Abstract: The present invention discloses a method, a device, and a system for adjusting image display and belongs to the field of videoconferencing technologies. The method includes: receiving an image of a second conference site and an environmental parameter of the second conference site that are sent by a presence terminal of the second conference site; converting the image of the second conference site according to a pre-stored environmental parameter of a first conference site and the environmental parameter of the second conference site to obtain an image for display, wherein a conference site environmental parameter of the image for display is consistent with the environmental parameter of the first conference site; and displaying the image for display.

Abstract: The present invention relates to an analog to digital converter. The analog to digital converter includes comparing modules at multi levels, where a comparing module at each level includes a comparator and a metastable state determining unit. The comparator is configured to, when a previous-level comparing module is not in a metastable state, receive a first clock, a first input signal, and a second input signal, and compare the first input signal with the second input signal. The metastable state determining unit is configured to, when the previous-level comparing module is not in a metastable state, receive the first clock, generate a reference clock according to the first clock, and if a second clock that is output by the comparator is later than the reference clock, determine that the current-level comparing module is in a metastable state.
