Abstract: This invention has as its object to detect an image area of interest in an image file by a method with a lighter processing load by making determination using characteristics of a quantization table. Since spatial frequency information, chromaticity information, and a quantization table are acquired for respective predetermined blocks from inputted compressed image data, and are used in combination upon searching the compression-recorded image data for an image of interest, information containing AC component information for each image data block is acquired without any advanced calculations, thus searching for the image of interest in the image file.

Abstract: A data transmission system where an image providing device and a printer are directly connected by a 1394 serial bus, a command is sent from the image providing device to the printer, then a response to the command is returned from the printer to the image providing device. Image data is sent from the image providing device to the printer based on information included in the response. The printer converts the image data outputted from the image providing device into print data. Thus, printing can be performed without a host computer by directly connecting the image providing device and the printer by the 1394 serial bus or the like.

Abstract: In response to a request from a host device using an initial protocol, capability information including information indicative of a plurality of communication protocols is returned to the host device, and a communication protocol, designated by the host device based on the capability information, is set, and print data is received from the host device by the set communication protocol. In a system using an interface connected to various types of devices, e.g., an IEEE 1394 serial bus, a communication protocol, which is used when a host device transfers print data to a printer, is not limited to that unique to the manufacturer of the device.

Abstract: An image area of interest in an image file can be detected by a method with a relatively light processing load by making a determination using characteristics of a quantization table. Since spatial frequency information, chromaticity information, and a quantization table are acquired for respective predetermined blocks from inputted compressed image data, and are used in combination upon searching the compression-recorded image data for an image of interest, information containing AC component information for each image data block is acquired without any advanced calculations, thus searching for the image of interest in the image file.

Abstract: In outputting of image data, the image data is converted into color space data suitable for outputting means, and thereby a color reproducing capability of the outputting means is utilized. Thus, the image data is read, the image data is converted into first color space data, the image data is converted into second color space data, the first color space data is outputted to first outputting means, and the second color space data is outputted to second outputting means.

Abstract: In a system where a digital still camera 1101 is connected to a printer 1102 on a 1394 serial bus, when the digital still camera 1101 as a data transfer originator node transfers image data to the printer 1102 as a data transfer destination node, the printer 1102 sends information on the data processing capability of the printer 1102 to the digital still camera 1101 prior to data transfer. The digital still camera 1101 determines the block size of image data to be transferred in accordance with the data processing capability of the printer 1102, and sends image data of the block size to the printer 1102. The information indicates the capacity of a memory of the printer for storing print data, or the printing capability of a printer engine, i.e., printing resolution, printing speed and the like. Thus, data transfer is always efficiently performed regardless of the data processing capability of the printer 1102.

Abstract: If a block read cannot be used to read out from a configuration ROM information, the number of times of issue of a quadlet read request increases. This degrades the processing efficiently of a device that issues the request. In addition, the bus occupation ratio of a 1394 serial bus by the request becomes high, and the speed of processing through the 1394 serial bus decreases. To solve these problems, information stored in the configuration ROM area of a device is read out, and it is determined on the basis of the readout information that configuration information identical to the configuration ROM information is stored in an address area (block readable area) different from the configuration ROM area, the offset is changed, and the configuration information is read out from the address area different from the configuration ROM area.

Abstract: In a 1394 network where a number of devices are connected, it is not easy to specify corresponding between a displayed device and a real device. Accordingly, “selection-candidate update processing” to find a new device and “processing for displaying candidates meeting set conditions” to display candidates which meet set conditions are provided, so as to display a device list window displaying selection candidates in a case where a set condition is, e.g., “printer”.

Abstract: An information processing apparatus comprises: a memory to store emulation information which is designated from a host computer that is connected to a printer via a general parallel interface; a judging circuit to judge a delimiter of print data; and a control unit to switch the emulation on the basis of the emulation information stored in the memory and the result of the judgment by the judging circuit. When each section of the apparatus is in the inoperative state, they are set into the power saving mode and are sequentially controlled. Thus, the power saving of the whole apparatus can be realized.
