Note that the same applies to the disk 9 and the IC card 10 as the recording medium, so the case of the disk 9 will be described below.

The image capturing is started by an image capturing instruction from the operation unit 4, and as shown in FIG. 2, at the time of image capturing, the CPU 1 reduces the number of pixels by a predetermined procedure from the original image input from the input unit 5 to reduce the reduced image. It is created and recorded on the disk 9 with the imaging time added to the reduced image and the original image. In the case of this device,
Both a still image and a moving image can be captured according to an instruction from the operation unit 4. When the original image is a still image, one reduced image corresponding to the original image is created. If the original image is a moving image, it is composed of a time series of still images, so a plurality of reduced images corresponding to each are created. At the time of imaging, L
The CD display 7 is used as an imaging monitor.

FIG. 3 shows the file structure of the disk 9 on which recording has been performed. From the inner peripheral side to the outer peripheral side of the disk 9, a T in which position information of each file is collectively recorded.
An OC (Table of Contents) 31, a time stamp DB (database) file 32 in which an identifier for distinguishing between a still image and a moving image is recorded, a reduced image data file 33 in which a reduced image created from an original image is recorded, It comprises an original image data file 34 in which an original image of a still image or a moving image is recorded, and an audio data file 35 in which audio data inputted from the microphone 11 is recorded.

FIG. 4 shows a time stamp DB file 32.
Is shown. This time stamp DB file 32
Is composed of a header and data, and the number of time stamps (N) and time stamp information are recorded in the data. The time stamp information includes a time stamp number assigned in the image capturing order, an image number indicating a number for each area, a time stamp indicating an image capturing time assigned by the CPU 1, and the presence or absence of character data input by the operation unit 4. It comprises a file name 41 as an identifier, an index number 42 as an identifier for distinguishing a still image or a moving image, and an audio data number 43 as an identifier indicating the presence or absence of audio data. The audio data number 43 is the address of the audio data added to the original image, and contains 00h as the audio data number when no audio data is added.

In the present embodiment, the number of indexes 42 is the number of reduced images. Number of index 42
Is one for a still image, and two or more corresponding to the number of time-series reduced images for a moving image. The number of original images may be used as the number of indexes, but the optical head of the disk drive 8 accesses from the inner circumference side during image reproduction, and it is preferable to use a reduced image closer to the TOC 31 because high-speed access is possible. .

The display of the recorded contents of the disk 9 is performed by the operation unit 4.
CPU 1 sends the TOC of disk 9
The optical head of the disk drive 8 accesses the time stamp DB file 31 and the time stamp DB file 32, reads out the index number 42, and reads 1 or 2
By discriminating the above, a still image or a moving image is distinguished, and the image is output to the LCD display 7 in a display mode shown in FIG.

In FIG. 5, a moving image and a still image are displayed at predetermined indexing time units (year, month, day, and day in the present embodiment) based on the time stamp and at a length corresponding to the index number 42, that is, the number of captured images. This is performed in a different display mode. It is not necessary to display the display length for moving images and the display length for still images on the same time scale.For moving images, the number of shot images is usually large, so the time scale is compressed and displayed compared to still images. It is better to see it. Although the unit of the predetermined imaging time of the moving image is not particularly limited, it is preferable to use a time at which a series of imaging is started.

Next, the display mode of FIG. 5 will be described with reference to the flowchart of FIG. Here, it is assumed that the upper left of the screen of the LCD display 7 is (x, y) = (0, 0). In the flowchart of FIG. 6, XA, XB, YA, Y
B and XT are constants.

First, in step S1, the CPU 1 executes
The time stamp number n and the coordinates (x,
y), the time stamp T (0) is initialized. Then C
PU1 determines the time stamp T in step S2.
(N) is the time stamp T (n) immediately before T (n).
A comparison is made to see if it is equal to -1). If YES, the process jumps to step S5. If NO, the contents of the time stamp T (n) (year.
Moon. Day) on the LCD display 7 at coordinates (x, y) =
(0, y + YB). Here, since the time stamp is displayed in the length of XT, the CPU 1 determines in step S
At 4, the value of x is updated to x + XT.

In the next step S5, the CPU 1 determines whether or not I (n) of the index number 42 is one. If YES, in step S6, the image is determined to be a still image, and points (x, y) and (x + XA, y + Y
A rectangle having the diagonal A) is displayed on the LCD display 7 in red. Further, in step S7, the CPU 1
The coordinates (x, y) are represented by the x-coordinate NX of the n-th number representation figure.
(N), and recorded as the y coordinate NY (n). Next, in step S8, since the x coordinate increases by the length XA of the displayed figure, the coordinate x is updated to x + XA, and step S8 is performed.
Proceed to 12.

