Scanning Device Function Prioritization for Sheet Mode

The patent applies local quality by displaying different visual styles for different types of functions on the display unit. Specifically, functions executable in the current scanning mode are displayed in a first style (e.g., with icons or highlighted), while functions not executable in the current mode are displayed in a second style (e.g., with different icons or dimmed). This visual differentiation allows users to easily distinguish selectable functions from non-selectable ones without hiding any function options, thus resolving the contradiction between providing comprehensive function options and ensuring ease of operation.

The patent employs color changes or visual style changes to indicate the selectability of functions. Functions that can be executed in the current scanning mode are displayed with a first visual style (e.g., normal color, highlighted, or with checkmark icons), while functions that cannot be executed are displayed with a different visual style (e.g., grayed out, dimmed, or with different icons). This visual differentiation prevents users from mistakenly selecting non-selectable functions while still displaying all available function information, thus resolving the contradiction between maintaining full function information and ensuring selection accuracy.
