- the monochrome original image input means for inputting the monochrome original image from the outside, the input An image conversion means that degenerates the original monochrome image and converts it into a display image with a pixel power of q rows (3 * n * q / m), and the monochrome LCD sub-pixels are driven independently to display the display image.
- an image display program for causing a display image output means for outputting the display image to the monochrome liquid crystal display device for display.
- a monochrome original image having pixel power of m rows and n columns is degenerated and converted to a display image composed of pixels of q rows (3 * n * q / m). Since the number of pixels corresponding to the aspect ratio (nZm) of the original monochrome image is (n * qZm), the number of pixels in the row direction of the display image is three times the number of pixels corresponding to the aspect ratio (nZm) of the original monochrome image. It has become. However, in each pixel of a monochrome LCD, three subpixels are arranged in the row direction, and these subpixels are driven independently to display a display image.
- the image display device and the image display program of the present invention it is possible to improve the resolution in the major axis direction of the LCD and to display a degenerated image by storing the aspect ratio of the original image. .
- FIG. 1 is a configuration diagram illustrating a medical image display apparatus 1 according to the first embodiment.
- m, n, q, P are natural numbers, and m ⁇ n, q ⁇ P, n / m ⁇ P / q, m> q Medical image data A (i, j) is input and is degenerated and converted into display image data M (k, L) with pixel power of q rows (3 * n * q / m) and output Display image data M (k, L) by independently driving the sub-pixels arranged in the row direction of the monochrome LCD with a personal computer 3 that executes the viewer program 31 and a monochrome LCD with pixel power of q rows and P columns
- the monochrome medical image data A (i, j) comprising the monochrome liquid crystal display device 4 is the m-row n-column pixel array of the medical image photographing device F.
- the image was taken with a PD and stored in the medical image data server D.
- the major axis direction of the medical image data A (i, j) is often the vertical direction of the subject, so the major axis direction of the LCD is often the vertical direction.
- the medical image data A (i, j) and the LCD are horizontally long.
- FIG. 3 is an explanatory diagram showing the relationship between the LCD and the display image data M (k, L).
- the monochrome medical image data AG, j) is degenerated so that the short axis direction of the display image data M (k, L) matches the short axis direction of the LCD. If the aspect ratio nZm of monochrome medical image data A (i, j) is maintained, the number of pixels p in the major axis direction of the display image data M (k, L) becomes shorter than the number of pixels P in the major axis direction of the LCD.
- one pixel U of the LCD is composed of three sub-pixels ul, u2, and u3 forces arranged in the major axis direction of the LCD. Since the pixel U is a square, the subpixels ul, u2, and u3 have a rectangular shape.
- FIGS. 5 and 6 are flowcharts showing the procedure of the medical image viewer process by the medical image viewer program 31 of the personal computer 3.
- step SO monochrome medical image data A (i, j) consisting of pixels of m rows and n columns is read from the medical image data server 2.
- the adjustment value B the operator can adjust the appearance of the displayed image (image noise, etc.).
