Provided are a pixel array and an image sensor. The pixel array includes a plurality of pixels, which are arranged in a matrix form and which convert an optical signal into an electrical signal. The pixel array includes a first pixel arranged in a first row of the pixel array and a second pixel arranged in a second row of the pixel array, wherein each of the first pixel and the second pixel includes a first memory storing a digital reset value according to internal noise, the first memory of the first pixel stores m-bit data (where m is a natural number equal to or greater than 2), and the first memory of the second pixel stores n-bit data (where n is a natural number less than m).

The present invention relates to a lens curvature variation apparatus using sensed temperature information. The lens curvature variation apparatus according to an embodiment is a lens curvature variation apparatus for varying a curvature of a liquid lens which is variable based on an applied electrical signal and includes a lens driver to apply an electrical signal to the liquid lens, a sensor unit to sense the curvature of the liquid lens formed based on the electrical signal, a temperature sensing unit to sense a temperature of a periphery of the liquid lens, and a controller to control the lens driver to form a target curvature of the liquid lens based on the sensed curvature, wherein the controller controls the lens driver to output a changed electrical signal to the liquid lens to form the target curvature, based on the sensed temperature. Thereby, the curvature of the lens can be sensed quickly and accurately using the sensed temperature information.
