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, gamma correction processing, and YC conversion processing;
at least one processor; and
at least one first storage medium encoded with executable instructions that, when executed by the at least one processor, cause the at least one processor to control circuitry of the apparatus so as to cause the circuitry to;
in a recording process,compress the first frames of image data, without previously performing white balance processing, gamma correction processing, and YC conversion processing thereon, to generate compressed image data;
store the compressed image data, without performing white balance processing, gamma correction processing, and YC conversion processing thereon, on a second storage medium while the second storage medium is attached to the imaging apparatus, the second storage medium being configured to be detachable from the imaging apparatus as to allow the image data to be processed by a device separate from the imaging apparatus when the second storage medium is detached from the imaging apparatus; and
generate a first signal representing a first white-balanced, gamma-corrected, and YC converted 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 second frames of image data that is lower than the first number of first frames of image data, and by performing at least one of white balance processing, gamma correction processing, or YC conversion processing on the second frames of image data at a second frame rate which is lower than the first frame rate.

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.
