Abstract
The image acquiring method and image acquiring apparatus photograph an image of a subject using stroboscopic light as external illumination. The method and apparatus compare, in terms of color change, an image acquired without using the stroboscopic light and images acquired by using a plurality of different kinds of stroboscopic light and select one kind of stroboscopic light which has the least color change to thereby finally acquire the image from among the plurality of different kinds of stroboscopic light. There is no color change due to the use of the stroboscopic light and the image having natural color reproduction can be obtained.
Claims10
An image acquiring method, in which an image of a subject is photographed using stroboscopic light as external illumination, comprising the steps of:
- comparing, in terms of color change, an image acquired without using the stroboscopic light and images acquired by using a plurality of different kinds of stroboscopic light;
- and
- selecting one kind of stroboscopic light which has the least color change from among said plurality of different kinds of stroboscopic light, thereby finally acquiring the image.
An image acquiring method, comprising the steps of:
- photographing a reference object or a subject using a plurality of different kinds of stroboscopic light as external illumination and without using stroboscopic light to acquire first images photographed respectively with said plurality of different kinds of stroboscopic light and a second image photographed without the stroboscopic light;
- determining a color change between said second image and each of said first images to obtain color changes of said first images, respectively;
- comparing said color changes of said first images photographed respectively with said plurality of different kinds of stroboscopic light;
- selecting one stroboscopic light in which said color change is least from among said plurality of different kinds of stroboscopic light;
- and
- thereby acquiring a final image of the subject.
An image acquiring apparatus for photographing an image of a subject using stroboscopic light as external illumination, comprising:
- photographing means for photographing the image of the subject;
- a stroboscopic lamp for emitting a plurality of different kinds of stroboscopic light having different colors;
- means for obtaining color change between an image acquired without using the stroboscopic light and each of images acquired using said plurality of different kinds of stroboscopic light;
- and
- stroboscopic light color selecting means for selecting one kind of stroboscopic light which has the least color change for finally acquiring the image from among said plurality of different kinds of stroboscopic light.
