For a first region being a portion of a storage section (202), a read-out pulse produced by a progressive scanning shift register (206) is used to perform a progressive read-out operation of reading out signals from all rows of image-storing pixels (221). For a second region including an entire region other than the first region, a read-out pulse produced by a skip scanning shift register (205) is used to perform a skip read-out operation of reading out signals from intermittently-selected rows of image-storing pixels (221). The progressive scanning shift register (206) produces the read-out pulse so that the first region moves every frame and an entire region of the storage section (202) is scanned over a plurality of frames.

A recording process records low-resolution video data while obtaining a high-resolution image in a window region being a portion of an entire image. Then, the process learns, as a resolution conversion rule, a resolution increasing parameter by using the high-resolution image. In a resolution increasing process, the resolution of the recorded low-resolution video data is increased by using the resolution increasing parameter learned in the recording process.

An image display device includes a distance detecting unit for detecting a distance from an outputting signal out of a sensor unit to a viewer, an angle detecting unit for detecting an angle of the outputting signal out of the sensor unit relative to a holding position by a viewer, an approaching state detecting unit for detecting a state how the viewer is approaching the image display device, a display switching controlling unit for displaying an image on an image display unit by obtaining the image based on the detecting result of the approaching state detecting unit, a marker generating unit for generating a marker image to display an approaching position on the image to the viewer, and a sending/receiving unit for sending and receiving necessary image data to and from a magnified image database and a tilt variation close-up image database.

Gray level data of boundary pixels that are adjacent to a block boundary in a photoelectric conversion section is stored. Then, a cumulative histogram regarding the number of pixels for different gray levels is produced based on the stored gray level data separately for each block, and a data table representing the correspondence between each gray level before correction and that after correction for the block to be corrected is produced so as to reduce the difference between the cumulative histograms. The data table is stored in a correction data RAM. By using the data table, the outputs of the block to be corrected are non-linearly corrected for different gray levels.

In this image recording apparatus, imaging sensor obtains two video signals of different signal charge accumulation periods, in a given signal charge accumulation period which is represented by a field or a frame of a video signal, and the two video signals are recorded on a record medium, whereby a video signal of an object having a wide luminance distribution can be recorded, and as for the image reproducing apparatus, a correcting circuit corrects standard-illuminance video information and high-illuminance video information which are reproduced by a reproducing circuit, the user designates an object illuminance range to be output, through an object illuminance range designating circuit, and a level converter converts the luminance into a luminance level which can be output by a display apparatus or a printer, thereby allowing portions which are largely different in object illuminance, to be selectively displayed or output in reproduction.
摘要:
A method and apparatus for driving a solid state image pickup device. The method and apparatus include setting a first signal charging period and a second signal charging period during one frame or field of a video signal for each one of a plurality of unit pixels. The second signal charging period is shorter than the first signal charging period. A first signal charge is produced during the first signal charging period and a second signal charge is produced during the second signal charging period. It is judged whether the first signal charge is saturated or not saturated. Then based on this judgement an input light amount is determined. The input light amount is determined using only the second signal charge when the first signal charge is saturated. The input light amount is determined using only the first signal charge when the first signal charge is not saturated.
