As shown in Figure 1, this method may comprise steps of：
Step 101：When receiving the first operation of user, the object in drop shadow spread is captured using detection module；
The first operation of user is the operation that user's control wearable electronic equipment is projected, still, first operation
The tool way of realization present invention and without leading, if wearable electronic equipment is provided with physics or virtual projection button, the
One operation can be the operation that user triggers physics or virtual projection button, certainly, also other realization methods, as this
One operation can also be the operation for rocking wearable electronic equipment, such as detect that wearable electronic equipment is shaken parameter preset,
Then detection module is utilized to capture the object in drop shadow spread.
It should be noted that drop shadow spread is to project output module to export the range of project content；Specifically, projection is defeated
Go out module to be arranged in wearable electronic equipment, due to being limited by projection angle or projecting direction so that projection output
The range that module exports projected image has certain limitation, i.e., can only project project content in a certain range.Therefore,
In the present invention, detection module need to be utilized to capture the object in drop shadow spread.
Wherein, projection output module can export project content, which can be the defeated of wearable electronic equipment
Go out content, or can be the display content of wearable electronic equipment.
It is emphasized that the realization method of detection module can there are many, the present invention is not defined；Such as, mould is detected

The project content after adjustment is exported on object to control projection output module, it can be seen that, the present invention can realize certainly
The dynamic adjustment to project content simplifies user's operation, improves user experience.
In practical applications, wearable electronic equipment can be generally worn on by user in using wearable electronic equipment
Some position of body, such as smartwatch, Intelligent bracelet are worn in wrist.So, the projection of wearable electronic equipment
The object that project content is output to by output module can be human object.
Based on this, the embodiment of the present invention two discloses a kind of projection output method, is waited for what is different from the first embodiment is that obtaining
The characteristic parameter of view field, is specifically as follows：It obtains and the relevant characteristics of human body's parameter of human object；
Correspondingly, the property parameters of feature based parameter adjustment project content, are specifically as follows：Based on characteristics of human body's parameter
Adjust the property parameters of project content.
It is well known that there are many having for the feature of human object.And in the present invention, it is special based on the corresponding human body of different characteristic
Sign parameter also differs the adjustment mode that project content is adjusted.
In a kind of specific application scenarios, the human body complexion of different people is not quite similar, and is exported for existing projection
For method, wearable electronic equipment can project to project content on human object according to pre-set parameter.But
It is that, when the color of human body complexion and project content is closer to, if the colour of skin is partially black, the font of project content also inclined black will
The project content being shown on human object can be caused unintelligible, to influence user's viewing.In this case, in the prior art
In, user can only be adjusted manually, inconvenient and cumbersome.
Based on the problem, the embodiment of the present invention three discloses a kind of projection output method and is obtained unlike embodiment two
Take with the relevant characteristics of human body's parameter of human object, be specifically as follows：Image is handled, the first face of human object is obtained
Color parameter value；
Wherein, which is specially the image for human object that detection module is captured；As detection module can be
Image capture module can collect the image for human object.
It should be noted that handling image, the specific implementation of the first color parameter value of human object is obtained
In the present invention, there is no limit.RGB processing modes such as may be used to handle image, correspondingly, the first color parameter value
May include three kinds of parameters, respectively and R (red) corresponding parameter value, parameter value corresponding with G (green) and and B
(blue) corresponding parameter value.
Correspondingly, as shown in Fig. 2, the property parameters based on characteristics of human body's parameter adjustment project content, may include following
Step：
Step 2031：Obtain the second color parameter value of project content；
Wherein, the second color parameter value of acquired project content is corresponding with the first color parameter value, such as the first color
Parameter value includes three kinds of parameters, correspondingly, the second acquired color parameter value also includes three kinds of parameters.
And when the first color parameter value only includes a kind of parameter that can characterize human body complexion, correspondingly, identified
Second color parameter value of project content also only includes a kind of parameter, is such as hexadecimal color parameter.
Step 2032：First color parameter value and the second color parameter value are compared, determine the first color parameter value
With the difference value of the second color parameter value；
By comparing the first color parameter value with the second color parameter, human body complexion and project content can determine
Color whether be closer to；It is and specific, it may be determined that the difference value of the first color parameter value and the second color parameter value.
Step 2033：Judge whether difference value is less than or equal to predetermined threshold value；
Wherein, threshold value can be set in advance in wearable electronic equipment, can also be supported to make by oneself by default
Justice.
Whether threshold value is to judge the display color of human body complexion and project content close to (such as whether belonging to a series of face
Color) standard；When difference value is more than predetermined threshold value, illustrate that the display color of human body complexion and project content is kept off, then,
The project content shown on human object can be watched than more visible convenient for user.And when difference value is less than or equal to predetermined threshold value
When, illustrate that the display color of human body complexion and project content is closer to, then, it will lead to the projection shown in human object
Content is unintelligible, at this point, then needing to be adjusted the display color of project content.
Step 2034：When determining that difference value is less than or equal to threshold value, the second color parameter value is adjusted, so that difference value is big
In threshold value.
Wherein, the adjusting range of the second color parameter value does not limit in the present invention, the difference value after ensureing to adjust
It, can expansion difference value appropriate on the basis of threshold value.Such as adjust the second color parameter value so that difference value is bigger than threshold value
50%.
