Abstract: An information processing apparatus that makes it possible to obtain a result of prediction of a consumption degree (remaining amount) of a consumable at a desired timing. The information processing apparatus is capable of communicating with an image forming apparatus that forms an image using toner supplied from a toner container mounted thereon. A reception unit receives first information on a consumption amount of the toner by the image forming apparatus. A controller acquires date information on a designated date, and determines second information on a consumption amount of the toner by the designated date, based on the first information in an amount corresponding to a predetermined number of days before a certain day before the designated date.

Abstract: An image reading apparatus includes a transparent member, reading portion, a pattern, and a processor. The processor extracts a frequency component in an image of the pattern read by the reading portion in a period in which the reading portion reads an image of an original placed on the transparent member while moving in a first direction. The processor calculates a frequency component from the extracted frequency component in another position different from the position, in which the pattern is provided, with respect to the second direction crossing the first direction. The processor converts the calculated frequency component in the above-described another position into a time-series component. The processor corrects an image corresponding to the above-described another position by using the converted time-series component in the above-described another position.
