Abstract

A display control system for a gaming machine is described. The display control system allows a gaming machine controller to directly control attributes of one or more video displays coupled to a gaming machine. Display attributes can be adjusted to account for different machine states which can occur when the gaming machine is operating in an attract mode, game play mode and tilt mode. A few examples of display attributes which can be controlled include but are not limited to power on or off, input source selection, contrast control, brightness control and color temp control.

First claim

What is claimed is:

1. A gaming machine comprising:
a cabinet including an entry that provides access to an interior of the cabinet, a locking mechanism coupled to the entry and a plurality of security sensors wherein at least one of the plurality of security sensors is used to detect access to the interior of the cabinet;
a power supply, disposed within the interior of the cabinet, configured to receive power from an external power source;
a power-off security device disposed within the interior of the cabinet coupled to one or more of the plurality security sensors configured to monitor access to the cabinet when the power supply is unpowered by the external power source;
a display, coupled to the cabinet, configured to output content associated with play of a wager-based game on the gaming machine, the display including 1) first firmware configured for adjusting display attributes of an entire screen of the display in response to manual attribute adjustment settings, 2) a manual input interface used to provide the manual attribute adjustment settings to the first firmware; 3) second firmware configured for adjusting the display attributes in response to automated attribute adjustment commands, 4) automated commands receiving interface which receives the commands and provides the received commands to the second firmware, and 5) a plurality of video inputs;
a non-volatile memory, disposed within a locked box within the interior of the cabinet, configured to store gaming software used to generate the wager-based game on the gaming machine;
a power-hit tolerant memory, disposed within the locked box within the interior of the cabinet, configured to store crucial data associated with play of a plurality instances of the wager-based game; and
a gaming machine controller, including a processor and a memory, disposed within a locked box within the interior of the cabinet, coupled to the power supply, the power-off security device, the plurality of security sensors, the display including one or more of the video inputs and the automated commands receiving interface of the display, the non-volatile memory and the power-hit tolerant memory, the gaming machine controller being configured to 1) control play of the wager-based game; 2) validate the gaming software, 3) verify integrity of crucial data stored within the power hit tolerant memory, 4) monitor the power-off security device and the plurality of security sensors to detect tilt conditions; 5) store the crucial data associated with a plurality of instances of the wager-based game to the power-hit tolerant memory wherein the crucial data at least allows portions of the wager-based game to be re-displayed for a particular instance of the wager-based game after the particular instance of the wager-based game is complete; 6) after a power interruption, determine that a power-hit occurred prior to a completion of the play of the particular instance of the wager-based game and 7) restore a game state of the wager-based game to the particular instance of the wager-based game that occurred just prior to the power interruption;
wherein the gaming machine controller includes gaming display control logic responsive to internal game states and internal non-game states of the gaming machine and configured to determine when to automatically cause changes to the display attributes of the entire screen of the display in response to the internal game states and the internal non-game states of the gaming machine using the commands sent to the display via the automated commands receiving interface.

2. The gaming machine of claim 1 , wherein the internal non-game states of the gaming machine include at least one of a tilt state and an attract state.

3. The gaming machine of claim 1 , wherein the gaming machine controller, in response to detecting one of the internal states of the gaming machine is changed from one of a game state to an attract state or the attract state to the game state, changes one or more of the display attributes using the commands.

4. The gaming machine of claim 3 , wherein the changes to one or more of the display attributes includes changing one or more of a brightness, contrast, color temperature attributes of the display or combinations thereof.

5. The gaming machine of claim 1 , wherein the gaming machine controller, in response to detecting one of the internal states of the gaming machine is changed from a first game state to a second game state, changes one or more of the display attributes using the commands.

6. The gaming machine of claim 5 , wherein the second game state includes outputting an indication of a bonus to the display.

7. The gaming machine of claim 1 , wherein detection by the gaming display control logic of a change to one of the internal game states and the internal non-game states of the gaming machine causes the gaming machine controller to automatically change a value of one or more of a brightness, a contrast and/or a color temperature attribute of the entire screen of the display using the commands sent to the display via the automated commands receiving interface.

8. The gaming machine of claim 7 , wherein the value is automatically changed in a single step from its current value to a predetermined new value.

9. The gaming machine of claim 7 , wherein the value is gradually automatically changed in a plurality of steps from its current value to a predetermined new value.

10. The gaming machine of claim 1 , wherein the gaming machine controller is further configured to determine a current length of a game play session including play of the wager-based game and to set the display attributes of the entire screen of the display based upon the determined current length of the game play session.

11. The gaming machine of claim 10 , wherein one or more of a value of a brightness, a value of a contrast, a value of a color temperature or combinations thereof are changed based upon the determined current length of the game play session.

12. The gaming machine of claim 1 , wherein the gaming machine controller is configured, prior to determining whether to change the display attributes of the entire screen of the display in response to detection of a change in at least one of the internal game states and internal non-game states of the gaming machine, to send a command to the display requesting current values of the display attributes where the request is satisfied without altering what is currently displayed on the entire screen of the display.

13. The gaming machine of claim 1 , wherein the gaming machine controller is further configured to turn on or place the display in a stand-by mode using the commands.

14. The gaming machine of claim 1 , wherein the gaming machine controller is further configured to a select, using the commands, one of the plurality of video inputs from which to receive video content.

15. The gaming machine of claim 1 , wherein, in response to the gaming display control logic detecting a change for at least one of the internal game states and internal non-game states of the gaming machine, the gaming machine controller determines new display attributes corresponding to the detected change, reconfigures the entire screen of the display with the new display attributes using the commands and stores the new display attributes as crucial data to the non-volatile memory.

16. The gaming machine of claim 1 , further comprising: a second display, coupled to the cabinet, the second display including 1) third firmware for manually adjusting second display attributes of an entire screen of the second display, the manual adjustin
