Automatic focus detection with relative threshold-aware cell visibility for a scrolling cell collection

An apparatus comprising:

• a memory;
• a display device to render a graphical user interface (GUI);
• and
• a processing device, operatively coupled to the memory and the display device, to:
• render the GUI;
• identify visible cells of a plurality of cells of a reference frame, the visible cells rendered in a graphical user interface (GUI) displaying at least a portion of the reference frame;
• determine, for each visible cell of the visible cells, a distance value indicating a distance to a focus threshold in the reference frame that the visible cell has traveled since the visible cell became visible in the GUI;
• and
• modify a behavior of the visible cells in the GUI based on the distance value of each of the visible cells.

A non-transitory machine-readable storage medium storing instructions which, when executed, cause a processing device to perform operations comprising:

• identifying visible cells of a plurality of cells of a reference frame, the visible cells rendered in a graphical user interface (GUI) displaying at least a portion of the reference frame;
• determining, by the processing device rendering the GUI and for each visible cell of the visible cells, a distance value indicating a distance to a focus threshold in the reference frame that the visible cell has traveled since the visible cell became visible in the GUI;
• and
• modifying a behavior of the visible cells in the GUI based on the distance value of each of the visible cells.
