The utility model provides an image sensor pixel, a pixel circuit and an image sensor. In the image sensor pixel, a first pixel obtains a first optical signal, and a second pixel obtains a second optical signal; the second pixels are located at set positions of the first pixels, so that the first pixels and the second pixels are arranged in a periodic array; the first pixel and the second pixel at the set position corresponding to the first pixel form a pixel unit of the image sensor pixel; the sensitivity of the first photoelectric conversion element in the first pixel is greater than that of the second photoelectric conversion element in the second pixel, the second pixel further comprises an adjusting capacitor, and the two ends of the adjusting capacitor are coupled to a second floating diffusion point of the second pixel and a control signal so as to adjust the potential of the second floating diffusion point based on the control signal. According to the design of the utility model, the potential of the
