Description

Method, electronic device, apparatus, and computer-readable storage medium for generating image

Technical Field

The present disclosure relates to a method of generating image data, an electronic device implementing the method, a computer readable medium and apparatus comprising program instructions stored thereon for performing the method.

Background

Traditionally, electronic devices such as smartphones are equipped with digital cameras that can capture objects, such as people.

Here, there are two ways of photographing, one focusing on the main object and the other balancing the main object and the background.

For example, a portrait photo needs to draw attention to a person. In this case, the background is not important. In some cases, the background may interfere with the primary object.

In taking photographs such as travel photographs, a user wishes to take a person and a background at the same time. In this case too, the background should be well captured (with respect to focus, brightness and color).

They are then selected according to the user's intention. Furthermore, each mode requires control of multiple settings. There are the following problems.

For example, the user needs to control various parameter settings, which requires experience and knowledge. Only the user knows their intent. However, the camera assembly of the electronic device cannot take into account the user's intent.

In particular, for example, when a user shoots flowers using a camera assembly, there is a case where the user shoots main subject flowers to emphasize them, and there is a case where the user shoots the main subject flowers together with a background.

In the case where the user emphasizes the main object flower using the camera assembly, the main object flower is photographed so as to stand out in the background by making the flower appear most beautiful by adjusting exposure and white balance, blurring the background.

On the other hand, in the case where the user photographs the main subject flower together with the background using the camera module, the camera module photographs so that the whole is in focus by adjusting the exposure and white balance in the camera module so that the whole image is right.

However, shooting "only the flower is the main object" or "the main object flower together with the background" is the user's intention. The camera component cannot recognize the user's intent.

Throughout the description, identical or similar elements and elements having identical or similar functions are denoted by identical reference numerals. The embodiments described herein with reference to the drawings are illustrative and are intended to be illustrative of the present disclosure, but should not be construed as limiting the present disclosure.

Here, fig. 1 illustrates a plan view of a first side of an electronic device 10 according to an embodiment of the present disclosure, and fig. 2 illustrates a plan view of a second side of the electronic device 10 according to an embodiment of the present disclosure. The first side may be referred to as the back side of the electronic device 10 and the second side may be referred to as the front side of the electronic device 10.

As shown in fig. 1 and 2, the electronic device 10 may include a display 20 and a camera assembly 30. In the present embodiment, the camera assembly 30 includes a first primary camera 32, a second primary camera 34, and a secondary camera 36. The first and second primary cameras 32, 34 may capture images on a first side of the electronic device 10 and the secondary camera 36 may capture images on a second side of the electronic device 10. Thus, the first main camera 32 and the second main camera 34 are so-called external cameras (out-cameras), and the sub-camera 36 is a so-called internal camera (in-camera). For example, the electronic device 10 may be a mobile phone, tablet, personal digital assistant, or the like.

Note that the display 20 is, for example, a touch screen that accepts an operation input of the user U.

Fig. 3 shows a block diagram of the electronic device 10 according to the present embodiment. As shown in fig. 3, in addition to the display 20 and the camera assembly 30, the electronic device 10 may include a main processor 40, an image signal processor 42, a memory 44, a power circuit 46, and a communication circuit 48. The display 20, camera assembly 30, main processor 40, image signal processor 42, memory 44, power circuit 46, and communication circuit 48 are interconnected by bus 50.

The processor 100 includes a main processor 40 and an image signal processor 42.

As will be described later, the processor 100 acquires a reference camera image by controlling the camera assembly 30. Further, the processor 100 acquires a processed camera image by performing image processing on the reference camera image.

The main processor 40 executes one or more programs stored in the memory 44. The main processor 40 implements various applications and data processing (including image data processing) of the electronic device 10 by executing programs. The main processor 40 may be one or more computer processors. The main processor 40 is not limited to one central processing unit (Central Processing Unit, CPU) core, i.e., it may have a plurality of CPU cores. The main processor 40 may be a main CPU of the electronic device 10, an image processing unit (Image Process Unit, IPU) or a digital signal processor (Digital Signal Processing, DSP) provided together with the camera assembly 30.

The image signal processor 42 controls the camera assembly 30 and processes various image data captured by the camera assembly 30 to generate target image data. For example, the image signal processor 42 may perform a demosaicing process, a noise reduction process, an auto exposure process, an auto focus process, an auto white balance process, a high dynamic range process, and the like on image data captured by the camera assembly 30.

In this embodiment, the main processor 40 and the image signal processor 42 cooperate with each other to generate target image data of an object captured by the camera assembly 30. That is, the main processor 40 and the image signal processor 42 are configured to capture an image of an object through the camera assembly 30 and perform various image processes on the captured image data.

