Abstract

This disclosure is tring to resolve the common issue that people exhibit improper facial expressions during a photo taking process. Using a facial expression recognition--a known technology--built in user cameras and entails defining all criteria to match improper facial expressions including but not limited to closed eyes, not facing camera, and/or sheltered faces. A process of identifying photograph with improper facial expressions by a set of predefined criteria will be used in this disclosure to extract and anlysis the facial expression pulled from picture through a preview. When an improper facial expression matched or mismatched, the combinations of three options (disable shutter button ,warning the user on digital screen or audible indicator, or automatically take photo after some delay with rechecks for improved expression) would be taken.

It's a common issue that people exhibit improper facial expressions during a photo taking process, as it is difficult for the photographer to assess everyone's expressions when pressing the shutter button. For example, a subject may not be facing the camera, a subject's eyes may be closed, or part of a subject's face is masked by other people. Such bad experience occur for everyone, at some point, particularly when group photographs are taken. Based on maturing technology of facial recognition, the above bad experiences can be greatly relieved by identifying improper facial expressions, and either prompting camera users or taking predefined actions.

This disclosure requires that facial expression recognition--a known technology--be built into the user cameras. The invention then entails defining all criteria to match improper facial expressions including closed eyes, not facing camera, and/or sheltered faces. Meanwhile, actions will be defined for both criteria matching or mismatch. Actions for matching criteria can be any one or combinations of three options: (a) disable shutter button (note that this can be overridden by the user), (b) warning the user on digital screen or audible indicator, (c) automatically take photo after some delay, with rechecks for improved expressions. In the final scenario, if facial expressions are not improved, default actions can be either automatically take photo anyway or no action to be taken (user determines when to shoot, per legacy cameras).

Two of these processes will be described in more detail below.
