Fig. 2 shows the flow chart for the method for displaying image that one specific embodiment of the present invention provides.The present embodiment is main
In scene applied to family's monitoring, for example, camera is placed in the parlor in user family, the sand being aligned among parlor
Hair, to photograph the child just to be played on sofa, and by the mobile device of the transmission of video images photographed to parent,
Parent is set to find the dangerous situation in family in time.Therefore, the original image in the present embodiment is the image of camera shooting,
In the present embodiment, it is necessary to which the original image is included on the display screen of mobile terminal (such as mobile phone, tablet personal computer).Such as figure
Shown in 2, this method comprises the following steps：
Step S210：In advance on the display screen of mobile terminal setting screen viewing area size and location.
In this example it is shown that screen is applied not only to display image, it is additionally operable to show some control information.Therefore, it is necessary to
On-screen display (osd) area for display image and the screen for display control information are preset according to the size of display screen
The size and location of control area.For example, above display screen 2/3rds regional area can be arranged to screen display area
Domain, below display screen remaining 1/3rd regional area is arranged to screen control region.Wherein, on-screen display (osd) area is complete
Portion is used for display image, i.e.,：Image takes on-screen display (osd) area, its edge is not blanked part.Screen control region shows
The control information shown can include but is not limited to：Angle information, control camera direction of rotation and/or the regulation shooting of camera
Button of head definition etc..
Those skilled in the art can set to on-screen display (osd) area and the specific of screen control region according to the actual requirements
The mode of putting carries out various settings, and this is not limited by the present invention.
Step S220：Place is zoomed in and out to original image according to the size of original image and the size of on-screen display (osd) area
Reason, make the size and the chi of on-screen display (osd) area in the vertical direction of zoomed image (image after handling) in the vertical direction
It is very little identical, and the size of zoomed image in the horizontal direction is more than the size of on-screen display (osd) area in the horizontal direction.
In this step, first have to determine the size of original image and the size of on-screen display (osd) area, then will be original
Image is adapted in one direction with on-screen display (osd) area.For example, the size of original image is 1280*720, screen display
The size in region is 920*720, i.e.,：The height 720 of original image in the vertical direction is with on-screen display (osd) area in vertical direction
On height 720 it is identical, and the width 1280 of original image in the horizontal direction be more than on-screen display (osd) area in the horizontal direction
Width 920, therefore, when being zoomed in and out to original image, pantograph ratio is arranged to 1：1, i.e. zoomed image and original image
Size it is identical.And for example, the size of original image is 1280*720, and the size of on-screen display (osd) area is 1250*1080, in order that
The height 720 of zoomed image in the vertical direction is identical with the height 1080 of on-screen display (osd) area in the vertical direction, it is necessary to will
Pantograph ratio is arranged to 1.5：1, therefore, original image is amplified the zoomed image that size is 1920*1080 is obtained after 1.5 times, should
The height of zoomed image in the vertical direction is identical with the height of on-screen display (osd) area in the vertical direction (being 1080), and should
The width 1920 of zoomed image in the horizontal direction is more than the width 1250 of on-screen display (osd) area in the horizontal direction.In addition,
When performing scaling processing, in order that the Aspect Ratio of image keeps constant, it is preferable that make the pantograph ratio of image in a first direction
Example is identical with the scaling in second direction.
For the ease of transmission, the image pixel of usual camera shooting is all relatively low, therefore, if setting very pantograph ratio
Greatly, the image after amplification can be made very fuzzy；And if pantograph ratio is set to obtain into very little, the image after diminution can be made to be less susceptible to distinguish
Know.Therefore, in a preferred embodiment of the invention, the size phase of on-screen display (osd) area and original image in the vertical direction is made
Together, thus pantograph ratio be 1：1, now, zoomed image is original image, so as to farthest ensure definition, both
It will not cause to obscure because of amplification, will not also cause to be not easy to recognize because of diminution.Preferably, on-screen display (osd) area and original image
The size of in the vertical direction is more or less the same, thus only needs slightly to scale original image.
Step S230：According to the wide-angle parameter of camera and the size of zoomed image, the pixel position of zoomed image is calculated
Put the mapping relations between shooting angle.
Because camera has certain image pickup scope, its image shot only includes the scenery within image pickup scope, and right
Scenery outside image pickup scope can not then photograph.Therefore, just comprising within camera image pickup scope in zoomed image
Scene, according to the size of zoomed image and the image pickup scope of camera, it is possible to by the specific location of pixels on zoomed image
Correspond with the shooting angle of camera.
