摘要： In order to enable sampling of high definition still video signals in addition to common video signals, a function is added for sampling video signals with every other plurality of picture elements as an interval to an image processing apparatus without using a sampling circuit which requires high speed operations. The invention is also intended to change over between two circuits that is, a circuit for using a picture element clock regenerated by a PLL circuit as a sampling clock for analog to digital converters and a circuit for using a clock obtained by dividing the picture element clock as a sampling clock for the analog to digital converters to sample video signals with every other plurality of picture elements as an interval. Thus, it is possible to carry out sampling of high definition video signals with high frequencies in addition to common video signals without necessity of raising the operating speed of the sampling circuit.

摘要： A uniformity correction signal generating apparatus includes a horizontal address signal generating unit and a vertical address signal generating unit for generating address signals (X) and (Y, y) having one-to-one correspondence to a position on a display screen of a display unit, respectively. Upper and lower adjacent lattice point data are read out from an E.sup.2 PROM on the basis of the address signals X and Y. Interpolated correction data are obtained on the basis of the upper and lower lattice point data and vertical lower address coordinates y. The apparatus is suitable for an auto-scan type display unit and can correct the uniformity for gradation and focus by using the inexpensive E.sup.2 PROM without need of a large capacity expensive E.sup.2 PROM.

摘要： An adaptive crosshatch signal generator includes a frequency detector for detecting a horizontal scanning frequency, a square calculator supplied with the detected output of the frequency detector, and a variable pulse width multivibrator controlled to have an output pulse width substantially in inverse proportion to the squared output. Longitudinal lines of a crosshatch signal are formed by the output pulses of the multivibrator. The crosshatch signal has a longitudinal line width which is always substantially equivalent to the distance between adjacent scanning lines and is generated by using a simplified configuration irrespective of input signal format.

摘要： It is an object of the invention to provide a large-screen projection type display capable of reducing the moire interference due to the periodical structure of the linear Fresnel lenses and lenticular lenses. Since the moire interference is attributed to the shades S generated from the Fresnel sheet 1, these shades are diverged at a divergence angle .epsilon. by the action of the small-pitch lenticular lenses 4, so that the shades can be eliminated on the light-incident side surface of the lenticular sheet 3 which is located at a distance D from behind the Fresnel sheet.

摘要： In a grid drive-type CRT display apparatus, the impedance of a second grid voltage supply circuit is made a high impedance and a low-frequency band rejecting streaking interference caused by the high impedance is compensated by low-frequency range emphasizing circuit means. The low-frequency range emphasizing circuit means compensates for the low-frequency range rejection characteristic which is an adverse effect of the high impedance to the second grid and this results in an improvement in the high-frequency transmission characteristic. Also, there is the effect of improving the frequency bandwidth and reducing the consumption of power.

摘要： A convergence correction circuit according to the present invention has a phased locked loop including a programmable counter. The programmable counter has programmable count start and end points. The output of the programmable counter is supplied to a memory storing convergence distortion correcting data therein. As the horizontal screen size is increased, a value closer to the lower limit 0 of the start point as compared with that taken when the horizontal size is small is set as the count start point of the programmable counter, and a value closer to the upper limit (2.sup.7 -1) of the end point as compared with that taken when the horizontal size is small is set as the count end point. In accordance with the horizontal screen size, the count start and end points of the programmable counter are changed. Correct convergence correction is performed even if the horizontal screen size is changed.
