Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
Referring to fig. 1, a flowchart illustrating steps of a method for capturing a moving image according to a first embodiment of the present invention is shown.
The dynamic image shooting method of the embodiment of the invention comprises the following steps:
step 101: a change in distance between the finger touch point and the photographing button is detected in the detection area.
The dynamic image shooting method in the embodiment of the invention is applied to the mobile terminal, the screen of the mobile terminal is a touch screen, and when the image shooting interface is started, a shooting button is displayed in the image shooting interface.
The shooting button detection area is an area opposite to the shooting button, and the area can be a cylindrical area opposite to the shooting button, and the cross section of the cylindrical area is the same as the cross section of the shooting button in shape and size. Of course, the area may also include the cylindrical area and have a larger volume than the cylindrical area; the region may also be contained within the cylindrical region.
The mobile terminal detects the shooting button area in real time, and the purpose is whether the finger contact appears in the detection area of the shooting button, and not only can the finger contact appear in the detection area of the shooting button, but also the distance between the finger contact and the shooting button can be detected. Wherein the finger contact is a part of a finger, usually a finger pad.
Step 102: and starting dynamic image shooting when the finger contact is detected to be positioned in the shooting button detection area and the distance between the finger contact and the shooting button is smaller than a first preset value.
When the distance between the finger contact and the shooting button is detected, the distance between the finger contact and the screen can be identified through ultrasonic waves integrated in the screen of the mobile terminal or a Home key in the mobile terminal, and the distance is the distance between the finger contact and the shooting button.
It should be noted that, in the specific implementation process, the first preset value may be set by a person skilled in the art according to actual requirements, and this is not specifically limited in the embodiment of the present invention. And the finger always carries out dynamic image shooting from the first preset value of the distance shooting button to the position of the distance shooting button from the first preset value of the distance shooting button after the finger clicks the shooting button and returns to the position of the distance shooting button again.
Step 103: and after detecting that the finger touch point touches the shooting button, stopping dynamic image shooting when detecting that the distance relation between the finger touch point and the shooting button meets the shooting stopping condition.
The operation of the finger contact touch shooting button can be detected through a pressure sensor arranged below the shooting button, specifically, the pressure sensor detects the pressure value applied to the shooting button, the central processing unit acquires the pressure value detected by the pressure sensor, and whether the shooting button receives the finger contact touch is judged according to the pressure value.
The shooting stop condition may be set by a person skilled in the art according to actual requirements, and may be, for example: stopping dynamic image shooting when the distance between the finger contact and the shooting button is larger than a certain value; the method can also comprise the following steps: and stopping shooting the dynamic image after the finger contact leaves the button detection area for preset time.
According to the dynamic image shooting method provided by the embodiment of the invention, the starting of dynamic image shooting and the stopping of dynamic image shooting are determined by detecting the distance between the finger contact and the shooting button. By the dynamic image shooting method provided by the embodiment of the invention, if a user wants to shoot a dynamic image for a long time, the moving speed of the finger contact to the shooting button and the moving speed of the finger contact far away from the shooting button are reduced, if the user wants to shoot the dynamic image for a short time, the moving speed of the finger contact to the shooting button and the moving speed of the finger contact far away from the shooting button are increased, and the user can control the start-stop range of the dynamic image according to personal requirements, so that the use experience of the user can be improved.
Example two
Referring to fig. 2, a flowchart illustrating steps of a moving image capturing method according to a second embodiment of the present invention is shown.
The dynamic image shooting method of the embodiment of the invention comprises the following steps:
step 201: a change in distance between the finger touch point and the photographing button is detected in the detection area.
The image shooting method in the embodiment of the invention is suitable for the mobile terminal. The screen of the mobile terminal is a touch screen, and when the image shooting interface is started, a shooting button is displayed in the image shooting interface.
The shooting button detection area is a cylindrical area opposite to the shooting button. As shown in fig. 3, the area E is a shooting button detection area, the area F is a screen of the mobile terminal, the area G is a shooting button on the screen, the area D is a finger contact, the area a is a first preset value, the area B is a second preset value, and the area C is a third preset value.
The mobile terminal detects the shooting button detection area in real time, and the purpose is to detect the distance between the finger contact and the shooting button after the finger contact appears in the shooting button detection area.
Step 202: and starting dynamic image shooting when the finger contact is detected to be positioned in the shooting button detection area and the distance between the finger contact and the shooting button is smaller than a first preset value.
And starting a dynamic image shooting function when the distance between the finger contact and the shooting button is equal to or less than a preset value, shooting the dynamic image, and continuously shooting the dynamic image in the process that the finger contact moves towards the shooting button.
The speed of the finger contact approaching the shooting button is in inverse proportion to the shooting time length, namely the shooting time length is shorter when the speed is higher, and the shooting time length is longer when the speed is lower. Specifically, the distance between the finger touch point and the photographing button may be detected by ultrasonic waves integrated within a screen of the mobile terminal or a Home key in the mobile terminal.
