Abstract
A two-dimensional information processing apparatus comprises a plurality of unit cell circuits arranged in a tow-dimensional matrix and each including a detector for detecting information as predetermined part of two-dimensional information, a storage circuit for storing the information detected by the detector, and a signal processing circuit for generating a pulse width modulation signal which has a pulse width corresponding to the information detected or stored, a plurality of address lines extending in a direction of columns of the matrix, and each connected to those unit cell circuits which are included in a corresponding one of the columns, a plurality of bus lines extending in a direction of rows of the matrix, and each connected to those unit cell circuits which are included in a corresponding one of the rows, means for selecting at least one of the address lines and supplying, through the selected address line, a control signal for generating a pulse width modulation signal to those unit cell circuits which are included in the selected bus line, and means for selecting at least one of the bus lines and reading, through the selected bus line, at least one pulse width modula…
