Abstract: An identification apparatus configured to identify a property of an object based on a spectral image includes an imaging unit configured to capture an optical spectrum dispersed by a spectroscopic unit to acquire a spectral image and a correction unit configured to correct information about a wavenumber shift corresponding to a spectral image, based on wavelength information about a wavelength of a primary light.

Abstract: An identification apparatus includes a window unit including a passage surface on an upper side configured to allow a sample supplied from a conveyance unit to slide along and pass on the passage surface, a light irradiation unit disposed below the window unit, spaced a certain distance from the passage surface, and configured to irradiate the sample with a primary light through the window unit, a light collection unit disposed below the window unit and configured to collect a secondary light from the sample through the window unit, and an acquisition unit configured to acquire identification information for identifying a property of the sample based on the secondary light collected by the light collection unit.

Abstract: Disclosed is a method of processing image data, including controlling to output multi-level value image data for reproducing a multi-level value image and bi-level value image data for reproducing a bi-level value image with respect to a predetermined area, thereby reproducing the multi-level and bi-level value images which constitute a single image.

Abstract: There is disclosed an image processing system with variable gamma characteristic, in which gamma correction is not conducted in the image processing but conducted for the output equipment when the result of image processing is released outside.

Abstract: An image processing apparatus is disclosed which includes circuitry for selectively applying variable gamma corrections to an image signal during both on-line and off-line modes of operation. In the off-line mode, the apparatus operates to simultaneously correct image signals for non-linearities produced by both an input device and an output device. In the on-line mode, correction is made for the non-linearities of the input device and a separate correction is made for the non-linearities of the output device. Such operation allows the apparatus to process linear data in the on-line mode.
