Image capturing apparatus and image capturing method
First Claim
1. An imaging apparatus, comprising:
- an image sensor that includes a color filter array and is configured to output at a first frame rate a first number of first frames of image data that have not yet been subjected to white balance processing; and
circuitry configured to;
(a) in a recording process,compress the first frames of image data, without previously performing white balance processing thereon, to generate compressed image data;
store the compressed image data on a storage medium; and
generate a first signal representing a first white-balanced image sequence that is to be displayed on a display as a camera-through image by processing the first frames of image data to generate a second number of white-balanced second frames of image data that is lower than the first number of first frames of image data, and by processing the white-balanced second frames of image data at a second frame rate which is lower than the first frame rate; and
(b) in a reproduction process,read the compressed image data from the storage medium;
decompress the compressed image data to produce decompressed frames of image data; and
generate a second signal representing a second white-balanced image sequence to be displayed on the display as a slow motion reproduced image by processing the decompressed frames of image data.

Abstract
In a high speed image capturing state, a camera signal processing circuit is not needed to perform a signal process at a high screen rate, but at a regular screen rate. In the high speed image capturing mode, raw data of 240 fps received from an image sensor 101 are recorded on a recording device 111 through a conversion processing section 201 and a recording device controlling circuit 210. Raw data that have been decimated and size-converted are supplied to a camera signal processing circuit 203 through a pre-processing circuit 202 and an image being captured is displayed on a display section 112 with a signal for which a camera process has been performed. In a reproducing state, raw data are read from the recording device 111 at a low screen rate according to a display performance of the display section 112 and the raw data that have been read are processed are processed by the pre-processing circuit 202 and the camera signal processing circuit 203 and a reproduced image is displayed by the display section 112.
