An image sensor includes: a pixel array including a plurality of sensing pixels each configured to convert a received light signal into an electrical signal; a readout circuit configured to convert the electrical signals into image data and output the image data; and a bad pixel correction circuit configured to: input, to a neural network, first input data comprising a first cluster bad pixel of the image data in a first direction to generate a first corrected pixel data, and flip second input data comprising a second cluster bad pixel of the image data in a second direction to generate third input data, and input, to the neural network, the third input data to generate a second corrected pixel data.

Image sensor and operating method

An electronic device includes a touch panel that includes a plurality of row touch lines and a plurality of column touch lines, a touch driver that controls the plurality of row touch lines and the plurality of column touch lines to obtain secondary biometrics including touch profile information, first indicator information, and second indicator information associated with a fingerprint of a user being in contact with the touch panel, in a fingerprint sensing mode of the electronic device, a fingerprint sensor that obtains fingerprint information about the fingerprint of the user, in the fingerprint sensing mode of the electronic device, an authentication module that performs a fingerprint matching operation and an anti-spoofing operation based on the fingerprint information and the secondary biometrics to output an authentication result, and an application processor that performs a security operation based on the authentication result.
