Abstract: The present disclosure relates to an image processing apparatus for enabling speed-up of spectroscopic correction processing on a multispectral image and a reduction in the amount of stored data to be achieved, an image processing method, a program, and an electronic apparatus.An image processing apparatus includes an image reduction part configured to reduce a multispectral image in which an object is shot by a light dispersed in many wavelength bands, and to generate reduced images for each of the wavelength bands, and a spectroscopic correction processing part configured to perform spectroscopic correction processing of correcting a spectroscopic distribution of the reduced images for each of the wavelength bands generated by the image reduction part. Then, the processing is performed on the multispectral image shot by an imaging device including a metallic thin film filter which is provided closer to a light incident side than a photoelectric conversion device in at least some pixels and which is different in film thickness of a conductive thin film per pixel. The present technology can be applied to a shooting apparatus mounting an image sensor including a metallic thin film filter such as a plasmon filter in a hole array structure or a dot array structure, for example.

Abstract: Methods, apparatuses, systems, and storage mediums for correcting distortion of a spectrally encoded endoscopy (SEE) image are provided. A first reference pattern comprising a plurality of radial lines is scanned with an SEE spectral line to obtain a first image. Signs of a tangential shift and/or of a radial shift of the spectral line may be determined, and magnitudes of the tangential shift and of the radial shift may be computed. A second reference pattern comprising at least a circle with the SEE spectral line may be scanned to obtain a second image in a case where the radial shift is positive. The magnitude of the radial shift may be computed based on the magnitude of the tangential shift and a radius of the circle. The tangential shift and the radial shift may then be applied for correcting distortion.

Abstract: A technique for forming a two-dimensional electronic spectrum of a sample includes illuminating a line within a portion of the sample with four laser pulses; where along the entire line the difference in the arrival times between two of the laser pulses varies as a function of the position and the difference in the arrival times between the other two pulses is constant along the entire line. A spectroscopic analysis may then be performed on the resulting pulsed output signal from the illuminated line to produce a single-shot two dimensional electronic spectroscopy.
