Embodiment
For making the object, technical solutions and advantages of the present invention clearer, hereinafter in connection with accompanying drawing, embodiments of the invention are elaborated.It should be noted that, in the situation that not conflicting, the combination in any mutually of the feature in embodiment and embodiment in the application.
Can in the computer system such as one group of computer executable instructions, carry out in the step shown in the flow chart of accompanying drawing.And, although there is shown logical order in flow process, in some cases, can carry out shown or described step with the order being different from herein.
Along with the development of mobile communication technology, the application of micro projection is more and more.And camera has become the standard configuration of portable communication apparatus such as mobile phone etc.
The application's embodiment is based on existing micro projection, in conjunction with a kind of micro-throwing based on smart mobile phone of the first-class proposition of shooting scheme of automatically focusing.Certainly, the application's embodiment also can be applied in other various electronic with projecting function.
The projecting method of the embodiment of the present application is mainly used on electronic equipment, and this electronic equipment includes projecting cell, and this projecting cell is set on a perspective plane projection picture of publishing picture.As shown in Figure 1, the projecting method of the embodiment of the present application mainly comprises following content.
Step S110, electronic equipment, based on one first focal length, utilize its projecting cell on this perspective plane, to carry out projection, and projection goes out one first image.Wherein, this perspective plane is such as being projection screen or metope etc.
Step S120, electronic equipment obtains one first parameter information of this first image.
Step S130, electronic equipment is based on this first parameter information, by first Focussing to the second focal length of electronic equipment.
Step S140, electronic equipment utilizes this second focal length, carries out projection on the perspective plane of electronic equipment, and projection goes out one second image.The definition of this second image, higher than the definition of this first image.
In the application's embodiment, the first parameter information of this first image, can be specifically the definition of the first image.Now, electronic equipment can also comprise an image capture module, it is set to utilize projecting cell on perspective plane, to carry out after projection projection go out the first image at electronic equipment, gather the image information of the first image, and draw the definition of the first image according to the image information analysis of the first collected image.
In the application's embodiment, electronic equipment, based on this first parameter information, by the first Focussing to the second focal length of electronic equipment, can be undertaken by the mode of attempting.By continuous change focal length analysis, the parameter information of projected image under different focal, obtains the second image that definition is better than the first image.
Such as, in the time that this parameter information is the definition of image, adopt focusing evaluation function to obtain the also definition of analysis image.Carry out projection at electronic equipment based on the first focal length and projection goes out after the first image, this first image is analyzed, obtain the definition of this first image.
Then be, another focal length from the first Focussing.
Wherein, be another focal length from the first Focussing, can be to increase focal length, can be also to reduce focal length.Be adjusted into after this another focal length, electronic equipment utilizes this another focal length, carries out projection on the perspective plane of electronic equipment, and projection goes out another image that is different from this first image.
In general, changing before and after the focal length of electronic equipment, draw the probability of identical this situation of two width image definitions, is minimum, and therefore the application's embodiment does not do deep description to this situation.The focal length of twice imaging before and after this situation appears at, one of them is greater than preferably corresponding focal length of imaging definition, and another is less than preferably corresponding focal length of imaging definition.
And, even if the definition of gained two width images cannot effectively be distinguished before and after change focal length, also can be by again changing focal length, obtain the 3rd width image and with before two width images in a width carry out definition comparison, then according to comparative result adjusting focal length again, also can avoid electronic equipment identical but be not all the adjustment of carrying out back and forth focal length under better situation in two width image definitions.
Increasing focal length, also this another focal length is greater than under the situation of the first focal length, if the definition of another image of this of gained is good and the definition of this first image, can be the 3rd focal length that is greater than this another focal length from this another Focussing.Electronic equipment utilizes the 3rd focal length, carries out projection on the perspective plane of electronic equipment, obtains corresponding to this trifocal the 3rd image.If the definition of the 3rd image definition of this another image is better, can also continue to increase focal length and carry out projection.Until while there is image definition variation, by corresponding piece image best definition focal length, carry out the preferred focal length of projection as electronic equipment.
Reducing focal length, also this another focal length is less than under the situation of the first focal length, if the definition of another image of this of gained is good and the definition of this first image, can be the 3rd focal length that is less than this another focal length from this another Focussing.Electronic equipment utilizes the 3rd focal length, carries out projection on the perspective plane of electronic equipment, obtains corresponding to this trifocal the 3rd image.If the definition of the 3rd image definition of this another image is better, can also continue to dwindle focal length and carry out projection.Until while there is image definition variation, by corresponding piece image best definition focal length, carry out the preferred focal length of projection as electronic equipment.
If this another focal length is greater than under the situation of the first focal length, or this another focal length is less than under the situation of the first focal length, the definition variation of the image that electronic equipment projection obtains, the adjustment direction that to illustrate from the first Focussing be this another focal length, the opposite direction of becoming better and better with desired definition, the now reverse size of adjusting focal length, carries out the trial of Focussing.
In the application's embodiment, the first parameter information of this first image, can be specifically also the range information between electronic equipment and the first image.Now, electronic equipment can also comprise that one apart from detecting unit, and it is set to detect the distance between perspective plane and electronic equipment, and the distance between this perspective plane and electronic equipment is the distance between aforesaid electronic equipment and the first image.
