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.

Identification apparatus and identification method

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. Also disclosed is an interface system including a multi-level converter for converting the multi-level value image data into bi-level value image data and vice versa, a resolution converter operated in synchronism with the multi-level converter to convert the resolution of the multi-level value image data, an area data memory for storing area data corresponding to an instruction input representing a multi-level or bi-level value image area, and an output device for selecting the multi-level value image data from the resolution converter or the multi-level value image data from the multi-level converter on the basis of the area data and for outputting selected data to the image output device.

Image data processing using bi-level and multi-level value data

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.

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.
