The invention provides a global shutter high-dynamic range pixel and an image sensor. The global shutter high-dynamic range pixel comprises a light sensing unit, a floating diffusion node, a first charge transfer unit, a second charge transfer unit and a pixel signal output unit; the first charge transfer unit at least comprises a metal oxide semiconductor capacitor to temporarily store at least partial sensing charge transferred from the light sensing unit; the metal oxide semiconductor capacitor is switched-on/not according to the control signal, so that a grid induction potential energy trap is formed in the metal oxide semiconductor capacitor, thereby controlling the transfer of at least partial sensing charge.
