Abstract
A CPU provided in an image display device of an image exposure device causes a display unit of the image display device to display a display image for divided exposure, which has a divided gradation value obtained by dividing a gradation value of a recorded image, and sequentially performs a plurality of exposures of the photosensitive recording medium by the display image for divided exposure to perform a divided exposure for recording the recorded image on the photosensitive recording medium.
Claims14
An image exposure device comprising:
- an image display device having a plurality of pixels;
- a support portion that supports a photosensitive recording medium for recording a display image displayed on the image display device in a state in which an exposure surface of the photosensitive recording medium faces the image display device;
- a limiting member that is provided between the image display device and the support portion and limits an angle of light emitted from the image display device to the photosensitive recording medium;
- at least one processor;
- and
- a memory that stores instructions that are able to be executed by the processor,
- wherein the processor is configured to
- cause the image display device to display a display image for divided exposure, which has a divided gradation value obtained by dividing a gradation value of a recorded image, and
- sequentially perform a plurality of exposures of the photosensitive recording medium by the display image for divided exposure to perform a divided exposure for recording the recorded image on the photosensitive recording medium,
- wherein a sum of the divided gradation values of the display image for divided exposure used for each exposure in the divided exposure exceeds a maximum gradation number, which is a maximum value of gradations that are able to be displayed on the image display device.
An image exposure method in an image exposure device including an image display device having a plurality of pixels, a support portion that supports a photosensitive recording medium for recording a display image displayed on the image display device in a state in which an exposure surface of the photosensitive recording medium faces the image display device, and a limiting member that is provided between the image display device and the support portion and limits an angle of light emitted from the image display device to the photosensitive recording medium, the method causing a computer to execute a process comprising:
- causing the image display device to display a display image for divided exposure, which has a divided gradation value obtained by dividing a gradation value of a recorded image;
- and
- sequentially performing a plurality of exposures of the photosensitive recording medium by the display image for divided exposure to perform a divided exposure for recording the recorded image on the photosensitive recording medium,
- wherein a sum of the divided gradation values of the display image for divided exposure used for each exposure in the divided exposure exceeds a maximum gradation number, which is a maximum value of gradations that are able to be displayed on the image display device.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a process on an image exposure device including an image display device having a plurality of pixels, a support portion that supports a photosensitive recording medium for recording a display image displayed on the image display device in a state in which an exposure surface of the photosensitive recording medium faces the image display device, and a limiting member that is provided between the image display device and the support portion and limits an angle of light emitted from the image display device to the photosensitive recording medium, the process comprising:
- causing the image display device to display a display image for divided exposure, which has a divided gradation value obtained by dividing a gradation value of a recorded image;
- and
- sequentially performing a plurality of exposures of the photosensitive recording medium by the display image for divided exposure to perform a divided exposure for recording the recorded image on the photosensitive recording medium,
- wherein a sum of the divided gradation values of the display image for divided exposure used for each exposure in the divided exposure exceeds a maximum gradation number, which is a maximum value of gradations that are able to be displayed on the image display device.
