Abstract: A method includes displaying an image on a first area of a touch-sensitive electronic display and receiving touch input on a second area of the display, comprising the first area. A gesture type is detected from the touch input by detecting a larger component of motion of the touch input along one of first and second axes of the display than along the other of the axes. Detecting a second gesture type comprises detecting a larger component of motion of the touch input along the other of the axes than along the one of the axes. If the gesture type is the first gesture type, a display characteristic of the image is adjusted, during displaying the image. If the gesture type is the second gesture type, the display ceases to display the image and displays a further image. A computing system is provided.

Abstract: Examples of the present disclosure relate to a method for reducing artefacts caused by the presence of flicker during capture of a video. A sequence of frames of the video are captured, the frames each comprising a plurality of predefined regions each comprising a plurality of pixels. A time-varying oscillation of the flicker is characterized based on variations, across the sequence of frames, of data relating to pixel intensities in at least one said region. Based on the characterizing of the time-varying oscillation of the flicker, a flicker correction is applied to a frame of the video.

Abstract: A method of selecting at least one region of interest within an image includes the selection of a preliminary region having a preliminary border. The selection uses one or more characteristics of the image. An inner probability distribution of color components is determined within the preliminary region and an outer probability distribution of color components outside the preliminary region. The preliminary border is adjusted in dependence on the probability distributions, the adjusted border defining the at least one region of interest.

Abstract: A method of controlling in a display device screen brightness and strength of dynamic range compression of display data in dependence on ambient light level. Ambient light level values are required from one or more ambient light sensors. The ambient light level values are averaged using a first method to obtain a first average value and using a second, different method to obtain a second average value. The first average value is used for controlling the screen brightness and the second average value is used for controlling the strength of the dynamic range compression.
