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 application.

In the description of the present application, it is noted that, unless explicitly stated or limited otherwise, "including" and "having" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The present application will be described in detail with reference to specific examples.
In one embodiment, as shown in fig. 1, a shooting parameter adjustment method is specifically proposed, which can be implemented by means of a computer program and can be run on a von neumann-based shooting parameter adjustment device. The computer program may be integrated into the application or may run as a separate tool-like application.
Specifically, the shooting parameter adjustment method includes:
s101: and acquiring a focus value corresponding to the shot image.
The Focus Value (FV) is a brightness Value of the captured image after the terminal focuses on the captured image area, and the distance of the capture distance can be determined by the Focus Value.
Specifically, the process of obtaining the focus value corresponding to the shot image is as follows: and acquiring the brightness value of each pixel point in the shot image, filtering the brightness value to obtain a filtering value, and calculating the focusing value based on the filtering value. The filtering of the brightness value is to filter out the pixel point brightness value with a larger numerical value, and eliminate the interference of too high local brightness in the shot image, so that the focus value is more accurately calculated. The filtering value refers to the pixel point brightness value remained after filtering the pixel point brightness value with larger numerical value
Calculating the focus value according to the following formula:
FV represents a focusing value corresponding to the shot image, Q (i) represents an ith filter value, and n represents the number of pixels corresponding to the filter value contained in the shot image.
S102: and when the focusing value is smaller than the focusing threshold value, adjusting the current light measuring mode of the terminal to be a central light measuring mode, and increasing the current sharpness level of the terminal to be a target sharpness level.
And when the focusing value is smaller than the focusing threshold value, judging that the shooting scene is a close-range shooting scene, wherein the terminal converts the focusing value into a distance parameter and displays the distance parameter on a terminal interface so as to be convenient for a user to understand. The focusing threshold is converted into a distance parameter threshold through the terminal and displayed on the terminal interface, and the distance parameter threshold can be manually set by a user or set by the terminal according to the self performance and the shooting general knowledge after the user selects automatic setting. An example of a possible distance parameter threshold setting is shown in fig. 2 a. The user may set the distance parameter threshold by inputting a numerical value, moving a slider, or clicking an adjustment button, or may select an "auto reference value" to set the distance parameter threshold by other components of the smartphone.
The light measuring mode is a mode of measuring the light intensity reflected by the object, and is divided into different light measuring modes according to the difference of the measured shooting range and distance in the shooting area, and the light measuring modes mainly include a spot light measuring mode, a center light measuring mode, an average light measuring mode and a multi-region light measuring mode. The point metering mode is that a metering element of the terminal only measures a small range of a specified shooting picture center, a shooting lens of the terminal is aligned to each part of a shooting object for multiple times during shooting, the brightness of the shooting object is measured successively, and the point metering mode is complex to operate and is suitable for shooting scenes with accurate measurement results and strict exposure requirements. The central light metering mode is a mode of metering light at the center of the shooting area accounting for about 60% of the shooting area and simultaneously taking account of the edge of a picture, and is suitable for multi-scene shooting. The average metering mode is a mode of measuring the average light brightness of the whole shooting area, and is suitable for scene shooting with little difference of picture light intensity. The multi-region metering mode is to divide a shooting region into regions and perform metering by each metering element corresponding to the divided regions, is suitable for shooting scenes with accurate measurement results, and has technical requirements on the metering elements and the structure of a terminal. Therefore, when the close-distance photographing is determined, the current metering mode is adjusted to the center metering mode by the terminal, so that the brightness of the photographed image is appropriate.
The sharpness refers to the planar definition of a photographed image and the contrast of the edge of the photographed image. Specifically, the process of adjusting the current sharpness level of the terminal to the target sharpness level is as follows: determining a target focusing range to which the focusing value belongs, and determining a target sharpness grade corresponding to the target focusing range according to the corresponding relation between different focusing ranges and different sharpness grades; adjusting a current sharpness level of the terminal up to the target sharpness level. The corresponding relation between different focusing ranges and different sharpness levels is determined by performance parameters of related elements in the terminal, so that the corresponding relation between different focusing ranges and different sharpness levels is different for different types and models of terminals. As shown in fig. 2b, taking a smart phone as an example, a possible sharpness level display interface includes a sharpness level corresponding to each focusing range, and the user can set the sharpness level by moving the slider.
Optionally, when the terminal adjusts the light metering mode and the sharpness level, a prompt message for adjusting the shooting parameters is sent to the user, as shown in fig. 2c, a prompt box pops up on the terminal for prompting "detecting the current close-distance shooting, adjusting the current light metering mode to the central light metering mode and adjusting the current sharpness level to the target sharpness level for better imaging effect", where the prompt message is a feasible prompt message for adjusting the shooting parameters. The user can accept the adjustment of the shooting parameters by clicking 'confirm' or reject the adjustment of the shooting parameters by clicking 'cancel'.
