摘要： PROBLEM TO BE SOLVED: To obtain an image display device capable of deciding the feature estimation of broadcasted contents with not only from an information transmitted from a broadcasting station but also from others and capable of deciding an image at every genre at a real time. SOLUTION: The feature of contents is decided on the basis of a maximum gradation value or a value corresponding to the value, an intermediate gradation value or the value corresponding to the intermediate gradation value, a minimum gradation value or the value corresponding to the minimum gradation value and a mean gradation value or the value corresponding to the mean gradation value obtained from a histogram uniformly dividing the number of gradations in the brightness signal of an input video signal, and the gradations are corrected to an image signal. Consequently, a contrast can be adjusted in response to the characteristics of contents. The contrast can be improved without operating a contrast adjusting function. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PURPOSE: To suppress the adverse effect on an output video signal when the processing for the video signal is switched by the decision result by stably outputting the decision result as to whether the video signal is in conformity with a prescribed system or not. CONSTITUTION: A non-standard detection circuit 8 outputs the detection signal as to whether an input video signal is a standard signal or not, an up and down counter 9 counts a clock and the count direction is set by the detection signal. A switch circuit 5 switches outputs of two-dimensional and three- dimensional processing circuits 3 and 4 based on the decision signal as to whether the input video signal is the standard signal or not (count output Q4). A reset circuit 10 generates a reset signal from the count output Q4 and the count value is reset so that the count value may not remain behind when the decision signal is switched to an 'L' level.

摘要： PURPOSE: To correctly separate a TV signal into luminance and chroma signals despite the sudden change of the TV signal and also to reduce the cross-color or the deterioration of oblique image resolution by providing a 2nd chroma signal extraction means, a vertical non-correlation detection means and a selection means in addition to a 1st chroma signal extraction means. CONSTITUTION: The input signals received through a terminal 1 is delayed by the field delay circuits 4a to 4d and the line delay circuits 3a to 3d via an A/D converter 2 and then inputted to a filter 5. The output signal of the circuit 3b is inputted to a filter 6, and the output signals of the circuits 4b, 3b and 3c are inputted to a correlation detection circuit 7. The outputs of the filters 5 to 7 are inputted to the compensating delay circuits 9a, 9b and 10a, and the outputs of the circuits 9a and 9b are inputted to a switch circuit 11. The circuit 11 selects one of two outputs based on the output signal of the circuit 10a and outputs the selected output as a chroma signal through an output terminal 13. At the same time, the selected output is subtracted from the output of a compensating delay circuit 8 by a subtractor 12. The result of this subtraction is outputted to an output terminal 14 as a luminance signal.

摘要： PURPOSE:To simplify handling during the photographing, by a method wherein an ultrasonic wave receiving section is provided within a wireless microphone carried by a main object and receives a radio wave transmitted from the wireless microphone to measure a distance detecting the presence of an ultrasonic signal. CONSTITUTION:An ultrasonic wave S is transmitted from an ultrasonic wave transmitter 7 of a video camera and collected with an ultrasonic microphone 11 of a wireless microphone 8 carried by a main object to be converted into an ultrasonic signal. A voice near the main object is collected 10 to be converted into a voice signal. After mixed 12 together, these ultrasonic wave signal and voice signal are transmitted 13 as radio wave P. The radio wave P is received 14 and separated 15 into an ultrasonic wave signal Ss and a voice signal Sv. The signal Ss thus separated is checked for the presence thereof with a detector 16 and a detection signal is outputted to a microcomputer (MC)17. A distance measurement signal indicating a distance to the main object is obtained with the MC17 by a computation to move a photographing lens 19 with a lens driving mechanism 18 according to the distance measurement signal thereby adjusting the focus of a video camera on the main object.
