The following examples are illustrative of the present application, but are not intended to limit the scope of the present application.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is to be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with one another without conflict.

In the following description, the terms "first", "second", "third" and the like are merely used to distinguish similar objects and do not represent a specific ordering of the objects, it being understood that the "first", "second", "third" may be interchanged with a specific order or sequence, as permitted, to enable embodiments of the application described herein to be practiced otherwise than as illustrated or described herein.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.

An embodiment of the present application provides an image processing method, as shown in fig. 1A, including:

step S110, a mode instruction is acquired, wherein the mode instruction comprises a target resolution and a shooting mode;

here, the target resolution is the display resolution of the image, the resolution determines the degree of fineness of the details of the image, and the higher the resolution of the image is, the more pixels are included, and the clearer the image is. In an implementation process, a target resolution required by a user can be acquired through an application program based on instructions of the user. For example, the user may input a request for resolution at the operation interface to determine the target resolution, and may also determine the target resolution by gesture operation of the screen.

The photographing modes include at least a large viewing angle mode and a small viewing angle mode. Wherein a large view mode may be used to obtain a panoramic image and a small view mode may be used to focus on a local image such as a task portrait or the like. In the implementation process, an independent application can be set to provide a user with a mode required by setting, and the function can be integrated into the application for acquiring the target image, so that the mode is automatically set or the mode is actively set by the user according to the requirement of the user.

In the implementation process, the acquired mode instruction comprises the target resolution and the shooting mode.

Step S120, if the shooting mode is a first mode, determining a target area for acquiring at least one frame of image in the image sensor, wherein the target area is smaller than the image size of the image acquired by the image sensor;

here, the first mode may be a small view angle mode, i.e., a portrait mode of a person.

An Image Sensor (Image Sensor) converts an optical Image on a photosensitive surface into an electrical signal in a proportional relationship with the optical Image by a photoelectric conversion function of a photoelectric device. For example, image sensors such as Charge-coupled Device (CCD) sensors, complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS) sensors, and the like are all important components that make up digital cameras. The pixel is the minimum unit of sensitization of the image sensor, namely the minimum unit of the image. The number of pixels is determined by the number of photosensors on the CCD/CMOS, one photosensor may correspond to each pixel. The larger the pixel, the more photosensitive elements. The pixels are represented by two numbers, e.g., 720×480, 720 representing the number of pixels contained in the image length direction, 480 representing the number of pixels contained in the image width direction, the product of the two being the number of pixels of the camera. The pixel units of the image sensor are Megapixels (MP), namely megapixels, commonly 2M, 5M, 13M and the like,

In an implementation process, a target area can be determined in a pixel area of the image sensor, where the target area is smaller than an image size of an image acquired by the image sensor and covers a target object to be acquired.

And step S130, processing pixel information of at least one frame of the target area based on the target resolution to obtain and display at least one frame of target image.

In the implementation process, the acquired pixel information of the target area can be processed based on the target resolution, and the obtained target image meets the requirement of the target resolution.

Fig. 1B is a schematic diagram for framing and restoring a target area according to an embodiment of the present application, and as shown in fig. 1B, the schematic diagram includes an original image sensor pixel 11, a framed target area 12 and a target image 13, where,

in some embodiments, in the case of determining that the target resolution is 5M, a region including the target is selected on the image sensor of the 5M pixel point, and the proportion of the selected region is also determined by the target resolution 5M. The frame-selected target area 12 selected based on the target resolution 5M restoration frame can obtain a target image 13 in which the target corresponds to the enlargement. Since the target resolution is consistent with the pixel index of the image sensor, the obtained target image 13 has partial image loss, but the target image is enlarged on the basis of satisfying the target resolution.

In some embodiments, in the case of determining that the target resolution is 2.1M, a region including the target is selected on the image sensor of the 5M pixel point, and the proportion of the selected region is determined by the target resolution of 2.1M. The frame-selected target region 12 selected based on the target resolution 2.1M restoration frame can obtain the target image 13 in which the target correspondence is enlarged and there is no image loss.

