Abstract

Photographers often decide the number of subjects they want in their frame before taking a photograph. We suggest a method of specifying a minimum and maximum threshold value for arbitrary subjects.

Method to specify number of features desired in photograph

Currently cameras provide face detection software for auto focusing and auto capturing when the subjects smile.

    Current implementations do not allow the user to specify a minimum or maximum limit to the number of features in an image.

Primary embodiment:

    
A user wants to take a photo of themselves against a window using a mobile phone but does not have a front facing camera so they can not look at the screen. They enable the maximum limit to 1 and take the photo. If somebody outside looks in the window while they are taking the photo the phone can raise an alert sound and waits until the number of faces is within the range

Another embodiment:

    
A user wants to take a family photo at a wedding of 50 people, but some of the subjects look away to communicate with people outside the photo while the photographer depresses the button. By setting the minimum smile limit to 45 and the maximum smile limit to 50, the photographer can depress the button and the image

will be captured when the number of smiles is within the range.

    This achieves a method to specify the minimum number of features desired in a photograph.

    This achieves a method to specify the maximum number of features desired in a photograph.
