Abstract
An image capturing device with high image sensing coverage rate is applied by a related image capturing method. The image capturing device includes a base, an image sensing unit and an optical lens component. The image sensing unit is disposed on a lateral surface of the base, and has a sensing region. The optical lens component is overlapped with the image sensing unit, and has an imagery circle. A central optical axle of the imagery circle does not align with a central point of the sensing region; wherein the image capturing device captures an image via the optical lens component and the imaging sensing unit.

An image capturing device with high image sensing coverage rate, the image capturing device comprising:
- a base;
- an image sensing unit disposed on a lateral surface of the base and having a sensing region;
- and
- an optical lens component overlapped with the image sensing unit and having an imagery circle, a central optical axle of the imagery circle not aligning with a central point of the sensing region;
- wherein the image capturing device captures an image via the optical lens component and the imaging sensing unit;
- wherein the image capturing device further comprises another image sensing unit and another optical lens component disposed on another lateral surface of the base in an overlapped manner, and a central optical axle of an imagery circle of the another optical lens component does not align with a central point of a sensing region of the another image sensing unit.
An image capturing method with high image sensing coverage rate applied to an image capturing device, the image capturing device having a base, an image sensing unit and an optical lens component overlapped with each other, the image sensing unit and the optical lens component being disposed on the same lateral surface of the base, the image capturing method comprising:
- determining an orientation of a fixing portion of the base;
- shifting at least one of the image sensing unit and the optical lens component to move a central optical axle of an imagery circle of the optical lens component to a position located between a central point of a sensing region of the image sensing unit and the fixing portion, so as to make the central point not align with the central optical axle;
- and
- driving the image capturing device to acquire an image via the image sensing unit and the optical lens component.
