A lighting unit has a plurality of light sources that emits excitation light having relative spectral distributions different from each other. An imaging unit simultaneously captures an image of fluorescent light emitted from the subject by the excitation light and an image of reflected light obtained by reflecting the excitation light by the subject, to generate a captured image. The arithmetic unit calculates a relative spectral distribution of the fluorescent light emitted from the subject by using the information about the relative spectral distribution of the reflected light for each of the plurality of light sources stored in the memory and the captured image for each of the plurality of light sources generated by the imaging unit.

Imaging device and image processing method

Image processing device is image processing device that uses a plurality of images respectively having focusing positions different from each other to calculate distance information to a subject, and includes frequency converter, amplitude extractor, and distance information calculator. Frequency converter converts the plurality of images into frequency. Amplitude extractor extracts an amplitude component out of a phase component and the amplitude component of a coefficient obtained by converting the plurality of images into frequency. Distance information calculator calculates the distance information, by using lens blur data and only the amplitude component extracted by amplitude extractor out of the phase component and the amplitude component of the coefficient.

Image processing device and image processing method for calculating distance information to a subject

In exemplary implements of this invention, a lens and sensor of a camera are intentionally destabilized (i.e., shifted relative to the scene being imaged) in order to create defocus effects. That is, actuators in a camera move a lens and a sensor, relative to the scene being imaged, while the camera takes a photograph. This motion simulates a larger aperture size (shallower depth of field). Thus, by translating a lens and a sensor while taking a photo, a camera with a small aperture (such as a cell phone or small point and shoot camera) may simulate the shallow DOF that can be achieved with a professional SLR camera. This invention may be implemented in such a way that programmable defocus effects may be achieved. Also, approximately depth-invariant defocus blur size may be achieved over a range of depths, in some embodiments of this invention.

In an illustrative implementation of this invention, an optical pattern that encodes binary data is printed on a transparency. For example, the pattern may comprise data matrix codes. A lenslet is placed at a distance equal to its focal length from the optical pattern, and thus collimates light from the optical pattern. The collimated light travels to a conventional camera. For example, the camera may be meters distant. The camera takes a photograph of the optical pattern at a time that the camera is not focused on the scene that it is imaging, but instead is focused at infinity. Because the light is collimated, however, a focused image is captured at the camera's focal plane. The binary data in the pattern may include information regarding the object to which the optical pattern is affixed and information from which the camera's pose may be calculated.
