Abstract
The application provides a cross-row time delay integral method, apparatus and camera. The method includes obtaining a first stage integral energy in an i-th target region from an i-th row of a first integral piece domain; transferring the first stage integral energy across rows to an i-th row of a second integral piece domain; obtaining the first stage integral energy and an second stage integral energy accumulated in the i-th target region from the i-th row of the second integral piece domain, after an integration period; outputting an image of the i-th target region containing the first stage integral energy and the second stage integral energy. The application performs cross-row integration through the energy obtained by imaging, the shooting of the target can be carried out in a higher-speed environment, the method can be implemented on the existing photoelectric device, and the method has excellent imaging quality and wide applicability.
