2. Description of the Related Art Conventionally, the surface condition of skin (roughness of texture, presence or absence of scaling, condition of pores, bare skin condition such as color unevenness, or cosmetic condition such as foundation) is visually diagnosed and evaluated. In order to do so, the skin surface has been enlarged and observed. In addition, skin colorimetry is also performed in order to diagnose and evaluate changes in skin color due to pigmentation such as sunburn, or to select the optimum color for makeup cosmetics such as foundation. In recent years, the surface condition including the skin color has been comprehensively judged by combining the results of the enlarged observation of the skin surface and the color measurement.

However, in the case of diagnosing and evaluating both enlarged observation and color of the skin surface, the conventional skin surface observation device and colorimetric device, which are separately configured, are used. When used, there were the following problems.

That is, by using a separate device, it becomes easy to separate the observed portion and the colorimetric portion of the skin surface, but since there is a degree of difference in the degree of unevenness on the skin,
Due to this shift, the observation result and the colorimetric result may not be used as data of the same part. Furthermore, the color of the skin cannot be said to be constant at all times because the blood flow state and the state of pigmentation change over time, so to perform accurate skin surface observation and color measurement, they should be performed simultaneously. However, it has been difficult to simultaneously perform surface observation and color measurement using separate devices. An apparatus for judging the color tone from the R, G, and B signals of the above-mentioned video camera (Japanese Patent Laid-Open No.
In Japanese Patent No. 250836 and Japanese Patent Laid-Open No. 2-206426), surface observation and color tone determination can be performed at the same time with the same device, but these devices can simply obtain relative R, G, and B intensities with respect to color tone. However, the colorimetric value cannot be accurately obtained.

Further, in general, when magnifying and observing the skin surface, the information obtained differs depending on the angle of the light irradiating the observation site on the skin surface and whether it is direct light or diffused light. It is necessary to set the irradiation system according to the purpose of observation. For example, when observing the state of pigmentation at a low magnification of about 20 times, then enlarging a specific pigmented portion to a high magnification of about 200 times and observing the texture or desquamation state of that portion, first, Good observation results can be obtained by using diffuse illumination for low-magnification observation and direct illumination from a low angle for the next high-magnification observation.

However, the conventional surface observation apparatus does not have a mechanism for changing the illumination system according to the observation magnification.
Therefore, for example, in the above example, a device for diffuse illumination used at the first low-magnification observation and a device for direct illumination from a low angle used at the next high-magnification observation are separately prepared. , They must be replaced by moving the observation device away from the observation site. Therefore, the replacement work of the lighting device becomes complicated, and there is a problem that the intended observation site is lost.

In such an illumination system, switching of the illumination method at low magnification and high magnification is performed as follows. That is, first, when the magnification obtained by the objective lens system 3 is set to a low magnification (for example, about 20 times), the light-shielding shutter 7 is linked to the cylindrical lens 5 in association with the setting of the magnification.

FIG. 6A is a perspective view of the image pickup apparatus 1 with the light shielding shutter 7 thus moved, as viewed from the tip 1a side thereof.
In the figure, 8a is the tip of the shutter support rod. At this time, of the parallel light emitted from the annular illumination 4, the light directed to the direct light transmission surface 5b is blocked, but the light transmitted through the diffusion transmission surface 5a becomes diffusion light, and the tip 1 of the image pickup apparatus 1 is formed.
The observation site is illuminated through the opening a. Therefore, the observation site is not irradiated with the direct light but only with the diffused light.

Next, when the magnification obtained by the objective lens system 3 is set to a high magnification (for example, about 200 times),
In conjunction with the setting of the magnification, the light-shielding shutter 7 moves toward the center of the opening of the tip 1a of the image pickup apparatus 1 to open an optical path through the direct light transmitting surface 5b of the cylindrical lens 5 to open the center. Close it. However, the central part is not completely closed, and a certain optical path is ensured so that a part of the reflected light from the observation site necessary for observation can reach the light receiving part. FIG. 3B is a perspective view of the image pickup apparatus 1 with the light shielding shutter 7 thus moved, as viewed from the tip 1a side thereof. At this time, of the parallel light emitted from the annular illumination 4, the light transmitted through the direct light transmitting surface 5b of the cylindrical lens 5 is reflected by the reflecting mirror 6 and has a predetermined angle with respect to the optical axis L (for example, 75 °). ) Is used to illuminate the observation site, but the diffuse transmission surface 5a
The light transmitted through is blocked. Therefore, the observation site is not irradiated with the diffused light, but is irradiated with only the direct light having a predetermined angle with respect to the optical axis. In this case, by appropriately selecting the shape of the reflecting mirror 6, direct light is emitted at a predetermined angle in one direction or in the entire circumferential direction (circular illumination), or from a plurality of predetermined different angles (polygonal illumination). You can
