Description

  The present invention relates to a projector apparatus that magnifies and projects a television image on a screen, and more particularly to a technique for correcting image distortion of a projected image.

  In recent years, projection televisions (hereinafter abbreviated as projectors), which can project television images on a screen and enjoy large screen images, have attracted attention and increased demand due to the miniaturization of devices and the improvement in brightness. ing. In this projector, since an image is projected in an enlarged manner, image distortion occurs in the projected image on the screen due to distortion of the projection optical system and screen, setting deviation of the projection angle from the projector to the projection screen, and the like. Further, zoom adjustment for enlarging and reducing an image and aspect adjustment for changing the aspect ratio from 4: 3 to 16: 9 or vice versa are also required. For this reason, projectors usually have an image adjustment function for adjusting a projected image when a product is completed or used.

  In the conventional image adjustment function, the menu key of the remote control device (hereinafter abbreviated as “remote control”) is used to select the image adjustment menu and the image is adjusted using the cross key or arrow key in the remote control key. The image was adjusted by selecting the necessary items from the menu adjustment items. However, in such image adjustment, since there are many adjustment elements including vertical and horizontal widths and heights, the distortion position of the image does not always correspond to the remote control key position, so the adjustment work is complicated and the adjustment time Therefore, an adjustment means that is as easy as possible has been desired.

A conventional remote controller for operating a remote control key and an image display screen in correspondence with each other, as shown in FIG. 10, is a remote controller that selects a broadcast channel from divided images on a display unit (see, for example, Patent Document 1). FIG. 11 shows a display unit 201 of a television receiver in which an image display screen is divided into four. In FIG. 10, the remote control device 101 includes a numeric keypad 102 and an up / down key unit 103. A number 1 key 111, a number 2 key 112, a number 4 key 113, and a number 5 key 114 of the numeric keypad 102 are shown in FIG. 11 corresponds to the four divided screens 202, 203, 204, 205 of the display unit 201 of the television receiver 200 shown in FIG. Corresponding to these divided screens, each broadcast channel, for example, CH1, CH12, CH23, CH98 is registered, and the broadcast channel displayed on this divided screen is selected by the remote control key numbers 1, 2, 4, 5. It is. However, this is to select a channel by partially corresponding to the split screen and the remote control display key, not to the image adjustment, and only with the numeric keypad arranged on the remote control operation panel. There is a limit to the arrangement of the adjustment buttons that are easy to understand visually corresponding to the image adjustment positions, and there is a problem that it takes time and effort to adjust the image.

  As shown in FIG. 7A, when the aspect ratio of the screen is switched from 4: 3 to 16: 9 on the projected image plane, the button SW-T2 or / and SW- in the middle of the upper and lower side buttons. The original image A is adjusted using the B2 side button. On the contrary, when the aspect ratio is switched from 16: 9 to 4: 3 as shown in FIG. 7B, the original button SW-L2 and / or SW-R2 in the middle of the left and right side buttons is used. To image A. In addition, for these aspect adjustments, the vertical width or the horizontal width is not only switched by each adjustment button SW-T2 or / and SW-B2, SW-L2, or / and SW-R2, but these switches are stepped. It is possible to finely adjust the vertical and horizontal widths by pressing them down.

  FIG. 8 shows a zoom function for obtaining an image Z2 obtained by enlarging a part Z1 of the image on the projected image plane. Here, when the center button SW-C is turned on, the Z1 portion in the projected image is zoomed in and enlarged, and when the center button SW-C is turned off, the Z2 portion in the projected image is zoomed out and reduced. The

  As shown in FIG. 9, by rotating the switch box 51 from the horizontally long switch box 51X by 90 degrees to the vertically long switch box 51Y, the original horizontally long image X is linked with the rotation of the switch box 51. By rotating the image 90 degrees, a vertically long image Y can be obtained. Further, by rotating the switch box 51 by 180 degrees, the projected image can be rotated by 180 degrees with respect to the original image, and the vertical direction of the image can be switched. Thus, when it is necessary to change the vertical direction of the image, for example, the projector 1 shown in FIG. 1 is turned upside down (with the top plate facing down and the bottom plate facing up). There are cases where it is attached to the ceiling of the room, or when it is desired to show the figure upside down in mathematics classes.
