摘要:
An illumination environment reproducing system for illuminating an object (14) to be observed by an observer (15) or captured by a capturing device (16), under a desired illumination environment. The system includes an illumination environment projection device (12) for projecting a light distribution of the illumination environment as an image. A diffusion screen (13) is arranged to cover at least an upper portion of the object (14), for illuminating the object (14) by a diffusion reflection or diffusion transmission of the illumination environment projected by the projection device (12).

An image pickup element picks up an image formed by an optical system. A drive mechanism performs focus adjustment of the optical system on the basis of a signal output from the image pickup element. A storage unit stores MTF ratios corresponding to a plurality of spatial previously frequencies at each of two positions near a focal plane of the optical system in accordance with a defocus amount of the optical system, and to a predetermined value of characteristic values of the optical system. A converter converts the MTF ratio values stored in the storage unit in accordance with the characteristic value of the optical system. A first calculating unit calculates a ratio of the plurality of spatial frequency components corresponding to respective focusing states on the basis of a signal output from the image pickup element. A second calculating unit compares the calculated ratio of the spatial frequency components with the MTF ratio converted by the converter to calculate the defocus amount of the optical system. The drive mechanism drives the optical system in the axial direction in accordance with the defocus amount output from the second calculating unit and at least one of the characteristic values of the optical system.

An image storage portion 31 stores image data that is input. An outline detecting portion 32 detects an outline of tooth that is the object of color measurement in the image based on the image data. A specular reflection region detecting portion 33 detects the position of a specular reflection region in the tooth that is the object of color measurement based on the data of each pixel that constitutes the image. A rectangular region setting portion 34 sets an analysis region to become the object of analysis processing in the image based on the position of the specular reflection region that is detected by the specular reflection region detecting portion 33. In accordance with the present invention, it is possible to avoid setting an analysis region in a specular reflection region when setting an analysis region, that is the object of analysis processing of an image, in the image.

The photographing apparatus (1) includes six LEDs (6a to 6f) for emitting light with characteristics of spectroscopic distributions varied in a visible light area, a monochrome-type CCD (8) which picks-up a subject image that is illuminated by the LEDs (6a to 6f) and is formed by an image pick-up optical system (7) and which outputs an image signal, and a CPU (18) which sequentially lights-on the LEDs (6a to 6f) upon an instruction for photographing a subject spectroscopic image being input from an operating switch (14), picks-up the image by the CCD (8), and thus controls the operation for capturing 6-primary-color subject spectroscopic images. The processing apparatus (2) includes a calculating device (21) which captures the 6-primary-color subject spectroscopic images photographed by the photographing apparatus (1) to create a display signal for color reproduction at the high fidelity level, and a display (22) which displays the display signal created by the calculating device (21).
