Patent ID: 8654222

Claim:
An imaging device comprising: a main image sensor configured to obtain an image used for recording; a sub-image sensor configured to obtain a live view image; an input switching unit; and a signal processor, wherein the input switching unit receives a plurality of sensor outputs including an output of the main image sensor and an output of the sub-image sensor, switches the plurality of received sensor outputs in a time-division manner, and outputs time-division switched signals of the plurality of sensor outputs to the signal processor, wherein the input switching unit includes a memory, and is configured to execute a process of temporarily storing the output of the main image sensor into the memory without storing into the memory the output of the sub-image sensor being simultaneously output to the input switching unit, wherein, when the output of the main image sensor and the output of the sub-image sensor are simultaneously output to the input switching unit after an operation state of the imaging device is changed to a state in which the sub-image sensor is exposed to light from a state in which the sub-image sensor is not exposed to light, the input switching unit delays output to the signal processor of the output of the main image sensor input to the input switching unit and stored in the memory, and wherein the signal processor receives the time-division switched signals from the input switching unit, and executes signal processing on the received time-division switched signals.
