Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to improve the efficiency of acquiring a target image, embodiments of the present invention provide an image acquisition method, an image acquisition apparatus, a device, and a medium.
Example 1:
fig. 1 is a schematic diagram of an image acquisition process provided in an embodiment of the present invention, where the process includes the following steps:
s101: and receiving an adjustment instruction of the size of the preview window of the image, and determining an adjusted target preview area.
The image acquisition provided by the embodiment of the invention is applied to the electronic equipment, and the electronic equipment can be intelligent equipment such as image acquisition equipment, terminals and the like.
Because the image needs to be previewed when the image is acquired, the content included in the image to be acquired can be previewed in the preview window in advance, the electronic device in the embodiment of the invention includes the preview window, and the preview window can be included in a photographing application when a user in the electronic device photographs, or can be directly included in the electronic device, and after entering the preview window, the user can preview the image for the preview window. In order to improve user experience, in the embodiment of the present invention, the size of the preview window may be adjusted, and in order to achieve adjustment of the size of the preview window, in the embodiment of the present invention, an instruction for adjusting the size of the preview window may be input, and when the electronic device receives the instruction for adjusting the size of the preview window, it indicates that the size of the current preview window cannot meet the requirement of the user, and in general, the current preview window is a normal preview window after the electronic device is opened, for example, when the electronic device is a terminal, the current preview window is a size of a window for normally taking an image after a photographing application of the terminal is opened. When the terminal is opened and a photographing application is opened to photograph, the preview window is the largest when photographing is performed first, and therefore the adjustment command is generally a command for reducing the size of the preview window.
And after receiving the adjusting instruction, the electronic equipment adjusts the size of the preview window according to the adjusting instruction, and determines the area corresponding to the preview window obtained after adjustment as a target preview area.
S102: and if a photographing instruction is received, intercepting the acquired image according to the target preview area to acquire a target image.
In order to quickly and accurately acquire an image meeting the size requirement of a user, in the embodiment of the invention, when a photographing instruction is received, image acquisition is performed, wherein the photographing instruction can be a common photographing instruction and the like.
In the embodiment of the invention, after receiving the photographing instruction, the electronic device acquires the image, wherein the acquired image is the image corresponding to the size of the preview window before adjustment, and after acquiring the image, the electronic device intercepts the acquired image according to the size of the target preview area so as to acquire the target image matched with the size of the target preview area, so that the operation of a user is facilitated.
In addition, when the image is acquired, the target preview area may display the content to be acquired for previewing, and the non-target preview area may not display the content, which is equivalent to shielding the preview window, so that the user previews the content desired by the user.
When a photographing instruction is received and an image is acquired, intercepting the image, intercepting the acquired image according to the position of a target preview area in a preview window, wherein the target preview area is located at half of the size of an original preview window and at the lower half of the original preview window, when the image is intercepted, intercepting the image, taking the lower half of the intercepted image as a target image, and when the preview window is shielded, a picture when the target preview area is previewed is consistent with the angle of view of the acquired target image.
According to the embodiment of the invention, the target preview area is obtained by adjusting the size of the preview window before image acquisition, and the acquired image is intercepted according to the target preview area when the target image is obtained, so that the target image with the size consistent with that of the target preview area is obtained.
Example 2:
in order to improve the user experience, on the basis of the above embodiment, in the embodiment of the present invention, the instruction for adjusting the size of the preview window of the image includes:
and sliding any boundary in the boundary boxes forming the preview window.
In the embodiment of the present invention, in order to accurately acquire the target preview area, the adjustment instruction may be a sliding operation on any boundary of the bounding boxes forming the preview window, and the area outside the bounding box is a non-target preview area, and the size of the target preview area is determined according to the position when the sliding operation is stopped.
The preview window can be reduced by sliding operation from the boundary of the original preview window to the inside of the original preview window, so that the corresponding acquisition requirements are met. After the preview window is reduced, if the preview window needs to be enlarged, an adjustment instruction can be input into the electronic device, wherein the adjustment instruction can be a sliding operation performed on any boundary of the bounding boxes forming the preview window to the outside of the preview window.
