  • Patent number: 12079423
    Abstract: The present disclosure describes systems and methods for rapidly capturing user input. Some embodiments of the present disclosure may rapidly capture user input for psychometric analysis applications. For example, a Likert scale may be used to capture the intensity of feelings of a respondent for a given item or question, and therefore can be applied to multiple domains including psychology and social sciences, business and marketing, etc. According to techniques described herein, a visual display screen may prompt respondent input (e.g., via an input prompt, question, statement, etc.). A touch-sensitive input area of the visual display screen may capture respondent input. The touch-sensitive input area may include an input bar and an input position (e.g., a slider). A respondent may control the input position along the input bar (e.g., using a finger), such that the input capture system may efficiently capture, determine, and record the input.

    Abstract: This application discloses a method for adjusting image luminance performed at an electronic device. The method includes: determining that an original luminance of a target pixel in an image is lower than a luminance threshold of the image, the luminance threshold being determined according to luminance of pixels in the image; in accordance with the determination: obtaining a luminance distribution intensity of pixels adjacent to the target pixel in the image; determining a luminance difference between the luminance threshold and the luminance distribution intensity of the adjacent pixels; and adjusting the original luminance of the target pixel to a corresponding target luminance according to the luminance difference. By preserving the changing characteristic of relative luminance between the target pixel and the adjacent pixel, the luminance adjustment is more consistent with the luminance distribution of the image, thereby achieving a technical effect of improving the luminance adjustment on an image.
