In a video display control device, a control data generating section allocates a part of a dynamic range of a high gradation region of a video signal to a low gradation region, and a backlight controlling section controls a light emission luminance of a backlight so as to cancel an increase or decrease of a mean luminance of a video displayed on a screen in accordance with an increase or decrease of the mean luminance of a video signal after correction with respect to a mean luminance of the video signal.

Video-display control device for correcting a video signal and controlling a backlight

An information system capable of utilizing information in which a user evaluation pertaining to the environment or conditions surrounding a traveling vehicle is highly precise (very near real time). The information system () comprises an onboard terminal device () for outputting information obtained by a user's input operation, a communication terminal device () for transmitting the information outputted by the onboard terminal device () to the exterior, and an information center () for classifying and delivering the information received from the onboard terminal device (). The onboard terminal device () varies the level of detail of the information that the user is allowed to input in accordance with the speed of the vehicle or the presence/absence of a passenger other than the driver of the vehicle.

A video display control device includes a video signal processing section that corrects a video signal and outputs a video signal after correction to a display, and a backlight controlling section that controls a light emission amount of a backlight. A control data generating section allocates to a low gradation region of the video signal a high gradation region dynamic range of the video signal in which a video signal corresponding to a black band region is excluded. The backlight controlling section controls a light emission luminance of the backlight so as to cancel out an increase or a decrease in the mean luminance of the video displayed on a screen.

A flexible cable is provided in which a transmission characteristic can be ensured in a high frequency band, and electromagnetic noises can be suppressed. A flexible cableincludes a sheet-like base member (dielectric substance); an adhesive (dielectric substance)which bonds the base memberto a cover member (dielectric substance); a shield memberwhich covers the cover memberand is bonded or printed to the cover memberto suppress electromagnetic noises to be radiated; and a top coating memberwhich covers the shield memberto protect the shield member. The flexible cablehas a differential signal wire groupincluding differential signal wiresthrough which differential signals pass and guard ground wireswhich prevent the interference from other differential signals; a low-speed signal wirethrough which a low-speed signal passes; a ground wireused as a ground; and a shield ground wirewhich is adapted to allow the electric potential of the shield memberto be identical to the electric potential of the ground, all of which are provided in the adhesive. The differential signal wiresare not covered with the shield member

The object is to provide a video signal processing apparatus capable of minimizing overtaking of fields of a video signal and continuous display of the video signal of the same field and reducing degradation in image quality of the output video signal. The apparatus has a field signal holding sectionwhich holds the value of an input field signal and outputs the held value as a held value signal and a readout determination sectionwhich determines the video signal of the field to be read out, and which outputs the determined signal as a readout field signal. The field signal holding sectionholds the value of the input field signal a plurality of times with every occurrence of the readout field signal period, and outputs a held value signal constituted of the plurality of values of the input field signal held. The readout determination sectiondetermines the video signal of the field to be read out from a frame memoryon the basis of the value of the held value signal in the current readout field period and the value of the held value signal in the immediately preceding readout field period.
