New description: [New technical field] This creation is about a driving recorder, especially a driving recorder with brightness adjustment. [Prior Art] In recent years, more and more vehicles have installed traffic recorders. With the driving recorder, the driver can quickly grasp the condition of the driving according to the information he has recorded. For example, when a gravel car is hit by an enemy, it can be used to see if there is any vehicle, when it is braking, or whether the vehicle system is functioning properly at the time of the accident to clarify the responsibility. In addition to protecting the injured, the rights of the driver are also guaranteed. Therefore, the driving recorder is really necessary. The image recorded by the general traffic recorder is clearly imaged and displayed on a display unit 900, as shown in Fig. 1A. However, if the driving recorder encounters that the outside brightness is too dark or the insulation paper is high (dark), the brightness of the image received by the lens is too dark, which will easily cause the video image to be too dark to be clearly displayed on the display unit. 900, as shown in FIG. 1B; and if the external brightness is too bright or the insulation paper is low (bright), the brightness of the image received by the lens is too bright, and the video image is too bright to be exposed and cannot be clearly displayed. The display unit 9 is as shown by circle 1C. Even if the lens has the function of automatically adjusting the brightness of the image, the display surface of the driving recorder often causes the above problem due to the inability to match the lens. 3 M423644 The author, because of this, in the spirit of active creation, thinking about a driving recorder with brightness adjustment, through the driver to adjust the brightness of the display, so that the driving recorder will not be because of external brightness or heat insulation. Different paper grades affect the imaging effect, thus ensuring the effectiveness of video imaging. After several research experiments, the author completes the creation. [New content] In the prior art, the driving recorder is susceptible to external brightness or thermal paper. Image quality is added to the driving recorder to increase the brightness adjustment function to provide the driver with the ability to manually adjust the display according to the current situation. Brightness to achieve clear imaging and to ensure the effectiveness of video imaging. In order to achieve the above object, the present invention provides a driving recorder with brightness adjustment, comprising an image input unit, a brightness adjusting unit, a data processing unit, a storage unit and a display unit. The image input unit π is used to receive an image and generate an image signal. The brightness adjustment unit includes a gain value (Gain), a brightness value (Brightness), and a gamma value (r) to provide a data processing unit to adjust the parameters of the image. The data processing unit is coupled to the brightness adjusting unit and the image input unit to receive the image signal, and adjust the brightness of the image according to the gain value, the brightness value and the gamma value, and generate a display signal. The storage unit is coupled to the data processing unit and is used to store the brightness adjusted image. The display unit is coupled to the data processing unit 70 ’ to display the brightness-adjusted image screen or the brightness setting screen during brightness adjustment. M423644 In addition, the vehicle recorder may further include a switch button coupled to the data processing unit to generate a switching signal to the data processing unit, and the data processing unit may determine whether to switch to the brightness adjustment according to the switching signal. The brightness setting screen for image screen or brightness adjustment. Furthermore, the vehicle recorder may further comprise an adjustment button set, and the data processing unit is configured to generate a setting signal to the data processing unit, and the data processing unit can adjust the brightness of the image according to the setting signal. Furthermore, the display unit of the vehicle recorder can be a liquid crystal display panel. Furthermore, the display unit of the vehicle recorder can be a touch panel. Furthermore, the image input unit of the vehicle recorder can be a CCD camera. Furthermore, the image input unit of the vehicle recorder can be a cM〇s camera. In addition, the vehicle recorder can be connected to a vehicle power line to drive the vehicle recorder - [Embodiment] Please refer to FIG. 2, which is a schematic diagram of a driving recorder with brightness adjustment according to a preferred embodiment of the present invention. As shown in FIG. 2, the driving recorder with brightness adjustment includes a display unit 200, a data processing unit 21, a brightness adjusting unit 220, a storage unit 230, an image input unit 24, an adjustment button set 250, and A toggle button 260. Among them, the driving recorder is connected to a vehicle power line 205 for supplying power driven by the driving recorder. 5 M423644 Please also refer to FIG. 3, which is a structural diagram of a driving recorder system with brightness adjustment according to a preferred embodiment of the present invention. The image input unit 240 has a lens for receiving an image through a front windshield of the automobile and generating an image signal Im. The brightness adjustment unit 220 includes a gain value (Gain), a brightness value (Brightness), and a gamma value (r) to provide the data processing unit 210 to adjust the parameters of the image. The data processing unit 210 is coupled to the brightness adjusting unit 220 and the image input unit 240 to receive the image signal Im, and adjust the brightness of the image according to the gain value, the brightness value and the gamma value to generate a display signal Sh. The storage unit 230 is coupled to the data processing unit 210 for storing the brightness-adjusted image. The display unit 200 is coupled to the data processing unit 210 to display a brightness-adjusted image screen or a brightness setting screen during brightness adjustment. In the embodiment, the display unit 200 is a liquid crystal display panel, and the image input unit 240 is a CCD camera. The switch button 260 is coupled to the data processing unit 210 to generate a switching signal Ch to the data processing unit 210, and the data processing unit can determine whether to switch to the brightness-adjusted image frame or the brightness adjustment according to the switching signal Ch. Brightness setting screen. The adjustment button group 250 is coupled to the data processing unit 210 to generate a setting signal Ss to the data processing unit 210, and the data processing unit 210 adjusts the brightness of the image according to the setting signal Ss. In this embodiment, the brightness is divided into six levels of different brightness to match the brightness adjustment of the outer boundary. Please refer to FIG. 4A to FIG. 4C at the same time, the driver is driving the car that sticks the glass before the darker heat insulation paper, and sets up a row of vehicle recorders behind the front glass. When the image input unit 240 receives the image of the darker light. At the same time, the image picture displayed by the M423644 display unit 200 will be too dark to be seen clearly, as shown in FIG. 4A. At this time, the driver can switch the video screen to the brightness setting screen by using the switch button 260. Then, the driver manually adjusts the brightness level by adjusting the button group 250 at the brightness adjustment to improve the problem that the external brightness is too dark. The driver can switch to the preview screen to see if the brightness-adjusted image is appropriate. If yes, switch back to the image screen to continue recording the driving situation. At this time, the image recorded by the driving recorder will not be too dark and unrecognizable. On the other hand, when the image input unit 240 receives the image of the brighter line, the image displayed by the display unit 200 will be too bright. At this time, the driver can also adjust the brightness of the image through the above steps to obtain a clearer image. Therefore, it can be seen from the above that the driving recorder of the present invention provides the driver with the ability to manually adjust the brightness of different levels according to different external brightness and insulation paper level to achieve clear imaging, so that the driving recorder achieves the best record quality.