In the embodiment of the application, a focusing value corresponding to a shot image is obtained, when the focusing value is smaller than a focusing threshold value, the current light measuring mode of the terminal is adjusted to be a central light measuring mode, and the current sharpness level of the terminal is increased to be a target sharpness level. When the focusing value is smaller than the focusing threshold value, the current shooting scene is determined to be a close-distance shooting scene, the current light metering mode is adjusted to be the central light metering mode, the current sharpness level of the terminal is increased to be the target sharpness level, the brightness of the shot image is appropriate, the details are clear, the shooting rate of the shot image is increased, the shooting time is saved, and the user experience is enhanced.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating another embodiment of a shooting parameter adjustment method according to the present application. Specifically, the method comprises the following steps:
s201: and acquiring a focus value corresponding to the shot image.
See S101 for details, which are not described herein.
S202: and when the focus value is smaller than a focus threshold value, saving the current photometric mode and the current sharpness level.
And when the focusing value is smaller than the focusing threshold value, determining that the current shooting scene is a close-distance shooting scene, and storing the current photometry mode and the current sharpness level, thereby avoiding that corresponding shooting parameters cannot be set in other shooting scenes.
Specifically, one possible method for saving the current photometry mode and the current sharpness level is as follows: the current light metering mode and the current sharpness level are stored in a nonvolatile memory of the terminal as user data, where the nonvolatile memory (NVM) can still store data after a power supply is cut off, and the data includes but is not limited to any one of a read-only memory (ROM), a programmable read-only memory (PROM), an electrically alterable read-only memory (EAROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), and a flash memory.
S203: and adjusting the current light measuring mode of the terminal to be a central light measuring mode, and increasing the current sharpness level of the terminal to be a target sharpness level.
See S102 for details, which are not described herein.
S204: when the focus value is larger than the focus threshold value, the central light metering mode is adjusted to the current light metering mode, and the target sharpness level is decreased to the current sharpness level.
When the focus value is larger than the focus threshold value, it is determined that the shooting scene is a non-close-distance shooting scene, and therefore, the central metering mode is adjusted to the current metering mode, and the target sharpness level is adjusted to the current sharpness level, so that the terminal performs appropriate shooting parameter configuration.
Optionally, when it is determined that the shooting scene is a non-close-distance shooting scene, the process of adjusting the shooting parameters is as follows: reading the user data in the nonvolatile memory, determining the current metering mode and the current sharpness level according to the user data, adjusting the central metering mode to the current metering mode, and adjusting the target sharpness level to the current sharpness level, so that the terminal performs appropriate shooting parameter configuration.
In this embodiment of the present application, the current metering mode and the current sharpness level are saved, and when the focus value is greater than the focus threshold, the central metering mode is adjusted to the current metering mode, and the target sharpness level is adjusted to the current sharpness level. The method can determine that the current shooting scene is a close-distance shooting scene when the focusing value is larger than the focusing threshold value, adjust the central light metering mode to the current light metering mode, adjust the target sharpness level to the current sharpness level, recover the original shooting parameter setting, avoid the situation that the corresponding shooting parameters cannot be set in other shooting scenes, enable the brightness of the shot image to be proper and the details to be clear, thereby increasing the shooting rate of the shot image, saving the shooting time and enhancing the user experience.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating another embodiment of a shooting parameter adjustment method according to the present application. Specifically, the method comprises the following steps:
s301: and acquiring a focus value corresponding to the shot image.
See S101 for details, which are not described herein.
S302: and when the focusing value is smaller than the focusing threshold value, judging whether the current light metering mode is the central light metering mode.
The light measuring modes mainly include a point light measuring mode, a center light measuring mode, an average light measuring mode and a multi-region light measuring mode. The central photometry mode is suitable for multi-scene shooting, and therefore, will the photometry mode is adjusted to before the central photometry mode, judge whether the current photometry mode does the central photometry mode, if the current photometry mode does the central photometry mode, then the photometry mode does not need to be adjusted, thereby making the operation more simple and convenient.
S303: and if the current light measuring mode is the central light measuring mode, keeping the setting of the central light measuring mode, and increasing the current sharpness level of the terminal to be the target sharpness level.
When the current light metering mode is judged to be the central light metering mode, the light metering mode does not need to be adjusted, and the setting of the central light metering mode is maintained.
Optionally, when the terminal maintains the setting of the light metering mode and adjusts the sharpness level, a prompt message for adjusting the shooting parameters is sent to the user, as shown in fig. 5, a prompt message for feasible shooting parameter adjustment pops up a prompt box on the terminal, and prompts "detect current close-distance shooting, and adjust the current sharpness level to the target sharpness level for better imaging effect and maintaining the setting of the central light metering mode". The user can accept the adjustment of the shooting parameters by clicking 'confirm' or reject the adjustment of the shooting parameters by clicking 'cancel'.
Wherein, the current sharpness level of the terminal is adjusted to the target sharpness level, which may be referred to as S102 specifically and is not described herein again.
S304: and if the current light metering mode is not the central light metering mode, adjusting the light metering mode to be the central light metering mode, and increasing the current sharpness level of the terminal to be the target sharpness level.
See S102 for details, which are not described herein.
In this application embodiment, judge whether current photometry mode does the central photometry mode, if the current photometry mode does the central photometry mode, then keep the setting of central photometry mode, if the current photometry mode is not the central photometry mode, then will the photometry mode adjusts to central photometry mode. Can judge the current mode of photometry, if the current mode of photometry does the mode of photometry is surveyed to the center, then need not adjust the mode of photometry, avoids the terminal is repeated adjusts the step of shooing the parameter to it is more simple and convenient to make the operation.
