Description

METHOD OF GENERATING AN IMAGE, ELECTRONIC DEVICE, APPARATUS, AND COMPUTER READABLE STORAGE MEDIUM

TECHNICAL FIELD

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

BACKGROUND

Conventionally, there are electronic devices such as smartphones equipped with a digital camera that captures a subject such as a person.

With such conventional electronic devices, the user can check the latest frame (the preview camera image) of the moving image in real time when shooting the moving image. However, in this case, the recording camera image is generated using the processing result of the preview camera image. That is, the process of generating these camera images is shared.

Therefore, the image quality of the recording camera image of the captured moving image is the same as the image quality of the preview camera image of the moving image.

In such a conventional technique, the processing for generating the preview camera image prioritizes the processing time over the image quality, so that the processing result of the recording camera image is not sufficient image quality.

On the other hand, in such a conventional technique, since the processing time of the preview camera image is limited, it is not possible to select heavy processing as the processing of the recording camera image.

The second camera module 20 acquires a second camera image of the subjects 101, for example (FIG. 2) .

Furthermore, as shown in FIG. 2, for example, the electronic device 100 includes a global navigation satellite system (GNSS) module 40, a wireless communication module 41, a CODEC 42, a speaker 43, a microphone 44, a display module 45, an input module 46, an inertial measurement unit (IMU) 47, a main processor 48, and a memory 49.

The GNSS module 40 measures the current position of the electronic device 100, for example.

The CODEC 42 bidirectionally performs encoding and decoding, using a predetermined encoding/decoding method, as shown in FIG. 2 for example.

The speaker 43 outputs a sound in accordance with sound data decoded by the CODEC 42, for example.

The display module 45 displays predefined information. The display module 45 is, for example, a touch panel.

The input module 46 receives a user’s input (a user’s operations) . The input module 46 The input module 46 is included in, for example, the touch panel.

An IMU 47 detects, for example, the angular velocity and the acceleration of the electronic device 100.

The main processor 48 controls the global navigation satellite system (GNSS) module 40, the wireless communication module 41, the CODEC 42, the speaker 43, the microphone 44, the display module 45, the input module 46, and the IMU 47.

In the example of FIG. 2, the processor 103 is composed of the image signal processor 30 and the main processor 48. The processor 103 is defined as a controller that controls the imaging module 102 and acquires a camera image.

For example, the processor 103 controls the imaging module 102 to sequentially acquire camera images and depth images corresponding to a plurality of consecutive frames. Then, the processor 103 outputs the processed camera image (camera image data) by performing image processing on the acquired camera image based on the depth image.

The memory 49 stores a program and data required for the image processor 30 to control the first camera module 10 and the second camera module 20, acquired image data, and programs and data required for the main processor 48 to control the electronic device 100.

For example, the memory 49 includes a computer readable storage medium having a computer program stored thereon, wherein when the computer program is executed by the processor 103, the computer program implements a method for controlling the electronic device 100.

It is noticed that the images including such as the captured images and generated images exist in the form image data in the electronic device 100 (for, example, the data of the images are stored in the memory 49) . Furthermore, the processor 103 processes the images as image data.

Especially, for example, the memory 49 includes program code. The memory 49 and the program code configured to, with the processor 103, cause the electronic device 100 to perform: acquiring a camera image, to generate a moving image, by controlling an imaging module 102; acquiring a preview camera image based on the camera image, by a preview process; and acquiring a recording camera image based on the camera image, by a recording process, wherein the preview process and the recording process are executed separately by a processor 103.

Here, for example, as shown in FIG. 2, the electronic device 100 communicates with the external calculator (the sever) 200 via the wireless communication module 41.

For example, the processor 103 of the electronic device 100 causes the external calculator 200 to perform calculation processing of the predetermined data (information) , by transmitting predetermined data (information) to the external calculator 200 via the wireless communication module 41.

Then, the processor 103 of the electronic device 100 receives the data (information) calculated by the external calculator 200 from the calculator 200 via the wireless communication module 41.

The electronic device 100 having the above-described configuration is a mobile phone such as a smartphone in this embodiment, but may be other types of electronic devices (for instance, a tablet computer and a PDA) including the imaging module 102.

