Since a failure related to an output from a sensor is not detected from an image signal and a failure of the sensor is not detected from an output from the sensor in a system including the sensor for abnormality detection, it is not possible to perform the abnormality detection and to indicate the abnormality to the outside of the system. An apparatus includes a pixel area including multiple pixels, multiple sensors, a processing unit that compares signals based on outputs from the multiple sensors with each other, an output unit that outputs information based on a result of comparison.

Apparatus, system, and movable body

A level shift circuit includes: a first transistor connected to ground and having a control terminal; a second transistor connected to the ground and having a control terminal connected to the a terminal of the first transistor; a pull-up circuit connected to a power source and also connected to the first terminal of the first transistor, and having a current mirror circuit constituted by two transistors; a third transistor having a first terminal connected to the first terminal of the first transistor, a second terminal connected to the power source, and a control terminal connected to a first terminal of the second transistor; and a fourth transistor having a first terminal connected to the first terminal of the second transistor, a second terminal connected to the power source, and a control terminal connected to the first terminal of the first transistor.
