Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a still picture reproducing apparatus for recording a plurality of still pictures on a still picture recording medium and reproducing the recorded still pictures.

[0002]

2. Description of the Related Art Conventionally, a photograph, a printed matter, or the like is captured as high-resolution image data, recorded on a recording medium such as a magnetic recording medium, and the high-resolution image data is displayed on a high-resolution television monitor such as a high-definition monitor. A system that displays images is proposed. For example, JP-A-5-22682 (H04N5 /
There is a technique as shown in 76).

This prior art has a structure as shown in FIG. The operation of this prior art will be described. The image scanner 1 scans and reads a photograph or a printed matter, and the image processor 3 extracts an image of a desired area designated by the mouse 7 as image data and writes it on the optical disc by the optical disc drive 2.

For example, as shown in FIG. 8, when an image A is read from a scanner and areas A to D in the image are designated, the area designated image is enlarged and the image B is displayed on the high-definition monitor 6. Then, the image is written on the optical disc.

Then, the image is read from the recorded optical disc and the image of which the area is designated is displayed on the high-definition monitor 6. The personal computer 4 controls the image processor 3 and confirms the control operation on the personal computer monitor 5.

In this conventional technique, the following method is available as a method for designating an area by capturing with the image scanner 1.

First, in order to know the entire image to be input, it is read by a scanner. In this case, a monochrome image is input that can be processed at a higher speed than inputting a color image. Then, since the size of the original of the input image is unknown, so-called pre-scan is performed to scan the area that can be read by the scanner.

The area of the image to be input is specified by the mouse based on the prescan image, and this time, only the specified area is captured as the color input image. This is called a main scan. If the designated areas are different, the same operation is repeated.

As described above, the originals to be sequentially input are taken in by the replacement scanner, the desired area is stored in the optical disk, read from the optical disk, and displayed on the high-definition monitor.

In the system thus constructed,
Since many images are stored on the optical disc, the images must be organized. Therefore, it has been proposed to store a compressed image obtained by compressing the image captured by the main scan on an optical disc and display the compressed image as a list on the high-definition monitor 6. In order to explain this operation, the image processor 3 will be described in more detail with reference to FIG.

First, referring to FIG. 1, the image processor 3
Is an interface (IF) control circuit 8 for controlling data from the image scanner 1, an interface (IF) control circuit 9 for controlling data to the optical disc drive 2, a high-definition frame memory 10 for storing image data, and image data compression. Then, the compression / decompression control circuit 11 for decompressing, the compressed data memory 12 for storing the compressed data, the CPU 13, the mouse position recognition circuit 14 for recognizing the position of the mouse 7, and the D / for converting the data into an analog signal.
It is composed of an A converter 15.

Next, the operation will be described. First, the image data scanned by the image scanner 1 is written to the high-definition frame memory 10 via the interface (IF) circuit 8 and then supplied to the optical disc drive 2 via the interface (IF) circuit 9 for writing on the optical disc. To be done.

On the other hand, the image data of the main scan described above is compressed by the compression / decompression control circuit 11 to 1/64. Then, when the compressed image data is written in the compressed data memory 12 and the above-mentioned image data is instructed to be written in the optical disc, the compressed image data is also instructed to be written in the optical disc. These commands include command commands from the personal computer 14,
Based on this, the CPU 13 issues each control command.

These image data and compressed image data are
Since the data is stored on the optical disc with corresponding addresses, it is possible to call the image data from the compressed image data and vice versa.

Therefore, since there is compressed image data corresponding to these image data, the compressed image data is stored in the high-definition monitor 6 in the still image reproducing device of such a system.
It is also possible to display a list with.

In the list display, when there is a command from the personal computer 4, the CPU 13 sequentially reads the compressed image data of the optical disk, and the high-definition frame memory 10
In the D / A conversion unit 15.

When the frame of the compressed image data is designated by the mouse 7 from the displayed list, the D / A converter 1
The mouse position confirmation circuit 14 of the CPU 13 confirms the frame position via 5, and the corresponding image data is read from the optical disc, and the image data is read via the high-definition frame memory 10.
The / A converter 15 converts the analog signal and displays the image on the high-definition monitor 6. The D / A converter 15
Since the display control is also performed, is supplied to the CPU 13 via the D / A conversion unit 7 in order to confirm the position of the mouse 7.

By the way, desired image data is extracted from a document and displayed on the high-definition monitor 6, which has a horizontally long screen with an aspect ratio of 16: 9. For this reason, the image data is extracted so as to display the full screen of the high-definition monitor 6 in order to effectively use the powerful screen size of 16: 9.

In order to extract this image data, the frame area to be extracted must be specified. Therefore, the mouse 7 is used to select a region to be designated from the captured image. As a method therefor, there is a method of designating two points on a diagonal line with a mouse 7 as shown in FIG. 3 and determining a frame based on the two points.

However, in order to display the image data on the high-definition monitor as described above, it is necessary to set the frame size to the aspect ratio of 16: 9. Therefore, such a frame determination method has a drawback that the frame designation operation must be performed until the frames have the same aspect ratio.

[0021]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described drawbacks. When capturing an image from a document, the capture frame area is fully filled in a 16: 9 high-definition monitor with one operation. It is an object of the present invention to provide a still image reproducing device that can be displayed.

[0022]

SUMMARY OF THE INVENTION The present invention is directed to a scanner for scanning an original and converting it into prescanning and color image data, a first storage means for storing the image data, and the stored prescan. Designating means for designating an image of a desired area from the image data for use, control means for controlling the area designated by the designating means to scan the original from the original and reading it as color image data, and reading by the control means. In the still image reproducing apparatus, which comprises a recording medium for storing the color image data stored therein, and a unit for reproducing and displaying the image read from the recording medium, the designating unit designates one point of a desired image region. By specifying another point in the vertical or horizontal direction from that one point, the specified frame area has an aspect ratio of about 1
The still image reproducing apparatus is characterized in that a frame of 6: 9 is used and an area of the image is calculated to obtain an image of the area.

