Patent ID: 8130264

Claim:
A magnification observation apparatus capable of displaying an image obtained by imaging a sample to be imaged according to a set imaging condition, the magnification observation apparatus comprising: an imaging condition setting part that sets at least an exposure time as the imaging condition when imaging an original image in an imaging unit; the imaging unit that images the original image having a predetermined dynamic range, which is a ratio between minimum luminance and maximum luminance, according to the imaging condition set in the imaging condition setting part with respect to an observation position of the sample; a synthesized image generating part that generates synthesized image data that is higher in tone than a tone width of the original image by synthesizing a plurality of original images imaged under different imaging conditions at the same observation position; a display unit that displays the images imaged by the imaging unit; a tone conversion part that converts the synthesized image data generated in the synthesized image generating part to low tone image data having a tone width capable of being displayed on the display unit; and a tone data saving part that saves the low tone image data in a data region of a versatile image file, provides a high tone image region in the versatile image file to save the synthesized image data serving as a basis and saves a high tone data-attached display file including the synthesized image data in the high tone image region as metadata; and an image editing part that edits the synthesized image data by reading the metadata saved in the tone data saving part.
