Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, a method for focusing after photographing according to a preferred embodiment of the present invention includes the following steps:
and S100, starting a camera by the mobile terminal to enter a photographing preview picture, and detecting whether the mobile terminal shakes through an acceleration sensor.
Specifically, when the mobile terminal (e.g., a mobile phone) taking a picture shakes, the image in the picture moves along with the mobile terminal, but the distance of the picture corresponding to the movement of the image is different for objects at different distances from the mobile terminal. For example, the farther the object is from the mobile phone, the smaller the screen distance of the corresponding screen image, and conversely, the closer the object is to the mobile phone, the larger the screen distance of the corresponding screen image. According to the invention, after the mobile terminal starts the camera to enter the shooting preview picture, whether the mobile terminal shakes or not is detected through the acceleration sensor, an acceleration threshold value can be preset, and the detected acceleration is compared with the threshold value, and when the detected acceleration is greater than the preset threshold value, the mobile terminal shakes, so that corresponding processing is conveniently carried out on objects in the shaken picture.
Further, the step S100 specifically includes:
s101, the mobile terminal starts a camera to enter a photographing preview picture;
s102, the mobile terminal controls an acceleration sensor to detect whether the mobile terminal shakes every other preset time when the mobile terminal photographs the preview picture;
s103, judging that the mobile terminal shakes when the detected acceleration is larger than a preset threshold value;
and S104, when the shaking of the mobile terminal is not detected, continuing to execute the step S102.
And S200, when the mobile terminal is detected to shake, calculating the distances between all objects in the photographing preview picture and the mobile terminal, focusing and photographing each object with different distances once, and storing all pictures.
Specifically, when the mobile terminal is detected to shake, the front-back relation of the picture object is calculated and judged by combining the image analysis module through the shaking of the picture. The image analysis module calculates that the image of the picture is divided into m picture depth distances of D1 and D2 … Dm from near to far. The depth distance of each picture needs to be focused once and photographed and imaged once. (wherein, the depth distance of one frame may include 1 or more than 1 object, which means that the actual distances from the several objects to the camera are the same and are all in the same depth distance of the frame); for example, when the mobile phone triggers to take a picture, the mobile phone enters a photographing module, and performs focusing and photographing imaging respectively according to the calculated depth distances of the m pictures, and the images are stored as pictures S1 and S2 … Sm respectively.
Further, the step S200 specifically includes:
s201, when the mobile terminal is detected to shake, calculating and judging the front-back position relation of an object in a preview picture;
s202, calculating the depth distances of m frames of the object images D1 and D2 … Dm from near to far in the preview frame;
s203, respectively carrying out primary focusing and photographing imaging according to the calculated depth distances of the m pictures, and respectively saving the pictures as pictures S1 and S2 … Sm.
When the mobile phone shakes, the images in the pictures can move along with the mobile phone, but the picture distances of the corresponding images are different from the objects with different distances from the equipment. The farther the object is from the mobile phone, the smaller the picture distance of the corresponding picture image, and conversely, the closer the object is to the mobile phone, the larger the picture distance of the corresponding picture image. The picture distance unit moved here can be described in pixels, i.e. how much the picture image has moved by the pixel distance.
In the shaking process of the mobile phone, the pixel distance Ln of any pixel Pn (px, py) of the image moving in the shaking process of the mobile phone is analyzed. The greater the pixel distance moved, the closer the object is to the camera. Each image pixel on the whole picture is classified according to the distance of the moving pixel, and the image pixel can be divided into m picture depth distances (D1 and D2 … Dm) from near to far, and the attribution depth of each pixel is recorded at the same time. Because an object is composed of a plurality of pixels, the pixels move the same pixel distance in the shaking process of the mobile phone and can be classified into a depth distance, so m is far smaller than n, wherein the total number of pixels of n-bit images is, and m is the total number of the depth distances of the picture.
And step S300, when the mobile terminal detects that the user touches the first picture, replacing the current picture with the picture matched with the touch coordinate from the stored pictures according to the corresponding relation between the touch coordinate and the pixel coordinate.
Specifically, after the photographing is completed, the user enters the gallery, clicks the preview widget after the photographing is completed, and the display screen displays the first picture, i.e., S1. Judging whether the touch screen has touch operation through the touch module, if so, receiving the specific touch coordinate, wherein the touch coordinate and the pixel coordinate of the image have one-to-one correspondence, and according to the correspondence, positioning the pixel coordinate of the picture corresponding to the current touch coordinate T (x, y) to be P (Px, Py). according to the obtained pixel coordinate corresponding to the touch coordinate, assuming that the pixel is in the 3 rd picture depth distance through the previous image analysis module, the display picture is a picture S3 shot by the 3 rd picture depth at the moment, and replacing the previous picture S1.
Similarly, by the method, a user clicks a coordinate on the screen at will, an image pixel coordinate P (Px, Py) is correspondingly obtained on the image, and the pixel finds the corresponding h (1 = < h < = m) picture depth distance in the result processed by the image analysis module, so that the image Sh replaces the previous display picture.
Further, the step S300 specifically includes:
s301, after the mobile terminal finishes photographing, displaying a first picture on a display screen;
s302, the mobile terminal detects whether touch operation of a user on a first picture exists;
s303, when a touch operation is detected, receiving a specific coordinate of the touch operation, and positioning a pixel coordinate of a picture corresponding to the current touch coordinate T (x, y) to be P (Px, Py) by a touch seat according to the corresponding relation between the touch coordinate and the pixel coordinate;
and S304, if the picture of the touch coordinate matched from the pictures stored as S1 and S2 … Sm is Sh, controlling Sh to replace S1 according to the pixel coordinate P (Px, Py) of the picture corresponding to the current touch coordinate T (x, y), wherein 1= < h < = m.
