  • Patent number: 11716451
    Abstract: A color correction method and a color correction system that executes the color correction method are provided. A correction image is projected on a projection screen based on a predefined value. A single frame of the correction image includes multiple regions. The multiple regions include multiple hue regions with different hues and multiple lightness regions with different lightness corresponding to the hues, or the multiple regions include multiple gray-scales regions with different gray-scales. A captured image is obtained by capturing the projection screen. Optical information of the captured image is detected. The optical information is compared with the predefined value to obtain an uneven color region that does not conform to the predefined value. The uneven color region is adjusted so that the optical information of the uneven color region conforms to the predefined value. The time for color correction can be greatly reduced accordingly.

  • Patent number: 11528528
    Abstract: The invention provides a method and a system for controlling a projector. The control method includes: obtaining a first trigger rule and a first to-be-executed action corresponding to the first trigger rule. The first trigger rule and the first to-be-executed action respectively include at least one of a plurality of combinable elements. The control method includes: determining whether the first trigger rule is satisfied and controlling the projector to execute the first to-be-executed action when the first trigger rule is determined as being satisfied. The control system includes a projector and a control device configured to execute the control method. The control method and system of the invention provide more diverse and flexible rules and action generation mechanisms, thereby implementing effects of product differentiation and intelligent operation.

  • Patent number: 10032012
    Abstract: A storage device capable of fingerprint identification includes a first storage, a first controller and a second storage. The first storage is configured to store a registered fingerprint. The first controller is configured to compare the registered fingerprint with an input fingerprint, wherein the input fingerprint is obtained in response to a touch event. The second storage is configured to store a data. The data is, in response to a fingerprint comparison result, selectively allowed to be accessible or prohibited from being accessible to a host.
