  • Patent number: 10205879
    Abstract: Disclosed are a system and a method for determining enabling or disabling electronic image stabilization (EIS) for a video frame. An image sensor of a camera system captures a video stream that comprises a plurality of video frames. An image processor determines availability of a computational resource that may process application of EIS on each video frame. Simultaneously, the image processor receives motion data of the camera system from a gyroscope. Based on the computational resource availability, a motion frequency threshold is determined. Based on the gyroscope motion data, a motion frequency of each video frame is estimated. The estimated motion frequency is compared to the determined motion frequency threshold. If the estimated motion frequency is greater than the determined motion frequency threshold, application of EIS is disabled. If the estimated motion frequency is less than or equal to the determined motion frequency threshold, application of EIS is enabled.

  • Patent number: 10182188
    Abstract: An image pickup apparatus which is capable of performing automatic adjustment of black balance properly without the need to have a member for fully shielding light. A diaphragm of a lens barrel and an ND filter, which is provided separately from the diaphragm, adjust the amount of light incident on an image pickup device that picks up an image of a subject. Whether the automatic adjustment is possible in present image pickup environment is judged based on evaluation values of a picked-up image obtained in a state where the amounts of incident light are maximized by respective ones of the diaphragm and the ND filter, and a predetermined judgment threshold value which is determined based on a range over which the amount of incident light is adjustable by the diaphragm and a range over which the amount of incident light is adjustable by the ND filter.