[0023]

According to the present invention, with the above-mentioned configuration, the frame area having the aspect ratio of 16: 9 can be automatically determined by designating only two points in the vertical or horizontal linear direction.

[0024]

Embodiments will be described below with reference to the drawings.
The hardware configuration is the same as that of FIG.
That is, a program, which is a feature of the present invention, stored in the PU 13 is added. Therefore, the feature of the present invention is shown by the flowchart shown in FIG. 2, and the embodiment of the present invention will be described below based on the hardware configuration of FIG.

Next, the operation of the work for specifying the area for extracting a desired image with the mouse 7 when the pre-scanned image is displayed on the high-definition monitor 6 will be described. First, in the present invention, in order to specify the image area, two points in the vertical or horizontal direction are determined by the mouse 7 and the frame area is determined based on the two points. Therefore, the direction to be designated first, the vertical direction or the horizontal direction, is determined (S1).

In this case, since the mouse 7 captures the horizontal axis on the screen of the high-definition monitor 6 as the X-axis and the vertical axis as the Y-axis, the horizontal axis is fixed and the Y-axis is fixed. When selected to, the X axis is fixed (the respective operation directions are as shown in FIG. 5).

Then, when the vertical direction or the horizontal direction is determined, the following operation is performed. First, the case of selecting in the horizontal direction will be described. When selected in the horizontal direction, the position of the first point, which is the point designated by the mouse 7, is set (S2). Then
The designated point is displayed on the high-definition monitor 6 (S3).

After that, the mouse 7 is used to designate the second point and the position is set (S4). Then, the second point is displayed on the high-definition monitor 6 (S5). As a result, the positions of the two points (the positions of the two points are determined by the mouse position recognition circuit 14) are set, so that the CPU 13 calculates the distance based on the position between the two points and determines the horizontal length. Is detected (S6).

Based on this, the vertical direction is calculated by calculation (S7). This calculation method is performed as follows. That is, since the frame area is set to be the same as the screen size of the high-definition monitor, the aspect ratio is 16: 9. Here, the coordinates of the first point are (X1, Y1) and the coordinates of the second point are (X2, Y1) (provided that X2> X1) as shown in the horizontal direction of FIG. If the length in the direction is Y, the aspect ratio is 16: 9 if the following relationship is satisfied. 16: 9 = (X2-X1): Y Therefore, Y to be obtained is Y = (X2-X1) * 9/16, and two points (start point and end point) on the diagonal line are determined. It becomes the start point (X1, Y1) and the end point (X2, Y).

On the other hand, if the vertical direction is selected (S1), similarly, the first point is set with the mouse 7 (S8), the first point is displayed (S9), and then the second point is set (S10). ). Then, after the second setting is displayed (S11), this time,
The length in the vertical direction is detected (S12), and the length in the horizontal direction is calculated (S13).

This calculation is performed as follows. That is, since the frame area is set to be the same as the screen size of the high-definition monitor, the aspect ratio is 16: 9. Here, the coordinates of the first point as shown in the case of the vertical direction of FIG. 6 are (X1, Y1), and the coordinates of the second point are (X1, Y2).
(Provided that Y2> Y1) and the desired horizontal length is X, the aspect ratio is 16: 9 if the following relationship is satisfied. 16: 9 = X: (Y2-Y1) Therefore, the obtained X is X = (Y2-Y1) * 16/9, and two points on the diagonal (start point and end point) are determined. It becomes the start point (X1, Y1) and the end point (X, Y2).

As a result, 1 is displayed on the high-definition monitor 6.
A frame of 6: 9 is displayed (S14). If this operation is explained on the monitor screen, it becomes a screen in which a frame is displayed as shown in FIG. Then, if the frame area is a desired area, the image display is instructed, and when the user wants to start again, the same operation is performed (S15).

When an image display is instructed, the image is displayed on the high-definition monitor. A main scan operation is performed to read the image in the frame area from the document. In this reading, the number of pixels of a high-definition still image is 1920 dots horizontally and 103 pixels vertically.
Although it is 5 dots, 1920 dots and 1040 dots in the vertical direction are used to simplify the calculation.

Therefore, assuming that the coordinates of the first point designated by the mouse are (X1, Y1) and the coordinates of the second point are (X2, Y2) (where X2> X1, Y2> Y1), become.

In the case of the horizontal direction, Y: 1040 = (X2-X1): 1920 Y = 1040 * (X2-X1) / 1920 This determines the number of pixels in the vertical direction.

In the case of the vertical direction, (Y2-Y1): 1040 = X: 1920 X = 1020 × (Y2-Y1) / 1040 Thus, the number of pixels in the horizontal direction is determined.

An image read by operating the scanner is displayed on the high-definition monitor 6 according to the number of pixels determined as described above (S16). This completes the partial image capture as shown in FIG.

[0038]

According to the present invention, by configuring as described above, the aspect ratio is automatically calculated by calculation only by designating two points between the straight lines in the vertical and horizontal directions for the frame area of the image in which the original is captured. Since the frame of 16: 9 can be displayed and the area of the frame can be actually obtained, the importing work can be simplified.
In addition, vertical and horizontal movements are instructed in advance. If the mouse moves in the horizontal direction, the Y axis is fixed, and if it is in the vertical direction, the X axis is fixed. Therefore, designation of a straight line (designation between two points) The effect that it can be easily obtained is obtained.
