Patent ID: 8345124

Claim:
A digital camera controlled by a control circuit comprising: an image sensor; and the control circuit for executing a series of photographing processings including subjecting an image signal obtained by an exposure processing of an imaging area of the image sensor to one or more steps of signal processing, and then recording the image signal thereby obtained on a recording medium, wherein the control circuit comprises: a recording medium initialization processing unit which performs an initialization processing of the recording medium mounted on the digital camera, and a control processing unit which performs control of operation of the recording medium initialization processing unit and the series of photographing processings, wherein the control processing unit comprising: an initialization processing starting unit which causes the recording medium initialization processing unit to start the initialization processing of the recording medium when a power of a camera body is turned on; an image recording operation presence/absence determining unit which determines presence or absence of an image recording operation by a user after the initialization processing by the recording medium initialization processing unit is started; a processing starting unit which starts the series of photographing processings when it is determined that the image recording operation by a user has been performed; an initialization processing completion determining unit which, at the time of completion of either the exposure processing or the one or more steps of signal processing after the series of photographing processings is started, suspends the series of photographing processings to determine whether or not the initialization processing by the recording medium initialization processing unit has been completed; and a processing resuming unit which resumes the series of photographing processings when it is determined that the initialization processing by the recording medium initialization processing unit has been completed wherein the processing resuming unit comprises: a recording propriety determining unit which, when it is determined that the initialization processing by the recording medium initialization processing unit has been completed, determines whether or not the image signal obtained through the one or more steps of signal processing can be recorded on the recording medium in a recording processing based on medium information of the recording medium obtained by the initialization process.
