Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing a main configuration of a real-time adaptive camera shooting mode setting control apparatus according to the present invention.

Referring to the drawings, a real-time adaptive camera shooting mode setting control apparatus according to the present invention includes an illumination sensing unit 100, a shooting mode setting unit 200, an infrared LED operating unit 300, and a sensing value determining unit 400 .

The real-time adaptive camera shooting mode setting control device according to the present invention includes at least one infrared LED 10 to illuminate a subject of a camera lens around a camera lens. As shown in the figure, a plurality of infrared LEDs 10 are arranged in an arc shape around the camera lens, and the infrared LED 10 is turned on and off according to the camera daylight shooting mode to output infrared light.

The illuminance sensing unit 100 is installed on one side of the camera lens and detects illuminance of ambient light received by the camera lens. In the drawing, the illuminance sensing unit 100 allows a single illuminance sensor to be installed on a surface where the infrared LED 10 near the camera lens is installed.

The photographing mode setting unit 200 receives the illuminance sensing value detected by the illuminance sensing unit 100 and compares the transmitted illuminance sensing value with the predetermined nighttime mode conversion illuminance threshold to switch and maintain the day or night photographing mode .

Wherein the day / night mode conversion illumination threshold value is configured to include a daytime entering illumination threshold value, a night entering roughness threshold value and a daytime entering maximum illumination threshold value.

The light intensity threshold value is determined to be a constant value according to the number and specifications of the infrared LEDs 10 mounted on the periphery of the camera lens, and the illuminance threshold value is larger than the internal reflection value by the infrared LED 10. If the roughness sensing value is higher than the weekly entry roughness threshold and is higher than the weekly entry roughness threshold by comparing the roughness sensing value transmitted from the photographing mode setting unit 200 with the photographing mode being the night mode, The controller 200 determines that the camera photographing mode has entered the daytime mode and continues the nighttime mode if the transmitted illumination intensity value is smaller than the weekly entry roughness threshold value.

The night entry roughness threshold value is lower than the weekly entry roughness threshold value, and it is generally preferable to set the roughness value of about 5 lux to the threshold value. When the photographing mode setting unit 200 determines that the illumination sensing value is lower than the night entry illumination threshold by comparing the illumination sensing value transmitted from the photographing mode setting unit 200 with the night entry illumination threshold, It is determined that the camera shooting mode has entered the night mode, and the night mode is maintained if the transmitted illumination intensity value is smaller than the threshold value of the night approaching illumination.

The inter-day maximum illumination threshold value is a maximum illumination value that the infrared LED 10 mounted on the periphery of the camera lens can emit. When the illumination sensing value transmitted from the shooting mode setting unit 200 exceeds the inter-day maximum illumination intensity threshold The sensing value determination unit 400 determines that the current state is switched to the daytime mode without determining whether the sensing value is valid.

The infrared LED operation unit 300 controls the blinking operation of the infrared LED 10 when the photographing mode is switched by the day / night mode determined by the photographing mode setting unit 200. [ That is, when it is determined that the shooting mode determined by the shooting mode setting unit 200 enters the night mode in the daytime mode, the infrared LED operation unit 300 generates a control command so that the infrared LED 10 is turned on, The infrared LED operation unit 300 generates a control command so that the infrared LED 10 is turned off when it is determined that the shooting mode determined by the shooting mode setting unit 200 enters the daytime mode in the mode state.

The sensing value determination unit 400 determines whether or not the light emitted from the infrared LED 10 influences the illumination sensing value detected by the illumination sensing unit 100 under the control of the infrared LED operation unit 300 do. This is because the illuminance sensing unit 100 generates light intensity by sensing light of visible wavelength range visible to the eye, but causes the light generated from the infrared LED 10 to pass through the visible light wavelength band The illuminance sensing value can be increased by turning on the infrared LED 10 at the time of entering the night mode. Accordingly, in the present invention, the sensing value determiner 400 is separately provided to determine whether the illuminance sensing value compared at the time of switching to the photograph mode is valid.

That is, when it is recognized that the camera photographing mode is switched, the illuminance sensing value detected in the blinking state of the L infrared LED 10 according to the switched photographing mode exceeds the illumination threshold value and the photographing mode is again switched from night to day mode When the infrared LED 10 is turned on, the infrared LED 10 is flickered in a state before switching to the photographing mode, and the roughness sensing value is re-detected to judge whether the roughness sensing value is valid by re-comparing with the roughness threshold value.

Such a photographing mode validity judgment occurs when the night mode is switched, and when the photographing mode is switched from the daytime mode to the nighttime mode, the infrared LED 10 is turned on to influence the roughness sensing value.

More specifically, when the daytime mode is switched to the first night mode, and the illuminance sensing value detected when the infrared LED 10 is turned on is greater than the threshold value of the weekly entering roughness, and the photographing mode is to be switched to the daytime mode again , The sensing value determination unit 400 determines whether the detected illumination sensing value is valid when the infrared LED 10 is on.

To this end, the infrared LED 10 is turned off again according to the night mode switching, and the illumination sensing value is re-detected in a state where the infrared LED 10 is off, and the weekly entering roughness is again compared with the threshold value. As a result of the comparison, if the re-detected roughness sensing value exceeds the threshold value of the weekly entering roughness, the night mode is switched back to the day mode again. If not, the roughness sensing value exceeding the weekly entering roughness threshold value is newly And the nighttime mode is maintained.

