Ink jet printing process

This invention has as its object to establish a wireless communication between wireless communication devices and to provide a desired service without any troublesome setup operations. To this end, a digital camera and printer of this invention have wireless communication functions. When it is determined that a wireless communication instruction is issued by a console of the digital camera, a beacon from a network is detected. Upon detection of the beacon, search request information used to confirm the presence of a wireless communication processing device on a network identified by network identification information included in the beacon is transmitted in accordance with that network identification information. If response information to this transmitted request information is detected, identification information of a partner wireless communication device included in the response information is stored, and is displayed to allow the user to select a connection target device.

Wireless communication system and wireless communication device and control method

There is provided an image processing apparatus for applying an adjusting process to an image including multicolor image signals. An image area including a pixel to be processed is extracted, and one representative signal value is generated from signal values corresponding to a plurality of colors of pixels included in the image area (S 2501 ). A feature amount associated with the image area is calculated based on the representative signal value (S 2503 , S 2505 , S 2511 ), and a substitute candidate pixel common to the plurality of colors is selected from the image area based on the calculated feature amount (S 2512 ). Signal values of the pixel to be processed are substituted by new pixel values, which are calculated from the signal values of the pixel to be processed and signal values of the substitute candidate pixel.

Image processing apparatus, image processing method, and image processing program

A recording system in which a DSC and a PD printer are directly connected to each other via a general interface, image data is transmitted to the PD printer from the DSC, and the data is printed, wherein a communication procedure is established by applications installed into the PD printer and the DSC, each of a plurality of functions serving as the printing system are assigned to either the DSC and the PD printer, data and a command are transferred between the functions assigned to the DS and the PD printer, and recording is performed by the PD printer based on image data supplied from the DSC.

Recording system and controlling method therefor

A digital camera has a storage medium which stores image data and a DPOF associated with a print process of the image data, acquires information associated with the function of a printer upon connection of that printer, sets a CDPS job command associated with the print process of the image data on the basis of the acquired information associated with the functions, sets a print condition for the printer on the basis of the DPOF and CDPS command, and sends a print instruction. The printer acquires image data stored in the storage medium in accordance with the designated print condition and prints the image data.

Image supply device, recording system, and recording control method

An adaptor which mediates between an image supply device and a printer causes the printer to print by selecting either of the first operation mode in which image data from the image supply device is received by wireless communication and before the completion of receiving the image data, a print job is issued to the printer by wired communication, and the second operation mode in which image data from the image supply device is received by wireless communication and after the completion of receiving the image data, a print job is issued to the printer by wired communication.

Adaptor, image supply device, printing system, and control method therefor

There is disclosed an image processing apparatus which applies an adjusting process to an image that includes a pixel to be processed. The image processing apparatus extracts an image area with a predetermined size including the pixel to be processed. The apparatus calculates a variation associated with the pixel to be processed from signal values of pixels included in the image area. The apparatus calculates a variation time count in the image area from the signal values of the pixels included in the image area. The apparatus calculates adjusting levels Fz1, Fz2, and Fe from the variation time count and the variation using a definition unit which defines correspondence among the variation time count, the variation, and the adjusting levels, and applies an adjusting process to a signal value of the pixel to be processed by the calculated adjusting levels. Note that the definition unit defines the correspondence so that the adjusting levels Fz1, Fz2, and Fe progressively change in accordance with different variation time counts or different variations.
