An electronic system comprising an image pickup unit, a computer, and communication terminals for connecting the unit and the computer, such as infrared communication ports, a card slot, and serial communication terminalswherein the necessary image data is allowed to be produced from the unitand transmitted to the computer through the communication terminals. The computer communicates with the image pick up unit by examining the port of each communication means in order to recognize whether a connected unit is the image pickup unit or a foreign unit and to determine and store the communication speed for each communication port. The image data and memory space information is then automatically transmitted to the computer and displayed on a device connected to said computer.

Electronic apparatus

In an image reproducing apparatus according to the present invention, image printing apparatuses capable of performing radio communication are sought, and service information relating to contents of image printing services provided by image printing apparatuses so detected is received from the plurality of image printing apparatuses. Information relating to the contents of the image printing services of the detected plurality of image printing apparatuses is displayed based on the received service information. An arbitrary one of the displayed plurality of image printing apparatuses is selected by the user, and the image data reproduced from a recording medium is transmitted to the selected image printing apparatus.

This invention has as its object to integrate and simplify a communication interface, and to attain a size reduction of a camera housing and a cost reduction. To accomplish this, a digital camera transfers a control signal that controls the operation of at least one strobe device, and an image signal output from an image sensing means via a single USB cable. Upon making an image sensing operation that requires strobe emission of the strobe device, transfer of the image signal is suspended, and a control signal for the strobe device is preferentially transferred.

In a camera which obtains a still image and/or a moving image, at least a part of functions of the camera are previously restricted. To lift the restrictions, an operation restriction code (key data) is used. An externally inputted code and the operation restriction code are compared with each other, and if the input data and the operation restriction code correspond with each other, the restrictions of the functions are lifted.

In an image sensing apparatus using an image sensing device, such as a CCD, to be used by connecting to an external device, such as a computer, an operating rate of the CCD is changed in accordance with a rate at which the computer receives image signals from the image sensing apparatus. Further, when the operating rate of the CCD is changed, a proper exposure value is conjectured to obtain an image sensed at a proper exposure on the basis of operating rates of the CCD before and after the operating rate is changed, and a proper exposure value of the CCD before the operating rate is changed.

In a processor system having a CPU, a RAM, and a communication portion for external communication, the operation of the central processing unit is stopped when an IPL operation mode is selected by an operation mode selection switch. An IPL program transferred from the outside through the communication portion is then written to the RAM starting from a predetermined address, and the stoppage of the operation of the CPU is thereafter canceled. The CPU restarting the operation executes the IPL program written to the RAM by first reading the predetermined address to download a system program. Since the IPL program is transferred from the outside, the IPL program to be used can be easily changed.
