Accompanying drawing 1 is referred to, is the reality for the method taken pictures using different angle of visual field cameras that the embodiment of the present invention one provides Existing flow, its executive agent can be the terminal with camera, for example, the intelligent terminal such as smart mobile phone, tablet personal computer.Accompanying drawing The method taken pictures using different angle of visual field cameras of 1 example mainly includes the following steps that S101 to step S103：
S101, judge that user currently requires the multiple of imaging amplification.
In embodiments of the present invention, user currently requires that the multiple of imaging amplification is actually also that it operates intelligence before shooting During the camera functions of intelligent terminal such as energy mobile phone, the multiplication factor of photo is intentionally got by digital zoom.
Existing intelligent terminal has touch-screen, and in user using camera function and when having digital zoom demand, its is general It is to be realized by sliding finger on the touchscreen.Because the different glide directions of finger represent different zoom operations, therefore, Judge user currently require imaging amplification multiple before, it is necessary to judge amplification or reduction operation.Specifically, in the present invention In one embodiment, judge that user currently requires that the multiple of imaging amplification comprises the following steps S1011 to step S1013：
S1011, judge that user currently requires that imaging is amplification or diminution.
As it was previously stated, the different glide directions representative of user's finger on the touchscreen is different zoom operations.At this In inventive embodiments, judge that user currently requires that imaging is that a kind of method of amplification or diminution is：
S1, glide direction of the detection user's finger on the screen of the affiliated terminal of camera.
It can be specifically the position for recording user's finger on the screen of the affiliated terminal of camera, be determined according to position relationship Glide direction.
S2, if glide direction is finger leave the affiliated terminal of camera screen central point, it is determined that user currently will It seems amplification to hope for success.
S3, if glide direction is central point of the finger close to the screen of the affiliated terminal of camera, it is determined that user currently will Hope for success seems to reduce.
In the embodiment of the present invention, can by doing a definition in program, for example, for before and after finger twice in screen position The distance with center's point of screen is put, if before regulation once after the distance of screen position and center's point of screen is less than once in screen Position and center's point of screen apart from when user currently require that imaging is amplification, then when detecting that glide direction is that finger leaves and taken the photograph As belonging to head during the central point of the screen of terminal, determine that user currently requires that imaging is amplification.Conversely, for before and after finger two It is secondary in screen position and the distance of center's point of screen, if before regulation once after the distance of screen position and center's point of screen is more than Once screen position and center's point of screen apart from when user currently require that imaging is to reduce, then when detecting that glide direction is When finger is close to the central point of the screen of the affiliated terminal of camera, determine that user currently requires that imaging is to reduce.
S1012, if judging, user currently requires that imaging is amplification, calculates user's finger when performing amplifieroperation and is taking the photograph The screen sliding distance of terminal as belonging to head.
S1013, according to finger in the screen sliding distance of the affiliated terminal of camera and the relation of imaging multiplication factor, it is determined that User currently requires the multiple of imaging amplification.
For example, if finger is with the corresponding relation for being imaged multiplication factor in the screen sliding distance of the affiliated terminal of camera： If finger is 0.2 times in the screen sliding distance 0.1cm of the affiliated terminal of camera, imaging multiplication factor, then use is being detected Family finger determines that user currently requires the multiple of imaging amplification when the screen sliding distance of the affiliated terminal of camera is 0.1cm For 0.2 times.It is of course also possible to screen sliding distance and imaging multiplication factor structure of the finger in the affiliated terminal of camera are provided in advance Into some specific function, then, when detecting user's finger in the screen sliding distance of the affiliated terminal of camera, by this Variable of the distance as the function, the multiple that user currently requires imaging amplification is also can obtain after input.
S102, the multiple and the relation of multiple threshold value of imaging amplification are currently required according to user, the different angles of visual field is enabled and takes the photograph As a camera in head is shot.
In image processing field, the angle of visual field is using the camera lens of optical instrument as summit, can be passed through with the image of measured target The angle that two edges of the maximum magnitude of camera lens are formed.The size of the angle of visual field determines the field range of optical instrument, that is, regards Rink corner is bigger, and the visual field is bigger, and optical power is with regard to smaller.Generally, target object, which exceedes this angle, would not be received in mirror In front.Usually, the angle of visual field is bigger, and focal length is shorter.
Any one camera, its so-called digital zoom all has the upper limit, once the multiple of digital zoom or right The user answered currently requires that the multiple of imaging amplification has exceeded this upper limit, and image will thicken unclear.Of the invention real Apply in example, a multiple threshold value can be set, the multiple threshold value can be that the angle of visual field is relatively large in different angle of visual field cameras Multiplication factor maximum of the camera in imaging clearly, that is to say, that user currently requires that the multiple of imaging amplification exceedes This multiple threshold value, obtained photo are not clearly.
In an embodiment of the invention, different angle of visual field cameras include the first camera and second camera, described The angle of visual field of first camera is more than the angle of visual field of the second camera, wherein, imaging amplification is currently required according to user The relation of multiple and multiple threshold value, enabling a camera in different angle of visual field cameras and carrying out shooting to be：If user It is required that the multiple of imaging amplification is not more than multiple threshold value, then enables the first camera and shot, if the user requires imaging The multiple of amplification is more than multiple threshold value, then enables second camera and shot, and herein, the angle of visual field of the first camera is more than the The angle of visual field of two cameras.
For example, it is assumed that multiple threshold value is 2 times, if user requires that the multiple of imaging amplification is not more than multiple threshold value for 1 times, The first larger camera of the angle of visual field is then enabled, for example, the camera that the angle of visual field is 80 ° is shot；If user requires imaging The multiple of amplification is 4 times and is more than multiple threshold value, then enables the less second camera of the angle of visual field, for example, the angle of visual field is 40 ° Camera is shot.
S103, step S102 is shot after gained photo carries out digital zoom and exported.
It was found from the method taken pictures using different angle of visual field cameras of the above-mentioned example of accompanying drawing 1, pass through institute with prior art The digital zoom of meaning is merely cut out to image and/or amplifies difference, and the present invention is currently to be required to be imaged according to user The multiple of amplification and the relation of multiple threshold value, the camera enabled in different angle of visual field cameras are shot, Ran Houzai Digital zoom is carried out to the photo of the shooting.Because the angle of visual field of camera is different, its obtained image definition is different, because This, when selecting the camera of different visual angles to shoot the difference of photo multiplication factor according to user, photo image quality is preferable, can To obtain the higher photo of quality.
