摘要： A circuit within a video monitor for making corrections during horizontal scan includes a data storage device containing information relating to a selected display parameter, an integrator receptive of the stored information and adapted to produce an integrated signal therefrom, and an amplifier receptive of the integrated signal for supplying signals to the video monitor based on the integrated signal. The information supplied from the data storage device to the integrator is encoded in a pulse density modulated waveform via a tri-state gate and a one-shot timer. The information stored in the data storage device is stored in bytes, each byte containing a "sign bit" and a plurality of data bits. The present invention also discloses the use of an on-screen display chip that uses stored fonts to generate a pulse-density modulated signal. Gradients between rows of fonts can be generated using selected fonts from a font gradient table or can be produced using an up-down counter. Gain matrix tables are also disclosed that reside in the vision system to aid the vision system in predicting proper alignment of less intelligent monitors. Gain matrix table data can also be supplied to the monitor correction table so as to provide updated intelligence to the monitor.

摘要： An apparatus and method are disclosed for generating timing pulses to control various functions in a video monitor including the switching of video amplifiers in cathode ray tube (CRT) devices, the control of the phase and frequency of phase locked loops, etc. Unlike previous methods, where switching is timed and controlled by monitoring the retrace voltage level, the system of the present invention monitors the change in direction of current in the retrace tuning capacitor. Monitoring the retrace capacitor current, provides an extremely accurate method for timing in horizontal deflection circuits. The apparatus of the present the invention comprises a small bead inductor placed in the current path of a horizontal retrace capacitor within the horizontal deflection circuit of the cathode ray tube device. Measuring the voltage across the bead inductor allows a very precise monitoring of the current through the retrace tuning capacitor. By designing the size of the bead inductor as disclosed, precise electrical pulses can be generated and detected during the retrace time of the CRT electron beam. These precise pulses are then used to generate accurate control signals for use within the CRT device. The invention also discloses an apparatus and method that minimizes left side ringing distortion in cathode ray tube video displays. Left side ringing is reduced due to the addition of the bead inductor to the horizontal deflection circuit, which lowers the stray resonant frequency within the horizontal deflection circuit.

摘要： A interpolation engine is disclosed that is capable of generating correction signals for segments of a monitor that form a gradient that eliminates any visual discontinuities between segments on the screen. In one embodiment, a starting count number for a distortion signal is stored in RAM, together with an increment rate signal that indicates the rate of change of the correction signal down the segment. In another embodiment, the increment rate signal is automatically calculated by the device by taking the difference between the starting count numbers for vertically adjacent segments. Since the number of rows in each segment is known and the difference between the starting count numbers of vertically adjacent segments is determined, the amount of correction for each row within a segment is calculated and provided as a correction signal. Hence, a correction signal can be provided for each row of pixels on a screen. This information can be integrated to form a smooth correction signal or need not be integrated for vertical geometry corrections since a correction signal is provided for each row. The present invention only requires a minimal amount of storage of data and is capable of providing correction signals for each row of pixels.
摘要翻译：公开了一种内插引擎，其能够产生用于形成梯度的监视器的段的校正信号，该梯度消除了屏幕上的段之间的任何视觉不连续性。在一个实施例中，用于失真信号的开始计数号码与指示校正信号沿着该段的改变速率的递增速率信号一起存储在RAM中。在另一个实施例中，通过取垂直相邻段的起始计数号之间的差异，装置自动计算增量率信号。由于每个段中的行数是已知的，并且确定垂直相邻段的起始计数之间的差异，所以计算段内每行的校正量并将其提供为校正信号。因此，可以为屏幕上的每行像素提供校正信号。由于为每行提供校正信号，所以可以将该信息集成以形成平滑校正信号或不需要集成用于垂直几何校正。本发明仅需要最少量的数据存储，并且能够为每行像素提供校正信号。

摘要： A system and method for dynamic adjustment of video images on a cathode ray tube in diverse geographic local magnetic fields. The present invention uses a CRT magnetometer that accurately senses differences in the strength and direction of a local magnetic field in three axes, i.e., the x, y, and z axes. The cathode ray tube includes a digital monitor board or monitor circuitry that has a processor and memory and is capable of retrieving correction factor data and magnetic correction data generated by a vision system. The digital monitor board receives CRT magnetometer signals and uses the signals with magnetic correction data to adjust the correction factor data to generate locale specific correction factor data for the sensed local magnetic field. The digital monitor board is capable of decoding the locale specific correction factor data using DACs, PDMs, PWMs, and interpolation engines to generate correction signals that are used to adjust the video image to correct for magnetically induced distortion.

摘要： A system for transforming coordinate systems in an automated video monitor alignment system includes a camera and computer to capture an image of the display bezel surrounding the cathode ray tube and of the image displayed on the CRT. Three dimensional models of the CRT tube and display bezel are used to compute and compensate for camera perspective. Camera pixel data can then be transformed to `flat plane` coordinates. When the relative orientation of the camera and CRT are corrected, the effects of parallax can be eliminated, allowing more accurate inspection, measurement, and lower cost fixturing on the production line. Thus, an accurate coordinate transformation from a camera-referenced coordinate system to a monitor-referenced coordinate system is made. Correction factors for correcting errors due to refraction can also be generated empirically in accordance with the present invention. Slope coordinate data is generated for a sample monitor for predetermined slope coordinate locations on the tube face. Correction signals can be generated from the slope coordinate data and measured tilt angles of the monitor relative to the vision system. Two dimensional interpolation techniques can be employed to provide slope coordinate values and correction signals for video signals that do not physically match the location of the slope coordinate locations of the sample monitor.

摘要： A system for generating correction factor data that is representative of the distortion characteristics of a cathode ray tube. The correction factor data is stored with a cathode ray tube to allow later alignment of a video signal, or can be provided on a storage medium or on a network. Distortion data, and resultant correction factor data is generated for a series of discrete physical locations on the cathode ray tube screen. In this manner, the entire screen surface can be utilized to align a video image. Maximum correctable distortion data is also generated in accordance with the present invention to provide exit criteria for cathode ray tube manufacturers. The exit criteria is based upon maximum correction factor data that can be generated to correct distortions. A characterization module is provided that can be coupled to cathode ray tube coils that stores the correction factor data or an identification number for the cathode ray tube that can be used to retrieve the correction factor data from any desired source such as CD ROMS, a LAN, a database coupled to a WAN, or the Internet, etc. Interpolation techniques can be used to generate correction factor data for any desired number of interpolation points based upon correction factor data provided for a lesser number of characterization locations.
