Photography device and photography processing method
A photography device and photography processing method which are capable of image-recording and display without a time lag therebetween when photography is instructed. A delay duration detection section acquires, via an A/D converter, image data obtained by photography by an image capture device, also acquires image data of an image frame which is shown at a display, and detects a number of frames by which the sets of image data are separated, to serve as a delay duration (corresponding to a time lag from operation of a shutter button until display at the display). Image data in an amount corresponding to the delay duration is stored at a temporary storage memory and, when the shutter button is fully pressed, an image frame counted back by the delay duration is selected from the image frames stored in the temporary storage memory, and is both recorded and shown at the display.
1 . A photography device comprising:
an image capture device, which acquires image data representing a subject image by photographing the subject image;
an instruction section for instructing photography;
a display section, which implements display on the basis of the image data acquired by the image capture device;
an acquisition section which acquires a delay duration, which is the duration of the delay from acquisition of the image data by the image capture device until the display section displays a corresponding image;
a storage section, which stores the image data which the image capture device acquires; and
a selection section which, at a time at which photography is instructed by the instruction section, selects, from the image data stored at the storage section, image data that corresponds to a time previous to the time at which photography is instructed by the delay duration acquired by the acquisition section.
2 . The photography device of claim 1 , further comprising a compression section, which compresses the image data acquired by the image capture device, wherein the storage section stores the image data which has been compressed by the compression section.
3 . The photography device of claim 2 , further comprising:
an external storage section, which stores the image data which the image capture device acquires; and
a storage selection section, which selects a storage destination for the image data.
4 . The photography device of claim 1 , further comprising:
an external storage section, which stores the image data which the image capture device acquires; and
a storage selection section, which selects a storage destination for the image data.
5 . The photography device of claim 1 , further comprising a control section, which controls the display section so as to implement display on the basis of the image data selected by the selection section and which controls such that the image data selected by the selection section is recorded to a recording medium.
6 . The photography device of claim 1 , wherein the storage section stores the image data in an amount corresponding to at least the delay duration acquired by the acquisition section.
7 . The photography device of claim 1 , wherein the acquisition section comprises at least one of a detection section, which detects the delay duration, and a delay duration storage section, which stores a pre-specified delay duration, and the acquisition section acquires the delay duration from one of the detection section and the delay duration storage section.
8 . A photography processing method comprising:
an image capture step, for acquiring image data representing a subject image by photographing the subject image;
a display step, for implementing display on the basis of the image data acquired by the image capture step;
an acquisition step, for acquiring a delay duration, which is the duration of the delay from acquisition of the image data in the image capture step until a corresponding image is displayed in the display step;
a storage step, for storing the image data acquired by the image capture step; and
a selection step of, at a time at which photography is instructed, selecting, from the image data stored by the storage step, image data that corresponds to a time previous to the time at which photography is instructed by the delay duration acquired in the acquisition step.
9 . The photography processing method of claim 8 , further comprising a compression step for compressing the image data acquired in the image capture step, wherein the storage step includes storing the image data which has been compressed in the compression step.
10 . The photography processing method of claim 9 , further comprising a storage selection step of selecting a storage destination, which stores the image data in the storage step.
11 . The photography processing method of claim 8 , further comprising a storage selection step of selecting a storage destination, which stores the image data in the storage step.
12 . The photography processing method of claim 8 , further comprising a control step, for controlling in the display step such that display is implemented on the basis of the image data selected in the selection step and for controlling such that the image data selected in the selection step is recorded to a recording medium.
13 . The photography processing method of claim 8 , wherein the storage step includes storing the image data in an amount corresponding to at least the delay duration acquired by the acquisition step.
14 . The photography processing method of claim 8 , wherein the acquisition step includes at least one of a detection step, for detecting the delay duration, and a delay duration storage step, for storing a pre-specified delay duration, and the acquisition section includes acquiring one of the delay duration detected in the detection step and the delay duration stored in the delay duration storage step.
