摘要： PROBLEM TO BE SOLVED: To provide a wiring connection inspection device and a wiring connection inspection method, capable of inspecting easily and accurately both the connection state between a plurality of integrated circuits in actual operation and the connection state at the generation time of a mounting failure in the market. SOLUTION: A digital signal and an error detection signal (1), generated based on the digital signal by an operation device (1)102, are outputted from an integrated circuit (1)101, and the signals are inputted into an integrated circuit (2)107 via each board bonding part, from 103 to 108 and from 104 to 109. An error detection signal (2) is generated based on the inputted digital signal by an operation device (2)110 and is compared with the error detection signal (1) by a comparison device 111. When both signals always agree with each other, it is determined that a connection failure between the integrated circuits does not exist, and when a disagreement in timing exists, it is determined that a connection failure exists.

摘要： PROBLEM TO BE SOLVED: To obtain an apparatus for detecting motion vectors for detecting effectively correct motion vectors to be detected effectively, even if the movement of small areas exists in a macroblock in the motion vector detecting apparatus for detecting the motion information of moving pictures.
SOLUTION: The absolute difference between frames is compared with a threshold set beforehand; in frame difference other than the target pixels, by ruling out the absolute value of the difference larger than a given threshold from accumulation of each of small regions, the accumulation of the absolute value of the difference in the direction of the vector originally detected becoming larger than the other incorrect vectors is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a video display device and a video display method capable of displaying the video signals of a unidirectional progressive scanning system or a unidirectional interlace scanning system as video images of high image quality by a bidirectional scanning system. SOLUTION: The video signals of the interlace scanning system of a scanning line number 525 and a vertical scanning frequency 60 Hz are converted to the video signals of the scanning line number 1050 and the vertical scanning frequency 120 Hz and the video images are displayed by bidirectional scanning. By performing the offset processing of 1/4 horizontal scanning period to vertical synchronizing signals at the time of starting an odd-numbered field, the relation of interlace is kept in the odd-numbered field and an even-numbered field. By performing the offset processing of 1/2 horizontal scanning period to the vertical synchronizing signals for each frame, the scanning direction of the respective scanning lines is inverted for each frame.

摘要： PROBLEM TO BE SOLVED: To quickly display the state of a display picture without malfunction at the time of the state change of a monitor scene by providing a motion detection circuit, a picture memory and a control circuit SOLUTION: The monitor scene inputted to an input video signal terminal 1 is inputted to a motion detection circuit 2 and a picture memory 3, and the detection circuit 2 detects whether the monitor scene is changed or not and inputs the detection result to a control circuit 4. The control circuit 4 generates a memory control pulse so that an N-field portion of the signal is stored in the memory after the change of the monitor scene, and the circuit 4 generates a switching control signal of a switch 6 for switching, for example, a video signal inputted to the input terminal and the output of the memory 3 and displays them on a display device 7. The memory 3 is used for the purpose of not only repeatedly displaying data stored in the memory 3 but also freely changing the display picture size. Consequently, display of the monitor scene is possible without using the memory 3, and the memory 3 may be eliminated.
