That is, the processor or the electronic device may implement the shooting method provided by the embodiment of the present invention by running the software program in the android operating system.
The electronic equipment in the embodiment of the invention can be a mobile terminal or a non-mobile terminal. For example, the mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile terminal may be a Personal Computer (PC), a Television (TV), a teller machine or a self-service machine, and the like, and the embodiment of the present invention is not particularly limited.
The executing subject of the shooting method provided by the embodiment of the present invention may be the electronic device, or may also be a functional module and/or a functional entity capable of implementing the shooting method in the electronic device, which may be determined specifically according to actual use requirements, and the embodiment of the present invention is not limited. The following takes an electronic device as an example to exemplarily describe the shooting method provided by the embodiment of the invention.
The following describes an exemplary photographing method according to an embodiment of the present invention with reference to the drawings.
As shown in fig. 2, an embodiment of the present invention provides a photographing method, which may include steps 201 to 203 described below.
The electronic equipment can acquire the first preview image under the condition that a shooting preview interface is displayed.
In the embodiment of the invention, if a user shoots in a scene with dark ambient light, or shoots by supplementing light or shoots a lightning picture, the user can trigger the electronic equipment to start an optical shutter mode, and in the optical shutter mode, the electronic equipment displays a shooting preview interface, collects a preview image of a shooting object in real time, and caches the collected preview image in the electronic equipment.
In the embodiment of the invention, the electronic equipment can collect one frame of preview image, then cache the one frame of preview image, collect the next frame of preview image, and then cache the next frame of preview image; or multiple frames of preview images can be collected and then buffered. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
The brightness difference value is a difference value between the brightness of the first preview image and the brightness of the second preview image, and the second preview image is an image acquired by the electronic device within a preset time before the first preview image is acquired.
In this embodiment of the present invention, the brightness threshold may be a brightness threshold set for a change in light intensity caused by a flash of an external flash, or may be a brightness threshold set for a change in light intensity caused by a flash of a flash, or may be a brightness threshold set for a change in light intensity caused by any other possible flash, which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.
For example, when the electronic device is used in combination with an external flash during shooting, the brightness threshold may be a threshold determined based on a power value (e.g., a rated power value) of the external flash and a distance value between the external flash and a shooting object. Specifically, if the acquired preview image has a larger brightness and the brightness difference is greater than the brightness threshold value compared with the previously acquired preview image, it may be determined that the external flash flashes in the shooting preview process.
As another example, the brightness threshold may be a threshold determined based on a large amount of experimental data of the lightning intensity, for example, when the electronic device captures a lightning picture. Specifically, if the acquired preview image has a larger brightness and the brightness difference is greater than the brightness threshold value compared with the previously acquired preview image, it can be determined that a lightning flash exists in the shooting preview process.
In this embodiment of the present invention, if the electronic device detects that the brightness of the first preview image is greater than the brightness of the second preview image, and the brightness difference between the two images is greater than the brightness threshold, the electronic device may continue to perform step 203 described below. If the electronic device detects that the brightness of the first preview image is less than or equal to the brightness of the second preview image, the electronic device returns to continue executing the step 201; or if the electronic device detects that the brightness of the first preview image is greater than the brightness of the second preview image and the brightness difference between the two images is less than or equal to the brightness threshold, the electronic device returns to continue to execute step 201.
Optionally, in a possible implementation manner, assuming that the electronic device captures a lightning picture, the electronic device may detect whether the difference between the brightness of the two preview images satisfies the brightness difference condition, and may also detect whether the difference between the vertical edge points of the two preview images satisfies the position difference condition. In this case, the step 202 can be specifically realized by the step 202a described below.
Step 202a, the electronic device detects whether the brightness of the first preview image is greater than the brightness of the second preview image, whether the brightness difference is greater than a brightness threshold, and whether the target position difference is greater than a position threshold.
And the target position difference is the position difference between the vertical edge point of the first preview image and the vertical edge point of the second preview image.
