Title: Visual axis detector
Inventor: AOYAMA KEISUKE
IPC: G03B13/36
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To achieve a speeding up of the operation of detecting a visual axis without lowering the accuracy thereof by varying the number of optoelectrical transducers composing a block area according to an output of a distance information detection means which detects information pertaining to eye balls of a user, a visual axis detector and a distance. SOLUTION: In a visual axis detection circuit 101, an output of an eye ball image from an image sensor 14 is transmitted to a CPU 100. The CPU 100 performs an A/D conversion of the eye ball image signal to extract feature points of the eye ball image necessary for the detection of a visual axis according to a specified algorithm, further calculates the angle of rotation of the eye balls of a person to be taken from the positions of the feature points and also detects the brightness of the surrounding area by an output of the image sensor 14. An IRED drive circuit 107 works to light IRED-0-7 illuminating the eye balls of the person to be taken by infrared rays.  At this point, information pertaining to the eye balls of the user, a visual axis detector and a distance is detected to vary the number of electrooptical transducers composing one block area of the image sensor 14 according to information on the distance.

Title: Semiconductor device
Inventor: SASAKI KUNIO
IPC: H03K5/13
Filed: 1990-06-27
Abstract: PURPOSE:To prevent malfunction due to fluctuation in a power line due to simultaneous operation of circuit components by delaying the operation of one signal only when 1st and 2nd input signals such as an output control signal and a logic input signal are changed simultaneously. CONSTITUTION:When 1st and 2nd output signals such as an output control signal and a logic input signal are changed, 1st and 2nd edge detection circuits 1a, 1b detect an edge of the signals to generate a prescribed pulse. Moreover, a pulse signal is generated by ANDing or ORing two output signals of the 1st and 2nd edge detection circuits 1a, 1b only when input signals A, B are changed simultaneously. One signal is delayed by a delay circuit 4 for a time width equivalent to the pulse width of the output pulse 7 by ORing or ANDing the output pulse 7 and one signal. Thus, simultaneous changeover of the signals is prevented to prevent malfunction.

Title: Secam signal processing circuit
Inventor: KUSAKA SHUICHI
IPC: H04N9/793
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To eliminate the fluctuation at the rise position of a synchronizing signal in spite of recording and reproducing a SECAM chroma signal and to prevent the generation of the jitter in a TV picture by muting a SECAM chroma signal from an REC equalizer circuit in a period equivalent to a synchronizing signal period. SOLUTION: A pulse expanding circuit 14 impresses a gate pulse to a sink gate circuit 10 and impresses a mute signal to a muting circuit 15. The mute signal is generated in the period equivalent to the synchronizing signal to the SECAM chroma signal from the REC equalizer circuit 11. An advantage is that as the gate pulse and the mute signal use the single signal, the increase of the number of elements is reduced. As a horizontal synchronizing signal has its rise edge utilized in general, the mute signal is timing-set so as to include a rise timing. Consequently, the unnecessary component caused by the sharpness of the circuit 11 is reduced.
