Abstract
A camera including a first circuit and a second circuit. The first circuit may be configured to perform image signal processing and control one or more functions of the camera using image signal processing related information and encoding related information. The second circuit may be configured to encode image data using the image signal processing related information and camera settings information. The first circuit may be further configured to pass the image signal processing related information and the camera settings information to the second circuit. The second circuit may be further configured to pass the encoding related information to the first circuit.
Claims22
A camera comprising:
- a first circuit configured to perform image signal processing and control one or more functions of said camera using image signal processing related information and encoding related information;
- and
- a second circuit configured to encode image data using said image signal processing related information and camera settings information, wherein (i) said first circuit is further configured to pass said image signal processing related information and camera settings information to said second circuit and (ii) said second circuit is further configured to pass said encoding related information to said first circuit and to adjust one or more encoding parameters based upon one or more of focus information, exposure information and flash information.
A method of video bit rate control comprising the steps of:
- performing an image signal processing operation using encoding related information and camera settings information;
- performing an image encoding operation using image signal processing related information and said camera settings information;
- controlling one or more functions of a camera in response to said image signal processing related information and said encoding related information, wherein said image signal processing related information is generated while performing the image signal processing operation and passed to the image encoding operation and a control module of the camera, the encoding related information is generated during the image encoding operation and passed to the image signal processing operation and the control module of the camera and the control module of the camera is configured to pass the camera settings information to the image signal processing operation and the image encoding operation;
- and
