Abstract

The communication terminal of one electronic still camera is connected to that of the other electronic still camera by means of a specific cable or infrared rays. The image data item to be transferred is selected from the image data items stored in the flash memory in the electronic still camera on the transmission side and the image data is displayed on the LCD. After determining the image data by pressing the shutter key in the key input section of one electronic still camera functioning as the master, the user specifies transmission or reception. The camera whose shutter has been pressed functions as a master and the other camera functions as a slave. In transmission, all or a given one of the image data items in the flash memory are transmitted to the slave camera. In reception, the image data is transmitted from the slave camera to the master camera. The received image data is stored in the flash memory via a DRAM.

Dependent claims

An electronic camera comprising:

an image sensor device configured to photograph a subject electronically and to produce image data including the photographed subject;
a memory configured to store the image data produced by said image-sensor device in a digital form;
a display configured to display the image data stored in said memory;
a communication device adapted to establish communication with another electronic camera;
a shutter key configured to trigger said image sensor to produce the image data, and to specify communication with said another electronic camera;
a selection key configured to select image data to be transmitted to said another electronic camera from among the image data stored in said memory;
a delete key for instructing a delete operation of image data stored in a memory of said another electronic camera;
and
a controller configured to execute control operations when:
(a) communication is established between said electronic camera and said another electronic camera via said communication device, and (b) said shutter key has been activated, wherein said control operations include:
(i) transmitting specific information for setting said another electronic camera to a reception mode, (ii) transmitting, in response to an activation of the selection key, the selected image data to said another electronic camera, and (iii) deleting, in response to an activation of the delete key, the image data stored in the memory of said another electronic camera.