For example, the shooting angle of camera in the horizontal direction is 0-100 degree, the shooting angle of in the vertical direction is 0-
90 degree, and the size of zoomed image in the horizontal direction is 1280, the size of in the vertical direction is 720.With zoomed image
The lower left corner is that the origin of coordinates establishes reference axis, then the coordinate in the zoomed image lower left corner is (0,0), the coordinate in the lower right corner (1280,
0), the coordinate in the upper left corner is (0,720), and the coordinate in the upper right corner is (1280,720).Assuming that zoomed image lower-left angular coordinate for (0,
0) the horizontal shooting angle corresponding to pixel is 0, and vertical shooting angle is also 0；Bottom right angular coordinate is the picture of (1280,0)
Horizontal shooting angle corresponding to vegetarian refreshments is 100, and vertical shooting angle is 0；The picture that coordinate is (640,0) can correspondingly be determined
Horizontal shooting angle corresponding to vegetarian refreshments is 50, and vertical shooting angle is 0.Assuming that zoomed image top left co-ordinate is (0,720)
Pixel corresponding to horizontal shooting angle be 0, vertical shooting angle be 90；Upper right angular coordinate is the pixel of (1280,720)
The corresponding horizontal shooting angle of point is 100, and vertical shooting angle is 90；It can correspondingly determine coordinate for (640,360)
Horizontal shooting angle corresponding to pixel is 50, and vertical shooting angle is 45.The rest may be inferred, can will be every on zoomed image
The shooting angle of one pixel and camera corresponds.
Step S240：Zoomed image is included in on-screen display (osd) area；Also, determine zoomed image in the horizontal direction
Mapping relations between the local pixel content and camera shooting angle of display, and corresponding display and the local pixel content pair
The shooting angle answered.
Due to the size (720) and the size one of on-screen display (osd) area in the vertical direction of zoomed image in the vertical direction
Cause, and the size (1280) of zoomed image in the horizontal direction is more than the size (920) of on-screen display (osd) area in the horizontal direction,
Therefore, the pixel content of zoomed image in the vertical direction, i.e., vertical coordinate can all be shown from 0 to 720 pixel；And
The pixel content of zoomed image in the horizontal direction, i.e. horizontal coordinate then can not all show from 0 to 1280 pixel, can only
920 pixels on horizontal coordinate line are shown, remaining 360 pixel can not then be shown.
For example, the image shown in Fig. 3 a is zoomed image, Fig. 3 b black box is on-screen display (osd) area, then black box
Interior image is the partial content of zoomed image shown on on-screen display (osd) area.It is still assumed that Fig. 3 a picture size is
1280*720, and establish coordinate system by the origin of coordinates of the lower left corner of image, then it is as can be seen that shown on on-screen display (osd) area
The vertical coordinate range of parts of images be 0-720, i.e. in the vertical direction shows whole pixel contents of zoomed image；Screen
The horizontal coordinate scope of shown parts of images is 200-1120 on curtain viewing area, and horizontal coordinate is less than 200 and water
Two parts pixel content of the flat coordinate more than 1120 is not shown then, i.e., only show the office of zoomed image in the horizontal direction
Portion's pixel content.
In this example, when the image after display processing, by the center alignment at the center of image and viewing area.Namely
Say, zoomed image local pixel content shown in the horizontal direction is the center section of image, the water corresponding to the part
Flat shooting angle scope is 15.6 degree of -87.5 degree, therefore, the local pixel content can be correspondingly shown in screen control region
In each pixel corresponding to shooting angle, so that user understands the image that is currently seen is which portion in general image
Point, the image for also having which angle is not shown, so as to simulate the sensation of true environment for user.In this example with
Illustrated in horizontal direction exemplified by the center section of acquiescence display image, because the people of user's concern or thing are past under normal circumstances
Toward the center section for being located at image, and the both sides of image are often some inessential backgrounds, therefore are write from memory in step S240
Recognize the center section of display image.Certainly, the left side of display image can also be given tacit consent in the horizontal direction in step S240
Point or right part, or, viewing area in the horizontal direction can also be determined according to the setting of user.
Step S250：According to the slip instruction received, display scaling is slided in the horizontal direction in on-screen display (osd) area
The rest of pixels content of image；Also, the mapping relations between rest of pixels content and camera shooting angle are determined, and correspondingly
Display shooting angle corresponding with rest of pixels content.
