Title: Variable directivity microphone
Inventor: ISHIGAKI YUKINOBU
IPC: H04R1/38
Filed: 1979-09-11
Abstract: PURPOSE:To realize a setting of the compensating degree to a small value for an equalizer, by securing a phase inversion for the high-range frequency siganl of at least one unit of the microphone and then adding the low-range frequency signal to the output of another microphone with no phase inversion. CONSTITUTION:The output from the microphone 2a receives a phase shift through the phase-shift circuit 6 and then mixed up with the output from the microphone 2b through the mixer 7 and in the same phase. The phase property of the circuit 6 is set so that a phase shift may be secured in the direction of -180 deg. with the frequency axis to which the ratio omega/omegaa is larger than 1 between the angle frequency omega and the angle frequency omegaa with a phase delay of 90 deg. and in the direction of 0 deg. with the frequency axis to which the omega/omegaa is smaller than 1 respectively. As a result, the output of the microphone 2a receives a phase rotation of 180 deg. with the high-range frequency to be mixed up with the output of the microphone 2b. On the other hand, the output of 2a receives no phase rotation with the low-range frequency to be also mixed up with the output of 2b. In this way, the level loss can be avoided with the low-range frequency in particular, thus enabling use of an equalizer having a small degree of compensation.

Title: Video signal processor

IPC: H04N5/06
Filed: 1985-05-29
Abstract: PURPOSE:To make always a horizontal synchronous signal coincident with timing signal groups by forming two timing signal groups relating to horizontal and vertical scanning cycles and resetting counting means of the timing signal groups through a discontinuous-time horizontal synchronous signal of a video signal. CONSTITUTION:A recording signal processing circuit 2 allows video signals inputted from a terminal 1 to assume a signal from to be suitable for recording and a field of the video signals is recorded on a magnetic sheet 5 by a head 4. On the other hand, in case of regenerating, the video signals picked up by the head 4 are brought back to the initial signal form by a regeneration signal processing circuit 6 and are outputted from a terminal 8 after adding a synchronous signal obtained by a compound decoder 21. A system controller 12 permits a reset gate 19 to open for a horizontal scanning period and the reset gate 20 for a vertical scanning period, just after a discontinuity takes place in the video signals. Thus a timing of the timing signal groups outputted by the compound decoder 21 is accurately coincident with the horizontal synchronous signal and its signal processing is always performed smoothly.

Abstract: PROBLEM TO BE SOLVED: To fast and accurately detect or trace the face of a person based on a color picture by deciding as a face of a person at the time of detecting dark areas in a flesh-colored area with a fixed area ratio. SOLUTION: After an A/D converting part 22 converts a full color moving picture that is picked up by an image picking up means 21 into a digital signal, it is sent to a flesh-colored area detecting means 3 of a face detecting and tracing device 1. On the other hand, when the device performs face detection, a color still picture (digital signal) that is picked up by the means 21 is sent as it is to the means 3. Next, a dark area detecting means 4 binarizes luminance (brightness) of Y of an XYZ color system sent from a 1st converting means 31, compares it with a certain threshold and decides it as dark pixels when luminance is below the threshold. A face deciding means 7 decides a flesh- colored area as a human face when black areas are included in the flesh-colored area with an area ratio of a fixed range.

Title: Image forming device
Inventor: NEMOTO EIJI
IPC: G03G21/00
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device for unnecessitating to repeatedly perform an original reading operation, even in the case of making an operational mistake at copying plural sheets. SOLUTION: While the presence of the human body is detected by a human body detecting sensor 505, it is inhibited to erase an operation of erasing image data stored by an image memory, and when the number of sheets to be copied, or a copying mode is changed, a copying processing is performed based on the image data already stored by the image memory. Thus, when the human body stands nearby, the image data read once is held by the image memory. Then, even in the case of making the operational mistake at copying plural sheets and doing over the operation again, the image data read once is read out of the image memory so as to perform the copying processing. An original reading operation is omitted, then, a copying time is shortened.

Abstract: PURPOSE:To correct uneven rotation due to eccentricity of a disc by storing an eccentric data of the disc while the disc is turned at least once, and changing a threshold level obtained from waveform shaping of the output of a rotary detector based on the stored content. CONSTITUTION:An output signal of a waveform shaping circuit 5 and a reference signal are compared by a phase comparator at first via a switch S4 and the result is fed to a DC motor.

Further, a signal recorded on the disc is read and counted by a counter 6 at each region, a microcomputer 7 calculates the data of deflection and the result is latched by a latch circuit 8. In driving the motor while the eccentricity is corrected, the output of the circuit 5 is converted into a triangle wave by a waveform shaping circuit 9, binary-coded by the output of a threshold level generating circuit 11 to control the motor. Thus, uneven rotation is prevented in such a way.