In this embodiment of the present invention, the electronic device may identify the first preview image, and detect whether the identified image has a corresponding feature of a vertical edge point (an image feature corresponding to a lightning flash), specifically, if it is detected that a bright spot (an image feature corresponding to a lightning flash) exists in an edge region along the vertical direction in the identified image, the electronic device may determine the bright spot in the edge region as the vertical edge point. Similarly, the detection method of the vertical edge point of the second preview image and the detection method of the vertical edge point of the first preview image are not described herein again.
It should be noted that the position difference between the vertical edge points in the two frames of preview images may be a position difference between upper edge points in the two frames of preview images, or may be a position difference between lower edge points in the two frames of preview images, or may be a distance difference between connecting lines of the upper edge points and the lower edge points in the two frames of preview images. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
In this embodiment of the present invention, if the electronic device detects that the brightness of the first preview image is greater than the brightness of the second preview image, the brightness difference between the two images is greater than the brightness threshold, and the target position difference is greater than the position threshold, it may be determined that there is a lightning flash, and then the electronic device may continue to perform step 203 described below.
If the electronic device detects that the brightness of the first preview image is less than or equal to the brightness of the second preview image, the electronic device returns to continue executing the step 201; or if the electronic device detects that the brightness of the first preview image is greater than the brightness of the second preview image and the brightness difference between the two images is less than or equal to the brightness threshold, the electronic device returns to continue to execute the step 201; or if the electronic device detects that the brightness of the first preview image is greater than the brightness of the second preview image, the brightness difference between the two images is greater than the brightness threshold, and the target position difference is less than or equal to the position threshold, the electronic device returns to continue to execute step 201.
And step 203, the electronic equipment executes shooting action to obtain a target image.
In the embodiment of the invention, when the electronic device detects that the acquired preview image has larger brightness and the brightness difference value is larger than the brightness threshold value compared with the previously acquired preview image, it can be considered that the external flash or the flash exists in the shooting preview process, and at this time, the electronic device can execute the shooting action to obtain the target image.
Specifically, for a scene of external flash lamp flashing, the flash lamp mode of a light shutter of the electronic equipment corresponds to; for a scene of lightning flash, the lightning pattern of the optical shutter of the electronic device is corresponded. In different modes, the brightness thresholds are different.
The specific implementation manners of the shooting method provided by the embodiment of the invention in the scene of flash of the external flash lamp and in the scene of flash are respectively described below through a first implementation manner and a second implementation manner.
First implementation
In a first implementation, a user may select a flash mode of a light shutter of the electronic device and the capture enters a preview phase. Then, the electronic device may acquire the power value of the external flash and the distance value between the flash and the photographic subject.
The power value and/or the distance value may be input by a user, or may be automatically obtained by the electronic device, and may be determined according to an actual use requirement, which is not limited in the embodiment of the present invention.
For example, assuming that the external flash and the electronic device are independent of each other (i.e., no communication is established), the user may manually input the power value of the external flash and the distance value between the external flash and the photographic subject on the electronic device.
Further, in the shooting preview stage, the electronic device detects the brightness change condition of the preview image along with the scene environment in real time, and if the brightness of the obtained preview image is larger than that of the previously obtained preview image and the brightness difference value suddenly exceeds the brightness threshold value, the flash lamp can be considered to be on. Once the electronic device detects the flash, the electronic device opens the shutter to take a picture, and a frame of image is obtained.
In the embodiment of the invention, the electronic equipment can fully utilize the photographic external flash lamp to shoot high-quality images under the condition of not increasing other external devices (such as a flash initiator); because the flash lamp is not required to be led through the flasher, the hardware configuration cost of the electronic equipment can be reduced.
Second implementation
In a second implementation, a user may select a lightning mode of a light shutter of the electronic device and the shooting enters a preview phase. In the shooting preview stage, the electronic equipment detects the image characteristics of the current preview image, and if the lightning matching characteristics appear in the preview image, the electronic equipment considers lightning flashing.
