Parameter synchronization method, shooting device and movable platform

Abstract

The invention discloses a parameter synchronization method, a shooting device and a movable platform. The method comprises: sending a frame synchronization instruction to a plurality of elements in the photographing device, wherein the plurality of elements set an image frame number corresponding to a moment when the frame synchronization instruction is received as the same initial frame number and count the image frame number from the same initial frame number when a frame synchronization signal is received (S301); obtaining at least one exposure parameter required for photographing (S302); according to the effective delay duration of each exposure parameter, obtaining the exposure parameters; determining a transmission time of each exposure parameter (S303); when the transmission time ofeach exposure parameter arrives, transmitting the exposure parameter to N elements of the plurality of elements that require the exposure parameter, wherein the N elements use the at least one exposure parameter at the same image frame number (S304). And meanwhile, the generated exposure parameters take effect in the same image frame in the N elements, so that the exposure problem of the image isprevented, and the image quality is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic technology, and in particular to a parameter synchronization method, a photographing device and a movable platform. Background technique [0002] With the popularization of the shooting device, the application scenarios of the shooting device are becoming wider and wider, for example, the shooting device can be applied to drones or smart phones. Users have higher and higher requirements on the image quality captured by the shooting device. Among them, the exposure parameters are the key factors to determine the image quality. The exposure parameters include, for example, electronic shutter value, analog gain value, digital gain value, and aperture value. During the shooting process, multiple components need to cooperate to complete image acquisition. Therefore, after the body of the shooting device generates exposure parameters, the exposure parameters need to be sent to the ima...

Problems solved by technology

However, different parameters have different effective delays, which will cause the exposure parameters generated at the same time to take effect at different times, which will cause exposure problems in the captured images and affect image quality.
