Zusammenfassung:	Provided are image sensors for distance measurement and camera modules. The image sensors for distance measurement include a pixel array including a plurality of unit pixels, a readout circuit configured to read out pixel signals from the pixel array in units of sub-frames and generate raw data, a preprocessing circuit configured to preprocess the raw data to generate phase data, a memory configured to store the phase data, a calibration circuit configured to generate correction data by performing a calibration operation on the phase data, an image signal processor configured to generate depth information using the correction data, and an output interface circuit configured to output depth data including the depth information in units of depth frames.
