According to this invention, the date range can be intuitively designated by designating up, down, left, and right directions, and images stored in a storage medium can be easily restricted to images which may be subjected to printing. In order to restrict images stored in a memory card on the basis of the date, a region for inputting the start date of the date range is displayed at the upper portion of a display window on a display device, and a region for inputting the end date is displayed at the lower portion. One of the regions is designated and selected with up and down direction keys. A date in the selected region is changed with left and right direction keys. Images having storage dates between the start date and the end date are decided as printing target candidates.

Printing apparatus, method, and program for selecting, displaying, and printing group images

An image printing apparatus and its control method for printing an image based on image data from an image data source. In a case where a correction condition is set for the image data, if the image data is a new format file image data including predetermined information, correction processing is performed in accordance with the set correction condition. If the image data is not a new format file image data, the correction processing in accordance with the correction condition is not performed.

Image printing apparatus, image printing system and control method

This invention has as its object to receive image data from image sensing apparatuses of various manufacturers and to print a high-quality image by making image data transfer and a printing instruction, which are independent from interfaces. Since an image sensing apparatus such as a digital camera or the like calculates image feature amounts, and transfers the calculation result to a printing apparatus, huge image data need not be transferred from the image sensing apparatus to the printing apparatus again and again, and a high-quality image can be output. Upon printing image data transmitted from a digital camera (DSC) () to a PD printer (), after a protocol is established by applications (NCDP) installed in the PD printer and DSC, the PD printer transmits its Capability list to the DSC. The DSC calculates an image feature amount of a selected image to be printed, and transmits the calculation result to the PD printer. Upon reception of this information, the PD printer makes image correction based on that image feature amount, and records (prints) an image.

A printer and a digital camera are connected so as to be capable of communicating with each other. The printer transmits information indicative of its capabilities to the digital camera and the digital camera incorporates the transmitted printer capability information in a print settings menu. The capability information has information relating to the printer capabilities and information indicative of a default setting. The capabilities of the printer are incorporated in the print settings menu together with the default setting. A desired printing condition can be set selectively at the digital camera using the print settings menu in which the capability information has been incorporated.

Conveyance of information relating to printer capability

A printing apparatus is equipped with multiple interfaces adapted to connect external devices adapted to store image data and operated by power supplied from a first-connected external device, and is adapted to print images stored in the external devices. The state of the connection of the external devices to the plurality of interfaces is detected and, when it is determined that a plurality of external devices are connected to the printing apparatus, a determination is made as to whether or not an amount of power required by the plurality of external devices exceeds the amount of power the printing apparatus is capable of supplying. If the amount of power requested exceeds capacity, then the apparatus selects which external device to supply with power depending on the operating state of the first-connected external device.

A CPU generates a mask pattern by generating patterns corresponding to a predetermined number of times in the sub-scanning direction in accordance with the number of printing elements of a printhead which corresponds to the amount by which scanning is performed once in the sub-scanning direction, and repeating this operation by the number of times corresponding to a predetermined number of columns. The generated mask pattern is stored in an RAM. An image is then printed by using image data and the mask pattern stored in the RAM for each printing timing signal in the main scanning direction.

A print-direct printer for receiving and printing JPEG data from a DSC divides the area of a memory into a plurality of blocks, stores the received JPEG data in the memory on a block-by-block basis and decompresses the compressed JPEG data that has been stored in the memory, thereby expanding the JPEG data into image data. If it is determined that JPEG data to be expanded next has not been stored in the memory, then the DSC is requested for JPEG data corresponding to at least one block, in an amount that is less than the maximum amount of data transferable from the DSC, in addition to the JPEG data to be expanded.

Image printing apparatus and image printing control method

A printing apparatus can quickly cancel a print job without any influence on the other subsequent print jobs when a print cancel instruction is issued. During printing, if a print cancel instruction is inputted from a printer operation unit, a printer function manager notifies a print command interpreter of the cancellation. The print command interpreter searches data processed at that time in a transmission/reception buffer for an end mark command indicating the end of the cancelled job. Then the print command interpreter deletes the data before the end mark command.

An information processing apparatus comprising a power unit, a first control unit and a second control unit in which power supply is controlled based on a control signal from the first control unit, wherein when electric power supply from the power supply unit has been stopped and then the electric power supply from the power supply unit has been started, if update of a memory of the first control unit has been instructed, the first control unit transfers the content of a flash ROM in the first control unit into the memory thus updates the content of the memory. At this time, the second control unit is kept in a power-off status by a control signal line until the update of the memory is completed. After the completion of the update, power-on is notified by the control signal line, and the reset status of the second control unit is released.
