| 发明名称 | Device and method for compressing an image for an image sensor | ||
| 摘要 | A device for compressing an image for an image sensor, including a module for analog decorrelation of an image for providing low-frequency coefficients and high-frequency coefficients from the image, an analog-digital coefficient converter, and a module for a differentiated analog amplification of the low-frequency coefficients and of the high-frequency coefficients, provided by the analog decorrelation module to provide modified coefficients to the converter. | ||
