摘要： The image data forming apparatus and an image data processing method for recording image data on an image data recording medium in a wide dynamic range and reproducing a finished image from the image data. The apparatus separates a wide dynamic range image signal of an image, generated from a solid-state imaging device, into main data M suitable for forming the finished image and highlight data H having a higher range with the use of a range separator, associates the main data M with the highlight data H, and records them in an image recording memory. At this time, a main data processor performs gradation control and compression on the main data M. A highlight data processor performs gradation control and compression on the highlight data H as necessary. An image reproducer reads out the main data M and the highlight data H, associated with each other as one image, from the image recording memory and develops them on a common axis Q for composition. This restores the original dynamic range image signal and allows the image to be reproduced on a printer. From the main data M, the image is displayed on a video monitor as the finished image.

摘要： An optical low-pass filter for a solid-state image sensor of an offset sampling structure is constituted of first and second optical members. The first optical member splits an incident light ray into a rectilinear ray and a refracted ray whose propagation direction is about 45° to a horizontal direction of the solid-state image sensor. The second optical member splits an incident ray into a rectilinear ray and a refracted ray whose propagation direction is about 90° to the horizontal direction. The optical low-pass filter having this configuration splits the incident light ray into four rays whose split points are at respective corners of a parallelogram. Assuming that Px represents a sampling interval in the horizontal direction, Py represents a sampling interval in the vertical direction, and D1 and D2 represent respective split widths of the incident light rays through the first and second optical members, the split widths D1 and D2 satisfy the following conditions: D1≈Px/{square root over (2)} and Py≦D2≦2·Py.
