Estimating the term…
Methods, systems, and apparatuses are provided for measuring a display latency. A video capturing device is configured to capture a video of a reference light flash of a light emitter of a computing device. In the same video, the video capturing device is configured to capture a flash of a predetermined image displayed in a reference frame on a display screen coupled to the computing device. The video is analyzed to determine a time difference between the reference light flash of the light emitter and the flash of the predetermined image on the display screen. The determined time difference is compared with a reference time difference to determine a display latency, and the display latency may be provided to a user. In this manner, a display latency may be determined accurately and with readily available hardware, thus reducing the need to rely on expensive and specialized measuring equipment.
