According to this invention, an electronic photographing device includes: a recording medium for recording image information corresponding to each frame photographed by panorama photographing; a predicted number of panorama-photographed frames setting device for setting information corresponding to the predicted number of photographed frames to be photographed by panoramic photographing; a number of available frames setting device for setting the number of frames which can be photographed on the basis of a capacity of the recording medium; a comparison device for comparing the number of available frames set by the number of available frames setting device with the predicted number of photographed set by the predicted number of panorama-photographed frames setting device; and a warning device for warning the user that a spare recording medium is required as a result of comparison by the comparison device if the number of available frames set by the number of available frames setting device is smaller than the predicted number of photographed frames set by the predicted number of panorama-photographed frames setting device.

Digital camera having a feature for warning a user of insufficient memory

A digital camera includes a memory card. The memory card is recorded with a plurality of image folders. Each of the image folders accommodates a plurality of image files. A CPU detects each image folder name and the number of image files included in the image folder and assigns a relation between them. If a position number of a desired image file is designated, an image folder having the desired image file is designated based on the position number and the number of image files. Thereafter, the desired image file is specified from among the image files included in the specified image folder based on the position number and the number of files. The specified image file is reproduced from the memory card and a desired image is displayed on an LCD.

A digital camera settable in a sleep mode including an ASIC for conducting data communication with a host computer connected to a USB connector, a microcomputer, a pull-up resistor connected to one of a pair of data lines, and a power source circuit. The camera further includes a power source input terminal connectable to a power source output terminal on the host computer, and an on/off switch for turning on/off the power to be supplied to the pull-up resistor. The microcomputer holds the on/off switch off when the camera is set in the sleep mode, while cancelling the sleep mode and turning on the on/off switch upon detecting the connection of the power source output terminal to the power source input terminal. This achieves a greater reduction in power consumption than conventionally, while rendering the camera adapted for a hot plug function even in the sleep mode.

A digital camera including a memory card for storing a composite image data. When an operator selects template image data and photographed image data recorded in a memory card, a CPU composites these image data with each other by using a DRAM. The CPU then compares a data amount of composite image data with a vacant capacity of the memory card. If the data amount is less than the vacant capacity, the composite image data is recorded into the memory card. Meanwhile, when the data amount is greater than the vacant capacity, the CPU displays a predetermined alarm message on an LCD. Here, if the operator attaches another memory card, the CPU again compares the data amount of the composite image data with a vacant capacity of a memory card newly attached. If the vacant capacity is sufficient, the composite image data is recorded to the same memory card.

According to this invention, an electronic photographing device in which image information corresponding to one set of images photographed by panoramic photographing can be recorded on a recording medium includes: a rotation direction setting device for setting information corresponding to a rotating direction panoramic of the electronic photographing device in the panorama photographing; a rotating direction recording device for recording information corresponding to the rotation direction set by the rotation direction setting device on the recording medium; a control device for controlling an arrangement of the set of panoramic images on the basis of the information corresponding to the rotation direction recorded on the recording medium; a display device for displaying editing information for performing predetermined image editing to the panoramic images arranged by the control device; and a control device for performing a predetermined editing operation on the basis of the editing information displayed on the display device.

A digital camera includes a CPU. When a memory card is attached to the digital camera, the CPU determines as to a format formed on the memory card. If the format is a normal format, the CPU changes the normal format to an optimal format. However, where an image file is already stored in the memory card or a directory for a file other than the image file is formed, the CPU does not change the format.

A digital camera includes a button to renew a displayed image. If an operator depresses the renewing button for 2 seconds or longer, then a continuous reproducing mode is set. If a finger is released from the renewing button, the mode is switched from the continuous reproducing mode to a normal reproducing mode. A CPU, in the continuous reproducing mode, expands thumbnail image data and magnifies the expanded data to display the thumbnail images on an LCD. In the normal reproducing mode, on the other hand, original image data is expanded, and an expanded original image is displayed on the LCD. That is, the thumbnail images are reproduced in a continuous manner during depression of a reproducing button by the operator, while the thumbnail image is turned into an original image if the operator releases his finger from the reproducing button.

A digital still camera comprising a CPU for compressing the one frame image data of a photo-shot having a constant data quantity by JPEG method into a variable length with the maximum data quantity of no more than 30 k bytes, and a flash memory for storing the compressed image data in an image region The CPU counts a number of frames of the image data already written onto the image region and the unused data capacity, obtains a remaining number of frames allowable to be photo-shot from the number of frames of the image data already written onto the image region and obtains a remaining number of frames allowable to be photo-shot from the unused data capacity of the image region and also displays either smaller one as the number of frames allowable to be photo-shot. In case of compressing the data of the photo-shot images by JPEG method and storing the data onto a data recording medium in the digital still camera, it becomes possible to calculate accurately the remaining number of frames allowable to be photo-shot.
