Abstract
Abstract An imaging and recording apparatus for electrically recording an optical image of a subject as an image information signal which facilitates memory access from an external device and prevents image information from being changed. Upon manipulation of a recording trigger switch (5), an image outputted from a camera signal processing circuit (17) at that time is written into a semiconductor memory (12), then subjected to data compression in a data compression circuit (21), and stored in a semiconductor memory (13). It is now assumed that an external device not illustrated is connected to a connector (14) and this external device orders taking in the image of the semiconductor memory (13). If at this time the semiconductor memory (13) is writing an image, a state detection circuit (23) detects the fact and inhibits the external device from taking in the image. Furthermore, while the external device is taking in the image of the semiconductor memory (13), the state detection circuit (23) detects this fact. Even if the recording trigger switch (5) is manipulated, an AND gate (6) turns off in response to an output of the state detection circuit and inhibits image writing into the semiconductor memory (13).
