  • Patent number: 10739838
    Abstract: A smart camera system including an image sensor and a controller is presented. The image sensor generates video data that is initially at a bit rate of a pre-determined bit rate value. The controller is coupled to the image sensor to transmit the video data. The controller includes a processor operating at a clock rate of a first frequency. The processor is coupled to memory, the memory including instructions, which when executed by the controller causes the smart camera system to perform operations. The operations include dynamically scaling the clock rate of the processor to an adjustment frequency in response to receiving an input to change the bit rate of the video data. The adjustment frequency for the clock rate of the processor based, at least in part, on the input bit rate value. The operations further include changing the bit rate to the input bit rate value.

  • Patent number: 10602139
    Abstract: A system includes an image sensor and a sending controller. The image sensor to generate video data at a source bit rate. The sending controller is coupled to the image sensor to transmit communication data representative of the video data. The sending controller includes one or more processors coupled to memory. The memory includes instructions, which when executed by the sending controller causes the system to perform operations. The operations include determining a first bit rate to encode a first portion of the video data, generating a first video packet representative of the first portion by encoding the first portion at the first bit rate, and determining whether to transmit the first video packet as the communication data with the sending controller based on at least one of a transmission rate threshold, a transmission interval threshold, or a buffer fill threshold.

The sending controller is coupled to the image sensor to transmit communication data representative of the video data. The sending controller includes one or more processors coupled to memory. The memory includes instructions, which when executed by the sending controller causes the system to perform operations. The operations include determining a first bit rate to encode a first portion of the video data, the first bit rate being different than the source bit rate. The operations also include generating a first video packet representative of the first portion by encoding the first portion at the first bit rate. The first video packet is stored in a video packet buffer of the system.

  • Patent number: 8408821
    Abstract: An imaging system includes an image sensor and an optical filter. The image sensor captures image data in response to incident light. The optical filter filters the light and includes a dual window transmission spectrum. The dual window transmission spectrum includes a first transmission window having a first pass band aligned to pass visible light and a second transmission window having a second pass band overlapping with an absorption band of infrared light in Earth's atmosphere.
