An apparatus has an image sensing device, and a signal processing device for performing a first image sensing operation for making the image sensing device perform an image sensing operation in an exposure state to obtain a sensed image signal, and a second image sensing operation for making the image sensing device perform an image sensing operation in a non-exposure state to obtain a sensed image signal, and processing the sensed image signal obtained by the first image sensing operation by the sensed image signal obtained by the second image sensing operation. The signal processing device determines in accordance with the image sensing time of the first image sensing operation whether or not the second image sensing operation is performed.

A control method for an image sensing apparatus is provided with an operation unit for receiving input from a user and a communication unit for communicating with an external processing device, and having a power saving mode for stopping the supply of electrical power to at least a part of the image sensing apparatus if no input to the operation unit is performed for a predetermined time period is disclosed. The control method selects one of a plurality of operation modes including at least image sensing mode and playback mode, and controls a shift to the power saving mode depending on the selected operation mode and a state of communication with the external processing apparatus using the communication unit.

Image sensing apparatus having a power saving mode and control method therefor

In an image sensing system including at least one image sensing apparatus and at least one communication apparatus, the communication apparatus transmits the operating status of the communication apparatus to the image sensing apparatus. The image sensing apparatus determines the received operating status and displays the operating status on the display in accordance with the determination result.

Notification of operating status in image sensing system

An information signal processing apparatus according to the present invention is arranged to receive, as an input, an information signal to temporarily store therein the input information signal and to temporarily store therein management information prepared during a recording of the information signal in the recording medium, thereby recording the temporarily stored information signal and management information in the recording medium. Accordingly, it is possible to record an information signal having a large amount of information in the recording medium without lowering a recording speed and it is also possible to easily reduce the size, weight and cost of the apparatus.

A system which allows a user to transmit image data to a print laboratory technician and receive photo prints at a shop suffers cumbersome personal identification when the print laboratory technician reliably hands photo prints. To solve this problem, an electronic camera transmits image sensing data, and designation information which designates a print service which should print the image sensing data. An image gateway transmits the received image sensing data and a printing instruction for the image sensing data to the print service designated by the received designation information. Upon confirming that the print service has received the image sensing data and printing instruction, the image gateway transmits, to the electronic camera, receipt information which corresponds to the printing instruction and is used to receive a print.

Image sensing apparatus, information processing apparatus, control method for these apparatuses, image processing apparatus and method, and image processing system

An information managing system for browsing or transferring images between apparatuses is connected to a network. In this system, an information storage apparatus such as an image pickup apparatus, an information managing apparatus such as an image server, and an information processing apparatus or client computer such as a PC are interconnected by the network. The information storage apparatus uploads only related information such as an index of image data stored therein to the information managing apparatus to publicize the related information on the network. Only when the information processing apparatus for browsing the public information issues a transmission request for original information, the original information is transmitted from the information storage apparatus to the information processing apparatus.

Image information managing system

An image processing system is disclosed, wherein a demountable image pickup apparatus comprises operating means such as a keyboard, a portable computer having control means that is a CPU, image pickup means, and program storage means, which is a ROM or RAM, for storing programs to be run by the control means, and wherein imaging is effected with the image pickup apparatus mounted on an information processing apparatus.

Image processing system and information processing apparatus

A host computer is connected to a plurality of printers via an IEEE1394 bus. To make these printers print an identical image, the host computer assures a communication channel. The host computer then broadcasts print data to the printers to make them print images. In this case, the host computer starts transmission after it confirms that all the printers are ready to print and to receive print data. Upon receiving a busy response from any printer, the host computer pauses data transmission.

Image processing system and its control method

A camera includes an image sensing unit that generates unprocessed image data, an image processing unit that processes the unprocessed image data, an embedding unit that embeds first additional information in the processed image data using a digital watermarking technique, an attaching unit and a recording unit. The attaching unit attaches the first and second additional information to the unprocessed image data. The second additional information indicates to an external device that if the device generates processed image data from the unprocessed image data, it is to embed the first additional information in the processed image data using the digital watermarking technique. The recording unit records the processed image data, in which the first additional information is embedded, to a removable recording medium, in a first image recording mode, and records the unprocessed image data, to which the first and second additional information are attached, to the removable recording medium, in a second image recording mode.

Image sensing apparatus, image processing apparatus and method, and image processing system

To correct the distance between respective drums and supply image data, an image processing system using a 4-drum type color image forming apparatus requires a large-capacity image memory for temporarily storing transferred image data, and is inevitably expensive. In this invention, image data of four colors isochronously transferred via a high-speed serial interface such as an IEEE 1394 interface are respectively supplied to image processing units and image forming units via delay memories. Therefore, the time difference required for the print sheet to reach each drum can be corrected in each image forming unit to appropriately form an image at a high speed and low cost.

Image processing system, apparatus, method, and software

This invention has as its object to provide a convenient image processing apparatus which does not limit image sensing purposes. To achieve this object, an image processing apparatus has a recording medium for recording and playing back an image sensed by an image sensing unit, and an image display unit for playing back and displaying at least an image sensed before the current image. The image display unit has a display layout mode for displaying the current image sensing signal and at least the image sensed before the current image sensing signal with their partial boundary regions overlapping each other.

Image processing method and apparatus, control method therefor, and storage medium

In data transfer in isochronous mode using an IEEE1394 serial bus, the data transfer rate is guaranteed, but data transfer is disabled if the number of channels is insufficient. An already assigned channel is released by lowering the data transfer rate currently using that channel, and the released channel is assigned to new data transfer, thus allowing the new data transfer.
