MEDICAL IMAGE RECORDING DEVICE
First Claim
1. A medical image recording device that shoots by putting, on a body of an operator conducting medical treatment, an image pickup device that includes at least an optical lens and an image pickup element which generates an image pickup signal by photoelectrically converting light introduced from a subject via the optical lens during shooting, the medical image recording device comprising:
- an image pickup control unit that controls in such a way as to display, on a display unit, a video from image data that is generated for each of frames that constitute the video based on the image pickup signal;
an information recording unit that sequentially records the image data;
a movement detection unit that sequentially compares the image data between consecutive or adjacent frames, and calculates an amount of movement of the image pickup device based on a positional shift of a main subject between the frames;
a camera shake correction unit that corrects, when the amount of movement is within a preset range, a positional shift of the video caused by the movement corresponding to the amount of movement; and
a recording control unit that controls stopping of the recording of the image data on the information recording unit when the amount of movement is greater than an upper limit of the range.

Abstract
A medical image recording device includes an image pickup device generating an image pickup signal by photoelectric ally converting light reflected from a subject with use of an image pickup element, wherein an image pickup control unit displays, on a display unit, image data generated for each of frames constituting a video by processing the image pickup signal. A recording control unit records the image data on a memory card. A movement detection unit sequentially compares the image data between the adjacent frames, and calculates an amount of movement of the image pickup device from a positional shift of a main subject between the adjacent frames. If the amount of movement is within a preset range, a camera shake correction unit corrects a blur. If the amount of movement is greater than an upper limit of the range, the recording control unit stops recording of image data on the memory card.

11. A medical image recording device that shoots by putting, on a body of an operator conducting medical treatment, an image pickup device that includes at least an optical lens and an image pickup element which generates an image pickup signal by photoelectrically converting light introduced from a subject via the optical lens during shooting, the medical image recording device comprising:
-
an image pickup control unit that controls in such a way as to display, on a display unit, a video from image data that is generated for each of frames that constitute the video based on the image pickup signal; an information recording unit that sequentially records the image data; an acceleration sensor that detects movement of the image pickup device; a first movement detection unit that calculates an amount of movement of the image pickup device based a detection signal of the acceleration sensor; a camera shake correction unit that controls in such a way as to cancel a blur in the video caused by the movement corresponding to the amount of movement calculated by the first movement detection unit; a second movement detection unit that sequentially compares the image data between consecutive or adjacent frames, and calculates an amount of movement of the image pickup device from a positional shift of a main subject between the frames; and a recording control unit that controls stopping of the recording of the image data when the amount of movement calculated by the second movement detection unit is greater than or equal to a preset threshold value. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