The target preview area is the original preview window at the beginning, namely the length and the width of the non-target preview area are both 0 at the beginning, and the length or the width of the non-target preview area gradually increases along with the sliding operation from the boundary of the original preview window to the inside of the preview window. For example, when the upper boundary of the original preview window slides towards the inside of the preview window, the initial length h of the non-target preview area is 0, the length h of the non-target preview area gradually increases along with the sliding operation towards the inside of the preview window, when the sliding operation slides from the upper boundary of the original preview window to the lower boundary of the original preview window, the length of the non-target preview area is the length of the original preview window, reaches the maximum value, and is equivalent to that the preview area is completely shielded, wherein if the original length of the preview window is pos, h is more than or equal to 0 and less than or equal to pos. When sliding is performed on the left boundary or the right boundary, the same principle as the above description is not repeated herein.
When the preview area is reduced to the minimum, the length or width of the non-target preview area is gradually reduced along with the sliding operation of the border of the preview window to the outside of the preview window. For example, the upper boundary and the lower boundary of the preview area are overlapped with each other and are overlapped with the lower boundary of the original preview window, the initial length h of the non-target preview area is approximately equal to pos, theoretically, the length h of the non-target preview area is infinitely close to pos, but h is less than pos, when the upper boundary of the original preview window is subjected to sliding operation towards the outside of the preview window, the length h of the non-target preview area is gradually reduced along with the sliding operation towards the outside of the preview window, when the sliding operation slides to the upper boundary of the original preview window from the inside of the original preview window close to the lower boundary, the length of the non-target preview area is 0, the minimum value is reached, and the value is equivalent to that the preview area is not completely shielded, and h is more than or equal to. When sliding is performed on the left boundary or the boundary, the same principle as the above description is not repeated herein.
When the adjustment instruction is executed, the adjustment instruction may be slid into the preview window for different boundaries of the original preview window, for example, the adjustment instruction may be slid into the preview window for an upper boundary of the preview window, and after the adjustment instruction is not slid, the adjustment instruction may be slid into the preview window for a left boundary of the preview window. After the camera application is opened, the default aspect ratio of the preview window is started, the picture proportion is not different from that of the common image acquisition equipment, the diversity of the size of the finally acquired target image is increased by adjusting the preview window, and the default aspect ratio can be 4:3 or other aspect ratios, which is not limited herein.
The adjustment instruction may also be to input a specific gesture on the display interface of the electronic device, where different gestures correspond to different sizes of the adjusted target preview area, where the gesture may be a letter or may also be a specific symbol, for example, if the received adjustment instruction is that the letter is "s", the size of the target preview area is adjusted to 1/2 of the original preview window; if the letter of the received challenge operation is "m", the size of the target preview area is adjusted to 1/3 of the original preview window. The specific position of the target preview area on the terminal display interface may also be preset, for example, a letter may be drawn above the display interface to obtain the target preview area, and the target display area may be determined to be located above or below the original preview window. Specifically, how to determine the target preview area by means of a gesture, and how to determine the target preview area by means of what gesture are not limited herein.
Taking an adjustment instruction as an example to explain a sliding operation of a preview window from a boundary of an original preview window to an inside of the original preview window, fig. 2 is a schematic diagram of a terminal display interface provided in an embodiment of the present invention, where a white rectangular area 21 in fig. 2 is a preview window, is used for previewing content of an acquired image, and can be adjusted according to a size of the preview window, and a white circular area 22 in fig. 2 is a photographing key in an embodiment of the present invention, and when the terminal receives a trigger operation of the photographing key, the terminal will take a photograph, and the terminal display interface thereof may be a display interface of a camera application when the terminal performs image acquisition.
Fig. 3 is a schematic view of a display interface of a terminal after an instruction is adjusted for a size of a preview window according to an embodiment of the present invention, where a black rectangular region 31 in fig. 3 is a non-target preview region, and is used to shield an original preview window and enable an operation of taking a picture to be input in the black region, a white rectangular region 32 in fig. 3 is obtained as a target preview region after a sliding operation is performed on the display interface, a boundary of the target preview region is a boundary of a border frame that can perform the sliding operation, h is a length of the non-target preview region in the embodiment of the present invention, a width of the non-target preview region is a width of the original preview window, and a white circular region 33 in fig. 3 is a shooting key in the embodiment of the present invention, and when the terminal receives a trigger operation on the shooting key, the. And determining the intercepted area according to the size of the h value of the non-target preview area and the width of the original preview window. And because the length value pre-saved in the original preview window is pos and the length of the collected non-target preview area, the length of the target preview area can be determined to be pos-h, and the target image can be accurately acquired after the image is determined according to the width of the pre-saved original preview window.