In the present embodiment, by adjusting the second color parameter value so that the first color value and the second color parameter value it
Between difference value be more than threshold value, to ensure that project content can clearly indicate on human object.
In another specific application scenarios, the size or shape of the same human body parts of different people may not phases
Together；As the size of the palm of different people may and differ.And a certain human body parts of same people are presented under different postures
Size or shape may also and it is identical, be all different with size and shape of the hand when the five fingers are stretched out such as hand when clenching fist.That
, for existing projection output method, wearable electronic equipment can be according to pre-set parameter by project content
It projects on human object.But when the size or shape of the size of human object or shape and project content mismatch, very
Being susceptible to part project content cannot project on human object；Or project content occur and cross less than human object, it is beautiful
Spend the problems such as poor.In this case, in the prior art, user can only be adjusted manually, inconvenient and cumbersome.
Based on the problem, the embodiment of the present invention four discloses a kind of projection output method, unlike embodiment two, this
In embodiment, acquisition and the relevant characteristics of human body's parameter of human object can specifically include：
A1：Determine the first area of human object；
The first area of human object is the region for showing project content.And determine the mode of first area in this hair
Bright there is no restrictions, such as detection module to be used to capture the image of human object, and then is handled by image, it may be determined that people
It is first area that the profile of body object, which is formed by region,.
A2：Obtain relevant first parameter of feature with first area；
The feature of first area at least may include shape or size, and the first parameter is the shape or size with first area
Relevant parameter.
By taking the feature of first area includes shape as an example, it is that coordinate is former that can specifically choose the certain point on first area
Point, to establish reference axis, multiple coordinate points on profile to obtain first area are the first parameter.
By taking the feature of first area includes size as an example, the area parameters of first area can be specifically obtained.
Correspondingly, the property parameters based on characteristics of human body's parameter adjustment project content, including：
B1：Obtain relevant second parameter of feature with project content；
Wherein, the feature of project content can be corresponding with the feature of first area；Specifically, the feature of project content can be with
Consistent with the feature of first area, for example, when the first parameter is parameter relevant with the shape of first area, the second parameter can
Think the shape relevant parameter with project content；And when the first parameter is parameter relevant with the size of first area, second
Parameter can be the relevant parameter of size with project content.Certainly, the feature of project content can also be with the spy of first area
Relevant feature is levied, e.g., when the first parameter is with the shape of first area or the relevant parameter of size, the second parameter can be
The projection angle of project content.
B2：Based on first the second parameter of parameter adjustment, so that projection output module can be by the project content after adjustment
It projects in first area；
It is emphasized that the adjustment mode for the second parameter does not limit in the present invention；
As a kind of realization method, it is based on first the second parameter of parameter adjustment, is specifically as follows：Adjust the throwing of project content
Shadow angle；
Wherein, unmatched in the first parameter and the second parameter, it can be by adjusting projection angle, to throw
Project content after adjustment can be become projecting to the second area to be projected by shadow output module from the first region to be projected is projected to
Domain.
It should be noted that can have the first area of human object under the first region to be projected, and the second area to be projected
Another region that can be with human object under domain or another human object.Such as the human object under the first region to be projected
It can be by adjusting the projection angle of project content when determining that the size of hand is less than the size of project content for hand so that throw
Shadow output module can project to project content after adjustment on arm.Or such as, the human object under the first region to be projected
It can be by adjusting the throwing of project content when determining that the length of thumb is less than the length of project content for the thumb of hand
Shadow angle so that projection output module can project the project content after adjustment on middle finger in one's hands.
As another realization method, it is based on first the second parameter of parameter adjustment, is specifically as follows：Adjust project content
Projected size, so that projection output module projects to the project content after adjustment completely on the first area of human object.
Specifically, when the size of the size of first area and project content mismatches, as the size of project content is more than
The size of first area or the size of project content cross the size less than first area, can be big to the projection of project content
It is small to be adjusted, it is matched with first area with the project content after ensureing the adjustment of projection output module output.
Certainly, the present invention is not limited in both realization methods, and for another example, the first parameter and the second parameter are and shape
Relevant parameter, then can be by adjusting the second parameter so that the shape of project content and the shape of first area match.
Based on example IV, in practical applications, the variation of the posture of human object can cause first area to change,
As hand becomes the posture that the five fingers are stretched out from the posture clenched fist.So, the project content of projection output module output may cannot
It projects on human object completely.Based on the problem, the embodiment of the present invention five discloses a kind of projection output method, such as Fig. 3 institutes
Show, this method may comprise steps of：
Step 301：When receiving the first operation of user, the human body pair in drop shadow spread is captured using detection module

Step 306：When the view field of human object becomes second area from first area, obtain and second area
The relevant third parameter of feature；
Specifically, can be with the human object in real-time capture drop shadow spread, when human object using detection module
When view field changes, the relevant third parameter of feature of the second area after can obtaining and changing.
Wherein, consistent with example IV, the feature of second area at least may include shape or size.
If human object is hand, when hand becomes from the posture clenched fist the posture that the five fingers are stretched out, it can obtain and be stretched with the five fingers
The relevant third parameter of characteristic of hand after opening.
Step 307：Based on the second parameter of third parameter adjustment；
Specific adjustment mode is consistent with the adjustment mode described in example IV, and details are not described herein.
Step 308：Control projection output module exports the project content after adjustment on the human object after variation.
