Abstract: A determination unit determines whether there is a damaged pixel in a range where a predetermined saturated pixel is detected from thermal image data acquired by capturing an image of a shutter having a uniform temperature with a sensor in a state where incidence of light on the sensor is blocked by the shutter. The shutter control unit closes the shutter when the predetermined saturated pixel is detected, and when there is no damaged pixel in the thermal image data captured when the shutter is closed, performs control to open the shutter immediately or after a lapse of a predetermined period of time that is determined in advance as a maximum time required for detection processing of the predetermined saturated pixel, or when there is a damaged pixel, performs control to open the shutter after a lapse of a time in which recovery of the damaged pixel is expected.

Abstract: To provide earphones and an earphone system each adapted to prevent loss of the earphones. An earphone according to an embodiment of the present disclosure includes a light emission unit a detection unit and a light emission control unit. The light emission unit is configured to emit light. The detection unit is configured to detect that the earphone has been dropped. The light emission control unit is configured to control the light emission unit so that it emits light when the detection unit detects that the earphone has been dropped.

Abstract: In an image processing apparatus, a first correction unit corrects imaging data acquired from an infrared imaging device, based on a first correction table, and outputs first corrected data. A second correction unit generates a second correction table for the imaging data in a state in which a shutter is closed, and outputs second corrected data based on the second correction table. A saturated region detection unit detects a saturated region in the imaging data. A shutter control unit performs closing control for the shutter, based on a result of detection of the saturated region. An abnormal pixel detection unit detects whether or not the imaging data acquired in the state in which the shutter is closed includes an abnormal pixel. A selection unit selects and outputs either the first corrected data or the second corrected data in accordance with a result of detection by the abnormal pixel detection unit.
