Executive Summary: this disclosure provides a new function to be introduced in photographic devices, to improve the quality of resultant pictures. When people take pictures, the position of object(s) in a viewfinder can always be defined subjectively. While it's OK for professional people, but it can be very difficult to the ordinaries to define a good position. Currently, there are some solutions that can solve this problem a bit, such as putting golden ratio grad inside of the viewfinder to let the user positions the object according to golden ratio, that may be helpful, but it still needs to be judged subjectively, and to normal people, they may still don't know how to apply it. Therefore, if there is some function that can detect a good position objectively according to certain rules, and let the user know it's the time to press the shutter, it will be no problem for the ordinaries to make good photos.

Optimal Position Detection for Making Pictures

When making a picture, the shooting object(s) should be defined first, then, inside of the viewfinder (or somewhere outside of the viewfinder), there can be some arrows to indicate the user where to move the camera till find optimal position. The rule to define a good position can be according to golden ratio which is known as an aesthetically pleasing ratio, because it was used by many middle age artist to draw pictures (of course, the rule can be others if that's more suitable to define a good position). Once the best position is detected, the camera may use a phonic feedback or keep flashing somewhere to indicate the user it's the time to press shutter. If the user doesn't position correctly and pressed the shutter, the camera can automatically cut the picture's edges to position the person into a right position.


1. instead of subjective decision of a good position, we can judge optimal position objectively according to a certain rule, such as golden ratio.

2. It can improve user experience:

a. As it has some arrow indication to tell user how to position the camera rather than let user directly use golden ratio grad, or even nothing.

b. After detecting the good position, a phonic feedback or keep flashing signal can make the user feel confident to press shutter.

Declare Points:

Define optimal position objectively and automatically indicate the user how to move the camera.

Once the target object being positioned in a optimal position, the camera should give a phonic or flashing feedback to notify the user to press shutter.

If the user selects using optimal position to take pictures, even the user position the person into a wrong place, the system is still able to cut the picture's edges to make the person locates in a better position.

The invention should follow below steps when a user start to take a picture

a. the user should define shooting objects(s) in the viewfinder, it can be any object, for instance, a person's head. The user can simply press on the

object to select, or the camera can have some automatic detection to define the targets.

b. Base on selected object(s), calculate optimal position according to a certain rule. The rules can be various base on modern photographic knowledge, for example, the golden ratio.

c. After calculation, the device should indicate the user how to position the viewfinder, it may use some arrows to tell the user where to move, even zoom in / out.

d. then the user should moved the camera to a optimal position according to the indication, if the position hasn't been found, the processing should keep going back to step b

e. if the optimal position is detected as the user moving the camera, the device shou...