As described above, in the examples shown in FIGS. 1 and 2, the imaging module 102 includes the first camera module 10 and the second camera module 20. The first camera module 10 captures the subject 101 to acquire a first camera image. The second camera module 20 captures the subject 101 to acquire a second camera image.

In the examples shown in FIGS. 1 and 2, the processor 103 acquires the camera image based on the first camera image and the second camera image. Then, the processor 103 calculates the depth information corresponding to the camera image, and the processor 103 acquires the depth image corresponding to the camera image based on the calculated depth information.

However, the configuration of the imaging module 102 of the electronic device 100 is not limited to the configurations shown in FIGS. 1 and 2.

For example, FIG. 3 is a diagram showing another example of the imaging module 102 of the electronic device 100 shown in FIGS. 1 and 2.

Thus, instead of the examples shown in FIGS. 1 and 2, for example, as shown in FIG. 3, the imaging module 102 may only include a first camera module 10.

In the example shown in FIG. 3, the processor 103 calculates the depth information corresponding to the camera image, the processor 103 and acquires the depth image corresponding to the camera image based on the calculated depth information.

Next, FIG. 4 is a diagram showing still another example of the imaging module 102 of the electronic device 100 shown in FIGS. 1 and 2.

As shown in FIG. 4, the imaging module 102 may further include an additional camera module 50.

The additional camera module 50 shown in FIG. 4 captures the subject 101 and acquires a difference image (the event camera image) having pixel values due to changes over time in the captured camera image.

The additional camera module 50 is, for example, an event camera having a performance close to the shooting timing and FPS (Flames Per Second) of the imaging module 102.

Here, FIG. 5 illustrates a block diagram of the processor according to the embodiment of the present disclosure.

As shown in FIG. 5, the processor 103 shown in FIG. 5 may be substituted as an apparatus. The apparatus comprises: a camera image acquiring unit 103a configured to acquire a camera image, to generate a moving image, by controlling an imaging module 102; a preview camera image acquiring unit 103b configured to acquire a preview camera image based on the camera image, by a preview process; and a recording camera image acquiring unit 103c configured to acquire a recording camera image based on the camera image, by a recording process, wherein the preview process and the recording process are executed separately. In this case, the electronic device 100 may be represented as an apparatus including the processor 103.

Next, an example of a method of generating image data by the electronic device 100 having the above-described configuration and functions will now be described.

Hereinafter, the processing by the processor 103 of the electronic device 100 will be mainly described. In the example shown in FIG. 6 below, an example of generating a preview camera image and a recording camera image based on one camera image will be described.

Here, FIG. 6 is a diagram showing a first example of a flow for acquiring a preview camera image and a recording camera image, at the time of moving image shooting according to the embodiment of the present invention.

As shown in FIG. 6, the processor 103 captures a subject by controlling the imaging module 102 (S1) . Then, the processor 103 acquires a camera image in order to generate a moving image (S2) .

Then, the processor 103 acquires a preview camera image for previewing at the time of shooting the moving image based on the camera image by the preview process PA.

Furthermore, the processor 103 acquires a recording camera image for recording based on the camera image by the recording process PB.

In the example shown in FIG. 6, the processor 103 separately executes the preview process PA and the recording process PB.

In particular, the processor 103 executes the preview process PA and the recording process PB in parallel (simultaneously) .

More specifically, the processor 103 acquires the preview depth value based on the camera image in the preview process PA (the preview depth calculation process S3A) .

Then, the processor 103 acquires a preview depth image based on the preview depth value (the preview depth image acquisition process S4A) .

Then, the processor 103 generates a preview camera image by executing image processing on the camera image based on the preview depth image (the preview image processing process S5A) .

Then, the processor 103 executes the preview output process S6A that outputs the preview camera image in the preview process PA.

For example, the processor 103 causes the display module to display the preview camera image.

On the other hand, the processor 103 acquires a recording depth value based on the camera image in the recording process PB (the recording depth calculation process S3B) .

Then, the processor 103 acquires a recording depth image based on the recording depth value (the recording depth image acquisition process S4B) .

Then, the processor 103 generates a recording camera image by executing image processing on the camera image based on the recording depth image (the recording image processing process S5B) .

Then, in the recording process PB, the processor 103 executes the recording output process S6B for outputting the recording camera image.

For example, the processor 103 stores the recording camera image in the memory 49.

