Control apparatus, control method, storage medium, and movable apparatus, with setting transmittance in accordance with display region of virtual image

A control apparatus that is mounted on a movable apparatus and that is configured to control a display apparatus which displays a virtual image to an operator of the movable apparatus, the control apparatus comprising:

• at least one processor or circuit configured to function as:
• (1) a display control unit configured to control the display apparatus so as to display content that is recorded in a recording unit;
• (2) a setting unit configured to set a display mode of the content;
• (3) an attention region setting unit configured to set an attention region within the field of view of the operator of the movable apparatus to which the operator of the movable apparatus should pay attention;
• (4) an attention region data acquisition unit configured to acquire attention region data that indicates a range of the attention region;
• and
• (5) a display region data acquisition unit configured to acquire display region data that shows a range of a display region in which a virtual image is displayed by the display apparatus,
• wherein the setting unit is configured to set transmittance such that, in a case in which the display region of the virtual image is equal to or greater than a predetermined area, the transmittance of the virtual image becomes larger than in a case in which the display region of the virtual image is less than the predetermined area,
• wherein the setting unit is configured to control the display apparatus so as to control the display mode of the virtual image according to (1) a region in the field of view that corresponds to a portion of the display region that overlaps the attention region and (2) a region in the field of view that corresponds to the attention region, and
• wherein, in a case in which the speed of the movable apparatus is less than a predetermined speed, the attention region setting unit is configured to set a second region that captures a portion within the field of view of the operator of the movable apparatus at a distance from the movable apparatus that is less than a predetermined second distance as the attention region.

A control apparatus that is mounted on a movable apparatus and that is configured to control a display apparatus which displays a virtual image to an operator of the movable apparatus, the control apparatus comprising:

• wherein the setting unit is configured to control the display apparatus so as to control the display mode of the virtual image according to (1) a region in the field of view that corresponds to a portion of the display region that overlaps the attention region and (2) a region in the field of view that corresponds to the attention region,
• wherein the setting unit is configured to control the display apparatus so as to change at least the transmittance, the hue, the brightness, or the color saturation of at least a part of the virtual image, or to change at least one element that configures the virtual image, and
• wherein the setting unit is configured to control the display apparatus such that the transmittance of the outline of the virtual image becomes lower than the transmittance inside the outline of the virtual image.

A control method for controlling a display apparatus configured to display a virtual image to an operator of a movable apparatus, the control method comprising:

• display controlling that controls the display apparatus so as to display content recorded in a recording unit;
• setting that sets a display mode of the content;
• setting that sets an attention region within the field of view of the operator of the movable apparatus to which the operator of the movable apparatus should pay attention;
• acquiring that acquires attention region data that indicates a range of the attention region;
• and
• acquiring that acquires display region data that shows a range of a display region in which a virtual image is displayed by the display apparatus,
• wherein in the setting the display mode, the transmittance is set such that, in a case in which the display region of the virtual image is equal to or greater than a predetermined area, the transmittance of the virtual image becomes larger than in a case in which the display region of the virtual image is less than the predetermined area,
• wherein in the setting the display mode, the display mode of the virtual image is controlled according to (1) a region in the field of view that corresponds to a portion of the display region that overlaps the attention region and (2) a region in the field of view that corresponds to the attention region,
• wherein in the setting the display mode, the display apparatus is controlled so as to change at least the transmittance, the hue, the brightness, or the color saturation of at least a part of the virtual image, or to change at least one element that configures the virtual image, and
• wherein in the setting the display mode, the display apparatus is controlled such that the transmittance of the outline of the virtual image becomes lower than the transmittance inside the outline of the virtual image.
