Prompting terminal and prompting method for forward and backward moving of depth of field during panorama shooting

Abstract

The invention discloses a prompting terminal for forward and backward moving of a depth of field during panorama shooting. The prompting terminal comprises: an establishing module, which forms a vertical trajectory and a vertical indication point on a screen in a panorama shooting mode; a first obtaining module, which obtains, at an n moment, a first depth of field corresponding to pixels of a first preset fixed zone within an n image, wherein the first depth of field represents the vertical indication point and is located in the middle of the vertical trajectory; a second obtaining module, which obtains a second depth of field corresponding to pixels of a second preset fixed zone within an (n+1) image if the pixels of the second preset fixed zone within an (n+1) image are the same with the pixels of the first preset fixed zone within the n image at an (n+1) moment; and a processing module, which adjusts the position of the vertical indication point on the vertical trajectory on the basis of the first depth of field and the second depth of field. In this way, a problem of layering during shooting of a panorama photograph is avoided. The invention also discloses a prompting method for forward and backward moving of a depth of field during panorama shooting.

Description

technical field [0001] The invention relates to the field of terminal image shooting and processing, in particular to a terminal and method for prompting the depth of field to move back and forth during panoramic shooting. Background technique [0002] With the advancement of science and technology, the camera function of mobile phones is becoming more and more powerful. Users can take panoramic photos without professional camera equipment and only use their mobile phones; The arrow moves along the horizontal line to remind the user whether the current shooting is taking pictures on the same straight line, so as to prevent the fault phenomenon of the picture when there is an up and down shift; The problem is that there is still a problem of front and back stretching, which leads to the problem of layering in the photographed photos. However, the existing technology only solves the problem of preventing the fault phenomenon of the picture when there is an up and down shift, b...

[0002] With the advancement of science and technology, the camera function of mobile phones is becoming more and more powerful. Users can take panoramic photos without professional camera equipment and only use their mobile phones; The arrow moves along the horizontal line to remind the user whether the current shooting is taking pictures on the same straight line, so as to prevent the fault phenomenon of the picture when there is an up and down shift; The problem is that there is still a problem of front and back stretching, which leads to the problem of layering in the photographed photos. However, the existing technology only solves the problem of preventing the fault phenomenon of the picture when there is an up and down shift, but does not stretch the front and back, resulting in the splitting of the photographed photos. layers to solve
