  • Patent number: 11831996
    Abstract: A system for generating high dynamic range (HDR) imagery obtains a history frame associated with a first timepoint and with a first set of image capture parameters. The system obtains an image frame associated with a particular set of image capture parameters and captured at a second timepoint that is subsequent to the first timepoint, and the particular set of image capture parameters comprises the first set of image capture parameters or a second set of image capture parameters. The system generates a normalized image frame by applying a normalization operation to the image frame. The normalization operation may be determined based upon the particular set of image capture parameters. The system generates a weight map based upon at least the normalized image frame and generate an HDR image frame based upon the normalized image frame, the history frame, and the weight map.

  • Patent number: 11812156
    Abstract: A device and a method reduce a backlight effect on a camera of a robot in consideration of a situation of the robot. The device acquires a surrounding image, communicates with a system of the robot to obtain a current state value of the robot, and calculates a parameter value of the camera based on the current state value of the robot. Thus, the device precisely corrects the parameter of the camera based on an environment where the robot is actually located, thereby reducing the backlight effect on the camera.

  • Patent number: 11700349
    Abstract: A camera system and method provide a trailing motion blur effect without the use of a flash. In one embodiment, a variable light-transmissive filter is positioned in front of an image sensor. While the light-transmissive property of the filter is lower, the blurred image of the object in motion is produced. The light-transmissive property of the filter is increased during the exposure in order to produce a clearer image of the object. In a method, a plurality of images taken in rapid succession are combined to produce a clear image of the object with a trailing blurred image of the object.

  • Patent number: 11678061
    Abstract: An image pickup apparatus capable of suppressing occurrence of a delay in an exposure control when the exposure control is performed by selectively changing an exposure condition among a plurality of exposure conditions. In a transition period from when the exposure control for changing a first exposure condition according to a target exposure at a time of image pickup of the subject is started until the exposure reaches the target exposure, another exposure condition other than the first exposure condition is changed so that an exposure changing speed of the first exposure condition is compensated for. When the exposure is changeable based on a program diagram and when the first exposure condition is changed, control is provided so that a second exposure condition to be changed immediately after changing the first exposure condition is used to compensate for the exposure changing speed of the first exposure condition.

For this purpose, on a client side, the content of camera control is described in file-transfer protocol description, and the description is transferred to a camera server on the Internet via a browser. The camera server interprets the description, controls a camera in accordance with the designated content, to perform image sensing, and returns the obtained video image as the content of a file to the client. The client performs various controls while observing the video image. When a desired angle has been found, the client instructs to register the angle in a bookmark, then angle information displayed at that time is registered. Thereafter, when the user of the client can see the video image obtained on the same image-sensing conditions by merely select-designating the angle information registered in the bookmark.
