Embodiment Construction
[0019] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.
[0020] refer to figure 1 , an embodiment of the driving recorder 1 of the present invention is suitable for being installed in a vehicle (not shown), and includes: a light source sensing module 11 , a video recording module 12 , and a processing module 13 .
[0021] The light source sensing module 11 is used to detect the illuminance, and the light source sensing module 11 detects the illuminance every unit time to generate a corresponding illuminance value. The video recording module 12 is used for video recording. The processing module 13 is electrically coupled to the light source sensing module 11 and the video recording module 12 to control whether the light source sensing module 11 and the video recording module 12 operate or not.

The invention relates to a parking recording starting method, which is performed by a vehicle driving recorder, wherein the vehicle driving recorder comprises a light source sensing module, a recording module and a processing module electrically coupled to the light source sensing module and the recording module. The parking recording starting method comprises that (A) the processing module controls the recording module to enter a standby mode; (B) the processing module controls the light source sensing module to detect the illuminance every unit time so as to correspondingly generate an illuminance value; and (C) when the processing module determines that the variation of the consecutive two illuminance values exceeds a first preset threshold value, reached, the processing module then determines whether the consecutive change number of the illuminance values is equal to or exceeds a second preset threshold value, and if so, the recording module is started and records.
Description
technical field [0001] The invention relates to a control method and a driving recorder, in particular to a method for starting parking video recording and a driving recorder applying the method. Background technique [0002] Most of the existing driving recorders are equipped with a parking detection and video recording function, which starts the detection function after the vehicle is stopped and turned off, and starts recording when the driving recorder finds that the captured picture has changed. However, the current technology mainly uses the lens of the driving recorder to shoot in a preview mode or in a frame-down mode, and detects whether there is any change in the captured picture to determine whether to start recording. [0003] For example, the current driving recorder lens consumes about 300 milliamps (mA) in preview mode, and the built-in batteries of commercially available driving recorders are generally only a few hundred to nearly a thousand milliampere hours...
