The invention provides a parameter compensation method and device, which can effectively improve the preview effect of a shooting device in a low-light state. The following are detailed below.
Referring to fig. 1, fig. 1 is a schematic flow chart of a parameter compensation method according to an embodiment of the present invention, and the method of the present invention can be applied to a terminal configured with a camera, such as a mobile phone, a tablet computer, or a Personal Digital Assistant (PDA). The parameter compensation method shown in fig. 1 may include the following steps.
S101: when the shooting device is started, whether the current light state is a preset low light state or not is detected.
In an embodiment, whether the shooting device is started or not may be detected, and when the shooting device is detected to be started, it is triggered to determine whether the light state of the current environment is the preset low light state, for example, when the shooting device is started, it is detected whether the light state of the current environment is the low light state by obtaining a corresponding photosensitivity value of the shooting device in the current environment.
S102: and if the low light state is detected, acquiring the current value of the image parameter of the current acquired image of the shooting device.
In a specific embodiment, when the current light state is detected to be a low light state, a value of an image parameter corresponding to a currently acquired image of the shooting device, that is, the current value, may be obtained, so as to determine whether parameter compensation needs to be performed on the image parameter according to the current value of the image parameter, thereby improving a preview effect. Optionally, the image parameter may include parameters such as contrast, sharpness, and the like, and the embodiment of the present invention is not limited.
S103: and detecting whether the current value is lower than a preset parameter threshold value.
The preset parameter threshold is a preset threshold corresponding to the image parameter. For example, if the image parameter is contrast, the parameter threshold is a preconfigured contrast threshold; if the image parameter is sharpness, the parameter threshold is a preset sharpness threshold.
S104: and if the value is lower than the parameter threshold, adjusting the value of a screen parameter corresponding to the image parameter in the terminal screen parameter, wherein the adjusted screen parameter is used for compensating the image parameter.
In the existing practical application, under the condition of low light at night, the image parameters of the image collected by the shooting device are reduced, if the preview image is the contrast of the collected image is reduced, the preview effect is poor. And when detecting that the current value of the image parameter corresponding to the shooting device is lower than the parameter threshold value corresponding to the image parameter, the embodiment of the invention can compensate the image parameter corresponding to the shooting device by correspondingly adjusting the value of the terminal screen parameter, for example, increasing the value of the screen parameter corresponding to the image parameter in the terminal screen parameter, thereby improving the preview effect of the shooting device.
By implementing the embodiment of the invention, whether the current light state is the low light state or not can be detected when the shooting device is started, the current value of the image parameter of the current collected image is obtained when the current value is detected to be lower than the preset parameter threshold value, the compensation of the image parameter can be realized by adjusting the value of the screen parameter corresponding to the image parameter in the terminal screen parameter, and the preview effect of the shooting device can be effectively improved in the low light state.
Referring to fig. 2, fig. 2 is a schematic flow chart of another parameter compensation method according to an embodiment of the present invention, and specifically, the parameter compensation method according to the embodiment of the present invention may include the following steps.
S201: when the shooting device is started, the sensitivity information of the shooting device in the current light state is obtained, and the sensitivity information comprises a sensitivity value.
In a specific embodiment, whether parameter compensation needs to be performed on image parameters corresponding to a currently acquired image is further determined by detecting whether the shooting device is started and triggering to determine whether the light state of the current environment is a preset low-light state when the shooting device is detected to be started.
Furthermore, a parameter compensation function key can be preset for turning on or off the parameter compensation function of the embodiment of the invention. Before the sensitivity information of the shooting device in the current light state is obtained, whether the parameter compensation function is started or not can be detected, specifically, a user can start (or close) the parameter compensation function by clicking or double clicking or long pressing the function key, and when the parameter compensation function is detected to be started, the speed information of the shooting device in the current light state can be triggered to be obtained, so that whether parameter compensation is needed or not is determined currently.
S202: and judging whether the photosensitivity value exceeds a preset photosensitivity threshold value.
S203: and determining the current light state as a preset low light state.
In an embodiment, a sensitivity threshold may be preset as a basis for detecting whether the current light state is a low light state. When the starting of the shooting device is detected, if a user opens a certain installed shooting application in the terminal, the terminal can acquire sensitivity information including a sensitivity value corresponding to the current environment of the shooting device, the sensitivity value is compared with the preset sensitivity threshold, and the current light state can be determined to be a low light state when the sensitivity value exceeds the sensitivity threshold. Specifically, for example, the sensitivity ISO threshold is set to 1200, and when the photographing device is started, if it is detected that the acquired sensitivity ISO value exceeds 1200, the current light state may be determined as the low light state.
