Description

M396548 五、新型說明：【新型所屬之技術領域】本創作係關於一種監視攝影機，尤指一種整合有多種感測作業模式’可視監視地點選擇m式以降低誤動作的監視攝影機。M396548 V. New description: [New technical field] This creation is about a surveillance camera, especially a surveillance camera that incorporates multiple sensing operation modes, where the visual surveillance location is selected to reduce misoperation.

【先前技術】監視攝影機於實際運用時係攝影的動作’藉著偵測環境照度 24小時不停地進行監視大小來判斷是否切換晝面為办色或黑白，因此在白天或室内光線充^下會自動使用彩色顯示’在夜晚'室内昏暗或是照度不足時，則畫面自動轉為黑白顯示；@目前監視攝影機在判斷光線時仍難免會發生誤判’導致彩色/黑白晝面之不當轉換。目别市面上監視攝影機之光線判斷方式包含有兩類，[Prior Art] The camera monitors the action of photography in actual use. By detecting the ambient illumination for 24 hours, the size of the monitor is continuously monitored to determine whether to switch the face to color or black and white, so the daytime or indoor light is charged. Will automatically use the color display 'in the night' indoors dim or lack of illumination, the picture will automatically turn black and white display; @current surveillance camera will still inevitably misjudge when judging the light', resulting in improper conversion of color / black and white. There are two types of light judgment methods for surveillance cameras on the market.

’、項疋採用光感測器（Photo transistor, PT)來偵測周圍衣兄光線，當其判斷周圍環境光線充足時係以彩色模式進行視’反之於光線不足時即開啟紅外線（IR)功能進行仗視黑白監控。但其缺點在於當監視攝影機係裝設在一光線相對較暗的環境時，而其鏡頭卻朝向一相對明亮的場合進订拍攝作業’理論上應是以彩色模式監示該明亮處以取 -g- &面’但光感測器將自動判定周圍環境光線不足而 I用黑白^式，顯然無法獲得較適當的監控品質。另類監視攝影機則是依據CCD影像感測元件所拍攝到的查> A由免度而決定應執行彩色或黑白模式。這類型的攝’以機不以周圍環境光線為判斷依據，而是直接以所拍攝 3', Item 疋 uses a photo sensor (PT) to detect the light of the surrounding brothers, when it judges that the ambient light is sufficient, it is viewed in color mode. Otherwise, the infrared (IR) function is turned on when the light is insufficient. Perform black and white surveillance. However, the disadvantage is that when the surveillance camera is installed in a relatively dark environment, the lens is directed to a relatively bright occasion. In theory, the bright position should be monitored in a color mode to take -g - & face' but the light sensor will automatically determine that the ambient light is insufficient and I use black and white ^, obviously can not get more appropriate monitoring quality. The alternative surveillance camera is based on the detection of the CCD image sensing component. A is determined by the degree of freedom to perform color or black and white mode. This type of camera is based on the fact that the machine does not rely on the ambient light, but directly shoots it.

Claims

M396548 white image surveillance video; When the microcontroller performs the composite sensing mode, it switches to refer to the CCD image sensor and the light sensor to determine whether color or black and white image monitoring video should be enabled. 3. The surveillance camera that can set day and night sensitization conditions as described in item 2 of the patent application is set to the rear side of one of the camera bodies. 4. If the surveillance camera that can set the day and night sensitivity conditions as described in item 2 of the patent application is selected, an on-screen menu (OSD) is displayed to complete the setting operation when the sensor mode is selected.
