An information processing device includes a storage configured to store a machine-learned model, a reception section configured to receive error information and operation information transmitted from an electronic apparatus, and a processor configured to determine whether a notification indicating error information is to be made for a user. The machine-learned model mechanically learns a condition of the notification indicating error information to be made to the user based on a data set in which the error information, the operation information, and action information indicating user action performed in response to the notification of the error information are associated with one another.

Viewing operating information of a device is controlled appropriately. A viewing control server has: an identification information manager that acquires, through a network from a manager function that manages one or more devices, device identification information unique to each device, manager identification information unique to each manager function, and customer identification information unique to each customer, and relationally stores the acquired device identification information, manager identification information, and customer identification information; a device information collector that acquires device information, which is operating information of each device, from the manager function through the network; and a viewing controller that identifies the customer identification information according to an operation from an external device, and enables viewing on an external device the device information of a device identified by the device identification information relationally stored to the identified customer identification information.

Provided herein is a user authentication method in a monitoring system that communicates with electronic equipment and monitors the electronic equipment. The monitoring system performs processes including: demanding a user to perform predetermined authentication operation that gives rise to a change in running status of the electronic equipment; acquiring, from the electronic equipment, running information that indicates the running status of the electronic equipment, the running status having changed due to the authentication operation; detecting, on a basis of the running information, that the authentication operation has been performed in response to the demand; and permitting, upon detection, the user to access the running information acquired from the electronic equipment.

An analog front-end circuit includes an analog processing circuit, an A/D converter, a calculation circuit, and a correction amount register in which a correction amount is set. The analog processing circuit includes an offset adjustment circuit that includes an offset adjustment register. The calculation circuit monitors an A/D-converted value output from the A/D converter, detects the change amount of the A/D-converted value when changing an offset adjustment value set in the offset adjustment register by 1 LSB as the correction amount, and sets the detected correction amount in the correction amount register.

An analog front-end circuit includes an analog processing circuit, an A/D converter, a calculation circuit, and a target register in which a black level target value is set. The analog processing circuit includes a clamp circuit that performs a line clamp operation, and an offset adjustment circuit. The calculation circuit monitors an A/D-converted value of a black reference pixel after the line clamp operation in a black level monitor period after a line clamp period but before an effective pixel output period, and performs a black level error correction process by writing an offset adjustment value that causes the A/D-converted value to be set at the black level target value into the offset adjustment register.

An analog front-end circuit controlling an imaging device and processing an analog image signal output from the imaging device includes: an analog processing section that receives an analog image signal from the imaging device, provides the image signal with predetermined processing, and outputs the image signal; an A/D converter that performs A/D conversion with the image signal output from the analog processing section; a transmitter circuit that receives digital image data output from the A/D converter, generates a differential signal based on the digital image data, and outputs the differential signal; and a timing generator that generates a plurality of clocks including a multiphase driving clock for driving the imaging device based on a first reference clock; the transmitter circuit including a differential amplifier circuit that generates a differential signal based on the digital image data output from the A/D converter, and outputting the differential signal generated in the differential amplifier circuit.

An analog front-end circuit includes an analog processing circuit, an A/D converter, a target register in which a lower limit target value of an input image signal is set, and a calculation circuit. The analog processing circuit includes an offset control circuit which performs offset control based on an offset control value set in an offset control register. The calculation circuit monitors the A/D-converted value in a lower limit value output period when the A/D-converted value corresponding to a lower limit value of an input range is output from the A/D converter, and sets the offset control value that causes the A/D-converted value to become closer to the lower limit target value set in the target register in the offset control register.