Wherein, slip instruction can be sent in several ways.For example, slip instruction can pass through touching display screen
The slide displacement amount of input, now, user need to only be slided on a display screen with finger, and zoomed image will be slided along user's finger
Dynamic direction movement, so as to not shown rest of pixels content before showing.Or slip instruction can also pass through sensing
The mobile displacement for the display screen that device detects, now, user only need to move mobile phone in the horizontal direction, it becomes possible to show contracting
Put the rest of pixels content of image in the corresponding direction.
Specifically, it is first when sliding the rest of pixels content for showing zoomed image in the horizontal direction in on-screen display (osd) area
First need to calculate the displacement component of above-mentioned slide displacement amount or mobile displacement in the horizontal direction, then according to the displacement component
Direction and size slide show zoomed image rest of pixels content.For example, when slip instruction is to pass through touching display screen
During the slide displacement amount of input, if user's finger level slides 1 centimetre to the left, zoomed image level will be also moved to the left therewith
1 centimetre, so that the horizontal coordinate scope change of the parts of images of display is 201-1121 in on-screen display (osd) area；If user
Finger slides straight up, because its displacement component of caused slide displacement amount in the horizontal direction is 0, thus zoomed image
It is not moved, the picture material of display is constant in on-screen display (osd) area.Similarly, when slip instruction is to be detected by sensor
Display screen mobile displacement when, if mobile phone level is moved to the left 1 centimetre by user, will make to show in on-screen display (osd) area
The horizontal coordinate scope change of parts of images be 199-1119；If user moves mobile phone straight up, due to its generation
Mobile displacement displacement component in the horizontal direction be 0, thus in on-screen display (osd) area display picture material it is constant.
In addition, when zoomed image is moved according to slip instruction, also to determine whether that zoomed image is being waited to show
Whether remaining part is less than the displacement in slip instruction on the direction shown, and if the determination result is YES, zoomed image is existed
On direction to be shown remaining part all show after then no longer respond user input to this direction move
Slip instruction.For example, it is assumed that not shown part is also surplus 1 centimetre on the left of zoomed image, and need to scale according to slip instruction
Image moves right 2 centimetres, now zoomed image need to only move right 1 centimetre, makes part remaining on the left of zoomed image
All show, refer to if now further receiving the slip for needing to move right zoomed image that user sends
Order, then no longer respond the instruction.
As can be seen here, after slip instruction is received, shown picture material only can be along level in on-screen display (osd) area
Direction is moved, and in the vertical direction will not be moved, consequently facilitating user finds the certain content of its concern.Also, when aobvious
After the picture material change shown, it is shown in screen control region also will be corresponding to the camera angle that picture material is corresponding
Change, be which part in general image thus, it is possible to the image for recognizing user currently to show, be user this to where to
Further slide image and provide reference.
In the above-described embodiments, original image is adapted to on-screen display (osd) area in the vertical direction, it is vertical to obtain
The zoomed image that direction can all be shown, its remaining part of zoomed image is then shown by sliding type in the horizontal direction
Point.Specifically, in display image, it is necessary to zoomed image perform decoding, render and the sequence of operations such as draw, wherein,
Whole pixel contents in zoomed image all are rendered out, to show which parts of images just to the pixel of appropriate section
Content is drawn, when the image section to be shown changes, then the partial pixel content after corresponding drafting changes.
Image in above-described embodiment both can be still image or dynamic image, can also be by some frames
The video that consecutive image is formed.
In addition, in other examples, original image can also be carried out in the horizontal direction with on-screen display (osd) area
Adaptation, obtains the zoomed image that horizontal direction can all be shown, then in the vertical direction shows contracting by sliding type
Put the remainder of image.For example, it is assumed that the size of original image is 720*5600, due to original image in the vertical direction
Size is larger, image very little can be caused if in the vertical direction is adapted to, and can leave blank in the horizontal direction
Region, at this point it is possible to which original image is adapted in the horizontal direction with on-screen display (osd) area, obtaining horizontal direction can be complete
The zoomed image that portion is shown, then in the vertical direction the remainder of zoomed image is shown by sliding type.It is specific real
Shi Shi, the dimension scale of original image and the dimension scale of on-screen display (osd) area can be combined to determine to enter in which direction
Row adaptation.
