DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image capturing method suitable for performing fixed-point observation and progress observation of various objects such as animals and plants, industrial products such as electronic components, and various other objects, and particularly to an image capturing method. The present invention relates to an image photographing method suitable for always photographing these subjects in close proximity at a fixed size and a digital camera set used in the method.

[0002]

2. Description of the Related Art Recently, single-lens reflex digital cameras with a large number of pixels have become widespread, because image signals can be taken into a personal computer and displayed on a display, or images can be printed by a printer. , There is a trend to become increasingly popular in place of film cameras.

However, currently available digital cameras have a CCD image pickup device smaller than a 35 mm film camera, so that the subject is, for example, 1.5 mm in size.
The image is magnified twice or more.

For this reason, the distance (working distance) between the tip of the digital camera and the subject is longer than that of a film camera, so that close-up photography cannot be performed. For example, a small portion of the subject such as a petal can be removed. If an attempt is made to photograph these subjects at the macro position for enlarged photographing, on the contrary, the working distance becomes too short, and similarly close-up photographing becomes impossible. In particular,
If the object to be photographed extends from a small part of the subject to a major part of the subject, for example, from one petal or a total number of petals to the whole plant, commercially available digital cameras are Such wide-range subjects cannot be effectively photographed.

It is desirable to use a ring strobe or the like to irradiate the subject with uniform light for the purpose of enlarging and photographing a part of the subject. However, a commercially available ring strobe is used for a film camera. For this reason, in photographing with a digital camera, the amount of light (guide number) becomes excessive, causing halation, and close-up photographing cannot be performed using a ring strobe.

Further, when observing an object as a fixed point or observing a subject, it is preferable to describe a subject ranging from a small portion to a main portion over a wide range on substantially the same screen size. There is a drawback that a screen having a predetermined same size cannot always be obtained because the photographing is performed while adjusting the image taking into account the standard magnification.

[0007]

One problem to be solved by the present invention is to reduce the working distance of a digital camera to be as short as the working distance of a film camera, and to easily provide a close-up lens (close-up lens or magnifying lens). It is an object of the present invention to provide an image capturing method which can be attached to a camera and a digital camera set used in the method.

Another object to be solved by the present invention is to provide an image pickup device capable of taking an image without causing halation by uniformly irradiating a subject with a necessary amount of flash light in close-up shooting using a digital camera. An object of the present invention is to provide a method and a digital camera set used in the method.

Still another object of the present invention is to provide an image photographing method and an image photographing method capable of always photographing an object over a wide range from a small part to a large part with an image of almost the same size. It is to provide a digital camera set to be used.

Still another object of the present invention is to provide an image taking method capable of easily taking a picture while giving a bounce effect by flashing the entire subject from various angles, and a digital camera used in this method. It is to provide a camera set.

[0011]
