Abstract: In a VTR reproduction mode, since a signal of which a luminance signal and a chroma signal that have been band-limited are combined is supplied to a Y comb filter (3) and a C comb filter (4), processing can be performed with only one A/D converter (14). In addition, the A/D converter and 2H line delay circuits for processing camera signals can be commonly used in the VTR reproduction mode.

Abstract: PROBLEM TO BE SOLVED: To provide a communication device capable of improving a decline in usability caused by the angle of view of a camera.SOLUTION: In a VC device 1, faces f1, f2 are detected out of captured pictures 3 captured by a camera 1R, to generate a partial picture 4 including the detected faces f1, f2 and afterwards, the partial picture 4 is displayed on a display panel 1H as a video phone picture in the VC device 2 of a counterpart. The angle of view of the camera 1R itself is not adjusted but a picture size correlated with the angle of view of the camera 1R is adjusted by generating the partial picture 4 (segmenting the partial picture from the original picture).

Abstract: PROBLEM TO BE SOLVED: To provide the detection circuit for a signal level in which adjustment of a threshold level of a level detector is not required, the threshold level of he level detector is set easily, and a stable comparison output is obtained from a level comparator, dispite frequent level fluctuations of an output digital level. SOLUTION: This digital signal level detection circuit having a level comparator 45, that compares the level of an input digital signal with a threshold level, is provided with a compression means 32 that compresses a level change width of the input digital signal. The compression means 32 supplies the digital signal to the level comparator 45, where the signal level is compared with the threshold level.

Abstract: PURPOSE: To reduce circuit scale by selectively outputting the output of a luminance signal comb-line filter and a chroma signal comb-line filter or the output of a camera signal processing circuit. CONSTITUTION: The frequency band of a luminance signal Y and a chroma signal C is limited and the component of the signal Y and the component of the signal C are added so as to be separated in terms of frequencies and the added signal is fed to an input terminal 1. Then the added video signal or the image pickup signal picked up by an image pickup element is given to an A/D converter 14, in which the image pickup signal is digitized. An output of the A/D converter 14 is fed to a terminal 22B of a switch circuit 22 and the circuit 22 is thrown to the position of the terminal 22B in the case of the VTR reproduction mode and a switch circuit 23 is thrown to the position of a terminal 23A. Then the output of the A/D converter 14 is fed to a cascade connection circuit of one-line delay circuits 16, 17. Then an output of the circuit 23 and an inter-stage output of the circuits 16, 17 are fed to a Y comb-line filter 3. Furthermore, the output of the circuit 23, the output of the circuit 27 and the inter-stage output of the circuits 16, 17 are fed to a C comb-line filter 4.

Abstract: PROBLEM TO BE SOLVED: To attain evaluation and inspection by selectively giving signal to the multi-function composite integrated circuit and selectively outputting an output signal of a received transmission block from the multi-function composite integrated circuit to utilize a function check substrate for a 1st generation IC or the like. SOLUTION: Selector switches 2-6 to select a signal to be given to function blocks 12-16 are provided V this side of the function blocks 13-16 other than a camera signal processing function block 12 at the head of the function blocks 12-16. Furthermore, an IC 1 is provided with selector switches 7-9 to select signals outputted from its terminals before an input/output bidirectional terminal bpin and output terminals dpin, epin. A control signal to designate a signal to be selected is fed to the switches 2-9. Thus, the IC is handled externally as if to include only one function block.

Abstract: PROBLEM TO BE SOLVED: To conduct a necessary test by using a simple pattern signal. SOLUTION: Parallel data (a to h) from a serial-parallel converting circuit 1 are supplied to a selector 13. Further, this selector 13 is supplied with a switching control signal from a counter 14. Then parallel data from this selector 14 are taken out to the pin output terminal 18 of an integrated circuit device through a selector 15 and a flip-flop(FF) 17. Further, the clock signal from a terminal 19, the reset signal from a terminal 20, and the test control signal from a terminal 21 are supplied to the counter 14. This counter 14 counts the clock signal and its count value is supplied as a switching control signal to the selector 13. Consequently, the parallel data are selected according to the count value and are taken out to the pin output terminal 18. The parallel data are determined and, for example, a converting circuit 1 is tested.

Abstract: PURPOSE: To obtain the magnetic recording and reproducing device in which color drooping is prevented and the S/N is improved. CONSTITUTION: When no crosstalk is included in a chroma signal or its level is equal to or less than a noise level, since a head is seldom bridged over an adjacent track, the level of the crosstalk is less than the noise level. In this case, a switch SW 1 is thrown to the position of a limiter 20 to eliminate a non-correlation component of the chrominance signal. As a result, even when a feedback quantity is increased to improve the S/N, color drooping is not increased and the image quality is enhanced. On the other hand, when the crosstalk is included, since the signal is not given to the limiter 20, the switch SW 1 is thrown to the other position, then an output signal (feedback signal) from a BPF 2 is fed to an ATT 3 as it is.
