In the past, the interior rearview mirror was blocked by the occupants and cargo of the vehicle, but the electronic interior rearview mirror displays the image of the camera device installed at the rear of the vehicle on the display inside the interior rearview mirror. Therefore, it is easy to ensure the rear view
[0003] In general, it is difficult to mount an imaging device on a vehicle without any installation error. Due to the installation error of the imaging device, the image captured by the imaging device may be rotated and the image in the desired direction may not be captured.

Embodiment 1
[0044]
[0045] In the electronic interior mirror of this embodiment, when the driver corrects the installation error of the imaging device 11 , "processing of moving the CMS area in the vertical direction or horizontal direction on the image after rotation correction" is performed. The CMS area is a display area on a display in image data.
[0046] figure 2 It is a figure explaining the position adjustment of the CMS area 8 in the electronic interior mirror of this embodiment. figure 2 (a-1) and figure 1 Same as (b-1) of , showing image data in a state where rotation correction has been performed, figure 2 (a-2) and figure 1 The same as (b-2) of (b-2), showing the CMS region 8 in the state where the rotation correction has been performed. In this state, when the driver moves the CMS area 8 up, down, left, and right, the electronic interior mirror 10 moves the CMS area 8 up, down, or horizontally with respect to the rotation-corrected image.
[0047] figure 2 (b-1)...
Embodiment 2
[0110] In Embodiment 1, the movement of the CMS area 8 in the vertical direction or the horizontal direction after the rotation of the image data is described, but in this embodiment, the movement of the image data in the vertical direction or the horizontal direction of the CMS area 8 is described. Rotate for illustration.
[0111]
[0112] Figure 9 It is a figure explaining the problem of the rotation of the image data after the movement of the CMS area 8 in the up-down direction or the horizontal direction. Such as Figure 9 As shown in (a-1), the imaging device 11 installed at the rear of the vehicle rotates clockwise due to an installation error, so as shown in Figure 9 As shown in (a-2), the image data of the CMS area displayed on the electronic interior mirror 10 is also tilted.
[0113] However, the driver moves the CMS area 8 in the vertical direction or in the horizontal direction before leaning. Figure 9 (b-1) is an example of an image in which the CMS area...
Embodiment 3
[0146] In this embodiment, the electronic interior mirror 10 to which any image processing in Embodiment 1 and Embodiment 2 can be applied will be described.
[0147] Depending on whether the CMS area 8 is moved in the state where the image data has been rotated (Example 1) and whether the image data is rotated (Example 2) in a state where the center of the image data does not coincide with the center of the CMS area 8 (Example 2), it is Can.
[0148] Figure 13 It is an example of a flowchart showing the procedure for selecting a display method of CMS area image data.
[0149] First, the operation accepting unit 22 determines whether or not an image rotation operation has been accepted (S210). If the determination in step S210 is negative, the process proceeds to step S250.
[0150] When the determination in step S210 is YES, the image rotation and movement unit 23 rotates the image data (S220). That is, the rotation of the image data may be directly reflected in either o...

Abstract
Provided is an image display apparatus that readily adjusts a display area to a desired position. An image display apparatus 10 is provided that includes an imaging device 11 configured to generate image data; a receiving means 22 configured to receive movement of a display area in a vertical direction or in a horizontal direction within the image data, the display area being displayed on a display device, and also receive rotation of the image data; an image processing means 23 configured to rotate the image data in accordance with an amount of rotation, and, in a case where the movement of the display area in the vertical direction or in the horizontal direction is received with respect to the rotated image data, move the display area in the vertical direction or in the horizontal direction within the rotated image data; an image cutting means 24 configured to cut the display area from the image data; and an outputting means 25 configured to display the display area on the display device.
Description
technical field [0001] The present invention relates to an image display device and an image display method. Background technique [0002] There are attempts to replace a vehicle's interior rearview mirror with a CMS (Camera Monitoring System). CMS is a technology for displaying images captured by an imaging device on a display. Hereinafter, the interior mirror using the CMS will be referred to as an electronic interior mirror. The electronic interior mirror is a system in which a display is built into a conventional interior mirror. In the past, the interior rearview mirror was blocked by the occupants and cargo of the vehicle, but the electronic interior rearview mirror displays the image of the camera device installed at the rear of the vehicle on the display inside the interior rearview mirror. Therefore, it is easy to secure rear visibility. [0003] In general, it is difficult to mount an imaging device on a vehicle without any installation error. Due to the instal...
