Abstract: The display control device that causes a display screen to display predetermined image information includes; a display adjustment signal superimposing unit that superimposes a display adjustment signal for adjusting the timing of displaying a pixel in accordance with image information, on a portion of a signal corresponding to a region outside the display screen on a horizontal scanning line; an image signal sampling unit that performs sampling for an image signal in accordance with the image information in predetermined sampling timing; a display control unit that performs display control for the pixel, using a value obtained through the sampling performed by the image signal sampling unit; a display adjustment signal sampling unit that performs sampling for the display adjustment signal in predetermined sampling timing; an optimum display timing detecting unit that detects optimum timing of displaying the pixel by changing the sampling timing in the display adjustment signal sampling unit, based on a value

Abstract: A red light sensor (222D), a green light sensor (232D), and a blue light sensor (242D) are provided on the LCD panel (200) of a display device (100). A processing section (170) of the display device (100) corrects, in an LCD correction control unit (173), a video image display state at positions corresponding to the red light sensor (222D), the green light sensor (232D), and the blue light sensor (242D) in the LCD panel (200) based on a state of outside light detected by the red light sensor (222D), the green light sensor (232D), and the blue light sensor (242D).

Abstract: A display control device is provided that can maintain excellent display for users while the timing of displaying each pixel is being adjusted. A display control method and a display control program are also provided.

Abstract: An image processing apparatus, which displays an image corresponding to a synchronizing frequency change-image signal, which is obtained by changing a frequency of a synchronizing signal of an image signal, and an other image corresponding to an other image signal on a same display screen. The apparatus comprises a monitoring device and a synchronizing control device. The monitoring device monitors temporal relationship between the synchronizing signal of the synchronizing frequency change-image signal and a synchronizing signal of the other image signal. The synchronizing control device performs frequency regulation for the synchronizing frequency change-image signal based on the monitoring results from the monitoring device so as to prevent one of the synchronizing frequency change-image signal and the other image signal from passing the other thereof on the display screen.

Abstract: When an antenna which is favorable in receiving state is selected from among a plurality of antennas by an antenna selector, white noise is caused in a video signal by AGC characteristics of an AGC circuit in a tuner, and displayed on a display screen. A switching control unit exercises luminance altering control for a luminance altering unit on the basis of an output level difference or the like of the AGC circuit, lowers luminance of a white noise generating region only during a white noise generating interval, and thereby makes the white noise inconspicuous.

Abstract: A display control device permits a display screen to display predetermined image information. The display control device comprises: a detecting device which receives a signal having a display adjustment signal superimposed thereon, samples a plurality of portions from the display adjustment signals, and detects optimum timing based on a plurality of sampled values, the display adjustment signal being used for adjusting the timing of display of each pixel of the image information, the display adjustment signal being superimposed upon the signal on a horizontal scanning line in a signal portion corresponding to a region outside the display screen; and an adjusting device which adjusts the timing of display of each pixel in accordance with the detected optimum timing.

Abstract: A transmission prohibition control section 12 prohibits a transmission section 10 from transmitting a communication radio wave in response to a command of the user, etc. When transmitting a communication radio wave is prohibited, a central control section 11 displays the fact that a communication radio wave is prohibited on first and second communication mode display sections 2a and 2b in such a manner that outsiders can also check it. Further, while transmitting a communication radio wave is prohibited, the central control section 11 accepts and executes any other function than a communication function, selected by the user, etc. A preset function of presetting a function to be executed after the prohibition of transmitting a communication radio wave is released is provided.
