In this technical scheme, because when Same Scene is carried out Image Acquisition, such as using the camera on the terminal to obtain, because existing, the distance between camera and this scene changes, thereby in the image that obtains, the displaying ratio of Same Scene also can there are differences, therefore, first the ratio of image is regulated before by image being synthesized process, to reach better synthetic effect.In building-up process, need to identify the Same Scene in the different images, there is more method in the prior art in this, such as by after the gray scale of image is processed, carries out the judgement of grey scale change, or different images is compared and judgement etc.
Fig. 3 A to Fig. 3 F shows the according to an embodiment of the invention synoptic diagram of image processing method.
As shown in Figure 3A, use 300 pairs of objects 302 of terminal to carry out Image Acquisition from different angles respectively, the subject image when obtaining different angles.In Fig. 3 A, from 8 angles such as A, B, C, this object 302 has been carried out respectively Image Acquisition.Terminal 300 is when carrying out Image Acquisition, the rotation of self can occur, thereby so that every image is all corresponding to an angle, and these angles can be used for all images that obtain are arranged (object 302 of Fig. 3 A also can be regarded the combination that is joined end to end and consisted of by many images as, but in fact not necessarily really carries out the combination of image).Therefore, when carrying out Image Acquisition, terminal 300 records the terminal angle corresponding to this image simultaneously at every turn, and terminal angle and correspondence image are carried out association store.Above-mentioned 8 images that obtain, can be used as one group of image for object 302, when the user when terminal 300 is watched this group image, can view the object 302 of different angles, such as carrying out the terminal angle of above-mentioned image when taking end to end, form the column structure among Fig. 3 A, then rotate this column structure by the user, so that show the image of all angles.
Certainly, except image is carried out end to end after, carry out hand rotation by the user, can also adopt other the form of checking, shown in Fig. 3 B.
In Fig. 3 B, by rotating terminal 300, make terminal 300 obtain real-time rotational angle, and the rotational angle of this real-time rotational angle when being acquired with every image is corresponding, particularly, under less rotation, just can cover whole angles (0 ° to 360 °), such as can be so that during 1 ° of terminal 300 actual rotation, corresponding to 10 ° in the image.So, just can automatically play corresponding image according to the angle of terminal 300.
Perhaps, also can be in navigation process, after the real-time rotational angle of terminal 300 obtained, when this real-time rotational angle is in certain preset range, screen in terminal 300 shows corresponding image, and does not produce the effect of the column structure among Fig. 3 B.
By the way, can realize actual many images that obtain are stored and browsed, but be merely able to form the column structure among similar Fig. 3 A, Fig. 3 B or only demonstrate many images that photograph, for the user, that the experience that obtains is interrupted often, discontinuous.This is because when carrying out Image Acquisition, the reasons such as storage space owing to terminal 300 self, can't obtain angled image, so that in navigation process, always exist and the real-time rotational angle of terminal 300 image one to one, it is synthetic then can to utilize this moment a plurality of images to carry out realtime graphic.
Particularly, shown in Fig. 3 C, to the image browsing on the terminal 300 time, there is direction of observation 304, this direction is a directions, be in original state (such as the demonstration of image will be carried out the time such as being set as in terminal 300, or can physical button be set in terminal 300, when this physical button is operated, terminal 300 all enters original state) time, straight line perpendicular to terminal screen, sensing screen is direction of observation 304, and when terminal 300 was rotated, this direction of observation 304 did not change.
Certainly, direction of observation 304 also can be for passing the direction of screen, and image direction 306 also can be the direction of pointing to image, as long as the direction of direction that can each image is corresponding and each image and the relation between the direction of observation 304 are distinguished.
Therefore, after terminal 300 turns to a certain position, have two kinds of situations, in the first situation, direction of observation 304 overlaps with some image directions 306, then demonstrates this image in terminal 300 and gets final product; In the second situation, direction of observation 304 is between certain two image direction 306, then can carry out the synthetic of realtime graphic by corresponding two images.
Particularly, for the second situation, in Fig. 3 C, there are the first image direction 306A, the second image direction 306B and the 3rd image direction 306C, and direction of observation 304 is between the first image direction 306A and the second image direction 306B, and the image that does not have other between the first image direction 306A and the second image direction 306B then carries out the synthetic of realtime graphic by the first image direction 306A corresponding the first image 308A and the second image 308B corresponding to the second image direction 306B.
Utilize V=V1 * cos α+V2 * cos β to synthesize realtime graphic, wherein, V is the display attribute value of realtime graphic, V1 is the display attribute value of the first image 308A, V2 is the display attribute value of the second image 308B, α is the angle of direction of observation 304 and the first image 308A, and β is the angle of direction of observation 304 and the second image 308B.The display attribute value here can be the pixel value of image, the color of each pixel (such as rgb value, YUV value etc.), colour temperature etc.Can obtain realtime graphic when arbitrarily angled by above processing, thereby so that the user in the process of rotating terminal 300, realizes seamlessly transitting at the image that terminal 300 demonstrates, promote visual effect.
In addition, because terminal 300 when object 302 is carried out the Image Acquisition of different angles, can't accomplish all to equate with the distance of object 302, so that in different images at every turn, the displaying ratio of object 302 is not identical, thereby causes impact effect when carrying out realtime graphic synthetic.
Suppose the first image 308A shown in Fig. 3 D, and the second image 308B is shown in Fig. 3 E, then obviously there is larger difference in both displaying ratios.And for terminal 300, before the judgement to displaying ratio, at first need the target object in each image is identified, and the mode of identification can be by a variety of, in a kind of situation, can be by after image being carried out the gray scale processing, variation according to gray-scale value identifies destination object, and because two images are to take continuously, thereby the attitude of the destination object that identifies is close, is easy to recognize be same destination object.So, the displaying ratio of the second image 308B can be adjusted to the state shown in Fig. 3 F, so that the first image 308A has similar displaying ratio with the second image 308B.Certainly, also can regulate the displaying ratio of the first image 308A, or according to user's setting, simultaneously the displaying ratio of the first image 308A and the second image 308B is adjusted to identical, appropriate ratio.
More than be described with reference to the accompanying drawings technical scheme of the present invention, considered that the ways of presentation for photo is single in the correlation technique.Therefore, the present invention proposes a kind of terminal and a kind of image processing method, can realize the multi-angle of reference object is showed and watched, promote the user and experience.
In the present invention, term " a plurality of " refers to two or more, unless clear and definite restriction is arranged in addition.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
