Title: Inter-station control system
Inventor: ASAMA TOSHIHIKO
IPC: H04Q1/30
Filed: 1991-12-28
Abstract: PURPOSE:To reduce the line cost without deteriorating the reliability by using a layer 3 protocol having a re-transmission function of a control message and a layer 2 protocol implementing data transfer only in the information transfer mode not confirmed. CONSTITUTION:Transmittal of a data unit is not confirmed in the layer 2 of this system, and even when a format error takes place in the received data unit, the processing is up to abort of a frame and the layer 2 itself cannot recover the error. As soon as a layer 3 of a station A transfers a control message to a station B via a station A side layer 2, a watchdog timer is started and a reply control message is awaited. Should the communication between layers 3 be interrupted due to loss of the data unit of the level of the layer 2 or the like, the station A side layer 3 transfers again the control message after the expiration of the timer. Thus, the load of the control processor of the layer 2 and the quantity of the hardware are relieved and the cost is reduced.

IPC: H04N1/46
Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To allow an output device to convert a color shown by an input color image signal into an apparently desirable color. SOLUTION: A 1st color conversion section 3 matches a lightness range of a color reproduction possible area of an input side with a lightness range of a color reproduction possible area of an output side, adjusts the lightness with a maximum saturation with a prescribed function and sets a medium color reproduction possible area and converts the input color image signal into the medium color image signal within the medium color reproduction possible area. Furthermore, a 2nd color conversion section 4 takes an achromatic color with a lightness at a point in the output side color reproduction possible area at which a maximum saturation is realized as a target point and keeps the lightness when the lightness of the medium color image signal is higher than the lightness of the target point to apply conversion processing to the saturation.  Furthermore, when the lightness of the medium color image signal is lower than the lightness of the target point, the conversion section 4 applies conversion processing to the lightness and the saturation in a direction of a line segment tying the color of the medium color image signal and the target point.
