Onboard display device, control method for onboard display device, and control program for onboard display device

An onboard display device comprising:

• a display that includes a display region set on a front passenger seat side of a vehicle width direction center position at a front face side of a vehicle cabin and the entire display region is positioned between the vehicle width direction center position and a vehicle side section of the front passenger seat side, positioned between the vehicle width direction center position and a vehicle side section of the front passenger seat side, and that is capable of displaying a picture in the display region, the display region including a first display region and a second display region disposed at a vehicle width direction inner side of the first display region so as to lie in a row with the first display region, with a non-display region therebetween;
• a first image capture section that is disposed at a vehicle side on the front passenger seat side and that captures images of a vehicle rearward;
• a second image capture section that is disposed at a vehicle rear end, and that captures images of the vehicle rearward in an imaging range partially overlapping with an imaging range of the first image capture section;
• and
• a display controller that converts a second image captured by the second image capture section to a point-of-view-converted image viewed as if from a hypothetical point-of-view at an installation position of the first image capture section, that stitches a first image captured by the first image capture section with an image from a range in the point-of-view-converted image not overlapping with the first image to generate a composite image, that associates an overall region of the composite image with a region combining the first display region, the non-display region, and the second display region, that extracts from the composite image an image region corresponding to the first display region to generate a first trimmed image and extracts from the composite image an image region corresponding to the second display region to generate a second trimmed image, and that controls the display so as to display the first trimmed image in the first display region as the picture and controls the display so as to display the second trimmed image in the second display region as the picture,
• wherein the display region is set such that in vehicle plan view an imaginary straight line passing through an anticipated driver-eye position and a vehicle width direction position corresponding to a terminal position at the vehicle width direction inner side of the front passenger seat at a front end of a vehicle interior ceiling passes through a range extending from a vehicle width direction inner end of a first range where the picture based on the first image is displayed to a vehicle width direction outer end of a second range where the picture based on the second image is displayed.

• the control method comprising:
• converting a second image captured by the second image capture section to a point-of-view-converted image viewed as if from a hypothetical point-of-view at an installation position of the first image capture section, stitching a first image captured by the first image capture section with an image from a range in the point-of-view-converted image not overlapping with the first image to generate a composite image, and using the display to display the composite image in the display region as the picture,
• wherein the display region is set such that in vehicle plan view an imaginary straight line passing through an anticipated driver-eye position and a vehicle width direction position corresponding to a terminal position at the vehicle width direction inner side of the front passenger seat at a front end of a vehicle interior ceiling passes through a range extending from a vehicle width direction inner end of a first range where the picture based on the first image is displayed to a vehicle width direction outer end of a second range where the picture based on the second image is displayed.

• and
• a second image capture section that is disposed at a vehicle rear end, and that captures images of the vehicle rearward in an imaging range partially overlapping with an imaging range of the first image capture section,
• the control method comprising:
• converting a second image captured by the second image capture section to a point-of-view-converted image viewed as if from a hypothetical point-of-view at an installation position of the first image capture section, stitching a first image captured by the first image capture section with an image from a range in the point-of-view-converted image not overlapping with the first image to generate a composite image, associating an overall region of the composite image with a region combining the first display region, the non-display region, and the second display region, extracting from the composite image an image region corresponding to the first display region to generate a first trimmed image and extracting from the composite image an image region corresponding to the second display region to generate a second trimmed image, and using the display to display the first trimmed image in the first display region as the picture and using the display to display the second trimmed image in the second display region as the picture,
• wherein the display region is set such that in vehicle plan view an imaginary straight line passing through an anticipated driver-eye position and a vehicle width direction position corresponding to a terminal position at the vehicle width direction inner side of the front passenger seat at a front end of a vehicle interior ceiling passes through a range extending from a vehicle width direction inner end of a first range where the picture based on the first image is displayed to a vehicle width direction outer end of a second range where the picture based on the second image is displayed.
