97 results about "Dynamic resolution" patented technology

Dynamic resolution scaling (DRS) changes resolution on the fly in response to demands placed on a console's processors by what is happening on the screen. For 4K games, DRS reduces resolution from native 4K (3840 x 2160) in order to preserve factors such as frame rate and graphics quality.

System for detecting matching error of TDICCD (Time Delay and Integration Charge Coupled Device) focal plane different-speed imaging

The invention relates to a system for detecting matching error of TDICCD (Time Delay and Integration Charge Coupled Device) focal plane different-speed imaging. A dynamic target simulation device of the system is arranged in front of a parallel collimator; a zoom focusing and imaging system is arranged between the parallel collimator and a TDICCD focal plane and is composed of a group of zooming and imaging units; a control system adjusts focal distance and axial position of each zooming and imaging unit of the zoom focusing and imaging system, thus each imaging unit on the TDICCD focal plane produces target images at different speeds, moving speeds of the target images on each imaging unit on the TDICCD focal plane are calculated according to the focal distance of each zooming and imaging unit, a target rotating speed and the focal distance of the parallel collimator; and an image quick-look system analyzes dynamic target images, and a dynamic transfer function and a dynamic resolution of each imaging unit of the TDICCD focal plane are obtained by calculation. The system provided by the invention can be applied to detection on large-scale TDICCD focal plane imaging quality, image motion compensation accuracy and array different-speed image motion compensation matching accuracy.

The invention relates to a dynamic target simulator. The technical proposal adopted by the invention is as follows: a drift angle rotary bench is arranged on a work top, and the rotation axis of the drift angle rotary bench is in movable fit with a round hole in the work top; a precise turn table is fixed on the drift angle rotary bench; a dynamic target revolving drum is fixed on the precise turn table, and a plurality of target plates are fixed on the circumferential face of the dynamic target revolving drum; a drift mirror is positioned fixedly on the axial line of the drift angle rotary bench, and a first reflector is fixed on the central shaft of the drift angle rotary bench; the light from a light source irradiates the target plates, and the target plates form image on the drift mirror via the reflection of the first reflector. The dynamic target simulator can simulate a dynamic infinite high-accuracy target, provide a forward moving target for the photochronograph detection of an aero camera, and simultaneously realize the drift action of the target, thereby realizing the dynamic resolution detection of the aero camera in the lab, greatly saving development and detection cost, improving work efficiency and shortening the development cycle.
