Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording / reproducing apparatus, and more particularly to recording in a recording apparatus image data taken in from an image input apparatus and code information data such as characters and numerical values taken in from a code data input apparatus. The present invention relates to an image recording / reproducing apparatus that calls up image data and code information data recorded in a recording apparatus from the recording apparatus and displays them on a display apparatus.

[0002]

2. Description of the Related Art Conventionally, when reproducing recorded image data in an image recording / reproducing apparatus, in order to select an image to be reproduced, it is necessary to directly check the images by checking the whole images one by one. There are provided a page-turning type in which the user looks like turning pages and a list-displaying type in which a plurality of whole reduced images obtained by reducing the whole image of the image are displayed in a list on one screen.

In the former case, that is, in the case of the page turning method, there is an advantage that individual images can be observed in detail, but when the displayed image becomes a high-definition image, the data amount of the image is drastically increased. There is a drawback that the processing speed becomes slower because of the increase.

On the other hand, in the case of the list display method, a plurality of images can be observed at one time, but the images cannot be observed in detail, and it may be difficult to distinguish similar images.
In order to overcome this drawback, a method of displaying a reduced area image obtained by reducing the characteristic area of the image in addition to the reduced overall image of the image and performing the search is disclosed in JP-A-2-1962.
It is proposed in Japanese Patent No. 375.

[0005]

However, as described above, the conventional method of using both the entire reduced image obtained by reducing the entire image of the image and the reduced region image obtained by reducing the partial region in the image search is not known. It is possible to perform both high-speed image observation by displaying a list of images and observation of detailed portions using reduced area images, but it is necessary to specify the characteristic area portion when inputting image data, which is troublesome. There is a problem of this.

Further, when a plurality of characteristic portions are scattered on the image, the area reduced image becomes large in size when it is attempted to capture all of the characteristic points in the reduced area image, which does not change much from the overall reduced image. When the display is narrowed down to one feature point, there is a problem that other feature points cannot be observed in the area reduced image.

The present invention has been made in view of the above points, does not require any special operation, has a good operability, and is capable of performing a high-speed image search by displaying a list of whole reduced images and partial images. An image recording / reproducing apparatus is provided.

[0008]

In order to achieve the above object, an image recording / reproducing apparatus according to the present invention comprises image data taken from an image input apparatus and code information data showing characters and numerical values taken from the input apparatus. And an image recording / reproducing apparatus for recording the image data and the code information data recorded on the recording apparatus from the recording apparatus and displaying on the display apparatus. An overall reduced image creating means for creating an overall reduced image in which the entire image data is reduced during recording, a partial image creating means for creating a partial image at a predetermined location having the same image size as the overall reduced image, and the entire image An image, a reduced image, and a partial image are recorded in association with the recording device,
When displaying the image data recorded in the recording device on the display device, a control for displaying the reduced image and the partial image on the display device and selecting the whole image by appropriately selecting the input means And means.

[0009]

In other words, the information indicating the characteristics of the image is often located at the center of the image. Further, some images require observation of a fine pattern, and some images should not be reduced at all. Therefore, in the image recording / reproducing apparatus of the present invention, a predetermined portion of the image, such as a central portion, has the same size as the entire reduced image without being reduced, and is automatically combined with the entire reduced image as a partial image. I try to create and record it.

As a result, it becomes possible to save the trouble of designating an area at the time of capturing an image and improve the operability. Depending on the image, characteristic regions may be scattered at a plurality of locations on the image. In that case, a plurality of arbitrary regions may be designated to create a plurality of region reduced images. This enables feature points to be recorded in any small image, and an image can be selected from the small images.

Further, an instruction may be given in advance to divide the image into a plurality of areas, and when the image is taken in, a plurality of area reduced images are automatically created and recorded together with the entire reduced image. As a result, it becomes possible to save the labor of designating an area at the time of capturing an image, improve operability, record all the characteristic points of a plurality of images in a small image, and select an image from the small images.
