3results about How to "Improve image capture quality" patented technology

The application discloses a camera module and electronic equipment, and belongs to the technical field of communication equipment. The camera module comprises a base frame, a photosensitive chip, a first substrate, a second substrate, a first guide column, a second guide column, a first driving mechanism and a second driving mechanism. The first guide column is arranged on the base frame. The first substrate is movably connected with the first guide column and moves along the extension direction of the first guide column. The second guide column is arranged on the first substrate. The second substrate is movably connected with the second guide column and moves along the extension direction of the second guide column. The photosensitive chip is arranged on the second substrate. The first driving mechanism is connected with the first substrate. The first driving mechanism drives the photosensitive chip to move through the first substrate and the second substrate. The second driving mechanism is connected with the second substrate. The second driving mechanism drives the photosensitive chip to move through the second substrate. The above scheme can solve the problem of poor image shooting quality of the electronic equipment.

Embodiments of the present application relate to an image acquisition device and a navigation system. The image acquisition device comprises one or more image acquisition components, each of which comprises at least a lens, an image sensor configured to convert an optical image focused by the lens into an electrical signal, a base comprising at least a cavity and a first opening portion configured to be coupled with the lens, and the cavity configured to accommodate at least the image sensor, a light supplementing device comprising one or more light emitting units configured in a predetermined area of the image acquisition device and configured to emit white light or visible light in a predetermined wavelength range, and a master control chip configured to receive the electrical signal from the image sensor. Thus, the image acquisition quality in oral surgery can be effectively improved.

The invention discloses an active and passive vibration damping device based on a piezoelectric actuator and a control method thereof, and aims to solve the problems that resonance is easy to occur and the vibration damping performance is obviously influenced by working conditions in the existing passive vibration damping method of a multi-rotor unmanned aerial vehicle, and the active vibration damping method is high in actuator stroke and energy consumption requirements, sensitive to system model errors and parameter drift and low in vibration damping performance. Therefore, the problem that the airborne camera of the multi-rotor unmanned aerial vehicle still has imaging blurring is solved. An upper platform of the device is connected with an unmanned aerial vehicle, the upper platform, a load platform, a piezoelectric actuator, a lower platform and airborne imaging equipment are coaxial from top to bottom, a spring assembly is connected with the upper platform and the lower platform, and the load platform penetrates through the lower platform through a plurality of connecting rods to be connected with connecting pieces of the airborne imaging equipment. And the multiple groups of spring assemblies and the multiple connecting rods are distributed around the piezoelectric actuator. According to the method, the piezoelectric actuator outputs reverse correction force according to the absolute acceleration of the device and the absolute acceleration of the load platform, and vibration reduction is achieved in combination with the spring assembly. The invention belongs to the technical field of vibration reduction.
