According to an aspect of the invention, an image processing apparatus includes a generating unit, a calculating unit, a receiving unit, and a changing unit. The generating unit generates a plurality of histograms of images with respect to each color based on an input image. The calculating unit calculates a plurality of first image densities of the images from the histograms. The receiving unit receives a content of image quality adjustment performed on the input image. The changing unit changes one of the histograms based on the content of the image quality adjustment. The one of the histogram corresponds to one of the images on which the image quality adjustment is performed. The calculating unit calculates a second image density corresponding to the one the images based on the one of the histogram changed by the changing unit.
The invention provides a toner for electrostatic image development, containing a toner particle and external additive particles adhered to the surface of the toner particle, each of the external additive particles being constituted of plural irreversibly coalesced primary particles.
A droplet ejection apparatus includes droplet ejection units each including a supply port and an ejection port, a common supply flow path, a common discharge flow path, supply flow paths that connect the supply port to the common supply flow path, openable mechanisms provided at the supply flow paths, discharge flow paths that connect the ejection port to the common discharge flow path, one-way valves provided at the discharge flow paths, a pressure applying unit, and a controller.

The systems and methods of this invention watermark an original data file using dimensional compression and expansion. The original data file extends along a given dimension and has portions that extend along that given dimension. The information is embedded into the data file by selectively dimensionally compressing or expanding a size of each of some or all of the portions along the given dimension, which can be space or time. The portions of the data file are selectively dimensionally expanded or compressed according to a given encoding scheme. This encoding scheme can use the kind of modification, the relationships between the type of modification between adjacent portions, or the duration or degree of compression or expansion to store a portion of the embedded information. The portions of the embedded information can be individual bits of binary or trinary information, or can be a portion of analog information.
