摘要： PURPOSE:To quickly and accurately perform convergence adjustments by displaying information on the completion of correction of each adjusting point. CONSTITUTION:Dot patterns projected on a screen 32 represent adjusting points on which the convergence correction is performed. A television camera 30 detects convergence lag and, by its detecting signal, convergence amounts are automatically written in the memory of a digital convergence section 24. When corrections of an adjusting point are completed, a coincidence detecting signal is added to a pattern generating section 16 through a completion displaying counter 28 from a convergence coincidence detecting section 31, and the completion of the correction of the adjusting point is displayed on the screen 32. Corrections of each adjusting point are performed by repeating this procedure. Since adjusting points on which corrections are completed become clear, convergence adjustment is performed quickly and accurately.

摘要： PURPOSE:To easily execute a color matching, by adjusting a convergence by use of 2 kinds of adjusting pattern signals whose signal time widths are different each other. CONSTITUTION:A cross hatch picture is projected by a green projection Braun tube 3, a cross hatch picture whose width is wider than that of said cross hatch picture is projected by a red projection Braun tube 2, and these two pictures are picture- matched by use of a convergence adjusting circuit part 19. Subsequently, a blue picture is shifted to the green picture by changing over changeover switches 23, 24, the picture matching is executed, and three colors are synthesized. According to this method, the color matching is realized in a short time, comparing with a method by which it is executed gradually after it has been overcorrected once.

摘要： PURPOSE:To make adjustment in a short time, independently of skillness of an adjusting person, by detecting a shift of a convergence adjusting pattern pictured on a screen of a color TV receiver through the use of a TV camera storing the amount of directional movement corresponding to an address signal for the adjusting point. CONSTITUTION:A deflection circuit 25 scans electron beam via a deflection yoke 22 in synchronizing with an incoming synchronizing signal. A video circuit 7 pictures dot patterns from a dot generator on a screen 19 at convergence adjustment via a projection type reception tube 20. A part of the adjusting pattern pictured on a screen 29 is extended and detected at an image sensor 26, where an angle position shift amount corresponding to each adjusting point of a TV camera head 27 corresponding to the write-in address from an input section 31 is stored in advance. With the constitution like this, when the address for the adjusting point is designated to an input section 31, the convergence of the designated adjusting point is automatically adjusted with good reproducibility via a digital convergence section 24.

摘要： PURPOSE:To save memory capacity while shortening the time of an adjustment by storing correction values of respective adjustment points on crosses on a screen and/ or corner parts. CONSTITUTION:One-frame memory 31 consists of ROM and nonvolatile RAM; and high-order bits of correction data regarding respective adjustment points on crosses on a screen are written in ROM while low-order bits are written in RAM and those data are repeatedly read out. For fine adjustments, correction data of low-order bits are written via data reversible counter 34 by correcting the value of RAM. Next, the contents of memory 31 are read out and after interpolated, D/A-converted 9 to lead out convergence signals via LPF10. Thus, the adjustment time is shortened and ROM is repeatedly read to find the correction value of another adjustment point, so that the memory capacity can be saved. Further, corrections of high precision can be made covering the entire screen by writing correction value of screen corner parts.

摘要： PURPOSE:To make an adjustment of high precision in a short time by providing a fine adjusting function in addition to a previously-provided adjustment data regarding all adjustment points. CONSTITUTION:One-frame memory 31 consists of ROM32 and nonvolatile RAM33 and in ROM32, high-order bits, e.g., four bits of inherent correction values regarding all adjustment points are written as coarse adjustment values for coarse adjustments of the entire screen. In RAM33, on the other hand, correction data concerning all adjustment points are written for fine adjustments by data reversible counter 2. Next, the contents of memory 31 are read out and after interpolated, D/A-converted 9 to output convergence signals via LPF10. Thus, data for coarse adjustments are previously stored in ROM and there is no need to write then for adjustments, so that corrections of high precision can be made in a short time.

摘要： PURPOSE:To make corrections of high precision in a short time by making analog coarse adjustments and digital fine adjustments. CONSTITUTION:Analog convergence circuit 12 is driven by a pulse voltage or saw- tooth voltage obtained by deflecting circuit 37 to make coarse adjustment on crosses on a screen. On the other hand, horizontal and vertical pulses obtained from deflecting coil 37 drives digital convergence circuit 25 to fine adjustment of a shift in convergence mainly at the circumference of the screen. The outputs of two convergence circuits 12 and 25 are waveform-mixed by convergence yoke 39 with a correcting magnetic field. Thus, the coarse adjustments and fine adjustments are made, so that convergence corrections of high precision can be made in a short time.

摘要： PURPOSE:To shorten the time of the adjustment of convergence by providing the coarse adjusting function of making the coarse adjustment of the entire screen and the fine adjusting function of making the fine adjustment. CONSTITUTION:To make a coarse adjustment, a preset representative point, e.g., N1 is selected and a correction value is set in data reversible counter 2 and written in one-frame memory 17 and register 30. Next, the contents of register 30 are multiplied 31 by the coefficient of ROM32 to find representative points N2-N4, which are written in memory 17. Similarly, correction values of other representative points S1-, E1- and W1- are written in memory 17. Then, they are read out and after interpolated, D/A-converted 9 to output convergence siganals by way of LPF10. Thus, the coarse adjusting function is provided in addition to the fine adjusting function, so that the time of adjustment can be shortened.
