Abstract

An imaging apparatus which images pictures using a solid-state imaging device includes a picture conversion unit converting pictures imaged at a high-speed screen rate by the solid-state imaging device into a picture in which n-pieces (''n'' is an integer of 2 or more) of continuous imaged pictures are arranged in one screen and outputting the converted picture at a low-speed screen rate which is 1 / n of the high-speed screen rate, a signal processing unit performing predetermined picture-quality compensation processing to the picture from the picture conversion unit, a display picture cutting unit cutting one of n-pieces of imaged pictures from pictures processed by the signal processing unit and outputting the picture at the low-speed screen rate, and a display processing unit generating picture signals for displaying the picture outputted from the display picture cutting unit at a display device.

[0088] In the first embodiment described above, the playback compatibility of the recorded image data is ensured by recording the image data as HD images at 30 fps in the high-speed imaging mode. However, in the second embodiment, image data recorded in the high-speed imaging mode is recorded as an image at 120 fps at the same refresh rate as that at the time of imaging.

[0089] FIG. 7 is an explanatory diagram of a signal flow at the time of recording an image in the second embodiment.

[0090] In FIG. 7, images are imaged at 120 fps from the imaging device 12, these images are converted into SD images, and 4 SD images are merged into one HD image until the image quality correction (step Steps S31 to S34) are the same as the first embodiment in FIG. 3 (steps S1-S4).

[0091] Next, the image cutting unit 14a reads out the HD image in which four SD images are combined from the storage area 33b, and then cuts out each area of ​​the SD image from the HD image. After that, one ...