S204: and acquiring the current value of the image parameter of the current acquired image of the shooting device.
In a specific embodiment, when the current light state is detected to be a low light state, a value of an image parameter corresponding to a currently acquired image of the shooting device, that is, the current value, may be obtained, so as to determine whether parameter compensation needs to be performed on the image parameter according to the current value of the image parameter, thereby improving a preview effect. If the current light state is not detected to be a low light state, no processing may be performed.
Optionally, the image parameter may include parameters such as contrast, sharpness, and the like, and the embodiment of the present invention is not limited.
S205: and detecting whether the current value is lower than a preset parameter threshold value.
The preset parameter threshold is a preset threshold corresponding to the image parameter. For example, if the image parameter is contrast, the parameter threshold is a preconfigured contrast threshold; if the image parameter is sharpness, the parameter threshold is a preset sharpness threshold.
S206: and adjusting the value of a screen parameter corresponding to the image parameter in the terminal screen parameter, wherein the adjusted screen parameter is used for compensating the image parameter.
When ISO >1200 is in a low light state, some image parameters will be reduced, the preview effect of the camera starts to be reduced, and the camera cannot be dynamically adjusted at this time, so that the preview effect of the camera can be compensated by dynamically adjusting terminal screen parameters such as LCD (Liquid Crystal Display) parameters. In a specific embodiment, when it is detected that the current value of the image parameter corresponding to the shooting device is lower than the parameter threshold corresponding to the image parameter, the value of the terminal screen parameter, such as the parameter of the LCD screen, may be adjusted correspondingly, for example, the value of the parameter corresponding to the image parameter in the LCD screen parameter is increased, so as to compensate the image parameter corresponding to the shooting device, and improve the preview effect of the shooting device. If the current value of the image parameter is detected to be not lower than the parameter threshold corresponding to the image parameter, no processing is performed.
Optionally, if the image parameter may be saturation, the parameter threshold is a saturation threshold; the adjusting of the value of the screen parameter corresponding to the image parameter in the terminal screen parameter may specifically be: and increasing the saturation value of the terminal screen, wherein the increased saturation value of the terminal screen is used for compensating the saturation of the currently acquired image.
Further optionally, the image parameter may also be sharpness, and then the parameter threshold is a sharpness threshold; the adjusting of the value of the screen parameter corresponding to the image parameter in the terminal screen parameter may specifically be: and increasing the sharpness value of the terminal screen, wherein the increased sharpness value of the terminal screen is used for compensating the sharpness value of the currently acquired image.
Specifically, when the value of the screen parameter corresponding to the image parameter in the terminal screen parameter is adjusted to compensate the image parameter, the difference between the parameter threshold and the current value of the image parameter may be used as the adjustment value of the corresponding screen parameter in the terminal to compensate the image parameter; or the image parameters in the low light state may be compensated according to the preset image parameters of the shooting device and the associated screen parameters thereof, which is not limited in the embodiment of the present invention. For example, values of image parameters (exemplified by contrast) of the preview image corresponding to the photographing device in different light states (mainly, in a low light state with different ISO values) may be obtained in advance, and the contrast value of the LCD screen is sequentially increased according to a preset increase value to compensate the contrast corresponding to the photographing device in the light state until a best preview effect in the light state is trained, and at this time, the adjusted contrast value of the LCD screen corresponding to the best preview effect may be determined. And then, performing associated storage on the contrast value corresponding to the shooting device in the light state and the LCD screen contrast value corresponding to the optimal preview effect, further, simultaneously storing the ISO value corresponding to the light state, and then, for the low-light states with different ISO values, inquiring to obtain the associated LCD screen contrast value according to the stored contrast value and/or ISO value corresponding to the shooting device, adjusting the terminal LCD screen contrast value according to the associated LCD screen contrast value, and increasing the LCD screen contrast value to be not lower than the associated LCD screen contrast value so as to realize the compensation of the contrast corresponding to the shooting device.
S207: and when the shooting device is detected to be withdrawn, restoring the value of the screen parameter corresponding to the image parameter in the terminal screen parameter to the value before the adjustment.
Furthermore, when the shooting device is detected to be withdrawn, the terminal can perform parameter recovery operation on the screen parameter, and the value of the adjusted screen parameter is recovered to the value before the adjustment. Specifically, when ISO <1200, that is, the photosensitivity value is lower than the preset photosensitivity threshold, and the current light state is not the low-light state, it may indicate that the photographing device is in the normal state, and at this time, the adjusted parameters of the LCD screen may be restored to the original parameter values, and no additional compensation is required for the image parameters.
