  • Patent number: 10650726
    Abstract: A timing controller includes a count control circuit, a pulse width detector, and a pulse generator. The count control circuit receives an external enable signal. Pulses of the external enable signal include an effective and a blank period of image data. The count control circuit counts pulse widths of each of the pulses. The pulse width detector receives the counted pulse widths, compares a pulse width of a present pulse with pulse widths of previous pulses, and detects a pulse width of a previous pulse that has a pulse width smaller than the pulse width of the present pulse. The pulse generator generates three output pulses having pulse widths that are one-third a period of the detected previous pulse. The pulse generator outputs the first, second and third pulses as an internal enable signal.

  • Patent number: 10635380
    Abstract: An HMD (10a) generates region information indicating a region having, as an axis, a line which passes through the position of the HMD (10a) and that of a wireless I/F (105a). The HMD acquires position information of each of wireless I/Fs of other image processing apparatuses (11b, 11c). The HMD determines if the position indicated by the acquired position information is included in the region indicated by the region information. The HMD selects one of the wireless I/F (105a) and other wireless I/Fs as a wireless communication partner according to the determination result, and receives images via wireless communication with the selected wireless I/F.

  • Patent number: 10620748
    Abstract: A device for providing a touch-based user interface is disclosed. The device comprises a screen, a camera, and processor. The camera images a reflection of the screen by a cornea of a user of the device. The processor displays at least one user-interface element on the screen, detects that a finger of a hand touches or is about to touch the screen, estimates a trajectory of the finger, and determines an intended location of touch of the finger on the screen. The trajectory of the finger is estimated by analyzing a sequence of images of the reflection. The intended location of touch is determined based on the estimated trajectory of the finger.
