Abstract: A method for controlling a television equipped with a camera sensor is performed as follows. A background image is captured by the camera sensor. After entering a control mode, functional blocks are displayed on the television, and a user image is captured by the camera sensor and shown on the television. A control command is based on the user image, the functional block and the background image, and the television is controlled by the control command. Accordingly, the control functions of the traditional remote controller can be replaced by analysis and comparison of the user image and the background image, and therefore, it is more convenient for the user if the remote controller is absent.

Abstract: For changing setting of caption output format, a TV receiver sequentially outputs, to a monitor; a font setting image having options of two parameters, font type and size, in matrix; a color setting image having options of foreground and background colors in matrix; an edge setting image having options of edge type and color in matrix; and an opacity setting image having options of foreground and background opacities in matrix, and allows user to select the options of each two parameters based on each setting image, and further changes the setting image to be output to the monitor, depending on whether “Transparent” is selected as the foreground and/or background color. The TV receiver excludes, from each setting image, an option combination of two options, one causing loss of discriminability of the other, to make impossible selection of such option combination. The user can quickly complete intended setting without redundant procedures.
