摘要： An apparatus comprising a sensor and a processor. The sensor may be configured to generate a first video signal based on a targeted view from a vehicle. The processor may be configured to classify objects detected in the first video signal. The processor may be configured to generate a second video signal in response to (i) the classified objects and (ii) the first video signal. The second video signal may present a field of view configured to fit a shape of a display emulating a reflective view from a mirror. The second video signal may present a modified group of pixels of the first video signal to mask a flickering effect of the classified objects present in the first video signal when viewing the second video signal on the display.

摘要： An apparatus comprising a first sensor, a second sensor, a processor and a controller. The first sensor may generate a first signal in response to a first type of activity. The second sensor may generate a second signal in response to a second type of activity. The processor may be configured to operate in one of a plurality of power consumption stages. The first power consumption stage waits for a wakeup signal. The second power consumption stage captures a video signal of a targeted view of an environment. The controller may be configured to generate a first intermediate signal if the first type of activity is detected. The controller may generate the wakeup signal if the first intermediate signal is present and the second signal relates to the first signal. The wakeup signal may activate one or more power consuming video processing features of the processor.

摘要： An apparatus comprising a sensor, an interface and a processor. The sensor may be configured to generate a video signal based on a targeted view of a driver. The interface may be configured to receive status information about one or more components of a vehicle. The processor may be configured to generate a control signal in response to a determined field of view of the driver. The control signal may be used to adjust one or more mirrors of the vehicle. The field of view may be determined based on (i) the video signal and (ii) the status information.

摘要： An apparatus comprising an interface and a processing circuit. The interface may be configured to receive (a) a video signal based on a targeted view in a vehicle and (b) one or more status signals from one or more sensors of the vehicle. The processing circuit may be configured to (A) analyze the video signal received from the interface and (B) detect a type of obstruction of a window of the vehicle visible in the video signal in response to (i) a classification of information in the video signal and (ii) one or more of the status signals. The processing circuit may (a) determine a confidence level for the type of obstruction, (b) activate one or more corrective measures when the confidence level is above a pre-defined threshold and (c) adjust the confidence level based on a response of the obstruction to the corrective measures.

摘要： An apparatus comprising a sensor, an interface and a processor. The sensor may be configured to generate a video signal based on a targeted view of an environment. The interface may be configured to receive status information of the apparatus at a time of generation of the video signal. The processor may be configured to (i) detect one or more objects in the video signal, (ii) determine a location of the one or more objects relative to the sensor and (iii) generate metadata. The location of the one or more objects may be based on (i) the status information of the apparatus and (ii) a field of view of the sensor. The metadata may correspond to the location of the one or more objects.

摘要： An apparatus comprising a first sensor, an interface, a second sensor and a processor. The first sensor may be configured to generate a video signal based on a targeted view of a driver. The interface may be configured to receive status information about one or more components of a vehicle. The second sensor may be configured to detect an object within a predetermined radius of the second sensor. The processor may be configured to determine a field of view of the driver based on the status information. The processor may be configured to generate a control signal in response to a cross reference between (i) a field of view of the driver and (ii) the detected object. The control signal may be used to alert the driver if the detected object is not in the field of view of the driver.

摘要： An apparatus includes a camera, a sensor and a processor. The camera may generate a video signal based on a targeted view of a driver. The sensor may generate a proximity signal in response to detecting an object within a predetermined radius. The processor may determine a location of the object with respect to the vehicle, determine a current location of eyes of the driver, determine a field of view of the driver at a time when the proximity signal is received based on the current location of the eyes, determine whether the object is within the field of view using the current location of the eyes, and generate a control signal. The distance may be determined based on a comparison of reference pixels of a vehicle component in a reference video frame to current pixels of the vehicle component in the video frames.

摘要： An apparatus includes a sensor and a processor. The sensor may be configured to generate a first video signal. The processor may be configured to search for a flickering effect in a frame of the first video signal, determine a location and a region of pixels to modify within the frame in response to the flickering effect, determine a modification based on the flickering effect, perform the modification of the region of pixels by determining average values of pixels based on the location of the region of pixels over consecutive frames of the first video signal and generate a second video signal in response to the modification of the region of pixels and the first video signal. The second video signal may present a modified version of the region of pixels to mask the flickering effect when viewing the second video signal on a display.