The memory 44 stores programs to be executed by the main processor 40 and the image signal processor 42, as well as various data. For example, data of the captured image is stored in the memory 44.

It is noted that images, including images such as captured images and generated images, are present in the electronic device 10 in the form of image data (e.g., data of the images are stored in the memory 44). Further, the processor 100 processes the image into image data.

In particular, for example, memory 44 includes program code. The memory 44 and program code are configured to, with the processor 100, cause the electronic device 10 to perform: acquiring a reference camera image by controlling the camera assembly 30 to capture at least one main object specified by a first operation input of a user; displaying an initial camera image obtained by performing initial image processing on the reference camera image on the display 20; selecting a processing parameter set from a plurality of processing parameter sets specifying a plurality of image processes having different processing contents according to a second operation input by a user; and generating a processed camera image by performing image processing specified in the selected processing parameter set on the reference camera image.

The memory 44 may include high-speed random access memory (Random Access Memory, RAM) and/or non-volatile memory such as flash memory and disk memory. That is, the memory 44 may include a non-transitory computer readable medium storing a program.

Further, in the present embodiment, the program instructions of the image generation process are stored in a non-transitory computer-readable medium of the memory 44. When the program instructions are read from the memory 44 and executed in the main processor 40, the main processor 40 implements an image generation process.

Here, fig. 4 shows a block diagram of a processor 100 according to an embodiment of the present disclosure.

As shown in fig. 4, the processor 100 shown in fig. 4 may be replaced with a device. The device comprises: a camera image acquisition unit 100a configured to acquire a reference camera image by controlling the camera assembly to capture at least one main object specified by a first operation input of a user; a display unit 100b configured to display, on a display, an initial camera image obtained by performing initial image processing on the reference camera image; a parameter selection unit 100c configured to select one processing parameter set from a plurality of image processing parameter sets that specify a plurality of image processes having different processing contents, according to a second operation input by a user; and a camera image generation unit 100d configured to generate a processed camera image by performing image processing specified in the selected processing parameter set on the reference camera image.

In this case, the electronic device 10 may be represented as an apparatus including the processor 100.

[ image data generation method ]

Next, an example of a method of generating image data by the electronic apparatus 100 having the above-described configuration and function according to the present embodiment will be described.

Here, fig. 5A is a diagram showing a display example of an electronic device that displays a camera image weighted on a main object. Further, fig. 5B is a diagram showing a display example of an electronic device that displays camera images weighted on a main object and a background.

The processing of the processor 100 of the electronic device 10 shown in fig. 3 will be mainly described below.

First, the processor 100 captures at least one main object Z designated by a first operation input of a user by controlling the camera assembly 30, thereby obtaining a reference camera image.

The processor 100 sets the object of the camera assembly 30 that has been focused on in the reference camera image as the main object Z.

In the examples shown in fig. 5A, 5B, 6 and 7, the main object Z is a flower, but may be an object other than a flower.

The processor 100 then displays an initial camera image on the display 20, the initial camera image being obtained by performing an initial image process on the reference camera image.

Then, the processor 100 selects one processing parameter set from among a plurality of processing parameter sets that specify a plurality of image processes having different processing contents, according to a second operation input by the user.

For example, camera assembly 30 has many features to achieve "focus on target" or "balanced focus on target and background".

For example, the image processing performed by the processor 100 on the reference camera image includes: the foreground on the background image is adjusted based on the image of the main object Z in the reference camera image or the entire image of the reference camera image (the foreground is turned on or off).

Here, the "foreground" controls the focus blur on the background so that the main object will stand out in the background.

Further, the image processing performed by the processor 100 for the reference camera image includes: the white balance of the reference camera image is adjusted based on the image of the main object Z in the reference camera image or the entire image of the reference camera image.

Further, the image processing performed by the processor 100 for the reference camera image includes: the brightness is adjusted based on the image of the main object Z in the reference camera image or the entire image of the reference camera image.

Here, an "extended depth of focus (Extended Depth Of Focus, EXOF)" captures multiple frames to allow good focus on both the target and the background.

Further, the image processing performed by the processor 100 for the reference camera image includes: the high dynamic range (High Dynamic Range, HDR) process is turned on or off.

"HDR" captures multiple frames so that both the object and the background have good brightness.

Here, for example, as shown in fig. 6 and 7, the second operation input from the outside is the second operation input after the user U displays the initial camera image on the display 20. In this case, as described above, the display 20 is, for example, a touch screen that receives an operation input of the user U.

