Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image input device for recording an image photographed by photoelectric conversion means such as a CCD on a recording medium such as a magnetic disk such as an electronic still camera.

[0002]

2. Description of the Related Art Conventionally, in this type of image input apparatus, when displaying the used amount of a recording medium when a captured image is recorded on the recording medium, the liquid crystal display indicates the number of captured images as shown in FIG. 21 segment display 22 is configured to display.

[0003]

However, in the above-mentioned conventional image input device, since only the number of shots is displayed,
There are the following problems. First, if the photographer himself does not know the maximum recordable number of images on the recording medium, or if the image input device is not provided with a means for acquiring the maximum number of recordable images, the remaining recordable images can be recorded. The number of shots taken by the photographer cannot be known.

Secondly, a recording medium such as a magnetic disk for recording an image has a remarkably large recording capacity as compared with a general silver salt film, and even if only the number of shots is displayed, the maximum number of shots can be taken. It is difficult for the photographer to understand how much the picture was taken.

Thirdly, in this type of image input device, normally,
The captured image data is compressed, but since the photographer can set the compression rate variably at the time of shooting, the remaining recordable number of shots differs depending on the compression rate.
It is meaningless to uniquely display only the number of shots.

In view of the above-mentioned conventional problems, it is an object of the present invention to provide an image input device capable of displaying the remaining recordable capacity of a recording medium to a photographer.

[0007]

In order to achieve the above object, the present invention provides an image input device for recording an image photographed by an image pickup means on a recording medium, the capacity of image data recorded on the recording medium or It is characterized by further comprising display means for displaying the remaining recordable capacity as a ratio to the maximum recordable capacity. Further, the present invention is characterized in that the display means displays the capacity of the image data recorded on the recording medium or the ratio of the remaining recordable capacity to the maximum recordable capacity as a bar, and further the display means. Is also used as a bar indicator for displaying the exposure state of the image pickup means, and the bar indicator indicates the capacity of the image data recorded on the recording medium or the ratio of the remaining recordable capacity to the maximum recordable capacity. It is characterized by doing.

[0008]

According to the present invention, since the capacity of the image data recorded on the recording medium or the remaining recordable capacity is displayed as a ratio to the maximum recordable capacity, the photographer can record the remaining recording capacity of the recording medium. It is possible to obtain a large capacity.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of an embodiment of an image input apparatus according to the present invention.

As shown in FIG. 1, the image input apparatus according to the present embodiment has an image pickup means 1, a compression means 2 for converting a picked-up image signal from the image pickup means 1 into a digital signal and compressing it, and a compressed image. It comprises a recording medium 3 for recording data, a control means 4 for controlling the entire apparatus, and a display means 5. The image signal photographed by the image pickup means 1 such as a CCD is converted into a digital signal, compressed by the compression means 2 and recorded on the recording medium 3. The control unit 4 controls the compression ratio of the compression unit 2, writing and reading to and from the recording medium 3, and also controls the display of the liquid crystal display 5 which is the display unit. The compression ratio of the compression unit 2 can be set to a desired value by the photographer at the time of shooting, and the control unit 4 sets the compression ratio of the compression unit 2 based on the set compression ratio. The liquid crystal display 5 displays the number of shots display section 6 for displaying the number of shots taken so far, and the ratio of the amount already recorded in the recording medium 4 to the maximum recording capacity of the recordable medium 3 in percentage. And a recording ratio display unit 7 for recording.

In such a configuration, "0" is displayed on both the number-of-photographed image display section 6 and the recording ratio display 7 in the initial state, and the image data photographed and compressed by the image pickup means 1 is recorded on the recording medium. Every time the data is recorded in No. 3, the number of images displayed on the shot number display unit 6 is incremented by one, and the display ratio of the recording ratio display unit 7 is increased according to the compression ratio. The display ratio of the recording ratio display unit 7 can be calculated by calculation based on the compression ratio, but can be easily calculated by referring to the address of the recording medium 3 on which the image data is recorded.

Therefore, according to the above embodiment, since the number of shots and the recorded capacity of the recording medium 3 are displayed by the shot number display section 6 and the recording ratio display section 7, respectively, a large capacity recording medium 3 can be used. Even if the compression ratio differs for each shooting, the photographer can know the number of shots up to now and the number of remaining recordable shots of the recording medium 3.

Instead of displaying the recorded capacity of the recording medium 3, the remaining recordable capacity of the recording medium 3 may be displayed in proportion or in number. In this case, the number of shots that can be taken is
The number of uncompressed sheets, which minimizes the number of sheets, may be displayed, or the number of sheets may be displayed according to the degree of compression rate at the present time.

2 to 4 show display screens according to the second embodiment. As shown in FIG. 2, the liquid crystal display 11 has one segment display section 12 for selectively displaying the number of captured images and the recorded capacity of the recording medium 3. The display content is based on the switching operation of the operation section. It is switched by the control means 3.
When displaying the ratio of the recorded capacity, as shown in FIG. 3, “%” indicating the ratio should be displayed together, and when displaying the number of shots, only the numbers should be displayed as shown in FIG. As a result, the one segment display unit 12 can be displayed so that the photographer can easily understand.

Here, when a large capacity recording medium 3 is used, when the remaining number of shootable images is large, the photographer needs information of a ratio higher than the remaining number of shootable images, and on the other hand, the remaining number of shootable images is required. When the number is small, information on the remaining number of recordable images is required rather than the ratio. Therefore,
In the second embodiment, one segment display unit 12 automatically displays the ratio when the number of remaining shootable images is large, and selectively displays the number when the remaining shootable number is small. It may be configured to be switchable.

Next, a third embodiment will be described with reference to FIGS. The bar display unit 13 shown in FIG. 5 displays the exposure state during manual shooting. In this display example, the manually set exposure is 1 EV relative to the proper exposure.
It shows that it is Anda. Then, the ratio is displayed on one segment display unit 12. On the other hand, in the automatic exposure mode, as shown in FIG.
Is the ratio of the recorded capacity of the recording medium 3 (20% in this example).
%) Is displayed, and the number of shots is displayed on one segment display unit 12.

Also in the third embodiment, similarly, the bar display unit 1 for displaying the exposure state at the time of manual photographing.
3, the ratio is displayed on the bar display unit 13 and the number of shots is displayed on the segment display unit 12 in the automatic exposure mode, so that the photographer can display the image easily.

Next, a fourth embodiment will be described with reference to FIGS. 7 and 8. The display unit 13a is configured so that the photographer can confirm it by visually observing the inside of the fan of the image pickup means 1. The display content is the bar display unit 1 of the third embodiment.
3 is almost the same. That is, the bar display unit 13a shown in FIG. 7 displays the exposure state during manual shooting,
This display example shows that the manually set exposure is 1 EV under the proper exposure. On the other hand,
In the automatic exposure mode, as shown in FIG.
a is the ratio of the recorded capacity of the recording medium 3 (50 in this example).
%) Is displayed.

Therefore, according to the fourth embodiment,
Bar display 13a in the founder in the automatic exposure mode
Since the ratio of the recorded capacity of the recording medium 3 is displayed, the photographer can visually and easily understand the ratio of the recorded capacity of the recording medium 3 while performing a shooting operation.

[0020]

As described above, according to the present invention, in the image input apparatus for recording the image photographed by the image pickup means on the recording medium, the capacity of the image data recorded on the recording medium or the remaining recordable data can be recorded. Since the display means for displaying the capacity in proportion to the maximum recordable capacity is provided, the remaining recordable capacity of the recording medium can be displayed to the photographer.
