Examples of image sensors are described herein. In an example, an image sensor may comprise an array of hybrid pixels, where each hybrid pixel includes light sensing unit and a non-volatile memory component coupled to the light sensing unit. The light sensing unit comprises a light detecting element and a charge to voltage conversion unit. The charge to voltage conversion unit is to provide an output pixel signal (VPD), based on photo-electrons generated by the light detecting element. Further, the non-volatile component when calibrated to an initial resistance state is to compress the output pixel signal (VPD) during exposure.
