Abstract: A plurality of data storing servers 3 are connected on a communication network 6. A plurality of cameras 2 connected with the communication network 6 are divided into a plurality of groups, and the respective groups are related to the respective data storing servers 3 in correspondence. The respective data storing servers 3 import images from the cameras 2 belonging to the corresponding groups and store the imported images. If a request for the supply of an image to the camera 2 or the data storing server 3 is entered by means of an entry unit 28 in a PC 4, information representing this request is transmitted from the PC 4 to the camera 2 or the data storing server 3 via the communication network 6. Upon the request of the image from the PC 4, the camera 2 transmits an image obtained by a photographing operation in a target area to the PC 4 via the communication network 6. Upon the request of the image from the PC 4, the data storing server 3 supplies a requested image stored therein to the PC 4.

Abstract: An ink jet printer includes heads for jetting ink of yellow, magenta, cyan and black, and a head for jetting ink lower in tone than the aforementioned ink. The voltage applied to a head can be changed to change the size of a dot to be printed. Tone control can be provided depending on the tone of ink and dot size to improve image quality.

Abstract: The process described below is performed to output high-quality images without changing the resolution of the printer used. A binarizing step using such a frequency modulation (FM) technique as error diffusion is performed. at a resolution higher than that which, can be output from the printer. A screen or grid corresponding to the resolution of the printer is superimposed on the binarized data. A size of a dot to be printed by the printer is obtained from the number of dots (or data indicative of a “1”) contained in one square of the screen. Then the diameter of the dot is modulated while an image data is output depending on the resolution of the printer.

Abstract: The present invention relates to an ink jet recording apparatus using an electrostatic actuator. The present invention provides an ink jet recording apparatus comprising a resilient oscillating plate that is facing a pressure chamber that communicates with a nozzle, a first electrode provided on said oscillating plate, a second electrode opposing said first electrode across a space, and a voltage application unit that applies across the first electrode and the second electrode a first voltage that causes the ink in said pressure chamber to be ejected and a second voltage that does not cause the ink to be ejected, wherein said second voltage is applied a specified time prior to the application of the first voltage, so that the residual electrical charges on the first electrode and/or the second electrode can be positively discharged.

Abstract: In order to provide an ink jet printer achieving a constant printing quality regardless of the type of sheet to be used, a switch for selecting the type of sheet for the printer is provided. The type of sheet to be used is determined according to the state of the switch. Based on the result of the determination, the diameter of an ink drop emitted from a nozzle is changed. Since the degree of spreading of ink as well as the degree of absorption of ink differ depending on the type of sheet, the image quality after printing can be made constant regardless of the type of sheet by changing the diameter of ink drops.
