A signal processing apparatus includes a unit configured to generate noise cut data by deducting a predetermined noise value from values of respective signals constituting input data and a stochastic resonance processing unit configured to subject the noise cut data to a predetermined stochastic resonance processing. The predetermined stochastic resonance processing is processing to output, in a method of synthesizing a result of parallelly performing steps of adding new noise to the noise cut data to subject the resultant data to a binary processing, a value obtained in a case where the parallel number is infinite.

An image forming device which forms an image for color correction in the margin of a continuous recording medium such as continuous paper as appropriate without causing erroneous detection by a mark sensor at a post-processing stage. In the image forming device, a printing data generator (control section) performs: acquiring a detection criterion to detect a post-processing image for use at the post-processing stage; creating a color correction image to be used for color correction of an original image according to the detection criterion; and arranging the color correction image as an outer area image in an area other than an original image formation area in printing data.

In accordance with an embodiment, a print head includes a first light emitting element line and a second light emitting element line. The first light emitting element line and the second light emitting element line each include a plurality of light emitting elements that emit light on the basis of image data. The plurality of light emitting elements of the second light emitting element line are arranged deviated from the plurality of light emitting elements of the first light emitting element line by a certain interval in a main scanning direction.

A signal processing apparatus includes an acquisition unit that acquires input data and detection target data, a noise strength setting unit that sets a noise strength K used to a predetermined stochastic resonance processing and a stochastic resonance processing unit that performs the predetermined stochastic resonance processing and outputs processed data. The predetermined stochastic resonance processing is a processing based on a formula in which processed data J(x) is represented by I(x), the noise strength K and the threshold value T and the processed data J(x) corresponds to a result in a case where M is infinite in the following formula, $J\left(x\right)=\frac{1}{M}\underset{m=1}{\overset{M}{.Math.}}j\left(x,m\right).$ The noise strength setting unit sets the noise strength based on a function of a correlation coefficient between the result of the predetermined stochastic resonance processing and the detection target data and the noise strength K.

An image capturing unit includes a sensor unit that image-captures a predetermined area including a subject; and a reference chart unit that is arranged in the predetermined area and captured with the subject by the sensor unit.

A processor imports a 3D object, performs a 3D route slicing on the 3D object for generating printing routes respectively corresponding to printing layers of the 3D object, and performs a 2D image slicing on the 3D object for generating image files corresponding to each printing layer. The processor stores one printing route of one printing layer into a route file; stores a jetting command of the image files of the same printing layer into the route file; and stores a jetting route of the same printing layer into the route file. The processor, according to a slicing order of the multiple printing layers, stores the printing route, the jetting command, and the jetting route of each printing layer respectively into the route file, so as to complete record the route file and then outputs the route file and the multiple image files.
