Photographing apparatus where an image is obtained by an intermittent photographing operation
A photographing apparatus comprises an imaging sensor, a power supply controller, and a moving-picture generator. The imaging sensor continuously performs imaging operations in a predetermined interval. The power supply control unit controls power supply to the imaging sensor during a waiting period that is defined as a period from the end of one imaging operation of the imaging operations to the beginning of the next imaging operation of the imaging operations. The moving-picture generator generates a moving-picture file by incorporating a plurality of still pictures, obtained by the imaging operations, into a frame composing a moving picture.
1. A photographing apparatus comprising:
an imaging sensor that continuously performs a series of imaging operations in a predetermined interval;
a controller that controls power-supply to the imaging sensor during a waiting period that is a period from the end of one imaging operation to the beginning of the next imaging operation in the series of imaging operations and generates a moving-picture file by incorporating a plurality of still pictures, which are obtained by the continuous series of imaging operations, into a frame composing a moving picture;
wherein the controller, every time the imaging operation for obtaining one still image is performed, duplicates the plurality of still pictures by a predetermined number, respectively, to obtain a plurality of duplicated still pictures, arranges the plurality of still pictures and the plurality of duplicated still pictures in the order of the imaging operations to generate the moving-picture file, and changes a frame rate of the moving-picture file by changing the predetermined number, and
wherein the controller generates the moving-picture file and duplicates the plurality of still pictures during the imaging operation for obtaining one still image.
2. The photographing apparatus according to claim 1 , wherein the controller increases the predetermined number when the frame rate is large, and reduces the predetermined number when the frame rate is small.
3. The photographing apparatus according to claim 1 , wherein the controller controls the power-supply for the moving-picture generator during the waiting period.
4. The photographing apparatus according to claim 1 , wherein the predetermined interval, a start time of the continuous series of imaging operations, and a photographing time length for the continuous series of imaging operations are settable.
5. The photographing apparatus according to claim 1 , wherein the controller duplicates the plurality of still pictures while the imaging sensor is performing the series of imaging operations.
