Abstract: A mobile terminal apparatus portable by a user includes a recording unit, a memory, an estimating unit, and an output unit. The recording unit records a sound that has been produced by another apparatus. The memory stores a cause of an unusual noise that occurs in the other apparatus and intensities of individual frequency components of the unusual noise in association with each other. The estimating unit estimates a cause of the sound that has been produced by the other apparatus, on the basis of intensities of individual frequency components of the sound recorded by the recording unit and content stored in the memory, the intensities being calculated from the sound. The output unit outputs information about the cause of the sound estimated by the estimating unit.

Abstract: An image forming apparatus includes multiple parts and a drive controller. The multiple parts are used to implement an image forming operation. The drive controller exerts control in such a manner that parts, each of the parts being possibly an abnormal-noise source, among the multiple parts are sequentially driven in predetermined order in an operating state for specifying a position at which abnormal noise is produced.

Abstract: An information processing apparatus includes a first acquiring unit, an identifying unit, and a transmitting unit. The first acquiring unit acquires image data including color values each of which denotes a corresponding one of multiple pixels in one or multiple pages. The identifying unit identifies, from the color values, color regions to which pixels constituting at least part of the multiple pixels belong in a predetermined color model. The transmitting unit transmits the number of pages in which the color regions identified by the identifying unit correspond to a predetermined color region combination.

Abstract: An information processing apparatus include an acquisition unit and a recording unit. The acquisition unit acquires, for each page, image data including a color value for each of plural pixels and information that indicates a type of an object for each of the pixels. The recording unit records a number of pages including plural pixels, a difference between the color values of which is less than a first threshold determined in advance and the types of the objects of which are different from each other.

Abstract: A line width measuring device includes an acquisition unit, an extraction unit, and a generation unit. The acquisition unit that acquires a binary image that is obtained by reading a medium having a line width sample printed thereon with an image reading device, the line width sample representing output characteristics regarding a line width of an image forming device. The extraction unit that extracts a displacement amount of steps that are repeatedly generated in an image corresponding to the line width sample in the binary image by reading the medium with the image reading device in an orientation such that the line width sample has an angle ? (0°<?<90°) with respect to a main scanning direction of image reading. The generation unit that generates line width information regarding a width of the line width sample by using the displacement amount extracted by the extraction unit.
