    Abstract: Provided is a measurement device including a spectroscope, a movement mechanism configured to relatively move the spectroscope along a first direction with respect to the measurement target, and one or more processors configured to execute detecting a measurement error indicating that spectroscopic measurement processing by the spectroscope is not executed normally, and controlling the spectroscope and the movement mechanism, in which the one or more processors, when the measurement target is a plurality of color patches arranged along the first direction, cause the spectroscope to execute first measurement processing of measuring light with a specific wavelength set in advance while relatively moving the spectroscope in the first direction to acquire a measured value with respect to the specific wavelength obtained by the first measurement processing and a position of the spectroscope, and when the measurement error is detected, move the spectroscope to a position where an amount of variation of the measured value is greater than or equal to a threshold value in a second direction opposite to the first direction and then move the spectroscope in the first direction.

    Abstract: A storage unit stores a cumulative light emitting frequency or a cumulative light emitting time of a light emitting element. In a case where the cumulative light emitting frequency is greater than a predetermined light emitting frequency or the cumulative light emitting time is longer than a predetermined light emitting time, a control unit causes the light emitting element to emit light toward a living body by increasing the light emitting frequency or the light emitting time at which the light emitting element emits the light in order to acquire a light receiving result once, compared to a setting light emitting frequency or a setting light emitting time. A light receiving unit acquires information of the living body, based on a light receiving result obtained by receiving the light which is emitted toward the living body and transmitted through the living body.

    Abstract: Provided is a measurement device including a spectroscope, a movement mechanism configured to relatively move the spectroscope in one direction, and one or more processors configured to determine whether a measurement position measured by the spectroscope is moved into a color patch, in which the one or more processors cause the spectroscope to execute measurement processing for a plurality of wavelengths set in advance while relatively moving the spectroscope in the one direction, and when at least one of amounts of variation of measured values with respect to each of the plurality of wavelengths obtained in the measurement processing exceeds a first threshold value and then each of the amounts of variation of the measured values of the plurality of wavelengths falls below a second threshold value which is less than or equal to the first threshold value, determine that the measurement position is moved into the color patch.

    Abstract: An electro-optical device includes one or more control lines that include a scanning line, a data line and a pixel circuit. The pixel circuit has a drive transistor, a write-in transistor with a gate which is electrically connected to the scanning line, a light-emitting element that emits light at a brightness that depends on the size of a current that is supplied through the drive transistor, and a control line which overlaps the gate of the drive transistor when viewed from a direction that is perpendicular to a surface of a substrate on which the pixel circuit is formed is included in the one or more control lines.
