Abstract: In a display apparatus, a luminance acquiring unit acquires luminance signals from inputted image signals. A difference calculating unit compares luminance signals of the current frame acquired by the luminance acquiring unit with those of a previous frame stored in a frame memory, and then takes a difference between these luminance signals. If the difference of the luminance is large, a judging unit judges that the image corresponding to a portion in question is moving. If the difference of the luminance is small, the judging unit judges that the image corresponding to the portion stays still. A gain calculating unit gradually lowers the luminance corresponding to a part where the image stays still, and gradually restores to the original level the luminance corresponding to a part where the image is moving.

Abstract: An apparatus and method to estimate the condition amount of a vehicle tire in a vehicle equipped with vehicle wheels formed with air enclosed under pressure in an inside portion of a tire mounted to a disc wheel. A plurality of wheel speed sensors detect the vehicle speed of each vehicle wheel. An estimating unit obtains a reflected value reflecting the tire condition amount of a vehicle wheel based on the vehicle wheel speed, and estimates the tire condition based upon the reflected value. The estimating unit estimates a reflected value for a first vehicle wheel which is difficult to accurately obtain the reflected value based on the vehicle wheel speed by obtaining the reflected value for a second vehicle wheel which is easier to accurately obtain the reflected value based on the wheel speed.

Abstract: The present invention provides a method and apparatus for estimating a state of tire air pressure with high accuracy in a range of vehicle speeds from a low travel speed to a high travel speed. A wheel speed of each of a right-hand front wheel and a right-hand rear wheel is detected based on wheel speed signals outputted from vehicle speed sensors, and characteristic amounts (power) of frequency characteristics of the wheel speeds are calculated. A value of difference which represents a degree of difference between the obtained characteristic amounts of the right-hand front wheel and the right-hand rear wheel is calculated. Based on the value of difference, the state of air pressure of a tire is determined. As a result, it can be determined if the air pressure of one of tires on the right-hand front wheel and the right-hand rear wheel has been reduced.

Abstract: A variable value (dynamic load radial deviation &bgr;) for making determination of a tire air pressure is calculated from pulse number cumulative values PFL, PFR, PRL and PRR that are cumulated for individual wheels when a predetermined condition is fulfilled. The calculated variable value is stored as a reference variable value, and a speed of a vehicle at the time when the reference variable value is calculated is stored as a reference vehicle speed associated with the reference variable value. If the value is newly calculated, it is determined whether or not a vehicle speed at that moment is within a predetermined vehicle speed range determined by the reference vehicle speed. If it is determined that the vehicle speed is within the predetermined vehicle speed range, it is determined, based on a difference between the newly calculated variable value and the reference variable value associated with the reference vehicle speed, whether or not the tire air pressure is normal.
