A recording method for use in a recording system for completing an image by multiple scans of a recording head includes the steps of reading an image recorded by a predetermined number of scans among the multiple scans of the recording head except at least the last scan, and correcting, based on a result of reading the image in the reading step, data for an image to be recorded by one or more scans subsequent to the predetermined number of scans. An image is correctively recorded by performing one or more scans subsequent to the predetermined number of scans in accordance with the corrected data.

Recording method and recording apparatus capable of reducing streaks and unevenness in image density

Density correction method capable of performing density correction at high speed with high precision. In a printing apparatus adopting this method, a predetermined test pattern image is printed on a printing medium, the printed test pattern image is optically read by a sensor at first resolution, the quality of the read image is evaluated, based on the evaluation result the printed test pattern image is optically read by the sensor at second resolution higher than the first resolution, and correction data is generated based on the read test pattern image.

A transport system composed of road side stations installed along roads and vehicles running on roads, wherein emergency processing at the time of an accident, a local information providing service, and so on are realized by the road side stations in cooperation of the road side stations and the respective vehicles. In the transport system, a plurality of road side stations are interconnected through a road side communication network, and a plurality of vehicles communicate with the road side stations. A vehicle transmits a request message containing a service code and location information. A road side station receiving the request message broadcasts the request message to the network. The road side stations receive the message, and determine whether or not requested processing should be executed based on the service code and the location information. When determining that the processing should be executed, the road side station executes processing indicated by the service code.

A method for collecting and processing information from a vehicle is disclosed. The information is useful for providing a loss-insurance coverage. The method includes the following steps: (a) Information is automatically transmitted from the vehicle to a central vehicle-information management center, the information including information regarding a position of the vehicle, information regarding control of the vehicle, information regarding states of parts of the vehicle, a type of the vehicle, and identification of a user of the vehicle. (b) The central vehicle-information management center computes a utilization service fee based on the type of the vehicle and the identification of the user transmitted in step (a). (c) The central vehicle-information management center transmits the computed fee and a request for confirmation to the vehicle. (d) The vehicle transmits a response to the central vehicle-information management center as to whether the user will effect insurance coverage.

Two lines extending in the main scanning direction build a set of lines (L , L ) each of which is formed by a plurality of dots. Assignment is alternately executed to preceding scanning and subsequent scanning so as to allow each of the lines (L , L ) formed by a number of pixels (P , P , P , P , P , P , P , P , - - - ) to extend along a snake movement-like route. Thus, dots located adjacent to each other in the auxiliary scanning direction are not formed by same scanning, and a quantity of ink spreading on a recording medium without penetration of the ink through the latter can be reduced. Consequently, there few arises stripe and fluctuation in density, whereby an excellent quality of image having sharp edge portions can be obtained without any occurrence of a problem attributable to the presence of unfixed ink.

A method o gathering and analyzing vehicle information is disclosed. A central vehicle-information management center gathers first vehicle information gathered in real time, including position of the vehicle, control of vehicle, and conditions of vehicle parts, and gathers second vehicle information including vehicle type, vehicle identification number, and information regarding users of the vehicles. The central vehicle information management center performs a statistical analysis for the plurality of vehicles based on the first and second information. The first information is transmitted by a transmitter provided on each vehicle, and acquired via a satellite communication system and/or a land-based wireless communication system.

An ink for ink-jet recording which comprises (a) a coloring material, (b) a liquid medium, and (c) an ammonium salt of an acid having a methyl or methylene group and a carboxylic group, or an ammonium aldonate, or an ammonium salt of citric acid, to alleviate kogation of the ink-jet head heater having an outermost protecting layer containing at least one of a metal and a metal oxide.

It is an object to provide an ink-jet recording apparatus capable of always obtaining an image having a high quality without difficulty for a user by precisely detecting a cause which deteriorates image quality and by efficiently resolving the cause. The cause of the deterioration in image quality is detected on the basis of a difference S between image data G intended to be recorded and read data Y which is obtained by reading the image that is recorded on a recording medium (S&equals;G&minus;Y), thereby determining a processing method for resolving the cause. The determined processing method is executed and, thus, normal recording is always possible.