In some embodiments, in the case of determining that the target resolution is 0.92M, a region including the target may be framed on the image sensor of the 5M pixel point, and the framed region proportion is also determined by the target resolution of 0.92M. The frame-selected target area 12 selected based on the target resolution 0.92M restoration frame can obtain the target image 13 with the target corresponding to the enlarged and without image loss.

In the embodiment of the application, a mode instruction is firstly acquired, wherein the mode instruction comprises a target resolution and a shooting mode; then, if the shooting mode is a first mode, determining a target area for acquiring at least one frame of image in the image sensor, wherein the target area is smaller than the image size of the image acquired by the image sensor; and finally, processing pixel information of at least one frame of the target area based on the target resolution to obtain and display at least one frame of target image. In this way, the target area is selected by using the pixel information frame on the image sensor in the first mode based on the target resolution, and the target image meeting the target resolution is obtained based on the pixel information of the target area, so that the image loss can be effectively reduced on the basis of meeting the target resolution.

An embodiment of the present application provides an image processing method, as shown in fig. 2, including the following steps:

step S210, acquiring a mode instruction, wherein the mode instruction comprises a target resolution and a shooting mode;

step S220, determining the shooting mode as a second mode;

here, the second mode may be a large viewing angle mode, i.e., a panorama mode.

Step S230, determining at least one frame of the target area as an original area of an image acquired by the image sensor;

in the second mode, the target area may be the original area of the image acquired by the image sensor, i.e. all pixel information on the image sensor is acquired.

And step 240, processing pixel information of at least one frame of the target area based on the target resolution to obtain and display at least one frame of target image.

In the implementation process, a sampling process or a pixel point merging mode can be adopted to obtain a target image meeting the requirement of the target resolution based on the target resolution.

In the embodiment of the application, the shooting mode is first determined to be a second mode; and then determining at least one frame of the target area as an original area of an image acquired by the image sensor. In this way, it is possible to achieve a target image that meets the target resolution requirement in the second mode.

In some embodiments, the step S120 of determining the target area for acquiring the at least one frame of image in the image sensor if the shooting mode is the first mode may be implemented by the following steps:

step 121, determining the shooting mode as a first mode;

step 122, determining at least one frame of the target area based on the target resolution.

In practice, as shown in FIG. 1B, different target areas may be determined in the image sensor based on different target resolutions.

For example, for the case where the target resolution requirement is 1080P (2.1M), the image sensor resolution is greater than this. In this way, an optimized view angle frame can be preset at each target resolution, so that a target area with the target resolution of 2.1M can be obtained by direct 'crop' (frame selection) at the bottom layer of an image sensor (such as 5M), and the core requirement of corresponding amplification of a target in the target area is considered.

In the embodiment of the application, the shooting mode is first determined to be a first mode; at least one frame of the target region is then determined based on the target resolution. In this way, the pixels within the resulting target area can be used to process the resulting target image that meets the target resolution requirements.

In some embodiments, the above step 122 "determining the target region for at least one frame based on the target resolution" may be achieved by:

step 1221, determining size information corresponding to a target object in the target image, where the target object is an object determined based on the first mode;

here, the target object may be determined first in the first mode, and size information of pixel information corresponding to the target object in the image sensor may be determined.

Step 1222, determining at least one frame of the target area based on the size information and the target resolution.

In the implementation process, the target area can be determined based on the size information corresponding to the target object and the target resolution, so that the determined target area can not only meet the target resolution, but also completely restore the target object under the condition of generating the target image.

In the embodiment of the application, firstly, size information corresponding to a target object in the target image is determined, wherein the target object is determined based on the first mode; at least one frame of the target region is then determined based on the size information and the target resolution. In this way, the target region obtained can completely restore the target object while satisfying the target resolution when generating the target image.