In the embodiment of the invention, the terminal can detect whether the current light state is the low light state when the shooting device is started, and acquire the current values of the image parameters of the currently acquired image, such as the contrast or the sharpness, when the current contrast value is detected to be lower than the preset contrast threshold or the current sharpness value is detected to be lower than the preset sharpness threshold, the contrast value or the sharpness value in the terminal screen parameters is correspondingly increased, so that the compensation of the image parameters of the shooting device, such as the contrast or the sharpness, is realized, and the preview effect of the shooting device can be effectively improved in the low light state.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a parameter compensation apparatus according to an embodiment of the present invention, which may be specifically installed in a terminal configured with a camera, such as a mobile phone, a tablet computer, or a PDA. Specifically, the parameter compensation device may include a state detection module 11, an acquisition module 12, a parameter detection module 13, and a parameter adjustment module 14. Wherein,
the state detection module 11 is configured to detect whether a current light state is a preset low light state when the shooting device is started.
In an embodiment, the state detection module 11 may detect whether the light state of the current environment is the low light state by detecting whether the shooting device is started and triggering to determine whether the light state of the current environment is the preset low light state when detecting that the shooting device is started, for example, the state detection module 11 may detect whether the light state of the current environment is the low light state by obtaining a photosensitivity value corresponding to the current environment of the shooting device when the shooting device is started.
The obtaining module 12 is configured to obtain a current value of an image parameter of a currently acquired image of the shooting device when the state detecting module 11 detects that the current light state is the low light state.
In a specific embodiment, when the state detection module 11 detects that the current light state is a low light state, the value of the image parameter corresponding to the currently acquired image of the shooting device, that is, the current value, may be obtained through the obtaining module 12, so as to determine whether parameter compensation needs to be performed on the image parameter according to the current value of the image parameter, thereby improving the preview effect. Optionally, the image parameter may include parameters such as contrast, sharpness, and the like, and the embodiment of the present invention is not limited.
The parameter detecting module 13 is configured to detect whether the current value obtained by the obtaining module 12 is lower than a preset parameter threshold.
The preset parameter threshold is a preset threshold corresponding to the image parameter. For example, if the image parameter is contrast, the parameter threshold is a preconfigured contrast threshold; if the image parameter is sharpness, the parameter threshold is a preset sharpness threshold.
The parameter adjusting module 14 is configured to adjust a value of a screen parameter corresponding to the image parameter in a terminal screen parameter when the parameter detecting module 13 detects that the current value is lower than the parameter threshold, where the adjusted screen parameter is used to compensate the image parameter.
In a specific embodiment, when the parameter detecting module 13 detects that the current value of the image parameter corresponding to the shooting device is lower than the parameter threshold corresponding to the image parameter, the parameter adjusting module 14 may adjust the value of the terminal screen parameter correspondingly, for example, increase the value of the screen parameter corresponding to the image parameter in the terminal screen parameter, to compensate the image parameter corresponding to the shooting device, so as to improve the preview effect of the shooting device.
By implementing the embodiment of the invention, whether the current light state is the low light state or not can be detected when the shooting device is started, the current value of the image parameter of the current collected image is obtained when the current value is detected to be lower than the preset parameter threshold value, the compensation of the image parameter can be realized by adjusting the value of the screen parameter corresponding to the image parameter in the terminal screen parameter, and the preview effect of the shooting device can be effectively improved in the low light state.
Further, referring to fig. 4, fig. 4 is a schematic structural diagram of another parameter compensation apparatus according to an embodiment of the present invention, and specifically, the apparatus may include a state detection module 11, an acquisition module 12, a parameter detection module 13, and a parameter adjustment module 14 of the parameter compensation apparatus. Further, in the embodiment of the present invention, the status detecting module 11 may include:
the information acquisition unit 111 is used for acquiring sensitivity information of the shooting device in a current light state when the shooting device is started, wherein the sensitivity information comprises a sensitivity value;
a determining unit 112, configured to determine whether the sensitivity value acquired by the information acquiring unit 111 exceeds a preset sensitivity threshold;
a state determining unit 113, configured to determine the current light state as a preset low light state when the determination result of the determining unit 112 is that the photosensitivity value exceeds the sensitivity threshold.
In a specific embodiment, a preset sensitivity threshold is stored in the terminal and used as a basis for detecting whether the current light state is a low light state. When it is detected that the photographing apparatus is started, for example, when a user opens a certain installed photographing application in the terminal, the information obtaining unit 111 may obtain sensitivity information corresponding to the current environment of the photographing apparatus, and compare the sensitivity information with the preset sensitivity threshold through the determining unit 112, and when the sensitivity information exceeds the sensitivity threshold, the state determining unit 113 may determine the current light state as the low light state. Specifically, for example, the sensitivity ISO threshold is set to 1200, and when the photographing device is started, if the determination unit 112 detects that the acquired sensitivity ISO value exceeds 1200, the state determination unit 113 may determine the current light state as the low light state.
