Abstract: The present application provides a powering device, an equipment, a method, a medium, and a computer program product for image acquisition. The device includes: an energy storage circuit connected to a power supply and configured to store electric energy of the power supply; an image acquisition module connected to the energy storage circuit and configured to use the electric energy stored in the energy storage circuit for powering during image acquisition. In this way, when the image acquisition module needs a high current for image acquisition, the image acquisition module will not draw high current electric energy from the power supply, and the voltage of the power supply can be kept stable, thereby ensuring the stability of the operation of other circuit components that need to be powered by the power supply.

Abstract: A backlight control system, a control method, and a related device are provided. The backlight control system includes: a power conversion unit, configured to convert an input electrical signal into an output voltage to drive a light source; an acquisition unit, configured to acquire a cathode voltage of the light source at a timing of a completion of light source illumination; and a processing unit, connected to the acquisition unit and configured to determine feedback information used to adjust the output voltage based on a preset voltage and the cathode voltage. The cathode voltage of the light source is acquired by the acquisition unit. The processing unit determines the feedback information used to adjust the output voltage based on the preset voltage and the cathode voltage. The feedback information is beneficial for balancing backlight stability and power consumption, thereby enhancing system stability while reducing power consumption of the system.