In some embodiments, as shown in fig. 3, the above step 1222 "determining the target area of at least one frame based on the size information and the target resolution" may be implemented by:

step S310, determining at least one frame first area based on the target resolution;

step S320, determining that all information of the target object can be acquired in at least one frame of the first area based on the size information;

step S330, determining the first region as the target region;

for example, in the case of a target resolution of 1080P, the determined first region is able to acquire all information of the target object.

Step S340, determining that all information of the target object cannot be acquired in the first area based on the size information;

for example, in the case where the target resolution is 720P, the determined first area cannot collect all information corresponding to the target.

Step S350, determining at least one frame of second area based on the size information, wherein the second area is larger than the first area, and the second area can collect all information of the target object;

in some embodiments, the first region may be enlarged to enable the determination that the second region is capable of collecting all information of the target object based on the size information of the target object.

For example, if the resolution is 720P, the frame may be small, the portrait may not be fully overlaid, and a larger frame is required to overlay the target object. The frame can be determined according to the boundary of the target object, and can be directly enlarged to 1080P, namely, the frame selection can be performed again by using 1080P of target resolution, so that a second area capable of collecting all information of the target object is obtained. If there is still a 1080P box that cannot cover all of the target objects, the box may be enlarged again. Thus, the obtained frame is large, i.e. the obtained original pixel points are more, and the whole portrait can be covered.

In the implementation process, the 720P target image can be obtained by sampling due to the fact that the number of the acquired native pixels is large.

Step S360, determining the second area as the target area.

In the embodiment of the application, all information which can collect the target object in at least one frame of the first area is determined based on the size information; the first region is determined as the target region. Determining that all information of the target object cannot be acquired in the first area based on the size information; determining at least one frame of second area based on the size information, wherein the second area is larger than the first area, and the second area can acquire all information of the target object; and determining the second area as the target area. Thus, pixel information in the determined target area can be realized, and restoration of all information of the target object can be realized.

In some embodiments, the step S130 "process the pixel information of the target area of at least one frame based on the target resolution, and obtain and display at least one frame of the target image" may be implemented by:

step 131, determining that the resolution corresponding to the image generated based on the pixels of the target area is greater than the target resolution;

in practice, it may be predetermined that the resolution of the image generated based on the pixels of the target region is greater than the target resolution. In this case, the acquired pixel information is large.

And 132, processing pixels of at least one frame of the target area by utilizing pixel merging, wherein the obtained at least one frame of the target image meets the target resolution.

Since there may be more pixels in the acquired target area than are needed to generate the target image. Pixels of at least one frame of target area may be processed using pixel binning to obtain a target image satisfying the target resolution.

In the embodiment of the application, first, determining that a resolution corresponding to an image generated based on pixels of the target area is greater than the target resolution; and then, processing pixels of at least one frame of the target area by utilizing pixel merging, wherein the obtained at least one frame of the target image meets the target resolution. In this way, when the number of pixels in the acquired target region is large, a target image satisfying the target resolution can be obtained by the pixel merging method.

In some embodiments, the above image processing method further comprises the steps of:

step S140, acquiring an image magnification instruction, acquiring an updated target resolution based on the image magnification instruction, and redefining the target area based on the updated target resolution.

In the implementation process, after the user acquires the target image, there is also a need to zoom in the target object in the target image again. In this case, the updated target resolution may be acquired in response to an image magnification instruction triggered by the user, and the target region corresponding to the updated target resolution may be determined again among the target regions newly determined therebetween based on the target resolution.

In the embodiment of the application, an image amplifying instruction is acquired, an updated target resolution is acquired based on the image amplifying instruction, and the target area is redetermined based on the updated target resolution. In this way, a re-magnification of the target object in the target image can be achieved.

An embodiment of the present application provides an image processing apparatus as shown in fig. 4A, including:

an image sensor 41 for acquiring at least one frame of image;

a driving component 42 connected with the digital signal processing component and used for acquiring a mode instruction, wherein the mode instruction comprises a target resolution and a shooting mode; transmitting the mode instruction to the digital signal processing component;

a digital signal processing component 43, connected to the driving component and the image sensor, for determining a target area for acquiring at least one frame of image in the image sensor, where the target area is smaller than or equal to the image size of the image acquired by the image sensor; processing pixel information of at least one frame of the target area based on the target resolution to obtain at least one frame of target image;

a display component 44 for displaying at least one frame of the target image.

