Description
本發明是關於一種可以點擊放大取像之行車錄影方法與裝置,尤指一種配置有觸控螢幕,且可在錄影過程中藉由碰觸該觸控螢幕上之某一點即可拍下該點的放大照片並擷取一張放大後的靜態圖像的行車紀錄器及其方法。The invention relates to a driving method and device for clicking and zooming in, especially a touch screen, which can be photographed by touching a certain point on the touch screen during recording. A magnified photo and a driving recorder for magnifying the still image and its method.
為了行車安全或是在事故發生時可提供影音紀錄來作為判斷事故責任歸屬之舉證,有越來越多的使用者在其車輛上裝設車用錄影設備例如行車紀錄器等。由於此類的行車紀錄器常需進行數小時以上的長時間持續錄影、且同時又需避免在裝設後會遮蔽到車輛駕駛人的行車視線,所以,一般的行車紀錄器通常體積很小,頂多只配備2英吋左右的顯示螢幕,且大多只具有錄影功能、或是在沒有進行錄影操作的情況下當作數位照相機來拍攝靜態圖像的簡單功能。In order to ensure the safety of driving or to provide audio and video records in the event of an accident, as evidence of the attribution of the accident, more and more users are installing vehicle video equipment such as driving recorders on their vehicles. Since such driving recorders often require long-term continuous recording for several hours or more, and at the same time, it is necessary to avoid the visibility of the driver of the vehicle after installation, the general driving recorder is usually small in size. At most, it only has a display screen of about 2 inches, and most of them only have a video function, or a simple function of taking a still image as a digital camera without performing a video recording operation.
然而,在行車事故發生之當下,需加以錄影或拍攝存證的物體不見得距離很近,而若距離太遠時則很可能無法攝得清晰影像、或是雖有攝得影像可是最重要的關鍵資料(例如肇事車輛的車牌號碼)卻字體太小無法辨識。此外,事故之發生通常來得突然,使用者幾乎都沒有足夠的時間來把行車紀錄器原正在進行中的錄影功能暫停並切換成拍攝靜態圖像的模式後再來拍攝靜態圖像,且更遑論要即時進行將靜態圖像放大縮小的光學或數位變焦操作了。更何況,一旦切換到拍攝靜態圖像的功能後,目前習知的行車紀錄器都需因此暫停持續錄影的功能,無法在持續錄影的過程中進行靜態圖像的拍攝或是拍攝放大後之靜態圖像的功能,其舉證功能顯然不足,而有待進一步改良。However, in the event of a traffic accident, objects that need to be videotaped or photographed are not close enough, and if the distance is too far, it is likely that a clear image may not be captured, or although the image is taken, the most important Key information (such as the license plate number of the vehicle) is too small to be recognized. In addition, the accident usually occurs suddenly, and the user almost does not have enough time to pause the recording function of the driving recorder and switch to the mode of shooting the still image, and then take a still image, and let alone An optical or digital zoom operation that zooms in and out of a still image is performed immediately. What's more, once you switch to the function of shooting still images, the current driving recorder needs to pause the continuous recording function, and it is impossible to take still images during continuous recording or static after shooting. The function of the image, its proof function is obviously insufficient, and needs further improvement.

The operation of storing the motion image in the memory unit 27 in the electronic file under the preset condition means that the captured motion image is recorded for each preset period (for example, every 2 minutes). After 3 minutes, 5 minutes or longer, the motion picture captured during the preset period (which can also be integrated with the digital audio signal of the period) is processed into a dynamic image electronic file and stored in the memory. In the unit 27; and when the storage capacity of the memory unit 27 is insufficient to accommodate the dynamic image electronic file, the control unit 25 will record the earliest of the plurality of dynamic image electronic files previously stored in the memory unit 27 (the earliest recording time) After the one or several motion picture electronic files are deleted to increase the capacity, the currently recorded motion picture electronic file is stored in the memory unit 27. Thus, the inventive driving video device 2 can continue to record for a long time without worrying about the problem of insufficient capacity of the memory unit 27. In addition, the driving video recording device 2 of the present invention has another unique design, that is, the enlarged static image electronic file captured by touching the touch screen 23, if found in the process of being stored in the memory unit 27. When the capacity is insufficient, the control unit 25 of the driving video recording device 2 of the present invention also deletes the dynamic image electronic file of the earliest (the earliest recording time) among the plurality of moving image electronic files originally stored in the memory unit 27, Instead of deleting the static image of the earliest shot. In this way, there is no need to worry that the important still image electronic files that are captured may be deleted because they continue to use the video recording function of the driving video device 2 or after taking multiple photos.
