Abstract: A method of evaluating image data representative of a display icon relative to reference data representative of a reference icon to determine whether the display icon matches the reference icon, the reference icon comprising at least first and second image regions which are distinct in image contrast from one another, the image data defining pixel values corresponding to pixels of the display icon, the method comprising: for each of a plurality of areas of the display icon, categorizing that area as corresponding to one or none of the image regions based on a comparison between the pixel value or values for that area and at least a plurality of pixel-value ranges defined in relation to the reference icon, the pixel-value ranges corresponding to respective said image regions and defined so as to ensure sufficient image contrast between areas categorized as corresponding to different said image regions; generating categorization information representative of the image data indicating how the plurality of areas have been categorized; and determining whether the display icon matches the reference icon based on a comparison of the categorization information and the reference data.

Abstract: A communication system including a master apparatus and a slave apparatus, the slave apparatus, in an upstream period, transmits a slave data signal to the master apparatus based on a slave clock signal; and the master apparatus: during reception of the slave data signal, extracts timing information from the slave data signal and adjusts a phase and/or frequency of a master clock signal or a definition thereof relative to a reference phase and/or frequency based on the extracted timing information to enable decoding of the received slave data signal; in a downstream period, transmits a master data signal to the slave apparatus based on the master clock signal according to the adjustment; and adjusts the phase and/or frequency of the master clock signal during transmission of the master data signal to reduce a change in the phase and/or frequency of the master clock signal effected according to the adjustment.
