  • Patent number: 4532558
    Abstract: A picture recording apparatus is capable of easily confirming the quality or recorded condition of a still picture signal stored in a memory device. The memory device includes a plurality of memory units and whether the still picture signal corresponding to one frame and stored in the memory device is "good" or "bad" is discriminated by a discriminator before the next photographing. Where the apparatus includes an erase head, if the discrimination results in "bad", the content of the corresponding memory unit is erased and the content resulting from the next photographing is stored automatically in the corresponding memory unit. If the discrimination results in "good" in the apparatus or if the apparatus has no erase head, after the discrimination the content resulting from the next photographing is automatically stored in the next memory unit.
