Definitions

  • the present invention relates to an image supply device such as a digital camera, a recording apparatus, a recording system, and a control method therefor.
  • a color print system which allows a digital camera to directly transfer digital image data to a color printer without the intervention of any PC and can print it out
  • a so-called photo-direct (PD) printer in which a memory card that is mounted in a digital camera and stores sensed images can be directly mounted in the color printer and sensed images stored in the memory card can be printed have recently been developed.
  • a printer which directly receives image data from a digital camera and prints the image can also receive print data from a PC or the like in addition to the digital camera and print the data. For this reason, a response to a command from the digital camera may delay due to issuing of a print request from the PC when a pre-procedure for receiving image data between the printer and the digital camera is executed. For example, when a print start request is issued by the digital camera and received by the printer, a status representing that the next command can be accepted changes from "true” to "false", and the camera is notified of this status. If, however, e.g., a print request is simultaneously issued from a PC, the printer cannot quickly notify the camera of the status change.
  • the present invention has been made in consideration of the above situation, and has a feature to provide an image supply device which, when a response coping with a procedure determined in advance between the image supply device and a recording apparatus is not received from the recording apparatus , determines that the status of the recording apparatus is a status estimated from a normal procedure, and decides subsequent process procedures, a recording apparatus, a recording system, and a control method therefor.
  • an image supply device used in a recording system in which the image supply device and a recording apparatus are directly connected via a communication interface, and image data is transmitted from the image supply device to the recording apparatus and recorded, characterized by comprising: reception means for receiving status information from the recording apparatus; determination means for determining whether said reception means has received predetermined status information from the recording apparatus within a predetermined time period after the image supply device issues a predetermined command to the recording apparatus; and process means for, in a case where the determination means determines that no predetermined status information has been received, determining a status as a status to be estimated from a normal process, and continuing a process.
  • a recording apparatus used in a recording system in which an image supply device and the recording apparatus communicate with each other via a communication interface, and image data is transmitted from the image supply device to the recording apparatus and recorded, characterized by comprising: command issuing means for issuing a predetermined command to the image supply device; reception means for receiving a signal from the image supply device after the command issuing means issues the predetermined command; determination means for determining whether the signal received by the reception means is a response corresponding to the predetermined command; and control means for controlling an issuing timing of a next command to the image supply device in a case where the determination means determines that the signal is not the response corresponding to the predetermined command.

Il est ensuite déterminé si les informations d'état prédéfinies sont reçues par l'imprimante directe durant une période de temps prédéfinie après que l'appareil photographique fixe numérique émette une commande prédéfinie à l'imprimante directe. S'il est déterminé que les informations d'état prédéfinies ne sont pas reçues, l'état est déterminé comme étant l'un des états estimés dans un procédé normal, et le procédé continue. Afin de confirmer l'état de l'imprimante directe, l'appareil photographique fixe numérique demande des informations d'état de l'imprimante directe, et acquiert l'état de cette imprimante sur la base des informations d'état envoyées en réponse à la demande.
