ 5999K, 6000K ~ 7499K, 7500K ~ 9000K.
Interval according to the color temperature value at the color temperature value place of described scene of taking pictures, search described mapping relations table, obtain GAMMA value; Thus, select this GAMMA value by the GAMMA optimum configurations hurdle at display screen, to complete the colour temperature adjustment of display screen; Such as: when the color temperature value of scene of taking pictures is 5000K, it is interval that this color temperature value is in 4500K ~ 5999K color temperature value, thus select B to correct to complete GAMMA as the GAMMA value of LCDs, thus complete the colour temperature adjustment of display screen.It should be noted that, LCDs can adjust the redness of rgb color pattern, green and blue composition and ratio to obtain GAMMA value, correct to complete GAMMA, realize the real-time color temperature value according to scene of taking pictures of display screen and be adjusted accordingly, the photo allowing display screen show also has cold and warm tone.
In the present embodiment, by mobile terminal camera, preview is taken pictures scene, according to the composition of the RGB tone of scene of taking pictures, analyze the colour temperature of this scene of taking pictures; Corrected to complete GAMMA by the GAMMA parameter adjusting LCDs, thus color temperature value is modulated to the close color temperature value of the color temperature value of scene of taking pictures by LCDs; Therefore, this enforcement is effectively for the color temperature value of scene of taking pictures, and the color temperature value of adjustment display, to help user to select scape better, shoots that have cold and warm tone, that effect is better photo, have more hommization.
