A recording medium removable from a host device includes a wireless communication unit for performing wireless communication with an external device different from the host device. The recording medium includes an image transmission control unit which transmits image data to the external device via the wireless communication established by the wireless communication unit by using an image transmission protocol. The recording medium switches which of the image transmission control unit of the recording medium and an image transmission control unit of the host device is used to communicate with the external device via the wireless communication unit.

Recording medium and control method thereof

This invention has as its object to allow an authentication process that avoids unnecessary information from being stored in a digital camera irrespective of whether or not a digital camera connected to the printer has a direct print function. To this end, in this invention, in an early stage of connection between a digital camera DSC and PD printer, the PD printer side requests an object which contains a keyword as authentication information of those which are stored and held by the DSC (S). As a result, after it is determined the returned information contains authentication information, the printer notifies the DSC of its own authentication information (S).

Printing apparatus and control method thereof, and printing system

This invention completes an authentication procedure early when it is ready to directly communicate with a printer, and serves as a user interface device of a direct print system. To this end, when a digital camera DSC is ready to directly communicate with a printer, and receives from the printer an inquiry about objects stored and held by the camera, it assigns an object which contains a word serving as authentication information of those stored and held in the DSC to a first handler (S), assigns other objects (image data and the like) to subsequent handlers (S), and sends that assignment result to the printer (S).

Direct printing authorization in a digital camera

A cell type page which displays a fixed number of images at fixed positions with fixed size on a screen and a free type page which displays equal to or more than one image at arbitrary positions with arbitrary size on the screen are provided. In response to an image insertion order in the cell type page, images belong to the cell type pages behind that cell type page are sent astern without influencing positions of images belong to the free type pages behind that cell type image and blank pages are added if there is no blank cells. In response to an image deletion order from the cell type page, images behind an image to be deleted belong to the cell type pages behind that cell type page are closed ahead without influencing positions of images belong to the free type page behind that cell type page and the blank pages are deleted if the blank pages are appeared.

Image processing apparatus, image processing method and storage medium

An imaging apparatus capable of outputting a sensed image to a printing apparatus determines the type of PD printer apparatus connected via an interface, and selects the type of image data to be output to the PD printer apparatus on the basis of the determination result. The imaging apparatus directly transmits a JPEG code for a predetermined PD printer apparatus, or decodes and transmits the JPEG code for another printer apparatus.

Imaging apparatus, system having imaging apparatus and printing apparatus, and control method therefor

An object of the present invention is to easily search data from a recording medium on which different types of data items are recorded. A storing apparatus is disclosed, that comprises a signal processing unit for acquiring first type data and second type data and processing them, a serial number assigning unit for sequentially assigning a serial number to the first type data and the second type data processed by the signal processing unit in the acquired order regardless of the first type data or the second type data, and a storing unit for storing the first type data and the second type data corresponding to the serial number.

Recording apparatus, reproducing apparatus, recording method, and reproducing method

An imaging apparatus capable of outputting a sensed image to a printing apparatus issues a print request command containing a parameter for designating a print mode to a PD printer apparatus connected via an interface. The imaging apparatus transmits image data corresponding to the print mode on the basis of a data request from the PD printer apparatus. The imaging apparatus transmits, to the PD printer apparatus, the print request command in which the parameter is changed to invalid data, thereby designating printing of the transmitted image data.

An imaging apparatus capable of outputting a sensed image to a printing apparatus designates, to a PD printer apparatus connected via an interface, e.g., an index print or layout print mode in which a plurality of images are printed on one print medium. In printing in this print mode, the imaging apparatus counts the number of printed sheets in accordance with the number (total) of images printed on one sheet and the number (current) of actually printed images.

In a case where a digital still camera and a printer are connected to each other and marginless printing of an image stored on a memory card provided in the digital still camera is performed on a recording paper, a non-print area of the image not to be printed on the recording paper is displayed on a display of the digital still camera on the basis of a difference between an aspect ratio of the image and an aspect ratio of the recording paper, and the displayed non-print area is set to be able to be shifted in arbitrary directions by using an operation unit of the digital still camera.
