摘要： An image sensor device is provided that has an uncovered imaging array of pixels and a covered global reference non-imaging array of pixels. The pixel samples of the global reference non-imaging array are used to remove noise from the pixel samples of the imaging array. The control signals and control lines that are used to sample the pixels of the imaging array are separate from and independent of the control signals and control lines that are used to sample the pixels of the global reference non-imaging array of pixels. For each row of pixels of the imaging array that is sampled, the same row of pixels of the global reference non-imaging array is sampled. The global reference row has no or very few offsets or variations to ensure that noise removal is performed effectively.

摘要： An apparatus for canceling a fixed pattern noise in a CMOS image sensor includes a storage device, a fixed pattern noise operation circuit, and a fixed pattern noise canceling circuit. The storage device stores first reference fixed pattern noises operated in a vertical blank section of an (n−1)th frame. The fixed pattern noise operation circuit calculates second reference fixed pattern noises based on the first reference fixed pattern noises stored in the storage device and blank fixed pattern noises output in a vertical blank section of an n-th frame and outputs the second reference fixed pattern noises to the storage device to update the first reference fixed pattern noises to the second reference fixed pattern noises. The fixed pattern noise canceling circuit cancels active fixed pattern noises in combination signals based on the combination signals output in an active section of an (n+1)th frame and including the active fixed pattern noises and pixel signals and the second reference fixed pattern noises output from the storage device.
