| 发明名称 | Identifying an object in a field of view | ||
| 摘要 | The technology disclosed relates to identifying an object in a field of view of a camera. In particular, it relates to identifying a display in the field of view of the camera. This is achieved by monitoring a space including acquiring a series of image frames of the space using the camera and detecting one or more light sources in the series of image frames. Further, one or more frequencies of periodic intensity or brightness variations, also referred to as ‘refresh rate’, of light emitted from the light sources is measured. Based on the one or more frequencies of periodic intensity variations of light emitted from the light sources, at least one display that includes the light sources is identified. | ||

| 主权项 | 1. A method of recognizing a display in a field of view of a camera, the method including: acquiring a series of image frames from the camera, the image frames including an object; detecting one or more light sources in the series of image frames; analyzing the one or more light sources across the series of image frames for periodic brightness variations to determine a refresh rate of the one or more light sources; and recognizing an object in the series of images as a display that includes the one or more light sources, the recognizing based on the refresh rate determined from the periodic brightness variations. | ||