In order to improve user experience and quickly acquire an image, in the embodiment of the present invention, after a frame proportion of a view is determined, that is, an adjusted target preview area is determined, an image is acquired, and a photographing instruction may be a common photographing instruction, for example, a photographing key is displayed on a display interface of an electronic device, or a photographing key is arranged at an edge of a housing of the electronic device, and the photographing instruction may be a trigger operation on the photographing key.
In order to further improve the efficiency of acquiring an image, in the embodiment of the present invention, receiving the photographing instruction may also be receiving a preset operation in a non-acquisition region, and in order to distinguish an original preview window, that is, a preview window in the prior art, a region capable of generating a target image is referred to as a target preview region, and the remaining regions in the original preview window are referred to as non-target preview regions. For the purpose of distinguishing, the target preview area and the non-target preview area may be distinguished by different colors, for example, the non-target preview area may be represented by black for distinguishing the non-target preview area from the target preview area. The preset operation may be any one of a click operation, a double click operation, a press operation, and the like on the non-target preview area.
In order to further improve the efficiency of acquiring the image, in the embodiment of the present invention, the receiving of the photographing instruction may also be receiving a voice instruction for image acquisition, for example, a "photographing" voice instruction.
In order to further improve the efficiency of acquiring the image, in the embodiment of the present invention, the receiving of the photographing instruction may also be receiving a preset operation of the target preview area, where the preset operation may be any one of a click operation, a double click operation, a press operation, and the like of the target preview area, and specifically, why the preset operation is performed is not limited herein.

and adjusting the size of the preview window according to the adjusting instruction, and if the size of the preview window simultaneously comprises a target preview area and a non-target preview area during adjustment, displaying the target preview area and the non-target preview area in a distinguishing manner.
In the embodiment of the present invention, in order to ensure that the content and the size of the target preview area viewed by the user are the content and the size of the target image that the user wants to obtain when previewing, in the embodiment of the present invention, if the target preview area and the non-target preview area are included at the same time, the target preview area and the non-target preview area are displayed in a differentiated manner in order to improve the user experience, wherein a pixel value of the non-target preview area may be set as a preset value for blocking the non-target preview area. And the preset value can be set to 0 or 255, that is, the non-target preview area is usually a full black or full white pixel point. Equivalently, the non-target preview area is shielded, so that the user can not see the picture in the non-target preview area, the picture in the determined target preview area meets the user requirement, and the user experience is improved. Specifically, how to distinguish the target preview area from the non-target preview area is not limited herein.

and saving the image and/or the target image to a preset storage position.
Because the user may no longer be satisfied with the content or size of the acquired target image after the target image is acquired subsequently, and because the original preview window is the size of the view-finding picture acquired through many experiments, the user usually holds the device in the hand when acquiring the image, so that the device keeps the image acquired after the device is stable, and the image acquired according to the size of the preview window usually still meets the public requirements, the acquired image can be stored in a preset storage position. Since the content in the target preview area sometimes meets the user's requirement during the framing, since the image displayed in the target preview area during the image preview is consistent with the view angle of the finally acquired target image and the content in the image is also consistent after the camera application software is entered, the acquired target image can be saved to a preset position, and the target image is obtained by capturing the image data of the image.
In the embodiment of the invention, after receiving a photographing instruction, the electronic device acquires image data, and the image sensor chip in the camera module outputs the image data, wherein the output image data is not different from the image data output by the common image acquisition device, and the CPU or other devices receive the image data, so that the subsequent operations are more complicated and a good effect cannot be achieved in order to avoid modification of underlying driver software, and therefore, the image data does not change in the process, and after receiving the image data, the image data is subjected to image signal processing, image coding and image compression to obtain an image, and the image is intercepted according to the information of the stored target preview area to obtain a target image, and the obtained image and/or the target image are stored. And when saving, the storage is generally in a jpeg format or a PNG format, wherein the specific storage is in what format, and the storage is not limited herein. And when the user views the target image at the preset storage position, the target image is consistent with the field angle of the user during image acquisition, so that adjustment or interception is not needed generally. When the image and/or the target image are saved, whether the specific saved image or the target image or the image and the target image are set by a user, and the acquired image and/or the target image are saved to a preset storage position according to the setting of the user.
