    摘要: A video camera includes a light collection array including a plurality of light collection cells configured to collect light from a scene and a processor coupled to the light collection array. The processor is configured determine a brightness of the scene based on the light collected by the light collection array from the scene. Based on the determined brightness, the processor is configured to determine if the brightness of the scene requires a light collection time of each cell to be less than a flicker on time of a light source lighting the scene so that the light collection array collects a sufficient amount of light so that a brightness of a video stream or a still image is substantially at a predetermined level. If the light collection time is determined to be less than the flicker on time to maintain brightness of the video stream or the still image at the predetermined level and if the brightness of the scene is less than a predetermined brightness, the processor is configured to set the light collection time at the flicker on time of the light source. If the light collection time is determined to be less than the flicker on time to maintain brightness of the video stream or the still image at the predetermined level and if the brightness of the scene is at, or greater than, the predetermined brightness, the processor is configured to set the light collection time less than the flicker on time of the light source.

    摘要: A system and method for optimizing a video stream from a high frame rate image sensor. The high frame rate video stream is split into two separate video streams so that one video stream can be shown to a user or recorded, while the other video stream can be processed. The processed video stream can be analyzed for sharpness to adjust for focus or it can be imaged with or without an optical filter and used to enhance the appearance of the other video stream.

    摘要: A system and method for seamlessly switching between various bus interfaces on a device, regardless of the application using the device. The change of the bus interface being used is completely transparent to the application using the device. A system in accordance with an embodiment of the present invention creates a Physical Device Object (PDO) that is unique for each device, regardless of which bus interface is used by the device. An application using that is essentially linked to this unique PDO. In one embodiment, an exhaustive list of various devices connected to the different bus interfaces is created. This is done by creating a bridge between the enumerators for the various buses and a class enumerator.

    摘要: A method and apparatus for real time adjustment of wireless transmission in a media device (e.g., webcam), as opposed to a server or computer. In one embodiment, the adjustment, or dynamic tuning, involves tracking available bandwidth of the radio signaling rate and varying one of the retry rate, compression and frame rate. Also, the adjustment can be made on the basis of forecasts based on past behavior. A tracking and control algorithm is used to modulate the video bit-rate from the camera with the dynamic bit-rate available in a WiFi link.