Specifically, the electronic equipment performs vertical edge detection on the preview image, records position coordinates of edge points, and counts the average brightness value of the edge detection points; and calculating the position difference and the average brightness difference of the vertical edge points of the adjacent frame images. A lightning flash may be deemed to be present if the electronic device determines that the difference in the vertical edge point positions of the current frame image and the previous frame image exceeds a position threshold and the difference in brightness exceeds a brightness threshold.
Furthermore, when the electronic device detects a lightning flash in the preview image, the electronic device automatically starts a camera shutter to shoot, so as to obtain a frame of image.
In the embodiment of the invention, the lightning picture can be easily shot, and the experience of shooting the image by the electronic equipment can be improved.
Optionally, in the embodiment of the present invention, a strobe mode of the flash lamp may be set (that is, the flash lamp flashes once every preset time, that is, flashes for a preset time within a preset time), and the strobe mode of the flash lamp is synchronously set to the electronic device. In this strobe mode, the electronic device can capture the strobe effect of the flash lamp, i.e., capture the effect of multiple exposures with one exposure. Therefore, the shooting effect of the electronic equipment for shooting the image can be improved.
According to the shooting method provided by the embodiment of the invention, the first preview image can be obtained; executing a shooting action to obtain a target image under the condition that the brightness of the first preview image is greater than that of the second preview image and the brightness difference value between the first preview image and the second preview image is greater than a brightness threshold value; the second preview image is an image acquired by the electronic equipment within a preset time before the first preview image is acquired. The shooting method provided by the embodiment of the invention can be applied to a scene shot by the electronic equipment, once the electronic equipment detects that the obtained preview image has larger brightness and the brightness difference value is larger than the brightness threshold value compared with the previously obtained preview image, the flash lamp can be judged to flash, the electronic equipment instantly starts automatic shooting to obtain an image with better light supplement effect, and an external flash lamp is not required to flash through a flash initiator in the shooting process, so that the electronic equipment is not required to be provided with the flash initiator, and the hardware configuration cost of the electronic equipment can be reduced.
Optionally, in the embodiment of the present invention, as shown in fig. 3 with reference to fig. 2, before step 201 described above, the shooting method provided in the embodiment of the present invention further includes step 204 and step 205 described below.
And step 204, the electronic equipment acquires a target power value and a target distance value of the external flash lamp.
The target distance value is a distance value between the external flash lamp and the shooting object. The first preview image is a preview image of the subject.
Step 205, the electronic device determines a brightness threshold according to the target power value and the target distance value.
In the embodiment of the invention, a functional relationship F between the power of the external flash lamp (denoted as P), the distance between the external flash lamp and the shooting object (denoted as D), and the average brightness change value of the image when the flash lamp is turned on from off when the electronic device shoots (denoted as Δ L) can be calibrated in advance according to experimental data:
ΔL＝F(P，D)。
specifically, in the case of shooting with the electronic device combined with the external flash, in the shooting preview stage, after acquiring the power value of the external flash (for example, P1) and the distance value between the external flash and the shooting object (for example, D1), the electronic device may calculate the average brightness change value (for example, Δ L1) according to the above functional relationship. It is to be understood that the average luminance change value Δ L1 may be used as the luminance threshold value, i.e., a reference value for detecting the flash.
In the embodiment of the invention, the corresponding brightness threshold value can be determined based on the known power of the external flash lamp and the distance value between the external flash lamp and the shooting object according to the functional relation, so that the flash lamp brightness is detected in shooting, and the shooting action is controlled, thereby improving the accuracy and intelligence of the electronic equipment for controlling shooting.
In the embodiment of the present invention, as shown in fig. 4 with reference to fig. 3, after step 205 described above, the shooting method provided in the embodiment of the present invention further includes step 206 and step 207 described below. Accordingly, the step 203 can be specifically realized by the step 203a described below.
And step 207, the electronic equipment acquires a target exposure parameter according to the environment brightness value and the brightness threshold value.
