OBSERVING DEVICE AND OBSERVING METHOD

摘要

It is an object to provide an observing device and an observing method which can correct a mixed color of each component caused by concurrently receiving color light with a plurality of wavelength bands and can acquire an image with good color reproducibility. The observing device is comprised of a capsule type endoscope (2) having light emitting units (8a-8c) and an image picking-up unit (9), a receiving device (3) having an image processing unit (14), and an image display device (4) for displaying an internal image. The light emitting units (8a-8c) emit light of R, G, and B colors, respectively, and a color chart (7) reflects the light of R, G, and B colors to the image picking-up unit (9). The image picking-up unit (9) has a plurality of color filters corresponding to the light of R, G, and B colors and concurrently picks up the internal image and the chart image. The image processing unit (14) calculates a reverse matrix M<SUP>-1</SUP> of a mixed color matrix M indicative of a mixing state of color light to be received in accordance with the color filters with the other colors and, then, multiplies a receiving amount value of each unit pixel group forming the internal image picked up by the picking-up unit (9) by the reverse matrix M<SUP>-1</SUP> to carry out correction processing of the mixed color state.
