The invention relates to the technical field of uniform charge transfer control of multispectral TDICMOS, in particular to a uniform charge transfer control method of a multispectral TDICMOS. The uniform charge transfer control method solves the problems that image interference exists in charge transfer of an existing multispectral TDI image sensor, spectral interference between panchromatic spectrum and multispectral spectrum exists, a plurality of groups of multiplication and division operations exist in the controller, occupied resources are large, the real-time performance is poor, different row periods are coded, each jump edge position is mapped, the operation is complex and the like in the prior art. The uniform charge transfer control method is characterized in that: the number ofminimum pixel clocks corresponding to a full-color minimum row period of a detector is taken as integer power of 2, division operation is not needed when the row period length is calculated in real time, and only high-order data needs to be intercepted after multiplication operation; and each part is partitioned, the jump edge positions of each region are counted and then encoded. By limiting thefull-color minimum row period, jump edge positions in a sensitive region are ensured to be as few as possible, and the usage amount of storage registers is reduced.
Description
technical field [0001] The invention relates to a multi-spectral TDICMOS uniform charge transfer control technology, in particular to a multi-spectral TDICMOS uniform charge transfer control method with high dynamic transfer function, low interference and low resource consumption. Background technique [0002] Compared with two-phase detectors, for multi-phase TDI image sensors, the dynamic transfer function can be greatly improved when the time length of the entire line period is evenly divided into 2 times the number of charge transfer phases. For multi-phase multi-spectral TDI image sensors, using a strict uniform charge transfer scheme, there may be interference of the charge transfer operation on the image, and spectral interference between panchromatic and multi-spectral. In addition, in the actual on-track application, the line period value range of the TDI image sensor varies greatly. In order to achieve fine image shift compensation, it is necessary to calculate the...
