摘要： An image sensor device formed in an integrated circuit (IC) having a filter device in which filter elements are arranged to provide color symmetry with respect to an optical center of the imaging array of pixels. This color symmetry ensures that any color cross-talk that occurs will be symmetrical with respect to the optical center of the imaging array and will result in a color error that is radial and easily correctable using color interpolation.

摘要： An analog sampling circuit comprising a plurality of capacitors is used to sample the reset and video sampling levels at different instants in time to obtain a plurality of respective reset sampling values and a plurality of respective video sampling values. The reset sampling values are then averaged to obtain an average reset sampling value. Likewise, the video sampling values are averaged to obtain an average video sampling value. By averaging the reset sampling values and the video sampling values over time in this manner, random telegraph noise in the reset and video sampling values is eliminated or at least substantially reduced.

摘要： An active pixel sensor (APS) image sensor comprises an array of pixel circuits corresponding to rows and columns of pixels, a plurality of amplifiers that buffer signals output by the array of pixel circuits, and a plurality of sample and hold circuits that read the buffered signals. A routing mechanism is positioned between the array of pixel circuits and the plurality of amplifiers. A controller selects a set of the pixel circuits for sampling and is configured to control the routing mechanism to couple each pixel circuit in the set to a different one of the amplifiers during a normal mode of operation and to couple each pixel circuit of a subset of pixel circuits in a first set of pixel circuits to a different amplifier of a first subset of the amplifiers, to couple each pixel circuit of a subset of pixel circuits in a second set of pixel circuits to a different amplifier of a second subset of the amplifiers, and to connect the amplifiers of the first and second subsets of amplifiers in pairs to a common one of the sample and hold circuits during a sub-sampling mode of operation.

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： A delay circuit is provided that delays the sampling signal by a selected amount in order to ensure that sampling does not occur concurrently with the occurrence of a noisy event. The noisy events on the IC tend to be periodic and occur at regular intervals. The invention allows the delay in the sampling signal to be adjusted such that sampling does not occur at the same time as the reoccurring noisy event. This ensures that the sample signals will not have noise in them resulting from the occurrence of the noisy event. In addition, the delay circuit is programmable to allow the amount of delay to be set on the fly.

The first metal layer includes a row trace and a reset trace and the second metal layer includes a column trace and a voltage supply trace. The row trace carries a signal that activates a switch for coupling the photodiode to the column trace during a readout phase and clears the voltage at the photodiode during a reset phase.
