ABSTRACT:
A CCD imager (10) is adaptable for recording a still image and translating the still image into a NTSC television format. An image array (12) of the imager (10) has a plurality of cells arranged in rows and columns (35-37). The cells are further divided into a plurality of fields including a first field and a second field, cells in any one row belong to a single field. A memory array (16) of the imager comprises a plurality of memory cells (128, 130, 82, 84, 174, 176, 152 and 154) including first cells (128, 82, 174, 152) for storing signals from the first field, and second cells (130, 84, 176, 54) for storing signals from the second field. A transferor (14) is operable to transfer the first field signals to the first memory cells (128, 174, 152), and also transfers the second field signals to the second memory cells (130, 84, 176, 154). A readout circuit (18-32) reads out the first field signals from the first memory cells (128, 82, 174, 152) during a first period, and reads out the second field signals from the second memory cells (130, 84, 176, 154) during a second period following the first period.
