ONBOARD DISPLAY SYSTEM
First Claim
1. An onboard display system including at least two control apparatuses, each control apparatus being connected to a display apparatus via a video line that transmits a video signal, each control apparatus achieving (i) a display function that displays a video based on the video signal and (ii) a non-display function that is at least one function different from the display function,a first control apparatus being any one of the at least two control apparatuses,the first control apparatus achieving the display function by executing a video output command that is previously prepared to include an image group of images that are displayed one by one in chronological order, the video output command serving as a command outputting the image group as a video,the first control apparatus comprising:
- a first state acquisition section that acquires a first operating state that is an operating state of the first control apparatus itself;
a first state output section that outputs the first operating state acquired by the first state acquisition section to a second control apparatus via an onboard line that is a transmission line transmitting a signal, the second control apparatus being any one of the at least two control apparatuses excluding the first control apparatus, the second control apparatus being provided as an independent body separated from the first control apparatus and connected with the first control apparatus via the onboard line;
a second state acquisition section that acquires a second operating state that is an operating state of the second control apparatus;
a state determination section that determines whether a display prioritization state or a non-display prioritization state takes place,the display prioritization state taking place when both the first operating state and the second operating state prioritize realization of the display function over realization of the non-display function,the non-display prioritization state taking place when at least one of the first operating state and the second operating state prioritizes realization of the non-display function over realization of the display function; and
an image update section that performs an image update control,the image update control executing an update of the images, which are included in the video displayed in the display apparatus in chronological order when the state determination section determines that the display prioritization state takes place,the image update control suspending the update of the images when the state determination section determines that the non-display prioritization state takes place.

Abstract
An onboard display system includes two display groups; each display group includes a display apparatus and a control apparatus. The first control apparatus of the first display group includes the following: a first state acquisition section that acquires a first operating state of the first control apparatus itself; a second state acquisition section that acquires a second operating state of the second control apparatus of the second display group; a state determination section that determines whether a display prioritization state takes place based on the first operating state and the second operating state; and an image update section that updates, in chronological order, images in a video displayed in the first display apparatus of the first display group when the display prioritization state takes place or that suspends the updating when the display prioritization state does not take place.

4. An onboard display system including at least two control apparatuses that are connected via an onboard line that is a transmission line transmitting a signal, each control apparatus being connected to a display apparatus via a video line which transmits a video signal,
each control apparatus achieving a display function that displays a video based on the video signal and a non-display function that is at least one function different from the display function, each control apparatus achieving the display function by executing a video output command that is previously prepared to include (i) an image group of images and (ii) a display priority level indicating a degree of a priority of each of the images against the realization of the non-display function, the images being displayed one by one in chronological order, the video output command serving as a as a command that outputs the image group as a video and updating the images each time a predetermined clock time comes, each control apparatus comprising: -
a video interpretation section that acquires the video output command and determines whether a display prioritization state takes place or not based on a result of analyzing the acquired video output command, the display prioritization state taking place when realization of the display function is prioritized over realization of the non-display function; and a function control section that performs a display prioritization control, wherein when the video interpretation section determines that the display prioritization state takes place, the display prioritization control suppresses realization of the non-display function while securing a resource necessary for realization of the display function to realize the display function preferentially. - View Dependent Claims (5, 6, 7, 8, 9, 10)