When the photographing mode is switched from the night mode to the week mode, the photographing mode setting unit 200 sets the photographing mode setting unit 200 to set the weekly entering roughness threshold value to the predetermined roughness threshold value from the new roughness threshold value updated by the sensing value determining unit 400 Reset to the threshold value.

Hereinafter, a real-time adaptive camera shooting mode setting control method according to the present invention will be described in detail.

FIG. 3 is a view showing an example of a photographing mode determination method according to a day / night mode conversion illumination threshold value, FIG. 4 is a diagram illustrating an example of a photographing mode determining method according to an embodiment of the present invention, FIG. 10 is a flowchart showing a detailed procedure for judging the switching validity. FIG.

The method for controlling the setting of the real-time adaptive camera shooting mode according to the present invention may include an illuminance detection step S210, a shooting mode determination step S220, an infrared LED operation step S230, ).

In the illuminance detection step S210, the illuminance of the ambient light received by the camera lens is detected through the illuminance sensor installed on one side of the camera lens to generate the illuminance sensing value.

In the photographing mode determination step S220, the detected illuminance sensing value is compared with a predetermined nighttime mode conversion illumination threshold value to determine whether to switch to the day or night photography mode or to maintain the current state.

3, the day / night mode conversion illumination threshold value includes a daytime entering roughness threshold, a night entering roughness threshold, and a weekly entering maximum roughness threshold, and the roughness sensing value is a weekly entering roughness threshold (Tday), it is determined that the mode is entered into the daytime mode. If the illumination sensing value is less than the night entrance roughness threshold value (Tnight), it is determined that the mode enters the nighttime mode. If the illumination sensing value exceeds the weekly entering maximum illumination threshold value (Tdmax), it is recognized that the photographer enters the unconditioned day mode without going through the photographing mode conversion validity determination step. If the illuminance sensing value does not deviate from the threshold value in the conventional photographing mode, the conventional mode is maintained.

In the infrared LED driving step S230, when the photographing mode is to be switched in the photographing mode determining step S220, the infrared LED is blinked based on the photographing mode. More specifically, the infrared LED is turned on when entering the night mode from the weekly mode, and the infrared LED is turned off when entering the day mode from the night mode.

In the photographing mode switching validity determination step S240, in order to determine whether the light generated by the blinking of the infrared LED affects the illumination sensing value, the infrared LED is set to the blinking state before the photographing mode changeover, Value and the day / night mode conversion illumination threshold value to judge whether the photographing mode switching is effective. As a result, when the photographing mode is changed from the night mode to the daytime mode, . That is, when entering the night mode, the infrared LED is turned on, and the illuminance sensor mistakenly recognizes the infrared light, and the detected illuminance sensing value exceeds the weekly entering roughness threshold value Tday.

According to the present invention, it is judged whether or not the photographing mode change is effective according to such a defect.

Referring to FIGS. 3 and 4, when the photographing mode is changed from the day mode to the first night mode (S410), the infrared LED is turned on (S420). That is, the illuminance value is sensed as the value of the point (a) in FIG. 3, and the night mode is entered.

Then, in a state in which the infrared LED is lit, the illumination sensing value is continuously detected to compare the illumination sensing value with the daytime entering illumination threshold (S430).

If the roughness sensing value does not exceed the weekly entry roughness threshold, the roughness sensing value is detected again and the weekly roughness threshold is repeatedly compared with the threshold value.

If the illuminance sensing value exceeds the threshold value of the inter-day entering roughness, the infrared ray LED is turned off first without switching the photographing mode to the daytime mode (S440). That is, in FIG. 3, it is considered whether the roughness threshold value Tday1 corresponds to the point (b) to change to the daytime mode.

Then, in a state where the infrared LED is off, the illumination sensing value is re-detected (S450). Then, the re-detected roughness sensing value and the inter-day entering roughness threshold value are compared again (S460).

As a result of the re-comparison, if it is determined that the re-detected roughness sensing value exceeds the weekly entry roughness threshold, the photographing mode is changed from the night mode to the day mode again to determine that the previously detected roughness sensing value is valid (S470) .

However, if it is determined that the re-detected roughness sensing value does not exceed the weekly entering roughness threshold value, that is, if the roughness sensing value of the point (c) It is recognized that the sensing value Tday1 is influenced by the infrared LED and the roughness sensing value Tday1 detected above the threshold value of the weekly entering roughness is updated to the new weekly entering roughness threshold in step S480.

Then, the later-detected roughness sensing value is compared with the new weekly entering roughness threshold value to check the photographing mode. When the mode is switched by re-entering into the day mode and comparing with the future roughness sensing value and the new weekly entering roughness threshold, the weekly entering roughness threshold is updated from the new roughness threshold value Tday1 to the preset roughness threshold value Tday ). This causes resetting of the initial threshold value to the possibility that the updated illumination threshold value may be repeatedly higher.

If the illumination sensing value exceeds the weekly entry maximum illumination threshold value Tdmax in the photographing mode determination step S220, it is determined that the photographing mode has been switched to the daytime mode without going through the photographing mode change validity determination step S240 .

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications and variations without departing from the spirit and scope of the invention. Accordingly, the scope of the appended claims should include all such modifications and changes as fall within the scope of the present invention.
