Abstract

An image forming apparatus includes a head, a detector, and circuitry. The head forms an image on a recording medium. The detector detects a vertical movement of the recording medium and a distance to the recording medium in a vertical direction. The detector includes an optical sensor to project light to the recording medium and receive the light reflected from the recording medium. The circuitry sets a first area based on a result of detection performed by the detector. The first area is an area in which the recording medium and the head collide with each other. The circuitry retracts the head to prevent the recording medium and the head from colliding with each other, in a case where a position of the head is in the first area.

Abstract

An image-capturing system includes circuitry to receive multiple phase images for each of multiple phases. The multiple phase images include multiple first phase images captured under a first condition and one or more second phase images captured under a second condition different from the first condition, and the multiple first phase images are greater in number than the one or more second phase images. The circuitry calculates, for each of the multiple phases, a motion amount, at least, among the multiple first phase images of a same phase; performs correction on the multiple first phase images of the same phase based on the motion amount; and performs addition processing on the multiple first phase images of the same phase, so as to generate a summed phase image for each of the multiple phases.

Abstract

Systems and methods are provided for validating an autoencoder for a printing system. In one embodiment, a system stores values associated with individual features at a printing system and further stores times indicating when the values were determined at the printing system. The system also operates an autoencoder to perform time-compression upon the values and the times. Validating the autoencoder includes: determining predictive powers of the individual features prior to time-compression via partial F tests, determining predictive powers of the individual features after time-compression via partial F tests, and determining differences between the predictive powers of the individual features before time-compression and the predictive powers of the individual features after time-compression. Depending upon differences in the predictive powers, a report is generated indicating validity or invalidity of the autoencoder.

Abstract

An information processing server is communicably connected with a display apparatus and a terminal apparatus via a network. The server includes circuitry to cause the terminal apparatus to display an object based on object information including time information indicating a time at which the object was displayed by the display apparatus and a record including audio or video recorded by a device communicably connected with the terminal apparatus, generate screen information of a screen that presents, based on the time information, instruction information for playing back the object at the time indicated by the time information or the record including the audio or the video related to the object, and transmit the record, the object information, and the screen information representing the screen to the terminal apparatus.
