The embodiment of the invention discloses a kind of camera focusing method and terminal.Simplify focus operation, improve the flexibility of focusing.
Refer to Fig. 1, Fig. 1 is the schematic flow sheet of the first embodiment of a kind of camera focusing method disclosed in the embodiment of the present invention, and the method is by detecting the optical parameter of current environment; Judge whether the optical parameter of current environment meets pre-conditioned; If meet pre-conditioned, then the first focusing mode is adopted to focus; If do not meet pre-conditioned, then the second focusing mode is adopted to focus.The present embodiment is described from the angle of terminal.As shown in Figure 1, terminal completes the focusing of camera as follows, comprises the following steps.
101, the optical parameter of current environment is detected.
Because different focusing modes accuracy of focusing under different optical parameters there are differences, in some possible execution modes of the present invention, the optical parameter of current environment can be the parameter such as brightness value, tone of current environment; Wherein, the optical parameter of current environment can be the optical parameter of current environment residing for the terminal that sensed by transducer, such as, and the brightness value of the current environment detected by luminance sensor; In actual applications, the optical parameter of current environment also can be the tone of the picture in the view-finder of the camera of terminal.In feasible execution mode, the brightness value of current environment also can obtain in the following way: detect the image in camera view-finder by imageing sensor, then image processor obtains the brightness value of current environment according to the image that imageing sensor transmits.
102, judge whether the optical parameter of current environment meets pre-conditioned.
Wherein, the pre-conditioned optical parameter according to current environment is arranged.Such as, if the optical parameter of current environment is the brightness value of current environment, a brightness value can be set as the luminance threshold preset, pre-conditionedly can be: judge whether current environment brightness value is greater than default luminance threshold; If current environment brightness value is greater than default luminance threshold, be then defined as meeting pre-conditioned; If current environment brightness value is not more than default luminance threshold, be then defined as not meeting pre-conditioned.Such as from dark to the brightest brightness value that arranges for from 0 to 100, if arranging luminance threshold is X, if the brightness value that luminance sensor detects current environment is X1 (X1>X), due to X1>X, then current environment brightness value is greater than default luminance threshold, then the optical parameter of current environment meets pre-conditioned; If the brightness value that luminance sensor detects current environment is X1 (X1≤X), due to X1≤X, then current environment brightness value is less than default luminance threshold, then the optical parameter of current environment does not meet pre-conditioned.
Be understandable that, in some possible execution modes of the present invention, the optical parameter of described current environment can be the tone of picture in camera view-finder, wherein, tone refers to the global judgement of a width picture integral color, is the basic tendency of a width picture color.Tone can consider from lightness, purity, these three key elements of form and aspect.Wherein, lightness is eyes to the sensation of the bright-dark degree of light source and body surface, a kind of visual experience mainly determined by light intensity.All there is light and shade change in any color.Wherein yellow lightness is the highest, and purple lightness is minimum, and green, red, blue, orange lightness is close, is intermediate lightness.The change of the depth is also there is in addition in the lightness of same form and aspect.As having from shallow to deep in green, powder is green, pale green, the lightness such as emerald green change.Purity refers to the vividness of color, and a kind of vividness of color depends on the radiative single degree of these form and aspect.The look of monochromatic light feature that what human eye can distinguish have, all has certain vividness.Different form and aspect not only lightness are different, and purity is not identical yet.Form and aspect are primary features of color, are the standards the most accurately distinguishing various different color.Color beyond any black-white-gray has the attribute of form and aspect, and form and aspect are namely made up of primary colors, secondary color and secondary color.Tone also can be weighed from another one angle, such as cool tone and warm tones.A key property of color is " colour temperature ", and this is the natural reaction of people to color.For most people, colour system that is orange, yellow and red end is always associated with warm, ardent etc., is thus referred to as warm tones.Blue series is then connected with tranquil, easy, pleasantly cool, is just referred to as cool tone.
