  • Patent number: 11184534
    Abstract: A mobile device includes a display, a gyroscope, a camera, a memory, and a hardware processor. The gyroscope can determine an angle between a plane defined by the display and a plane that is substantially perpendicular to the direction of gravity. The camera can capture an image of a user. The memory stores a set angle and a threshold. The processor determines a difference between the set angle and the angle. The processor further receives the image from the camera. The processor determines a location of the user's lips in the image. In response to determining that the difference remains greater than the threshold for a first time interval or that the user's lips remain open for a second time interval, the processor turns off the display. In response to turning off the display, the processor determines that a third time interval has passed and turns on the display.

  • Patent number: 11172173
    Abstract: A signal processing unit performs preprocessing, demosaic processing and color reproduction processing on an image signal. A control unit detects an image area having undergone a characteristic change exceeding a predetermined change amount, by using an image signal before the reproduction processing and an image signal after the color reproduction processing. The control unit associates area information indicating the detection result of the image area having undergone a characteristic change exceeding a predetermined change amount with the image signal after the color reproduction processing, and records the area information on a recording medium, or outputs the area information to an external device. Thus, it becomes possible to detect an image area where a control change caused by color reproduction processing is unnatural.

  • Patent number: 11108949
    Abstract: An approach is provided for managing a usage of a camera. Based on a second location of the camera being determined to match a first location associated incidents of camera usage that caused harm, the camera is determined to be at a location of concern. The user is notified about the location of concern by a rule-specified, highlighted boundary in a pre-captured first image on the camera display. A person in a pre-captured second image is determined to be within the boundary. The usage of the camera by the user is determined to likely cause a danger to the person. Based on the person being within the boundary and the usage of the camera being likely to cause the danger, a functionality of the camera is disabled so that the camera is not able to capture an image.

  • Patent number: 11070717
    Abstract: In some embodiments, an image processing application executing on a processing device detects an object in an image that is in a field of view of a camera associated with the processing device. The image processing application further determines, based on the object detected in the image, a recommended filter for the image from a list of filters available for filtering the image. The image processing application causes a display device to display a user interface that includes a contextual user interface control. The contextual user interface control indicates that a context-aware image filtering mode is available for the image. Responsive to receiving a selection of the contextual user interface control, the image processing application enables the context-aware image filtering mode by automatically applying the recommended filter to the image to generate a filtered image and causes the display device to display the filtered image.
