Abstract
An image sensor includes a pixel array, an analog-to-digital converter (ADC), and a test circuit. The pixel array includes a plurality of pixels arranged in rows and columns. Each pixel generates an analog signal based on incident light. The ADC converts the analog signal to a digital signal using a counter. The test circuit receives a test code in a test mode, generates a count clock signal based on the test code, tests a counting operation of the counter according to the count clock signal, and externally outputs a test result of the counter through a test terminal.
