Abstract

A guiding method for photographing a panorama image is described. A motion vector between a current position of an alignment image in a real-time image and a joint position of the alignment image in the real-time image, and a direction indicator relative to the motion vector is displayed, such that when the digital camera device displays the real-time image, the digital camera device may display the direction indicator to guide a photographing position of a next image for a user, thereby simplifying the photographing of a panorama image and greatly decreasing an incidence that the user fails to photographing a panorama image.

Claims

1. A guiding method for photographing a panorama image, applied in a digital camera device, wherein the digital camera device has a camera module and a display screen, the guiding method comprising:

acquiring a first image by photographing scenery in front of the digital camera device with the camera module;

storing the first image;

acquiring a real-time image by capturing scenery in front of the digital camera device with the camera module after acquiring the first image;

calculating a motion vector between a current position of an alignment image in the real-time image and a joint position of the alignment image in the real-time image, wherein the alignment image is an image block in the real-time image with the same scenery as the first image, the joint position is a position where a second image to be photographed joins with the first image, and scenery of the second image is the same as the scenery of the real-time image at the time of photographing to acquire the second image;

displaying the real-time image on the display screen and displaying a direction indicator relative to the motion vector, wherein a direction of the direction indicator corresponds to a direction of the motion vector, and a length of the direction indicator corresponds to a value of the motion vector; and

detecting the real-time image continuously, wherein when it is detected that the real-time image is changed, the process returns to the step of acquiring the real-time image, so as to perform the steps of acquiring the real-time image, calculating the motion vector, and displaying the real-time image and the direction indicator again, such that the length of the direction indicator changes with the real-time image.

2. The guiding method for photographing a panorama image according to claim 1, further comprising:

outputting a sound suggestion corresponding to the motion vector when displaying the real-time image and the direction indicator.

3. The guiding method for photographing a panorama image according to claim 1, further comprising:

generating at least a vibration corresponding to the motion vector when displaying the real-time image and the direction indicator.

4. The guiding method for photographing a panorama image according to claim 1, wherein the direction indicator is displayed in a flickering manner when displaying the real-time image and the direction indicator.

5. The guiding method for photographing a panorama image according to claim 1, further comprising:

acquiring the second image by photographing scenery in front of the digital camera device with the camera module according to the motion vector; and

joining the first image and the second image, thereby obtaining a panorama image.

6. A guiding method for photographing a panorama image, applied in a digital camera device, wherein the digital camera device has a camera module and a display screen, comprising:

acquiring a first image by photographing scenery in front of the digital camera device with the camera module;

storing the photographed first image;

acquiring a real-time image by capturing scenery in front of the digital camera device with the camera module after acquiring the first image;

calculating a motion vector between a current position of an alignment image in the real-time image and a joint position of the alignment image in the real-time image, wherein the alignment image is an image block in the real-time image with the same scenery as the first image, the joint position is a position where a second image to be photographed joins with the first image, and scenery of the second image is the same as the scenery of the real-time image at the time of photographing to acquire the second image;

calculating a plurality of vector components of the motion vector in a plurality of different directions;

displaying the real-time image on the display screen and displaying a plurality of direction indicators relative to the plurality of calculated vector components, wherein each of the direction indicators corresponds to one of the plurality of vector components, a direction of the direction indicator correspond to a direction of the corresponding vector component, and a length of the direction indicator corresponds to a value of the corresponding vector component; and

detecting the real-time image continuously, wherein when it is detected that the real-time image is changed, the process returns to the step of acquiring the real-time image, so as to perform the steps of acquiring the real-time image, calculating the motion vector and the plurality of vector components, and displaying the real-time image and the direction indicators subsequently, such that the length of the direction indicator changes with the real-time image.

7. The guiding method for photographing a panorama image according to claim 6, further comprising:

outputting a sound suggestion corresponding to the motion vector when displaying the real-time image and the plurality of direction indicators.

8. The guiding method for photographing a panorama image according to claim 6, further comprising:

generating at least a vibration corresponding to the motion vector when displaying the real-time image and the plurality of direction indicators.

9. The guiding method for photographing a panorama image according to claim 6, wherein the plurality of direction indicators is displayed in a flickering manner when displaying the real-time image and the plurality of direction indicators.

10. The guiding method for photographing a panorama image according to claim 6, further comprising:

acquiring the second image by photographing the scenery in front of the digital camera device with the camera module according to the motion vector; and

joining the first image and the second image thereby obtaining a panorama image.