If the index number I (n) is 2 or more in step S5, in step S9, the CPU 1 determines that the image is a moving image, and points (x, y).
And a rectangle having a point (x + XB × I (n), y + YA) as a diagonal is painted in blue and displayed on the LCD display 7. In step S10, the CPU 1 converts the coordinates (x, y) into the x-coordinate NX of the n-th number representation figure.
(N), and recorded as the y coordinate NY (n). Further, in step S11, since the x coordinate increases by the length of the displayed figure, the coordinate x is updated to x + XB × I (n), and the process proceeds to step S12.

In step S12, the CPU 1 compares the time stamp number n with the total number N of time stamps.
One is added to the next value of n, and the process returns to step S2 again to repeat the above processing. If the time stamp number n is equal to the total number N of time stamps, the process ends. In this embodiment, all the images corresponding to the total number N of the time stamps are displayed at a glance, but a part of the images may be displayed.

In this embodiment, the data is output to the LCD display 7 in response to a display instruction from the operation unit 4. However, when the disk 9 is loaded in the disk drive 8, the loading is performed by the CPU.
1 may be detected and output to the LCD display 7 in the above-described display mode. In this way, when the disc 9 is loaded, the contents of the disc 9 can be automatically recognized immediately, which is desirable in terms of convenience. Also, in the present embodiment, a rectangular figure and the color of the figure are used to distinguish between a moving image and a still image, a moving image displays a series of images in one rectangular figure, Displayed in a shape. There is no particular limitation as long as the moving image and the still image can be distinguished by the display form, but other forms include shapes such as circles and triangles,
Outline drawing type of figure such as thickness and dotted line, figure size,
A drawing type in a figure area such as a halfton, a diagonal line, or a wavy shape may be used.

Next, the operation of performing an image search in the state displayed as shown in FIG. 5 will be described. At the time of search, the coordinates are input by specifying the coordinates (gaze point) at which the user wants to search for an image on the display screen of the LCD display 7 using the operation unit 4, and the coordinates are input.
As shown in, the content of the still image or video near the point of interest is
It is displayed on the LCD display 7 as frame-by-frame advance of the reduced image, and a search can be performed. In the present embodiment, when the point of interest is input, the reduced image data file 33 is accessed to reproduce and display the reduced image. However, the original image data file 34 is accessed to reproduce the original image. Is also good. In the present embodiment, since the reduced image data file 33 is adjacent to the time stamp DB file 32, displaying a reduced image is desirable because it can be displayed at a higher speed.

The display operation of FIG. 7 will be described with reference to the flowchart of FIG. In the flowchart of FIG.
C, XD, YC, and YD are constants.

First, in step S1, the user uses the operation unit 4 to input arbitrary coordinates (xx, yy) as gazing point coordinates. In step S2, the CPU 1 initializes the time stamp number n as 1.

Next, in step S3, a comparison is made as to whether or not the x coordinate NX (n) of the n-th number representation figure recorded in steps S7 and S10 in FIG. 6 is close to the gazing point x coordinate xx. If YES, the same processing is performed for the y coordinate in step S4. If YES also for the gazing point y coordinate, the CPU 1 determines that the gazing point (xx, yy) is close to the display coordinates of the n-th number representation figure, and proceeds to step S5. In step S5, the CPU 1 displays the n-th reduced image at the coordinates (x + XD, y + YD) on the LCD display 7, and ends the display processing.

If NO in steps S3 and S4, it is determined in step S6 whether the time stamp number n is equal to the total number N of time stamps.
If YES, the process ends. If NO,
In step S7, the next time stamp number n + 1 is read out, and the process returns to step S3 again to repeat the above processing.
In the present embodiment, the search is performed using the total number of time stamps N.
However, it may be compared with the number of time stamps in a partial area.

Next, FIG. 9 shows another display form of FIG. 5 according to the presence or absence of voice data or character data. FIG.
FIG. 9A shows a display mode in the case where there is no audio data and no character data in both the moving image and the still image. FIG. FIG. 9C shows a display mode in a case where character data is present in the left moving image portion and there is no audio data, and FIG. 9D shows a character data in the left moving image portion. The display form when there is also audio data is shown. In this way, the display forms can be made different by realizing the presence or absence of the contents of the file name 41 and the audio data number 43 of the time stamp DB file by the CPU 1, and a more intuitive display and search can be performed. .

In the above-described embodiment, a case has been described in which the present invention is applied to an electronic camera capable of performing recording and reproduction. However, the above-described display and retrieval can be realized by a computer as a display device or a retrieval device. Further, a program having a function of performing the above-described display and search may be recorded on a recording medium such as a floppy disk or a CDROM, and may be appropriately installed and used.

[0034]

As described above, according to the image input / output device of the present invention, the image is displayed in a different display mode at a length corresponding to the number of still images and moving images taken for each predetermined imaging time unit. The contents of the recording medium can be intuitively grasped. Further, when the user wants to see in more detail, a corresponding image can be displayed only by specifying coordinates on an arbitrary screen.
