111results about How to "Improve screening rate" patented technology

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.
