| Zusammenfassung: | The invention discloses a phase focusing on-state detection method and device, and the method comprises the steps: obtaining an image matrix outputted by an image sensor, and obtaining a first brightness value of a shielding pixel point and a second brightness value of a common pixel point based on the image matrix; since the shielded pixel point is partially shielded after the phase focusing of the image sensor is started, the brightness value of the shielded pixel point is smaller than that of a common pixel point, and the first brightness difference value can be calculated according to the difference value between the first brightness value and the second brightness value, when the first brightness difference value of the shielded pixel point is determined to be greater than the first set threshold value, the first brightness difference value of the shielded pixel point is determined to be greater than the first set threshold value. According to the invention, the detection process does not need to carry o |
