Abstract
An image sensor and a camera are provided. The image sensor includes: a demodulation clock generation circuit configured to generate first to fourth demodulation clock signals respectively having first to fourth phases; a demodulation phase selection circuit configured to generate first to fourth pre-demodulation signals based on the first to fourth demodulation clock signals and a random number that changes for each of a plurality of packets; a delay circuit configured to generate a first delay signals, second delay signals, third delay signals and fourth delay signals by delaying the first to fourth pre-demodulation signals by a plurality of delay phases; and a phase mixer configured to generate first to fourth demodulation signals of which phases are changed based on an address that changes for each of the plurality of packets. The first to fourth phases have a phase difference of 90° from each other.
