Abstract

PROBLEM TO BE SOLVED: To solve problems in which screen setting is troublesome or a viewer does not even know there is such the screen setting in order to improve an image by view angle correction such as increasing or reducing luminance, or gamma correction in the screen setting, in a case in which a whole screen is white or black when the screen is viewed in positions of a viewer's eyes shifted above or below from the front surface of a bathroom television device.SOLUTION: A bathroom liquid crystal television device comprises a camera for imaging a face of a viewer and face recognition means for recognizing the face of the viewer from the image imaged by the camera, acquires a relative position between a face position recognized by the face recognition means and a liquid crystal display part, and is made to perform view angle correction of the liquid crystal display part according to the relative position.

Description

  The present invention relates to a bathroom liquid crystal television set used by being fixed to a wall surface of a bathroom.

  There has long been a need to watch television while taking a bath in the bathroom, and many television devices for bathrooms that watch television images in the bathroom have been invented since the days of CRT television devices. In recent years, a liquid crystal display unit has been used instead of a cathode ray tube, and the housing of the television device itself has become a waterproof structure so that it can be directly attached to the wall surface of a bathroom.

  However, the viewing angle of the liquid crystal display unit is limited due to its structure. When viewing the LCD display unit from the front, there is no problem, but when viewing from one side in the up-down direction, the screen turns white as a whole, and when viewing from the other side, the screen is reversed. There is a characteristic of becoming black (see, for example, Patent Document 1).

JP 2008-281622 A (paragraph 0005)

  A remote control that controls the operation of the hot water supply device is attached to the wall surface of the bathroom, and it is necessary to avoid the remote control when installing the bathroom TV later. May not be obtained. Moreover, even if it can be attached to a predetermined position, the height of the eyes rises and falls by changing the posture of the bather to appreciate.

  Since the bathroom TV device is fixed to the wall, the elevation angle of the screen cannot be freely changed. Therefore, when the screen is viewed at a position where the eyes are vertically shifted from the front of the liquid crystal display unit, the entire screen is as described above. It may become white or black.

  In such a case, the image can be improved by adjusting the viewing angle by increasing or decreasing the brightness in the screen settings or by performing gamma correction. However, since such screen settings are not usually performed frequently, In many cases, the user is not only aware that the screen setting operation is troublesome but also capable of such screen setting. For this reason, when the screen is white or black as described above, the patient continues to enjoy watching television images.

  In view of the above problems, an object of the present invention is to provide a bathroom liquid crystal television device capable of automatically performing viewing angle correction.

  In order to solve the above-mentioned problems, a liquid crystal television apparatus for bathroom according to the present invention includes a liquid crystal display unit, and a viewer who watches a television image displayed on the liquid crystal display unit in a bathroom liquid crystal television fixed to the wall surface of the bathroom. A face recognizing unit for recognizing the face of the viewer from the image captured by the camera, a relative position between the face recognized by the face recognizing unit and the liquid crystal display unit. And a viewing angle correction unit that corrects the viewing angle of the liquid crystal display unit according to the relative position.

  In order to perform viewing angle correction, it is necessary to know the relative positional relationship between the liquid crystal display unit and the face of the viewer. Therefore, the face of the viewer is recognized from the captured image of the camera and the position of the face is obtained.

  In music programs and the like, it is not always necessary to continue to view images on the liquid crystal display unit, and there are cases where the eyes are closed and the sound is viewed. In such a case, since it is not necessary to continue displaying an image on the liquid crystal display unit, the face recognition means detects whether or not the viewer's eyes are open, and the time during which the eyes are closed continues for a predetermined time. Then, the display of the television image on the liquid crystal display unit may be stopped.

  As is apparent from the above description, the present invention detects the position of the viewer's face, so that appropriate viewing angle correction can be performed according to the position of the face.

  Reference numeral 1 denotes a bathroom liquid crystal television set (hereinafter referred to as a television set) according to the present invention, which is fixed to a wall surface BW of the bathroom. RC is a remote controller of the hot water supply device, and is usually fixed at the vertical position of the television device 1. When viewing the image of the television device 1, it is often the case that the user views the image while taking a bath in the bathtub BT. Note that there is an infrared remote controller not shown in FIG. 1, and normal operation of the television apparatus 1 is performed by the remote controller.

  The mounting position of the television apparatus 1 may be inevitably changed depending on the mounting position of the remote controller RC for the hot water supply apparatus, and in that case, the TV apparatus 1 may be mounted at a position displaced vertically from the ideal position. In addition, the relative position between the TV device 1 and the viewer's eyes may change due to the size or posture of the viewer taking a bath in the bath BT, and the viewer cannot view the TV device 1 from the front. In some cases, it may be necessary to perform viewing angle correction.

  Referring to FIG. 2, the television device 1 is provided with a display unit 11 by a liquid crystal display unit in the front center. A camera 2 is provided above the display unit 11. The camera 2 is set so as to continue to capture images while the television apparatus 1 is in operation.

  As described above, since the display unit 11 uses a liquid crystal display unit, when viewed from above, for example, when viewed from above, the contrast of the image is lost and the image becomes white as a whole. On the other hand, if the user looks up from below, the image will be entirely black and the image cannot be identified. In such a case, if the viewing angle correction such as gamma correction is performed, the visibility of the displayed image is improved. In order to perform the viewing angle correction, the display unit 11 and the position of the viewer's face You must know the relative position of

  Therefore, the face of the viewer is recognized from the image captured by the camera 2. Referring to FIG. 3, FL is a frame of the captured camera image, and if viewer P is captured in the frame FL, it recognizes the face F of viewer P and recognizes it as the recognized face F. Frame 3 is set. Subsequently, the position of the recognition frame 3 is obtained, and the degree of the viewing angle correction is determined from the vertical position. When the degree of viewing angle correction is determined, a control device (not shown) built in the television device 1 performs viewing angle correction on the display image of the display unit 11.

  By the way, when recognizing the face F, the eyes E of the face F are simultaneously identified and an image is displayed on the display unit 11 in a state where the eyes E are open. When the closed state is maintained for a period of time (about 10 seconds), image display on the display unit 11 is stopped to reduce power consumption.

  Further, when the closed state of the eyes continues for about 10 minutes, the TV device 1 causes the viewer P to make a sound of calling and if the eyes E still do not open, the notification sound is output from the speaker outside the bathroom outside the bathroom. May be configured to flow.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