In some possible execution modes of the present invention, can preset a certain tone is default tone, if the tone of picture meets default tone in camera view-finder, is then defined as meeting pre-conditioned; If the tone of picture does not meet default tone in camera view-finder, be then defined as not meeting pre-conditioned.If be warm tones than the tone preset, if the tone that tone transducer detects picture in camera view-finder is warm tones, be then defined as meeting pre-conditioned; If the tone that tone transducer detects picture in camera view-finder is cool tone, be then defined as not meeting pre-conditioned.
If 103 meet pre-conditioned, then the first focusing mode is adopted to focus; If do not meet pre-conditioned, then the second focusing mode is adopted to focus.
Existing focusing technology mainly contains three kinds: contrast focusing, detecting phase focusing and laser focusing.Wherein, contrast is focused, and this is a kind of traditional focusing technology, is the contrast change of picture residing for focus, finds the lens location that contrast is maximum.Detecting phase is focused, and adds and shelters pixel in the imageing sensor adopted, the distance between pixel, in conjunction with their relative change, help system can determine that camera lens needs for accurately focusing and how far moves.Laser is focused, and normally infrared pulse light beam repeatedly calculates launch time through electronic measuring device, sets up an accurate scope, and image processor calculates concrete object or how far scene has actually, is locked in the optimal focus depth of field simultaneously.
In actual applications, can choose two kinds of focusing modes in advance as the first focusing mode and the second focusing mode, whether pre-conditioned according to meeting, camera focusing mode adopts the first focusing mode or the second focusing mode.
Such as, if the optical parameter of current environment is the brightness value of current environment, if the brightness value X1 of current environment is greater than default threshold values X, then meet pre-conditioned, now camera focusing mode adopts the first focusing mode; If the brightness value X1 of current environment is less than default threshold values X, then do not meet pre-conditioned, now camera focusing mode adopts the second focusing mode.
In some possible execution modes of the present invention, the first focusing mode can choose detecting phase focusing, and the second focusing mode can choose laser focusing.
The embodiment of the present invention, by detecting the optical parameter of current environment; Judge whether the optical parameter of current environment meets pre-conditioned; If meet pre-conditioned, then the first focusing mode is adopted to focus; If do not meet pre-conditioned, then the second focusing mode is adopted to focus.Automatically switch between the first focusing mode and the second focusing mode according to judged result, simplify focus operation, improve the flexibility of focusing.

Particularly, in some possible execution modes of the present invention, can define from dark to the ambient brightness value of the brightest correspondence is from 0 to 100, uses transducer to detect the brightness value of current environment.Because detecting phase focusing is focused not accurate enough under darker environment, laser focusing is stronger to ambient brightness adaptability, the right accuracy improving focusing, in an alternate embodiment of the invention, a default ambient brightness value X can be set, such as 60, if the brightness value of current environment is greater than default ambient brightness value X, then adopt detecting phase focusing, if the brightness of current environment is not more than default ambient brightness value X, then adopt laser focusing.
If the brightness value of 303 current environments is greater than default ambient brightness value, camera adopts detecting phase focusing.
Particularly, if the brightness value X1 of current environment is greater than default ambient brightness value X, i.e. X1>X, then camera focusing mode adopts detecting phase to focus, if than X1=80, then camera adopts detecting phase focusing.
If the brightness value of 304 current environments is not more than default ambient brightness value, stylus adopts laser focusing.
Particularly, if the brightness value X1 of current environment is not more than default ambient brightness value X, i.e. X1≤X, then camera focusing mode adopts detecting phase to focus, if X1>X, if than X1=80, then camera adopts detecting phase focusing.If X1≤X, if than X1=20, then camera adopts laser focusing.
The embodiment of the present invention, detecting phase focusing is utilized to focus not accurate enough under darker environment, the feature that laser focusing is stronger to ambient brightness adaptability, using the brightness value of current environment as environmental parameter, if the brightness value of current environment is greater than default ambient brightness value, then adopt detecting phase focusing, if the brightness of current environment is not more than default ambient brightness value, then adopt laser focusing, thus, improve the accuracy of camera focusing.