Preferably, after the start of the moving image photographing, the mobile terminal may also perform the moving image photographing while detecting the movement of the finger touch point to the photographing button, and select a preset number of frame images from the photographed image frames. The desktop image of the moving image may be selected from the selected preset number of frame images. The specific process of selecting the preset number of frame images is shown in step 203 and step 204.
Step 203: and shooting a dynamic image in the process of detecting that the finger contact moves towards the shooting button, and marking each shot frame image when the distance between the finger contact and the shooting button is within a preset range.
The upper limit value of the preset range is a second preset value B, and the lower limit value is a third preset value C. The second preset value is smaller than the first preset value, and the third preset value is smaller than the second preset value.
When the distance between the finger contact and the shooting button is within the preset range, the shot frame images are closest to the scene when the finger contact touches the shooting button, therefore, the shot images within the preset range are marked, and the preset number of frame images are selected from the marked frame images.
Preferably, during the movement of the finger contact point to approach the shooting button, a change that the finger gradually approaches the shooting button is presented on the shooting button, and the appearance of the shooting button is adjusted along with the change of the distance between the finger contact point and the shooting button. The optimal mode can provide visual perception for the user, and the user can visually perceive the distance relation between the finger contact and the shooting button and whether the shooting button is successfully touched.
Step 204: and selecting images with the definition higher than a preset value from the marked frame images.
The desktop image of the moving image is selected from the images selected in this step.
Preferably, when a preset number of frame images are selected, the image selection may be performed according to the definition of the image, and the image may be selected by determining whether a target object included in the image is prominent. For example: when the ratio of the pixels occupied by the target object in the preset image to the total pixels of the frame image is higher than a certain ratio, the frame image is determined to be selected as one frame image in the preset number of frame images.
Step 205: and after detecting that the finger contact touches the shooting button, stopping shooting the dynamic image when detecting that the distance between the finger contact and the shooting button is greater than a first preset value.
Namely, after the finger touches the shooting button, the shooting of the dynamic image is stopped after the finger returns to the point A again.
In addition to the condition for stopping the moving image photographing shown in step 205, the moving image photographing may be stopped after a preset time, counted from when the distance between the finger touch point and the photographing button is greater than the first preset value.
Namely, after the finger touch point touches the shooting button, the user returns to the point A again and then leaves the detection area of the shooting button for preset time, and then the dynamic image shooting is stopped. Wherein the preset time may be set to 5 s.
Preferably, in the moving process that the finger contact is close to the shooting button, the change that the finger contact is gradually close to the shooting button is presented on the shooting button, in the moving process that the finger contact is far from the shooting button, the change that the finger contact is gradually far from the shooting button is presented on the shooting button, and through the change of the display interface of the shooting button, the user can perceive the process of starting and ending shooting. I.e., the appearance of the photographing button, varies with the distance between the finger contact and the photographing button.
For example: the color of the shooting button gradually becomes darker when the finger contact moves from A to C, and gradually becomes lighter when the finger contact moves from C to A. For another example: the visual depth of the photographing button becomes gradually deeper when the finger contact moves from a to C, and becomes gradually shallower when the finger contact moves from C to a.
Step 206: and storing the shot dynamic images, and selecting one frame of image from a preset number of frames of images as a desktop image of the dynamic image.
In this step, the mobile terminal automatically selects one frame of image from the pre-selected frames of images as the desktop image of the captured dynamic image.
In the selection, a key frame image captured at a time point closest to a moment when the finger touches the capture button may be selected as the desktop image.
Step 207: and receiving a modification instruction of the desktop image of the dynamic image by the user.
A desktop image has been generated for the moving image photographed this time through step 206, and if the user wants to modify the desktop image, steps 207 to 210 are performed.
The modification instruction may be an instruction triggered by an operation of right-clicking the desktop image.
Step 208: and displaying the frame images with the preset number according to the modification instruction.
Each displayed frame image can be selected by a user.
Step 209: and detecting the selection operation of the user on the preset number of frame images.
The operation of selecting the key frame image may be a single-click operation, a double-click operation, a long-press operation, or the like on the image, which is not particularly limited in the embodiment of the present invention.
Step 210: and replacing the current desktop image of the dynamic image by the image corresponding to the selection operation.
For example: in step 206, the desktop image automatically generated by the mobile terminal for the dynamic image is image a, and in step 209, the image selected by the user is image B, and image B is used to replace image a.
The dynamic image shooting method provided by the embodiment of the invention has the beneficial effects that the dynamic image shooting method shown in the first embodiment has, and can also provide an interface for a user to modify the desktop image, and the user can select any frame image from the preset number of frame images as the desktop image according to personal requirements, so that the personalized requirements of the user can be met, and the use experience of the user is improved.
