Electronic mirror system
There is provided an electronic mirror system including: a measuring section that a measures a brightness of a vehicle exterior; an imaging section that captures images of rear lateral sides of a vehicle; a display section; an operation section; and a display control section that, in a case in which the brightness measured by the measuring section is less than or equal to a set threshold value, and the vehicle is operated by the operation section so as to travel rearward, switches the imaging range of the imaging section to the second imaging range, and makes a luminous intensity of a dark portion, which is a portion within the display surface of an image displayed on the display surface and whose luminous intensity is lower than a set luminous intensity, be higher than a luminous intensity of the dark portion before the vehicle travels rearward.
1. An electronic mirror system comprising:
a measuring section that measures a brightness of a vehicle exterior;
an imaging section that is configured to switch an imaging range thereof, between a first imaging range and a second imaging range that is wider than the first imaging range, and that captures images of rear lateral sides of a vehicle;
a display section that displays, on a display surface, an image captured by the imaging section;
an operation section that can operate the vehicle so as to advance forward or travel rearward; and
a display control section that, in a case in which the brightness measured by the measuring section is less than or equal to a set threshold value, and the vehicle is operated by the operation section so as to travel rearward, switches the imaging range of the imaging section to the second imaging range, and makes a luminous intensity of a dark portion, which is a portion within the display surface of an image displayed on the display surface and whose luminous intensity is lower than a set luminous intensity, be higher than a luminous intensity of the dark portion before the vehicle travels rearward
wherein,
in a case in which the brightness measured by the measuring section is less than or equal to the set threshold value, and the vehicle is operated by the operation section so as to travel rearward, the display control section makes a light sensitivity of a light receiving portion that corresponds to the dark portion at the imaging section be higher than a light sensitivity of the light receiving portion that corresponds to the dark portion before the vehicle travels rearward, and
in a case in which the brightness measured by the measuring section is less than or equal to the threshold value, and the vehicle is operated by the operation section so as to not travel rearward, the display control section makes the light sensitivity of the light receiving portion that corresponds to the dark portion at the imaging section be higher than the light sensitivity of the light receiving portion that corresponds to the dark portion when the brightness is more than the threshold value.
2. The electronic mirror system of claim 1 , wherein, in a case in which the brightness measured by the measuring section is less than or equal to the set threshold value, and the vehicle is operated by the operation section so as to travel rearward, the display control section corrects information of a first luminous intensity of the dark portion before the vehicle travels rearward, to information of a second luminous intensity of the dark portion such that the second luminous intensity becomes higher than the first luminous intensity, and thereafter, outputs corrected information to the display section.
3. The electronic mirror system of claim 1 , wherein, in a case that is at least one of a case in which the brightness measured by the measuring section is greater than the set threshold value or a case in which the vehicle is operated by the operation section so as to travel in a direction other than rearward, the display control section carries out control so as to make the imaging range of the imaging section be the first imaging range and such that luminous intensity of the image displayed on the display surface is maintained as is.
4. The electronic mirror system of claim 1 , wherein the measuring section measures the brightness based on an average value of amounts of light incident from outside the vehicle.
5. An electronic mirror system comprising:
an illuminance meter that measures a brightness of a vehicle exterior;
a camera that captures images of a rear lateral side of a vehicle, wherein the camera includes a light sensitivity portion;
a display that displays, on a display surface, an image captured by the camera;
a shift that can operate the vehicle so as to advance forward or travel rearward; and
an electronic control unit (ECU) including a processor programmed to:
switch an imaging range of the image captured by the camera, between a first imaging range and a second imaging range that is wider than the first imaging range,
in a case in which the brightness is more than a set threshold value, set a light sensitivity of the light receiving portion of the camera, which corresponds to a dark portion of the image, to a first value, wherein the dark portion is a portion of the image displayed on the display surface whose luminous intensity is lower than a set luminous intensity,
in a case in which the brightness is less than or equal to the set threshold value: determine whether the vehicle is operated so as to travel rearward, and
(i) in a case in which the vehicle is operated so as not to travel rearward, set the light sensitivity of the light receiving portion of the camera, which corresponds to the dark portion of the image, to a second value that is higher than the first value, and
(ii) in a case in which the vehicle is operated so as to travel rearward, switch the imaging range of the image to the second imaging range and set the light sensitivity of the light receiving portion of the camera, which corresponds to the dark portion of the image, to a third value that is higher than the second value.
