CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Taiwan Patent Application No. 103113028, filed on Apr. 9, 2014, which is hereby incorporated by reference for all purposes as if fully set forth herein.

BACKGROUND

1. Technical Field

The present disclosure relates to a driving recorder capable of assisting in correcting a shooting posture and a correction method of the same, and more particularly to a driving recorder capable of assisting in correcting a shooting posture and capable of adjusting a shooting angle by using a gravity sensor, and a correction method of the same.

2. Related Art

It is increasingly common to install a driving recorder in a vehicle in recent years, and the driving recorder is an audio and video recording system which is used for recording road conditions during a travel period of a vehicle. By means of the driving recorder, once a traffic accident occurs, images shot by the driving recorder even in combination with recorded contents can be used to assist in determining causes of the accident and attribution of responsibility.

A conventional driving recorder substantially includes a lens, an image processor, a memory device and other elements or devices that are disposed in a casing, where the lens is used for shooting images; the image processor is used for processing conversion between analog signals and digital signals; and the memory device is an electronic device for storing the shot images and recording sound.

Based on considerations of a wide shooting angle, the convenience in operation, and other factors, an external driving recorder is generally disposed on a driving console. However, the disposing the driving recorder on the driving console not only affects the sight of the driver to cause traffic safety issues, but also affects the appearance; even, vibrations occurring in driving may cause shifts of photographic lens, and the lens angle needs to be adjusted frequently. Moreover, during on-road driving, the shooting angle of the photographic lens of the driving recorder may be changed due to road conditions, and the photographic lens cannot capture images at expected orientations, so the angle of the photographic lens needs to be adjusted whenever the driving recorder shakes. On the other hand, if the driving recorder is formed of a photographic lens and other components that are separated from the photographic lens, a transmission line for connecting the lens and the other components also affects the appearance as the line is exposed.

In FIG. 1, a driving recorder capable of assisting in correcting a shooting posture includes an image capturing unit 110, a gravity sensing unit 120, a storage unit 130 and a processing unit 140. The image capturing unit 110 further includes a photosensitive module 150.

The gravity sensing unit 120 and the image capturing unit 110 have a coordinate correspondence therebetween (as shown in FIG. 2), so as to sense an orientation of the driving recorder and generate angle information. The storage unit 130 stores shooting angle logic tables to correspond to a variety of orientations of the driving recorder.

During travelling of a vehicle 300, the shooting angle of the image capturing unit 110 needs to be parallel with the road surface (as shown in FIG. 3) and maintain in this state. When the angle between the image capturing unit 110 and the road surface deflects, the processing unit 140 selects a corresponding shooting angle logic table from the storage unit 130 according to the angle information and generates an actuation signal, so as to adjust the shooting angle of the image capturing unit 110 and a direction of the photosensitive module 150 (as shown in FIG. 4).

Referring to FIG. 5 and FIG. 6 together, FIG. 5 and FIG. 6 are flowcharts illustrating a shooting posture correction method of a driving recorder. The correction method of a driving recorder capable of assisting in correcting a shooting posture is applicable to a driving recorder, where the driving recorder at least includes a storage unit for storing shooting angle logic tables to correspond to a variety of orientations of the driving recorder. The correction method includes the following steps: first, comparing an image capturing unit with a gravity sensing unit, to obtain a coordinate correspondence between the image capturing unit and the gravity sensing unit (Step S501); next, sensing, by the gravity sensing unit, an orientation of the driving recorder and generating angle information (Step S510), and selecting, by a processing unit, a corresponding shooting angle logic table from the storage unit according to the angle information and generating an actuation signal (Step S520); and finally, according to the actuation signal, adjusting a shooting angle of the image capturing unit (Step S530) and adjusting a shooting angle of a photosensitive module of the image capturing unit (Step S531).
