Abstract

A driving recorder capable of assisting in correcting a shooting posture and a correction method of the same are provided. The driving recorder includes: an image capturing unit, a gravity sensing unit, a storage unit and a processing unit. The gravity sensing unit senses an orientation of the driving recorder and generates angle information; the storage unit stores shooting angle logic tables to correspond to a variety of orientations of the driving recorder; and the processing unit selects a corresponding shooting angle logic table from the storage unit according to the angle information, and generates an actuation signal, so as to adjust a shooting angle of the image capturing unit.

Claims

1. A driving recorder capable of assisting in correcting a shooting posture, comprising:

an image capturing unit;

a gravity sensing unit, for sensing an orientation of the driving recorder and generating angle information;

a storage unit, for storing shooting angle logic tables to correspond to a variety of orientations of the driving recorder; and

a processing unit, for selecting a corresponding shooting angle logic table from the storage unit according to the angle information, and generating an actuation signal, so as to adjust a shooting angle of the image capturing unit.

2. The driving recorder capable of assisting in correcting a shooting posture according to claim 1, wherein the image capturing unit further comprises a photosensitive module.

3. The driving recorder capable of assisting in correcting a shooting posture according to claim 2, wherein the photosensitive module adjusts a direction according to data obtained by the gravity sensing unit after measurement.

4. The driving recorder capable of assisting in correcting a shooting posture according to claim 1, wherein the image capturing unit and the gravity sensing unit have a coordinate correspondence therebetween.

5. The driving recorder capable of assisting in correcting a shooting posture according to claim 1, wherein the shooting angle of the image capturing unit is parallel with a road surface.

6. A correction method of a driving recorder capable of assisting in correcting a shooting posture, applicable to a driving recorder, wherein the driving recorder at least comprises a storage unit for storing shooting angle logic tables to correspond to a variety of orientations of the driving recorder, the correction method comprising:

sensing, by a gravity sensing unit, an orientation of the driving recorder and generating angle information;

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; and

adjusting a shooting angle of an image capturing unit according to the actuation signal.

7. The correction method of a driving recorder capable of assisting in correcting a shooting posture according to claim 6, wherein the step of adjusting a shooting angle of an image capturing unit according to the actuation signal further comprises;

adjusting a shooting angle of a photosensitive module of the image capturing unit according to the actuation signal.

8. The correction method of a driving recorder capable of assisting in correcting a shooting posture according to claim 7, further comprising:

adjusting a direction of the photosensitive module according to data obtained by the gravity sensing unit after measurement.

9. The correction method of a driving recorder capable of assisting in correcting a shooting posture according to claim 6, further comprising:

comparing the image capturing unit with the gravity sensing unit to obtain a coordinate correspondence between the image capturing unit and the gravity sensing unit.
