Title: Motion detector
Inventor: MORI YUKIO
IPC: H04N5/232
Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To prevent a place, only brightness of which is changed, from being mis-detected as presence of a motion resulting from motion detection by not outputting the result of motion detection when a difference of average luminance between images is a prescribed value or over. SOLUTION: A motion detection circuit 2 receives a luminance signal of a current field and the luminance signal of the preceding filed that is an output of an FIFO 1 and detects a motion depending on a difference between levels of the luminance signals. An integration circuit 5 receives the luminance signal to calculate the average luminance level for one field. Two-stages of D-FFs 6, 7 sequentially store the average luminance level by field. A |difference| circuit 8 calculates an absolute value of the difference between the average luminance levels of adjacent fields and provides an output.  However, in the case that brightness of a video image is changed between two adjacent fields used for the motion detection, that is, when the |difference|circuit 8 outputs the prescribed level or over to an output buffer 4, the buffer 4 provides the output of no motion information or of preceding motion information.

Filed: 1989-08-31
Abstract: PURPOSE:To quickly select an aimed musical piece by setting a mechanical part in an introduction scanning mode after jumping information recorded on a recording medium by the number of operating times of an introduction scanning key by means of a control part. CONSTITUTION:When the introduction scanning key of the operation part 1 is operated, the control part 7 sets the mechanical part 5 in the introduction scanning mode and the value (n) of an incorporated memory is set as two, then it decides whether the interval between the musical pieces is detected based on the output of a magnetic head 5a.

Abstract: PURPOSE:To record only the distance range required for observation and to reduce the capacity of memory by receiving laser pulse light while combining the coarse counting for useless time for recording using coarse clocks and the precise counting for fine, precise recording time. CONSTITUTION:Clocks from an oscillator 20, which are obtained by dividing the frequency with a coarse frequency divider 21, are counted with a coarse counter 22.

When the counted value C is larger than the value D of the data 23, the counted value E of a precise counter 26 is compared with the value F of precise measured-distance- width data 27, which are inputted beforehand, in a comparator 28. The logical OR of the output of the comparator 24 and the clock output of a fine frequency divider 13 is inputted into the precise counter 26. When the counted value E is smaller than the value F of the data 27, the output of the comparator 28 and the output from an AND gate 25 are counted with a precise counter 30 through an AND gate 29. Thus, the distance data are stored in a memory 10 as the address.
