Display control apparatus, display control method, recording medium, and display system that corrects distortion based on viewpoint information and a display position

A display control method, comprising:

• determining a display position that is a position, on a screen, at which an image of content is displayed;
• determining a viewer position that is a position of a viewer who views the image, wherein the viewer position is determined based on a display mode indicating a priority between plural seats, the plural seats including a driver's seat and a passenger seat, wherein, when the display mode indicates an equality mode between the driver's seat and the passenger seat, the viewer position is determined as a virtual intermediate position between the driver's seat and the passenger seat;
• determining, according to the viewer position, transformation information used to correct the image such that a distortion in the image appears reduced to the viewer when the viewer views the image displayed at the display position on the screen;
• and
• rendering a correction image that is an image obtained by correcting the image using the transformation information to generate correction-image rendering data that is output to the screen, wherein the image of the content displayed on the screen is viewable from plural seats.

A non-transitory computer-readable recording medium that records therein a display control program that operates a control circuit of a display control apparatus as a distortion correction selecting circuit and a distortion correction processor,

• the distortion correction selecting circuit
• determining a display position that is a position, on a screen, at which an image of content is displayed,
• determining a viewer position that is a position of a viewer who views the image, wherein the viewer position is determined based on an attribute of the content and positions of plural seats and wherein the viewer position is determined as one of a driver's seat position, a passenger seat position, or a virtual intermediate position between the driver's seat and the passenger seat based on the attribute of the co, and
• determining, according to the viewer position, transformation information used to correct the image such that a distortion in the image appears reduced to the viewer when the viewer views the image displayed at the display position on the screen,
• the distortion correction processor rendering a correction image that is an image obtained by correcting the image using the transformation information to generate correction-image rendering data that is output to the screen, wherein the image of the content displayed on the screen is viewable from plural seats.

A display system, comprising:

• a display apparatus that displays an image of content on a screen;
• and
• a display control apparatus that includes a distortion correction selecting circuit configured to:
• determine a display position that is a position, on the screen, at which the image of the content is displayed,
• determine a viewer position that is a position of a viewer who views the image, wherein the viewer position is determined based on a display mode indicating a priority between plural seats, the plural seats including a driver's seat and a passenger seat, wherein, when the display mode indicates an equality mode between the driver's seat and the passenger seat, the viewer position is determined as a virtual intermediate position between the driver's seat and the passenger seat, and
• determine, according to the viewer position, transformation information used to correct the image such that a distortion in the image appears reduced to the viewer when the viewer views the image displayed at the display position on the screen, and
• a distortion correction processor configured to render a correction image that is an image obtained by correcting the image using the transformation information to generate correction-image rendering data that is output to the display apparatus, wherein the image of the content displayed on the screen is viewable from plural seats.