In an embodiment of the present application, an image processing apparatus includes: an image sensor for acquiring at least one frame of image; the driving assembly is connected with the digital signal processing assembly and used for acquiring a mode instruction, wherein the mode instruction comprises a target resolution and a shooting mode; transmitting the mode instruction to the digital signal processing component; the digital signal processing component is connected with the driving component and the image sensor and is used for determining a target area for acquiring at least one frame of image in the image sensor, wherein the target area is smaller than or equal to the image size of the image acquired by the image sensor; processing pixel information of at least one frame of the target area based on the target resolution to obtain at least one frame of target image; and the display component is used for displaying at least one frame of the target image. In this way, the image processing apparatus can select the target area by using the pixel information frame on the image sensor in the first mode based on the target resolution, and obtain the target image satisfying the target resolution based on the pixel information of the target area, and can effectively reduce the image loss based on satisfying the target resolution.

Fig. 4B is a schematic flow chart of image processing instruction transmission according to an embodiment of the present application, as shown in fig. 4B, the instruction transmission includes the following steps:

step S410, acquiring target resolution by using a camera application;

here, the camera application may be an application for acquiring an original image and presenting a target image.

Step S420, acquiring a shooting mode by using a camera setting application;

here, the camera setting application may be an application for setting a photographing mode. The photographing mode may include an original mode, i.e., a large viewing angle mode, and a portrait mode, i.e., a small viewing angle mode.

In the implementation process, the camera setting application may be integrated into the camera application described in step S410, or may be a stand-alone application independent of the camera application described in step S410. The camera setting application can provide the user with the active setting of the shooting mode, and can also automatically set the shooting mode according to the shooting requirement of the user.

Step S430, the driving component sends a target resolution acquired by the camera application and a shooting mode composition mode instruction acquired by the camera setting application to the digital signal processing component; the digital signal processing component processes the original video stream based on the mode instruction, obtains a target video stream and sends the target video stream to the camera application through the driving component.

Here, the photographing mode in the mode instruction includes an original mode and a portrait mode.

If the mode command is the original mode, the digital signal processing component adopts a large visual angle to collect images, and a target video stream obtained by processing the collected video stream is transmitted to the driving component.

If the mode command is a portrait mode, the digital signal processing component adopts a small visual angle to collect images, and a target video stream obtained by processing the collected video stream is transmitted to the driving component.

For example, for a main stream video resolution of 1080P (2.1M) type, the sensor resolution is now greater than this. In the implementation process, an optimized view angle frame can be preset based on each target resolution, so that the target resolution such as 2.1M can be read out from the bottom layer of the image sensor (such as 5M) directly through "crop" (frame selection), and the core requirement of face amplification is simultaneously considered.

The drive component passes the target video stream to the camera application for presentation.

In the implementation process, the image processing instruction is executed on the basis of the function support of a digital signal processing component (DSP chip), and the DSP chip can realize an optimal strategy based on a superior instruction (application program and a driving component) so as to output a target image meeting the target resolution corresponding to the physical condition as originally as possible.

For example, the target resolution 1080P Full HD (FHD) is a core, most widely used. Taking 1080P as a core, the Crop strategy can be determined by considering the maximum resolution or the small view angle. The HD 720P of such smaller resolution may be processed from the 1080P frame selected pixel information, i.e., scaled down, to obtain a target image that meets the 720P requirements.

Here, different systems may individually formulate different policies, and policies of respective resolutions may be individually assigned, and the policy logic may be provided in a driving component of the camera.

In the embodiment of the application, the native pixels "crop" are utilized for the small view mode or the large view mode of the actual physical situation with different resolutions. Therefore, under different shooting requirements of users, the image loss can be effectively reduced, and the resolution requirements of the users are met.
