    摘要: Systems (490), methods (340), and machine-readable and executable instructions (428) are provided for depth mask assisted video stabilization. Depth mask assisted video stabilization can include creating a first depth mask from a first frame (101, 201) and a second depth mask from a second frame (102, 202) to obtain depth information (342) and defining a first list of feature points (111-1a, 111-2a, 111-3a, 111-4a, 113-1a, 113-2a, 113-3a, 113-4a, 113-5a) from the first frame (101, 201) and a second list of feature points (111-1b, 111-2b, 111-3b, 111-4b, 113-1b, 113-2b, 113-3b, 113-4b, 113-5b) from the second frame (102, 202) (344). Depth mask assisted video stabilization can also include comparing feature points from the first list of feature points (111-1a-111-4a, 113-1a-113-5a) with feature points from the second list of feature points (111-1b-111-4b, 113-1b-113-5b) to find a number of common feature point pairs (111-1a, 111-1b), (111-2a, 111-2b), (111-3a, 111-3b), (111-4a, 111-4b), (113-1a, 113-1b), (113-2a, 113-2b), (113-3a, 113-3b), (113-4a, 113-4b), (113-5a, 113-5b)) (345) and creating a number of motion matrices from the common feature point pairs ((111-1a, 111-1b), (111-2a, 111-2b), (111-3a, 111-3b), (111-4a, 111-4b), (113-1a, 113-1b), (113-2a, 113-2b), (113-3a, 113-3b), (113-4a, 113-4b), (113-5a, 113-5b)) (346). Depth mask assisted video stabilization can also include including the motion matrices in a correction matrix (348) and applying the inverse of the correction matrix to the second frame (102, 202) to perform video stabilization (350).

    摘要: A digital camera takes interleaved photographs of two different kinds. In one example embodiment, the first kind of photograph is taken using a first set of pixels of the camera's electronic array light sensor and has a short exposure time. The second kind of photograph is taken using a second set of pixels and has a long exposure time. More than one of the short-exposure-time photographs is taken while each long-exposure-time photograph is exposed. The two kinds of photographs are used for different purposes. For example, one kind may be used for performing automatic focusing while the other kind is used for displaying in a live view display. In this way, live view may continue while automatic focusing is performed. In another embodiment, one kind of photograph is used for providing a live view display, and the other is used in selecting exposure settings for a final photograph.

    摘要: A gas fuel admission system for use with a gas fuel supply and an internal combustion engine having an engine control unit that produces a desired mass flow signal. The system has a continuously variable gas fuel admission valve having a flow control element and nozzle for metering gas in sonic flow from the gas supply to the engine with insensitivity to the valve discharge pressure. An actuator moves the flow control element relative to the nozzle. The system also has a flow control circuit that responds to the desired mass flow signal from the engine control unit, a gas supply pressure signal from a gas supply pressure sensor, a gas supply temperature signal from a gas supply temperature sensor, and a flow control element position signal from a flow control element position sensor to determine the appropriate flow control element position needed to achieve the desired mass flow at the present engine operating conditions.
