According to embodiments, a synchronization signal generating device includes: a cycle measuring unit configured to measure the vertical synchronization interval of the input video signal; a phase difference detecting unit configured to detect a phase difference between an input vertical synchronization signal based on the input video signal and the display vertical synchronization signal; and a vertical cycle determining unit configured to determine a cycle of the display vertical synchronization signal based on a measurement result of the cycle measuring unit and a detection result of the phase difference detecting unit so that the phase difference is decreased within the range of the compensation interval, and to determine 1/n of the cycle of the display vertical synchronization signal as a cycle of an n-times speed vertical synchronization signal.

Synchronization signal generating device and display apparatus

A synchronization signal control circuit according to embodiments includes a phase difference detecting section and a vertical synchronization correction control section. When a vertical synchronization period of an input video signal is within a compensation period range between a minimum vertical synchronization period and a maximum vertical synchronization period, the synchronization signal control circuit outputs a display vertical synchronization signal used for displaying the input video signal to a display section capable of providing a display based on the input video signal. The phase difference detecting section detects a phase difference between an input vertical synchronization signal based on the input video signal and the display vertical synchronization signal. The vertical synchronization correction control section corrects the cycle period of the display vertical synchronization signal within the compensation period range so as to reduce the phase difference.

Synchronization signal control circuit and display apparatus

A video signal synchronization signal generating apparatus for making a display reference synchronization signal Vb that serves as a reference of video display and has a first frequency and an input synchronization signal Vi that constitutes images and has a second frequency synchronized with each other, the apparatus including: a frequency ratio generating section configured to divide a frequency that is double the first frequency by the second frequency to calculate a frequency ratio n; a Vx generation comparator circuit section configured to generate coincidence signal Vx' having pulses that are inserted by equally dividing one period of the input synchronization signal Vi by the frequency ratio n; and a Vx generation circuit section configured to remove the alternate pulses of the coincidence signal Vx&#x2032; to generate synchronization signal Vx of a same phase as the phase of the input synchronization signal Vi.

Video signal synchronization signal generating apparatus and video signal synchronization signal generation method

A synchronizing signal control circuit includes: a phase detecting section configured to detect a phase difference between a display synchronizing signal and an input synchronizing signal; an adding section configured to add a set value for setting a synchronization compensation period and the detected phase difference; a synchronization phase correcting section configured to correct the phase of the input synchronizing signal on the basis of the output signal of the adding section; a gate signal generating section configured to generate a gate signal representing the synchronization compensation period based on the display synchronizing signal; a synchronization determining section configured to determine whether the synchronization can be effected, by detecting whether the input synchronizing signal exists within the synchronization compensation period; and a selecting section configured to perform switching to the corrected input synchronizing signal on the basis of the determination result of the synchronization determining section.

Synchronizing signal control circuit and synchronizing signal control method

A video-signal processor includes: a first correlation detector obtaining a correlation value of every symmetric pair of pixels positioned in point-symmetry around an interpolation pixel on an interpolation line interpolated between two real lines; a second correlation detector obtaining a correlation value of every pair of pixels for the symmetric pair of pixels and parallel pair(s) of pixels positioned in a direction parallel to a direction of the symmetric pair of pixels; a correlation-direction deciding unit deciding one of a correlation direction based on the correlation value from the first correlation detector and that based on the correlation value from the second correlation detector as a correlation direction which is a direction of the pair of pixels used for generating the interpolation pixel; and an interpolation pixel generator generating a pixel signal of the interpolation pixel using a pair of pixels based on decision result of the correlation-direction deciding unit.

Video signal processing apparatus and video signal processing method

In an interpolation pixel generation circuit, M pairs and N pairs (N&#x3c;M) of correlation judgment pixels are generated from pixels on at least two scanning lines which adjoin a pixel to be interpolated, using one pair of pixels being symmetric with respect to the pixel to be interpolated. A correlation value between pixel values of a correlation judgment pair is calculated in each M pairs and N pairs of correlation judgment pixels. Correlation judging pairs having high correlation are selected, and correlation direction is judged. Based on the both judged correlation direction of M pairs and the N pairs of correlation judgment pixels, an interpolation priority direction is determined from a slant priority direction, a vertical priority direction, and a vertical top priority direction. An interpolation pixel is generated, which pixel value is an average of pixel values of the selected correlation judgment pixels being in the determined direction.
