Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a digital electronic still camera that uses a memory card as a recording medium for image information.

(Prior Art) Conventionally, there have been known digital electronic still cameras that record digital still images on a memory card as a recording medium, or that make the display surface of a memory card with a display device visible from outside the camera. There is.

However, these conventional digital electronic still cameras are configured so that only one memory card can be attached to the camera. Therefore, if two memory cards were to be used depending on the recorded content, it was necessary to reinstall the memory cards into the camera depending on the recorded content.

Furthermore, when it is desired to continuously manipulate a plurality of still images, for example, the number of still images that can be recorded on one memory card may be insufficient.

(Object of the Invention) Therefore, an object of the present invention is to provide a digital electronic still camera that can solve the above problems.

(Structure of the Invention) The present invention is characterized by having a plurality of mounting sections to which a memory card on which digital image information is recorded can be attached and removed, and a state in which recording is possible by selecting any mounting section among the plurality of mounting sections. A gray fabric is equipped with a selection means that can be used as a material. Further, the recordable state is that the recording on each mounting part or the recording on all the mounting parts is in the reverse direction. When a memory card is attached to one of the plurality of attachment sections i, the configuration is such that recording can be performed in that one device section.

Hereinafter, the present invention will be explained in detail based on the embodiments shown in FIGS. 1 to 32.

FIG. 1 is a perspective view of a digital electronic 2-chill camera 1 according to an embodiment of the present invention.

The digital electronic still camera l in this embodiment has two mounting holes 3.5 on the side for mounting memory cards MC, and two memory cards MC can be mounted at the same time. In addition, the installed memory card MC can be removed by pressing the two eject buttons 7.9.
can be taken out separately. When this memory card MC is connected to the digital 1 Lumiko still camera 1, it is electrically connected to the camera through terminals, and the digital image information photographed by the camera is transferred to the memory section of the memory card MC. recorded in

In addition, an optical system including a lens (not shown) is installed on the front of the digital electronic still camera 1.
There is also a release button 11 on the right side of the top surface. At the center of the top surface, there is a liquid crystal display 13 that displays information such as the number of images to be manipulated, and a mode switch 15 that sets each fullfi shadow mode, etc., and a view finder is provided at the upper left corner. .

Further, a three-position selective recording operation switch 19 is provided on the left side of the top surface. When this selection record 1 operation switch 19 is in the position of display FIJ 19a,
When video information is recorded on the memory card MC installed in the display FIJ13a, that is, the upper mounting port 3, and the selection recording operation switch 19 is in the position of the display F2JJ19b, the display F215a, that is, the memory card MC inserted in the lower mounting port 5 is recorded. When video information is recorded on the MC and the selection recording operation switch 19 is in the position of the display "." 19c,
The same video information is recorded on each of the two memory cards MC.

Furthermore, if the memory card MC is 1tirL or not installed, the main CPU 21 (see FIG. 3), which will be described later, determines the connection state between the electrical connection terminals of the memory card MC and the camera, and switches the selection recording operation switch. It is recorded on the installed memory card MC regardless of the 19th place.

In this embodiment, the case where two memory cards MC are handled has been described, but the case is not limited to this, and the same can be achieved by providing a number of mounting holes corresponding to two or more memory cards MC on the camera side. Needless to say, this applies.

Next, the operation of this embodiment will be explained with reference to FIG.

Figure 2 shows the memory card M of the digital electronic still camera 1.
12 is a flowchart showing an algorithm for setting the mounting port 3.5 of C to a state in which recording can be selectively performed on the memory card MC.

Attachment of a memory card MC is detected at the attachment port 3.5 of the digital electronic still camera l, and the number of attached cards is counted (step S1). If the number of attached cards is O at this time, the system enters a state of standby for attachment. . If the number of installed cards is 1, it is detected in step S3 which installation slot the memory card MC is installed in.

Here, when the memory card MC is inserted into the mounting port 3, the mounting port 3 is set in a recordable state (step S
5). Data is then recorded on the memory card MC by image manipulation or the like. - On the other hand, when it is detected that the device is attached to the attachment port 5, the process proceeds to step S7, and the attachment port 5 is set in a recordable state. Then, data is recorded on the memory card MC by photographing or the like. In addition, in step S1, if the number of sheets inserted is two, the process proceeds to step S9, and the operator selects in what manner the recordable state is to be set in each mounting port by using the selection recording operation switch 19. The mode is selected and set.

When it is detected that the mode of the selection recording operation switch 19 is set to 1, the process proceeds to step S5, where the mounting port 3 is set in a recordable state, and when photographic data is input, the data is recorded on the memory card.

Further, when it is detected that the mode of the selective recording operation switch 19 is set to 2, the process proceeds to step S7, the mounting port 5 is set to a recordable state, and by inputting photographic data, the data is recorded on the memory card. Ru.

Furthermore, when it is detected that the mode of the selective recording operation switch 19 is set to -, the process advances to step Sll, where both the mounting ports 3 and 5 are set to a recordable state, and the shooting data is input to the mounting ports 3 and 5. The same input data is recorded on each installed memory card MC.

FIG. 3 shows an example of the electrical configuration of the digital electronic still camera 1 and the memory card MC.

The main CPU 21 shown in FIG. 3 performs photographing in the digital electronic still camera 1 shown in FIG. 1, transfers various data including image data to the memory card MC, and other processes.
, controlled by the controller 23.

That is, the subject image photographed by the digital electronic still camera 1 passes through the optical system 25 and forms an image on the CCD 27.
The video signal obtained by photoelectric conversion is sent to the preamplifier CD5.
29. This video signal is preamplified by CD5
29. After the necessary signal processing is applied in the r-AGC preprocessing 31, the signal is converted into a digital signal in the A/D conversion circuit 33.

This digital signal is temporarily stored in the frame memory 37 via the image data compression processing circuit 35, then subjected to data compression processing and stored in the buffer memory 38 via the card interface 39. Further, this compressed digital signal 34 is recorded on the memory card MC via the card interface 39 at a transfer rate that matches the type of memory.

(Effects of the Invention) As described above, in the digital electronic still camera of the present invention, two memory cards can be installed at the same time.
You can select any memory card with the card selection switch or record on both memory cards at the same time, so you can use two memory cards depending on the recorded content without having to reinstall the card. This is useful because it can be done by simply selecting a switch.

Also, if only one school's memory card is installed,
Since it is recorded on the installed memory card regardless of the position of the card selection switch, it is useful in use because it eliminates the mistake of not recording when the installation position of the memory card and the position of the card selection switch do not match.