Optionally, if the image parameter may be saturation, the parameter threshold is a saturation threshold; the parameter adjusting module 14 may be specifically configured to:
when the parameter detection module 13 detects that the saturation value of the currently acquired image is lower than the saturation threshold, the saturation value of the terminal screen is increased, wherein the increased saturation value of the terminal screen is used for compensating the saturation of the currently acquired image.
Optionally, the image parameter may also be sharpness, and then the parameter threshold is a sharpness threshold; the parameter adjustment module may specifically 14 be configured to:
when the parameter detection module 13 detects that the sharpness value of the currently acquired image is lower than the sharpness threshold, the sharpness value of the terminal screen is increased, wherein the increased sharpness value of the terminal screen is used for compensating the sharpness value of the currently acquired image.
When ISO >1200 is in a low light state, some image parameters will decrease, the preview effect of the camera starts to decrease, and the camera cannot be dynamically adjusted at this time, so that the preview effect of the camera can be compensated by dynamically adjusting terminal screen parameters such as those of the LCD screen. In a specific embodiment, when it is detected that the current value of the image parameter corresponding to the shooting device is lower than the parameter threshold corresponding to the image parameter, the value of the terminal screen parameter, such as the parameter of the LCD screen, may be adjusted correspondingly, for example, the value of the parameter corresponding to the image parameter in the LCD screen parameter is increased, so as to compensate the image parameter corresponding to the shooting device, and improve the preview effect of the shooting device.
Specifically, when the parameter adjusting module 14 adjusts the value of the screen parameter corresponding to the image parameter in the terminal screen parameter to compensate the image parameter, the difference between the parameter threshold and the current value of the image parameter may be used as the adjustment value of the corresponding screen parameter in the terminal to compensate the image parameter; or the image parameters in the low light state may be compensated according to the preset image parameters of the shooting device and the associated screen parameters thereof, which is not limited in the embodiment of the present invention. For example, the parameter adjusting module 14 may obtain values of image parameters (e.g., contrast ratios) of the preview image corresponding to the photographing device in different light states (mainly, in low light states with different ISO values), sequentially increase the contrast ratio of the LCD screen according to a preset increase value, and compensate the contrast ratio corresponding to the photographing device in the light state until a best preview effect in the light state is trained, and at this time, may determine an adjusted contrast ratio of the LCD screen corresponding to the best preview effect. Then, the contrast value corresponding to the shooting device in the light state and the LCD screen contrast value corresponding to the best preview effect are stored in an associated manner, further, the ISO value corresponding to the light state can be stored simultaneously, and then subsequently, for low-light states with different ISO values, the parameter adjusting module 14 can query the stored contrast value corresponding to the shooting device and/or the stored ISO value to obtain the associated LCD screen contrast value, adjust the terminal LCD screen contrast value according to the associated LCD screen contrast value, and increase the LCD screen contrast value to be not lower than the associated LCD screen contrast value, so as to compensate the contrast corresponding to the shooting device.
Further, the parameter adjusting module 14 is further configured to restore a value of a screen parameter corresponding to the image parameter in the terminal screen parameter to a value before the adjustment when the shooting device is detected to exit.
Further, when it is detected that the shooting device is exited, the parameter adjusting module 14 may perform a parameter restoring operation on the screen parameter, so as to restore the value of the adjusted screen parameter to the value before the adjustment. Specifically, when ISO <1200, that is, the photosensitivity value is lower than the preset photosensitivity threshold, and the current light state is not the low-light state, it may indicate that the shooting device is in the normal state, and at this time, the parameter adjusting module 14 may restore the adjusted parameters of the LCD screen to the original parameter values, and no additional compensation is required to be performed on the image parameters.
In the embodiment of the invention, the terminal can detect whether the current light state is the low light state when the shooting device is started, and acquire the current values of the image parameters of the currently acquired image, such as the contrast or the sharpness, when the current contrast value is detected to be lower than the preset contrast threshold or the current sharpness value is detected to be lower than the preset sharpness threshold, the contrast value or the sharpness value in the terminal screen parameters is correspondingly increased, so that the compensation of the image parameters of the shooting device, such as the contrast or the sharpness, is realized, and the preview effect of the shooting device can be effectively improved in the low light state.
