Abstract: An time-delay-integration image sensor comprises a matrix of photosensitive pixels organized in rows and columns, a first matrix of memory cells associated with control and adding means to store accumulated brightness levels of several rows of pixels in a row of memory cells. The first memory cell matrix is provided with the control and adding means to store in its rows accumulated brightness levels of the rows of a first half of the pixel matrix. The sensor comprises a second memory cell matrix associated with the control and adding means to store accumulated brightness levels of the rows of the second half of the pixel matrix in a row of the second memory cell matrix. Means are provided for adding the levels accumulated in a row of the first memory cell matrix to the levels accumulated in a corresponding row of the second memory cell matrix.

Abstract: A time-delay-integration image sensor comprises a matrix of pixels organized in rows and columns. Each pixel comprises a first photosensitive element, a storage node and a first transfer element connected between the first photosensitive element and the storage node, Each pixel further comprises a second photosensitive element, a second transfer element connected between the second photosensitive element and the storage node, and a third transfer element connected between the storage node and the second photosensitive element of an adjacent pixel of the column. A control circuit is configured to simultaneously command the first and second transfer elements to on state and the third transfer element to off state, and, in a distinct phase, to simultaneously command the first and third transfer elements to on state and the second transfer element to off state.
