[0044] FIG. 9 illustrates one embodiment of a method 900 of the present invention for detecting a freeze frame condition in a WiFi camera. In a first step 902, a WiFi camera is used to capture a plurality of images. For example, a camera including lens 212, a video transmitter 214, and a video decoder 215 may capture a plurality of images.

[0045] Next, in step 904, one of the images is compared to another one of the images. For example, a video buffer from a lens to digital signal processor and WiFi output may be compared with a previous frame for 30 frames.

[0046] In a final step 906, the freeze frame condition is detected as a result of determining that a level of similarity between the two captured images exceeds a threshold level. For example, if a pixel-to-pixel comparison of the two images shows that more than a threshold number or percentage of pixels are identical in the two images, then it may be determined that there is a freeze frame condition.

[0047] While this invention has been described as having an exemplary design, the present invention may be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains.
