Original Abstract Submitted
A ranging device includes: a processing unit configured to operate in a first mode for outputting a signal based on incident light to a first number of photoelectric conversion elements among photoelectric conversion elements and configured to operate in a second mode for outputting a signal based on incident light to a second number of photoelectric conversion elements among the photoelectric conversion elements, the second number being different from the first number; and a time conversion unit configured to generate a signal indicating a time at which light is incident on a light receiving unit based on a time count value input from a time counting unit and a signal generated in the light receiving unit. Switching from the first mode to the second mode is performed in a period from the start of light emission to the next start of light emission of a light emitting device.