In this case, for example, according to an operation input by the user U, the processor 100 selects a first processing parameter set defining a first image processing (fig. 5A, 6) or a second processing parameter set defining a second image processing (fig. 5B, 7) whose processing content is different from that of the first image processing from among the plurality of processing parameter sets.

For example, the user U can switch between the first processing parameter set and the second processing parameter set by operating (touching) the button 20a (fig. 6) or the button 20b (fig. 7) displayed on the display screen 20.

Here, fig. 6 is a diagram for explaining an example of image processing on a camera image weighted on a main object.

In the case of "focusing on a main object", brightness is considered based on the main object. Furthermore, HDR is off (background is not important). In addition, the aperture is opened to narrow the depth of field or to turn on the foreground function. Further, the white balance gain is considered based on the main target.

On the other hand, fig. 7 is a diagram for explaining an example of image processing on camera images weighted on a main object and a background.

In the case of "focus both", brightness is considered based on the entire image. Furthermore, HDR is turned on in the case of a wide dynamic range scene to fade over bright/dark areas. In addition, the aperture is narrowed to obtain a wide depth of focus and to close the foreground function to capture the background as well. Furthermore, white balance gain is considered based on the entire image.

In this way, the processor 100 acquires a processed camera image by performing image processing specified in the selected processing parameter set on the reference camera image.

Finally, the processor 100 displays a processed camera image on the display 20, the processed camera image being obtained by performing an image processing defined in the selected set of processing parameters on the reference camera image.

Thus, with this scheme, the user can set various settings based on the balance between the target object and the background.

Here, fig. 8A is a diagram showing an example of a display of an electronic device that displays a camera image weighted on a main object and a slider bar for input operation by a user. Further, fig. 8B is a diagram showing an example of a display of an electronic device that displays a camera image weighted on a main object and a background and a slide bar for an input operation by a user.

For example, as shown in fig. 8A and 8B, the processor 100 may display a slider 20c on the display 20 for inputting an operation of the user U regarding continuous or stepwise adjustment of the content of the image processing for the reference camera image.

It is noted that the processor 100 may display a dial on the display 20 instead of the slider bar 20c for inputting an operation of the user U related to continuously or stepwise adjusting the content of the image processing with respect to the reference camera image.

In this way, a dial or sliding bar may be applied instead of buttons. The dial or slider bar may control the balance between the main object and the background.

As described above, in response to the operation input of the user U, the processor 100 can adjust the image weight of the main object Z in the image processing.

Here, fig. 9A is a diagram showing an example of a display of an electronic device that displays a camera image weighted on a main object as an initial camera image. Further, fig. 9B shows a diagram of an example of a display of an electronic device that displays a camera image weighted on a main object and a background as an initial camera image.

For example, as shown in fig. 9A and 9B, the processor 100 may select a set of processing parameters to be performed for obtaining an initial camera image based on the proportion of the image region of the main object Z in the reference camera image.

More specifically, as shown in fig. 9A, when the proportion of the image area of the main subject Z in the reference camera image is equal to or greater than a preset selection threshold, the processor 100 displays an initial camera image on which a first image process, which is defined as an initial image process (initial state is a large main subject) in a first process parameter set, on the display 20.

In this case, the operation buttons 20a are displayed on the display 20.

On the other hand, as shown in fig. 9B, when the proportion of the image area of the main subject Z in the reference camera image is smaller than the selection threshold, the processor 100 displays the initial camera image on which the second image processing, which is defined as the initial image processing (initial state is a small main subject) in the second processing parameter set, on the display 20.

In this case, the operation buttons 20b are displayed on the display 20.

In this way, the electronic device 10 may take into account the initial state of "focus master object" or "balance master object with background" using the master object scale on the image.

As described above, an electronic device according to the present invention includes: a camera assembly configured to acquire a camera image by capturing an object; a display; at least one processor; and at least one memory including program code. Further, the at least one memory and the program code are configured to, with the at least one processor, cause the electronic device to perform: acquiring a reference camera image by controlling the camera assembly to capture at least one primary object specified by the first operational input; displaying an initial camera image obtained by performing initial image processing on the reference camera image on a display; selecting a processing parameter set from a plurality of processing parameter sets specifying a plurality of image processes having different processing contents according to a second operation input; and generating a processed camera image by performing image processing specified in the selected processing parameter set on the reference camera image.

Accordingly, the electronic device according to the present invention solves the above-mentioned problems through a user interface so that the camera module controls various parameters based on user commands. Thus, the user can control various settings by one action. Thus, the user can obtain a desired image without difficulty.
