Abstract

Abstract An image analyzer using a standard scanning or a multiinterlaced scanning type television system includes a television circuit for producing analog video signals representative of an image to be analyzed, and a converter circuit for converting the analog video signals into digital video signals. The digital video signals may be stored in and read out of shift registers provided for respective fields and corresponding in number to the number of fields. The storage and read-out of the digital video signals may be accomplished by the use of the first and second clock pulses supplied from a pulse supply circuit to the respective shift registers. The read-out outputs of the shift registers may be combined into one frame by a gate circuit, and then processed by information processing means.
