Abstract
An image sensor includes a pixel array configured to receive a driving signal, sense a light signal reflected from an object in response to the driving signal, and generate pixel clock signals indicating delay of the driving signal; a reference clock circuit configured to generate a reference clock signal; and a time-to-analog convert circuit configured to convert delay times between the pixel clock signals and the reference clock signal into analog values.
