Abstract
An image of an object, such as message for facsimile transmission, is acquired optically by setting photosensitive cells along a multiplicity of rows and columns of a random access memory to a given value such as 1, exposing the plurality of cells to an image so the cells change electrical values to exposure values, and after a given time, ending the effective exposure by maintaining values in the cells corresponding to the exposure content of the cells. The maintaining involves going in sequence from row to row, and in each row simultaneously reading the cells in the row and, on the basis of the reading, writing refresh values representative of the exposure values back into the read cells of the row, and repeating the row to row sequence cyclically to prevent changes in the cells due to further exposure. The refreshed data is processed by sequentially reading the refresh values of the cells of a column serially from column to column until all the values have been processed. Processing includes transmission, or compression and transmission.
