  • Patent number: 11172159
    Abstract: There is provided a monitoring camera system including at least one monitoring camera and a recorder connected to the monitoring camera. The monitoring camera captures an image of an area of a monitoring target, detects a motion in a captured video of the area, associates information relating to the motion with the captured video, and transmits the associated result to the recorder. The recorder associates the captured video of the area captured by the monitoring camera and the information relating to the motion with the monitoring camera, and records the associated result. The recorder reproduces the captured video of the area on a monitor recorded in the way that a reproduction speed of the captured video in a section in which the motion is not detected on the monitor is faster than a reproduction speed of the captured video in a section in which the motion is detected, based on the information relating to the motion.

  • Patent number: 11165978
    Abstract: In order to provide an imaging device that includes an amplifier performing amplification with a plurality of gains for each signal from a pixel unit and can further reduce a noise component, an imaging device included in an imaging apparatus has the pixel unit in which unit pixels are arranged in a matrix and generates a signal voltage by photoelectric conversion. A column amplifier can amplify a photoelectrically converted signal with a plurality of gains. After an amplified signal is subjected to analog/digital conversion by a column ADC, a signal processing circuit subtracts a noise signal from a pixel signal. A noise signal read out after resetting a floating diffusion section included in the pixel unit and a pixel signal read out immediately thereafter are acquired by being multiplied by a first gain, and a pixel signal read out thereafter is acquired by being multiplied by a second gain. The first gain is set to a value larger than the second gain.