In this way, the responsiveness of the process of generating the preview camera image can be prioritized, and the heavy process of prioritizing the image quality can be applied to the generation of the recording camera image, by the processor 103 executing the preview process PA and the recording process PB separately in parallel.

Here, for example, the first amount of data of the camera image calculated by the processor 103 at the preview depth is set to be smaller than the second amount of data of the camera image calculated by the processor 103 at the recording depth.

In particular, the first calculation amount for the camera image on which the processor 103 executes the preview depth calculation is set lower than the calculation amount for of the camera image on which the processor 103 executes the recording depth calculation.

Therefore, the processor 103 can execute the process of generating the preview camera image faster.

For example, the processor 103 may cause an external calculator 200 shown in FIG. 2 to generate a recording camera image based on the camera image, in the recording process PB.

More specifically, in the recording process PB, the external calculator 200 acquires the recording depth value based on the camera image (the recording depth calculation process S3B) .

Then, the external calculator 200 acquires a recording depth image based on the recording depth value (recording depth image acquisition process S4B) .

Then, the external computer 200 generates a recording camera image by performing image processing on the camera image based on the recording depth image (the recording image processing process S5B) .

Then, the processor 103 acquires the recording depth image generated by the external computer 200.

In this case, the wireless communication module 41 shown in FIG. 2 transmits the camera image to the external calculator 200, and the wireless communication module 41 receives the recording camera image generated by the external calculator 200, in the recording process PB.

As a result, the amount of data processed by the processor 100 to generate the recording camera image can be reduced. Therefore, it is possible to improve the responsiveness of the process of generating the preview camera image, and it is possible to apply a heavy process that prioritizes the image quality to the generation of the recording camera image.

For example, the processing speed of the external calculator 200 shown in FIG. 2 is set to be faster than the processing speed of the processor 103.

As a result, in the external calculator 200, heavy processing that prioritizes image quality can be applied to the generation of the recording camera image.

[Modification example]

In the example shown in FIG. 6 described above, an example of generating a preview camera image and a recording camera image based on one camera image has been described. However, the present invention is not limited to this example, and the preview camera image and the recording camera image may be generated based on the two camera images (the main camera image and sub camera image) .

Therefore, an example of generating a preview camera image and a recording camera image based on two camera images (the main camera image and sub camera image) will be described below.

Here, FIG. 7 is a diagram showing a second example of a flow for acquiring a preview camera image and a recording camera image, at the time of moving image shooting according to the embodiment of the present invention.

In the example of FIG. 7, the main camera image and the sub camera image are acquired by the first camera module 10 and the second camera module 20 of the imaging module 102. Then, the processor 103 generates a preview camera image and a recording camera image based on these two camera images.

More specifically, first, as shown in FIG. 7, the processor 103 controls the imaging module 102 to image a subject in order to generate a moving image (S1R, S1L) . As a result, the processor 103 acquires the main camera image and the sub camera image (S2R, S2L) .

Then, in the preview process PA, the processor 103 acquires a preview depth value based on the main camera image and the sub camera image (the preview depth calculation process S3A) .

Then, the processor 103 acquires the preview depth image based on the preview depth value (the preview depth image acquisition process S4A) .

Then, the processor 103 generates a preview camera image by executing image processing on the main camera image based on the preview depth image (the preview image processing process S5A) .

On the other hand, in the recording process PB, the processor 103 acquires a recording depth value based on the main camera image and the sub camera image (the recording depth calculation process S3B) .

Then, the processor 103 acquires a recording depth image based on the recording depth value (recording depth image acquisition process S4B) .

Then, the processor 103 generates a recording camera image by executing image processing on the main camera image based on the recording depth image (the recording image processing process S5B) .

In this way, the responsiveness of the process of generating the preview camera image can be prioritized, and the heavy process of prioritizing the image quality can be applied to the generation of the recording camera image, thereby the processor 103 executes the preview process PA and the recording process PB in parallel and separately.

As described above, according to the electronic device according to the present invention, comprises: an imaging module configured to capture a camera image; at least one processor; and at least one memory including program code.

The processor executes the preview process and the recording process separately.

As a result, the responsiveness of the process of generating the preview camera image can be prioritized, and the heavy process of prioritizing the image quality can be applied to the generation of the recording camera image, thereby the processor executes the preview process and the recording process in parallel and separately.
