  • Patent number: 11947721
    Abstract: In a vehicle display control apparatus, a line of sight of a driver is detected, and a visual field of the driver is estimated from the detected line of sight. Then, display information displayed on a display unit of a vehicle is controlled based on a positional relationship between the estimated visual field and the display unit. As a result, the information to be displayed can be controlled in accordance with a recognition level of the driver for the information displayed on the display unit based on the positional relationship between the visual field of the driver and the display unit, and the information can be displayed in a mode easily recognized by the driver.

  • Patent number: 11927757
    Abstract: An electronic device may have a display panel with an array of display pixels. Light from the display panel may be focused by a lens assembly towards a viewer. The presence of the lens assembly may cause geometric distortion for a viewer viewing images on the display through the lens assembly. To mitigate geometric distortion, geometric distortion compensation may be performed in the electronic device. The electronic device may include both a fixed lens element and a removable lens element in the lens assembly. The removable lens element may be changed, allowing the distortion function associated with the lens assembly to change over time. To dynamically compensate for geometric distortion caused by a lens assembly with a removable lens, ray tracing may be used to determine the geometric distortion caused by the lens assembly depending upon the particular removable lens that is present in the lens assembly.

  • Patent number: 11269260
    Abstract: A method includes using an illumination device to illuminate an object with electromagnetic radiation produced by a radiation source, and using a detector device to capture a respective intensity distribution in a diffraction image produced by the object in a plurality of measurement steps. The measurement steps differ from one another with respect to the illumination setting set by the illumination device. The method also includes determining at least one characteristic variable that is characteristic for the object on the basis of an iteratively performed comparison between the measurement values obtained within the scope of the measurement steps and model-based simulated values. The model-based simulated values are ascertained on the basis of a multiple layer model, in which the object is modeled by a multiple layer structure made of layers that are respectively separated from one another by an interface, wherein a location-dependent reflectivity is assigned to the interfaces.

  • Patent number: 11249594
    Abstract: A projector can include a projection section that projects an image on a projection surface, a detection light radiation section that radiates detection light in a direction corresponding to the projection surface. The projector can also include an adjuster that adjusts the direction of the detection light relative to the projection surface, and an imager and a controller that can detect reflected light resulting from the detection light to detect operation performed on the projection surface. The controller can evaluate whether or not the detection state of the reflected light corresponds to a specific state. If the detection is in the specific state, the adjuster can adjust the direction of the detection light based on a result of the evaluation.

  • Patent number: 11228740
    Abstract: A novel high efficiency image projection system includes a beam-steering modulator, an amplitude modulator, and a controller. In a particular embodiment the controller generates beam-steering drive values from image data and uses the beam-steering drive values to drive the beam-steering modulator. Additionally, the controller utilizes the beam-steering drive values to generate a lightfield simulation of a lightfield projected onto the amplitude modulator by the beam-steering modulator. The controller utilizes the lightfield simulation to generate amplitude drive values for driving the amplitude modulator in order to project a high quality version of the image described by the image data.

  • Patent number: 11137593
    Abstract: A laser beam display device that can dynamically control the resonant frequency of a mirror is provided. The increase the reliability of a device by controlling the resonant frequency of a mirror instead of requiring components of a display device to react to changes in the resonant frequency of a mirror. A controller can drive a mirror with an input signal, receive a signal or data indicating a target resonant frequency, and bias the input signal to control the resonant frequency of the mirror. In some embodiments, the controller can also receive a feedback signal from a mirror indicating a current resonant frequency. The controller can also bias the input signal to increase or decrease the current resonant frequency. By dynamically controlling the resonant frequency of a mirror, a device can minimize any difference between the current resonant frequency detected in a feedback signal and the target resonant frequency.
