| Number | Title | Issue Date |
| 6947060 | Image forming apparatus, electron beam apparatus, modulation circuit, and image-forming apparatus driving method An image forming apparatus which performs pulsewidth modulation with a pulsewidth set by counting a clock. Especially, for grayscale level correction by setting the frequency of the clock, the periodic clock is counted, and an output pattern is changed in accordance... | 09/20/2005 |
| 6262771 | Method and apparatus for converting picture signal, and recording and reproducing apparatus A picture signal includes a luminance signal and a color signal. A first predetermined number of sample points of the luminance signal are located on every actual scanning line. A second predetermined number of sample points of the color signal are locate... | 07/17/2001 |
| 6067119 | Hierarchical low latency video compression A method for displaying a video sequence depicting motion of at least one video object by sequential presentation of a plurality of frames includes storing a low resolution representation of the video object, generating and displaying a first frame of the... | 05/23/2000 |
| 5424780 | Apparatus and method for spacial scan modulation of a video display An apparatus and method is shown for modifying the presentation of pixels displayed or printed on a raster or matrix image or graphic display or printer, thereby increasing the apparent image quality. Means for deriving a plurality of neighboring pixels o... | 06/13/1995 |
| 4710799 | High resolution color television The information signal for a green camera tube modulated to scan each line in an undulating path is sampled by a filter trap at the frequency of modulation in a narrow band (about &#b1;1/2 MHz) and combined with the red and blue camera tube signals in the... | 12/01/1987 |
| 4589012 | High resolution television A method and apparatus are disclosed for increasing vertical resolution of television and eliminating vertical aliasing by modulating vertical deflection of the camera a significant number of cycles per line, and modulating the vertical deflection of the ... | 05/13/1986 |
| 4533951 | System for generating and displaying a compatible high definition television signal by progressive scanning A high-definition camera uses sinuous or line scanning to produce wide bandwidth signals having high-definition in the horizontal and vertical directions. A wobble signal having a wobble chosen at an even integer multiple of one-half the line rate is used... | 08/06/1985 |
