Embodiment 1

[0068] A first list includes correspondence between multiple photo modes and reference lines, the photo modes include: travel photos (that is, the ratio of the length of the face to the length of the viewfinder frame is greater than or equal to 1 / 10 and less than 2 / 3), Close-ups of faces (that is, the ratio of the length of the face to the length of the viewfinder is greater than or equal to 2 / 3), landscapes (that is, the length of the face is greater than or equal to 0 and less than 1 / 10);

[0069] The reference line corresponding to the travel photo is a horizontal golden section line and a vertical golden section line, and the intersection of these two golden section lines is close to the current position of the face;

[0070] The reference line corresponding to the close-up of the face is the intersection point in the center of the viewfinder or no reference line.

[0071] The reference line corresponding to the scenery is the Jiugongge reference line.

[0072] see figur...

Embodiment 2

[0089] A mobile phone camera preview composition assistance method, see Figure 6 ,Proceed as follows:

[0090] Step 31, collecting image information in the current viewfinder frame.

[0091] Step 32. Perform preprocessing on the collected image information, filter out noise points, and extract the target object from the collected image information.

[0092] Step 33, acquiring the area of ​​the target object.

[0093] Step 34: Determine the image type to which the target object belongs, and obtain the designated area corresponding to the image type in a second list, and the second list includes the correspondence between the image type and the designated area.

[0094] Step 35. Adjust the focal length so that the area of ​​the target object is equal to the specified area.

[0095] The target object can be automatically selected by the mobile phone as the object with the highest priority in the current viewfinder frame, and the priority is that the human face is higher than ...

Embodiment 3

[0103] A mobile phone camera preview composition assistance method, see Figure 7 ,Proceed as follows:

[0104] Step 41, collecting image information in the current viewfinder frame and acquiring the area of ​​the current viewfinder frame.

[0105] Step 42 , preprocessing the collected image information, filtering out noise points, and extracting the target object from the collected image information.

[0106] Step 43. Obtain the area of ​​the target object.

[0107] Step 44. Determine the image type to which the target object belongs, and obtain the designated ratio corresponding to the image type in a third list, the third list includes the correspondence between the image type and the designated ratio, and the designated ratio The ratio is the ratio of the specified area of ​​the image type to the area of ​​the viewing frame;

[0108] Step 45, calculating the specified area of ​​the target object, the specified area is equal to the area of ​​the current viewfinder multipli...

Abstract

The invention discloses a shooting preview composition assisting method and device for shooting equipment. The shooting equipment comprises a viewing frame. The shooting preview composition assisting method of the shooting equipment comprises the following steps: image information in the current viewing frame is collected, and the size of the current viewing frame is acquired; a target object is extracted from the image information; the size of the target object is acquired, and a viewing parameter is calculated, wherein the viewing parameter is equal to the ratio of the size of the target object to the size of the current viewing frame; a reference line, corresponding to the viewing parameter, in a first list is searched for and displayed, wherein the first list contains the corresponding relation between the viewing parameter and the reference line, and the reference line is used for prompting the set position of the target object in the viewing frame. By means of the shooting preview composition assisting method and device for the shooting equipment, different reference lines can be displayed according to actual conditions of pictures so that a user can be prompted to take pictures which can better meet the habits of the user or have a higher sense of beauty.

Description

technical field [0001] The invention relates to an auxiliary method and device for photographing and previewing composition of photographing equipment. Background technique [0002] Taking pictures has become an indispensable thing in people's life. From the scenery souvenirs when traveling to selfies and pictures, everyone wants to take beautiful photos. The existing mobile phones basically have the function of taking pictures, and there are often two The camera, the pixels of the camera may also reach the level of professional digital cameras, and there is a tendency to replace digital cameras. However, not everyone is a professional photographer for the grasp of camera technology. Many photos are taken or people are biased to one side. Either the head is too big or too small, and these problems are difficult to detect during the photo taking process due to the small screen of the mobile phone or digital camera. It is easy to find it after importing it into the computer, b...
