Title: Body detecting device
Inventor: NAKANISHI SHOICHI
IPC: G01S17/02
Filed: 1988-03-11
Abstract: PURPOSE:To perform detecting operation without being affected by a light signal by varying the frequency band of a filter and the output frequency of a projector automatically when the quantity of photodetection increases and exceeds a criterion. CONSTITUTION:When the quantity of photodetection exceeds the criterion, the output frequency of a photodetection part 24 is compared with the output frequency of a projection part 21 so as to confirm whether or not said phenomenon is caused by other light frequency signals. Then when both frequencies are nearly equal, the current frequency band of the filter 26 is varied into a frequency band which does not overlap with the current frequency band and the output frequency of the projection part 21 is varied to a frequency in the varied frequency band of the filter 26. Therefore, a photodetection signal by another light frequency signal is cut off by the filter 26 and only the photodetection signal by the reflected light of infrared rays from the projection part 21 passes through the filter 26, thereby deciding whether or not there is a body according to the photodetection signal.

Title: Method for converting picture signal and recording/ reproducing device
Inventor: HIGURE SEIJI
IPC: H04N9/804
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain a picture signal conversion method capable of simply converting correspondence relation between the sampling points of a luminance signal and that of a chrominance signal. SOLUTION: Sampling points (void circles drawn by broken lines) on virtual lines are formed by rearranging the sampling points C00, C01, C02, C03,... and C10, C11, C12, C13,... of chrominance signals corresponding to two adjacent lines in a frame or a field like shown arrows. The number of sampling points per line becomes 2/n the number of sampling points of a luminance signal and a chrominance signal on the virtual line is converted into chrominance signals corresponding to the luminance signals of two adjacent lines in the frame or the field. Consequently a picture signal of a 4:1:1 system e.g. is converted into a picture signal of a 4:2:0 system.
