Provided is an image forming apparatus that speeds up the performance in the auto color mode. A document reading unit reads a document and outputs image data. A document determination unit temporarily determines the document as a monochrome document when the ratio of the color components of the document is equal to or less than the monochrome threshold value at a specific timing after the document reading unit starts reading the document. An image processing unit performs monochrome image processing on the image data. A document determination unit determines that the document is a color document when the ratio of the color components of the image data is equal to or more than the color threshold value while the image processing for the monochrome document is being performed.

An image processing apparatus for converting color data into gray data extracts an object included in the color data in a page, and determines, based on color information and position information on a first object and a second object extracted, whether at least one of the first object and the second object is to be a target of conversion of a color value of the color data into a gray value with improved discriminability. The image processing apparatus controls to convert the color value of the object into a gray value by a conversion targeting all color values, or into a gray value with the improved discriminability, based on the determination whether or not to be the target of conversion.

An image reading device includes a housing including a support that supports a document, an opening and closing (O/C) member supported to rotate around a rotary shaft between an open position at which a top surface of the support is exposed and a closed position at which the top surface is covered by the O/C member, a reading member included in the O/C member to read the document, a processing unit included in the housing to process information read by the reading member, a connecting member electrically connecting the reading member and the processing unit, and a protective member whose first end is rotatably supported by the O/C member and that accommodates the connecting member in its internal space while being supported in a state of hanging from the O/C member and in a state where its second end is supported while not being constrained with respect to the housing.

Systems and methods for replacing cells of an image based on some pre-determined metric are described herein. For example, systems and methods described herein may improve the functioning of a standard imaging system. For example, the systems and methods described herein may be used to post-process existing images in an imaging system based on one or more pre-determined metrics and improve the halftone images according to those pre-determined metrics.

An image processing apparatus has a stochastic resonance processing unit executing a stochastic resonance processing to obtain a result. The result corresponds to a result that is calculated in a case where each of a plurality of pixel signals constituting reading image data is added noise and subjected to a binary processing and a plurality of results obtained by parallelly performing above step are synthesized and the parallel number is infinite. The stochastic resonance processing unit sets, with regard to a pixel signal as a processing target among the plurality of pixel signals, at least one of a strength of the noise and a threshold value used for the binary processing based on a pixel signal of the input image data corresponding to the pixel signal.
