Title: Digital processing circuit of video signal
Inventor: KONUMA TATSURO
IPC: H04N9/74
Filed: 1985-01-10
Abstract: PURPOSE:To reproduce a half tone with a simple constitution by outputting a digital signal in accordance with the result to compare successively at the prescribed period respective levels of a three primary colors signal with one of plural mutually different reference levels. CONSTITUTION:Respective red, green and blue signals from an NTSC decoder 1 are compared with the voltage derivated to the output terminal of a change- over switch circuit 16 in comparators 3, 4 and 5. Reference voltage Vr2 and Vr3 are impressed to two input terminals of the change-over switch circuit 16, and this is derivated alternately selectively at every 1H by a control signal. Thus, when red, green and blue signals are outputted in the section of continuous 2H, digital data with different binary levels are obtained, the arrangement of colors on two scanning lines obtained at the section of 2H goes to be different, and a neutral tint can be macroscopicly obtained.

Title: Ink jet recording method
Inventor: MAEDA HIROYUKI
IPC: B41J2/01
Filed: 1989-01-11
Abstract: PURPOSE:To record high-quality images by specifying each dot gap in a direction substantially perpendicular to an image-recording direction. CONSTITUTION:Dots are so formed that each dot gap in a direction substantially perpendicular to an image-recording direction satisfies the inequality: (dot gap) <=25400/AX7/10mum, wherein A is the number of dots per 2.54cm on a recording material in a direction substantially perpendicular to the image-recording direction. The dot gap can be controlled by, for example, a method as follows. All dots of a recording head 5 are driven to record images 1 for one line, and the gap between adjacent dots constituting the images is detected by a sensor 2. When the dot gap is too large to satisfy the inequality, a heater 4 is immediately controlled by a temperature controller 3 to heat the head 5 wholly, thereby increasing the quantity of each recording liquid droplet ejected from an ejecting port of the head 5, resulting in an increase in the diameter of reach recorded dot and a reduction in the dot gap.

Abstract: PURPOSE:To perform the inference processing at a high speed by extracting all candidates of experience rules for evaluation based on the past inference results and using those candidates to the subsequent inference as long as said candidates are correct. CONSTITUTION:An inference part 5 fetches the work data under progress and the work data to be executed, i.e., the variable data from a data fetching device 4. Then it is checked whether the work under progress overlaps or not the work to be executed in terms of time.

A pair of the inference result of a problem and the variable data, if not stored yet, are stored in an inference result memory part 9 every time the inference processing is carried out. The experience rules are produced based on the attributes of said recorded data and the situation data recorded to a variable data attribute memory part 15. These experience rules are delivered to an output device 13 to be evaluated at an experience rule evaluating part 11 or corrected by the input given from an input device 12. The experience rules which are decided correct at the part 11 are stored in the part 7 and used to the subsequent interferences.

Title: Method and system for transmitting image
Inventor: HATTA HIROYUKI
IPC: H04N7/16
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To detect switching an image to an image from a video source by monitoring decoded RGB signals from NTSC signals inputted from the outside and detecting the presence/absence of a change in the image. SOLUTION: Video signals sent from a video center 2 are converted to digital RGB signals by an NTSC decoder 11. An image detection part 20 monitors these RGB signals and when a certain one color or color bar is shown within a vertical synchronizing cycle, it is discriminated that a moving image from the video center is received. When this discrimination is performed, the image detection part 20 writes the discriminated result into any suitable register inside a moving image fetch card 5. Thus, a CPU at a main body 10 of personal computer always monitors this register through a CPU bus 16 so as to detect the switching to the image from the video source.
