A work machine display system includes an image acquisition unit and a display control unit. The image acquisition unit acquires a captured image in which surroundings of a work machine are portrayed. The display control unit generates a display signal in order to display a display image including a peripheral image based on the captured image on a screen of a display unit after transition when the display control unit receives a transition signal for screen transition while the peripheral image is displayed on the display unit.

Work machine display system and work machine display method

A working machine display system includes: a monitor including a display unit; a first monitor control unit connected to the monitor and configured to generate a screen for displaying various kinds of information of a working machine and output the screen as a signal to the monitor; a second monitor control unit connected to the monitor and configured to generate a screen for displaying special information of the working machine and output the screen as a signal to the monitor; and a return switch. The monitor displays the various kinds of information in accordance with a signal output from the first monitor control unit and displays the special information in accordance with a signal output from the second monitor control unit, and the return switch causes a transition from a display screen of the special information to a display screen of the various kinds of information.
