| 摘要 |
The invention concerns an imaging device and a method for controlling said device. The device comprises a power supply (1), matrix means for emitting or sensing an image, the array of the matrix imaging means being scanned at a scanning frequency, the power supply (1) converting a direct current input voltage (Dce) into at least a direct current output voltage (DCs) for powering the matrix imaging means (2). The power supply (1) is of the chopping type and chops the direct current input voltage (Dce) at a chopping frequency based on the scanning frequency. In the method controlling said imaging device, a useful image is preceded by an offset image and a correction based on the offset image is applied to the image.
