Image data of an image as shown in FIG. 5A is stored. First, the CPU 101 of the calculator 100 acquires image data from the digital camera 200 via the communication cable C (step S501).

Next, the CPU 101 displays an image based on the acquired image data on the display unit 105 (step S502). As a result, the display unit 105 is displayed in FIG.
An image as shown in (a) is displayed. In FIG. 5A, reference numeral 401 indicates a person who is a subject (object), and reference numeral 402 indicates a tree which is a subject (object).

[Eighth Operation Mode] The eighth operation mode of the image processing system 1 will be described below with reference to FIGS. FIG. 18 is a flowchart for explaining the eighth operation mode. First, the CPU 101 of the calculator 100
Causes the display unit 105 to individually display each of the plurality of types of image data acquired from the digital camera 200. As a result, for example, the images as shown in FIGS. 19A and 19B are individually displayed on the display unit 105. Here, the operator uses the tablet 103 to specify at least one arbitrary object in each image, and uses the input unit 102 to input the length (actual size) of the specified object in each direction. .

Next, the CPU 101 calculates the actual size of the entire image for each image data based on the actual size of the object input by the operator for each image data. That is, the CPU 101 calculates the actual area of the image displayed in the frame of the display unit 105 for each image data (step S1901).

Next, the CPU 101 determines that the ratio of the display size of each image data matches the ratio of the actual area of each image based on the image data acquired from the RAM 107 and the actual area of each image data. Then, these image data are scale-changed and displayed as a list on the screen of the display unit 105 (step S1908), and the process ends.

As a result, the display unit 105 displays, for example,
A list of images as shown in FIG. 19C is displayed. FIG. 19
In (c), it is assumed that the image 1801 and the image 1802 are designated. Here, the image 1801 corresponds to the image shown in FIG. 19A, and the image 1802 corresponds to the image shown in FIG. 19B. When these images are displayed individually, the tree 1801a included in the image shown in FIG. 19A looks larger than the tree 1802a included in the image shown in FIG. 19B. When each image is displayed in a list, as shown in FIG. 19C, the relative size ratio corresponding to the actual size of each object is known so that the tree 1802a is actually larger. You can

As described above, according to the eighth operation mode of the image processing system 1, the CPU 101 controls the CPU 101 so that the display size ratio of each image data matches the actual area ratio of each image. Since the image data of (1) are scaled and displayed on the display unit 105 as a list, the sizes of the plurality of images can be displayed as a list according to the ratio of the actual dimensions of the objects and compared.

[Ninth Mode of Operation] The ninth mode of operation of the image processing system 1 will be described below with reference to FIGS. FIG. 20 is a flow chart for explaining the ninth operation mode. First, C of the digital camera 200
The PU 212 captures an image of a subject, triggered by an operation signal from the key input unit 211, to generate image data of the subject (step S2101).

(YES), the actual area of the closed section currently displayed on the display unit 105 and the marking representing the closed section are erased (step S2112), and then the process returns to step S2107. On the other hand, when the CPU 101 determines that another closed section is not designated (step S2111; NO), the processing ends.

As described above, according to the ninth operation mode of the image processing system 1, the area of the closed section designated by the operator using the tablet 103 by the CPU 101 is based on the actual area of the image. Since the calculation result is displayed on the display unit 105 while being calculated, the actual area of an arbitrary part of the object included in the image can be known.

[Tenth Mode of Operation] The tenth mode of operation of the image processing system 1 will be described below with reference to FIGS. FIG. 22 is a flowchart for explaining the tenth operation mode. First, the digital camera 20

Accordingly, the horizontal display range of the image is expanded / contracted, and when the third axis 2401c is expanded / contracted, the display range in the depth direction of the image is expanded / contracted in accordance with the expansion / contraction (FIG. 25 (c)). It should be noted that, of these first to third axes, two or three axes can be simultaneously expanded and contracted. Here, the operator is the tablet 1
The rectangular parallelepiped 2401 can be operated again using 03.

Next, the CPU 101 causes the tablet 10
It is determined whether or not the rectangular parallelepiped 2401 has been operated again by 3, that is, whether or not there is another image size change request (step S2510). Here, the CPU 101
Detects that the rectangular parallelepiped 2401 has been operated again by the tablet 103 (step S2510; YE

01 determines that the rectangular parallelepiped 2401 has not been operated again by the tablet 103 (step S25
10; NO), and proceeds to the next step S2511.

In step S2511, the CPU 10
1 determines whether another image is selected by the operator based on the input signal from the input unit 102 (step S2511). Here, when the CPU 101 determines that another image is selected (step S2511;
(YES), the other selected image is displayed on the display unit 105 (step S2512), and then the process returns to step S2506. On the other hand, when the CPU 101 determines that another image is desired to be selected (step S251).
