  • Patent number: 8462227
    Abstract: A method includes determining white balance calibration color ratios for a plurality of illumination sources by using a representative camera of a given type to establish a set of ratios. Because the ratios are fixed for the given camera type, a plurality of cameras of the type may store the fixed ratios, and calibrate by measuring only the reference illumination source. Later white balancing is achieved by using the measured reference illumination source color ratios and the stored fixed ratios as scaling factors to map from the reference illumination source to any other illumination source. The method includes an off-line advance calibration procedure to obtain the fixed ratios, an on-line per camera calibration procedure to obtain color ratios for the reference source, and subsequent white balancing which uses the fixed ratios/scaling factors and the reference source color ratios.

  • Publication number: 20130138977
    Abstract: Briefly, a method and apparatus adjusts the power consumption level of an integrated circuit by dynamically scaling the clock frequency based on the real-time determined power consumption level. In one example, the method and apparatus changes an actual clock frequency of the integrated circuit to an effective clock frequency based on the maximum clock frequency and the difference between the threshold power consumption level and the actual power consumption level of the integrated circuit in the previous sampling interval. In one example, an effective clock frequency of the integrated circuit in the current sampling interval is determined. In one example, the difference between the maximum and effective clock frequencies in the current sampling interval is proportional to the difference between the threshold and actual power consumption levels in the previous sampling interval. The actual clock frequency of the integrated circuit is changed to the determined effective clock frequency.

  • Patent number: 8443225
    Abstract: Embodiments described herein include a method and system for synchronizing clocks between coupled integrated circuits (ICs) in a computer system. According to an embodiment, a dedicated timing pin is provided on a first IC. The first IC configures a second IC to change a pin assignment, so that the second IC interprets a signal sent on the timing pin by the first IC and received on the reassigned pin as a request to transmit a return signal. The return signal is received on the timing pin. The return signal is used to determine whether timing should be adjusted by the first IC. In an embodiment a clock and data recover (CDR) circuit compares the signal sent to the signal received in order to make the determination. In an embodiment the first IC is a processor-based device, and the second IC is a memory device controlled by the first device.

  • Patent number: 8441551
    Abstract: Circuitry, apparatus and methods provide flicker detection and improved image generation for digital cameras that employ image sensors. In one example, circuitry and methods are operative to compare a first captured frame with a second captured frame that may be, for example, sequential and consecutive or non-consecutive if desired, to determine misalignment of scene content between the frames. A realigned second frame is produced by realigning the second frame with the first frame if the frames are determined to be misaligned. Luminance data from the realigned second frame and luminance data from the pixels of the first frame are used to determine if an undesired flicker condition exists. If an undesired flicker condition is detected, exposure time control information is generated for output to the imaging sensor that captured the frame, to reduce flicker. This operation may be done, for example, during a preview mode for a digital camera, or may be performed at any other suitable time.

    Abstract: A method and system are described for low-latency video. In the method a frame, selected from a group of frames, is divided into P-regions and an I-region based on an assigned refresh pattern in a refresh loop. An I-region bit budget and a P-region bit budget are determined. Quantization parameters are determined using the I-region bit budget and the P-region bit budget. Macroblocks of the selected frame are encoded based on the quantization parameters. The I-complexity and P-complexity are updated and a new frame bit budget is determined. The dividing, determining of the I-region bit budget, determining of the P-region bit budget, determining of quantization parameters and encoding are repeated for each remaining frame in the group of frames.