And 203a, the electronic equipment executes shooting action by adopting the target exposure parameters to obtain a target image.
In the embodiment of the invention, in the shooting preview stage, the electronic device can detect the environmental brightness value (recorded as L2), and calculate the corresponding exposure parameter EV (log) by combining the brightness change value Δ L1 of the flash lamp2(L2+ Δ L1). Furthermore, the electronic device can use the exposure parameter to execute a shooting action to obtain a frame of image. Therefore, high-quality images can be shot under proper exposure parameters, and the image effect shot by the electronic equipment can be improved.
Optionally, in the embodiment of the present invention, as shown in fig. 5 with reference to fig. 2, after step 203 described above, the shooting method provided in the embodiment of the present invention further includes step 208 described below.
And step 208, the electronic equipment stores one of the first preview image and the target image, which meets the preset condition, into a target storage space of the electronic equipment.
The preset condition may be a determination condition for determining a low imaging quality in the two images. The preset condition may include at least one of: the image brightness is larger, and the image resolution is higher. It should be noted that the preset condition may also be any other possible condition, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited.
In the embodiment of the invention, the electronic equipment can compare the first preview image with the target image, the image meeting the preset condition after comparison is the image with better imaging quality, and the image is stored in the target storage space of the electronic equipment.
On one hand, taking the example of the electronic device combining with the external flash lamp for shooting, considering that the shooting may not be started when the flash lamp flash is detected in the preview image, and therefore, in order to improve the probability of obtaining the flash lamp effect, the electronic device may obtain the cached preview image sequence from the camera cache space thereof. Furthermore, the electronic device can select an image with a flash fill-in effect from the target image obtained by shooting and the cached preview image sequence.
If the electronic equipment detects that the average brightness value of a certain preview image in the cached preview image sequence is matched with (equal to or approximately equal to) the average brightness value of the image when the flash is detected during previewing, the preview image is considered to be an image with a flash fill effect, and the preview image is stored in the album storage space.
On the other hand, taking the example of the electronic device capturing the lightning picture, considering that there is a possibility that the lightning picture cannot be captured when the electronic device re-starts capturing when the lightning flash is detected in the preview image, in order to increase the probability of capturing the lightning picture, the electronic device may obtain a cached preview image sequence from a camera cache space of the electronic device, and pick out an image with a lightning characteristic from a target image obtained by capturing and the cached preview image sequence.
Specifically, if the electronic device detects that the vertical edge position and the average brightness value of the edge point of a certain preview image in the cached preview image sequence are matched with (equal to or approximately equal to) the vertical edge position and the average brightness value when the lightning flash is detected during previewing, the electronic device may determine that the lightning image exists in the preview image, and store the preview image in the album storage space.
Optionally, in the embodiment of the present invention, as shown in fig. 6 with reference to fig. 2, after step 203 described above, the shooting method provided in the embodiment of the present invention further includes step 209 described below.
And step 209, the electronic equipment generates a target dynamic image according to the second preview image, the first preview image and the target image.
Optionally, in this embodiment of the present invention, the electronic device may further generate a target dynamic image according to more images including the second preview image, the first preview image, and the target image. For example, the electronic device may generate a target dynamic image from the preview image, the second preview image, the first preview image, and the target image acquired before acquiring the second preview image; or the electronic device may generate a target dynamic image according to the second preview image, the first preview image, the target image, and an image acquired after the target image is acquired; alternatively, the electronic device may generate the target moving image from a preview image acquired before acquiring the second preview image, the first preview image, the target image, and an image acquired after acquiring the target image. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
In the embodiment of the invention, the super slow motion of the lightning mode can be set, namely, under the condition that the electronic equipment detects the lightening flash of lightning, the electronic equipment acquires the cached preview image sequence from the camera cache space and records the dynamic image by adopting the cached preview image sequence, so that the effect of the super slow motion of the lightning can be shot. Therefore, the experience of shooting images by the electronic equipment can be improved.
