摘要:
A process for development-processing a silver halide photographic light-sensitive material is described, comprising processing with a developing solution containing 0.1 mol/liter or more of sulfite ion and at least one compound represented by formula (I) ##STR1## wherein n represents an integer of from 2 to 6; each of R.sub.1 and R.sub.2 represents hydrogen or an alkyl group having from 1 to 6 carbon atoms; and M represents hydrogen or an alkali metal atom.According to the process, the generation of silver sludge and the formation of fog are prevented when a black-and-white photographic light-sensitive material is processed with a developing solution containing sulfates in a high concentration.

摘要:
A compound-eye imaging device comprises an imaging device body having 9 optical lenses and a solid-state imaging element for imaging unit images formed by the optical lenses. Assuming that the combination of each of the optical lenses with a corresponding divided area of the solid-state imaging element to image each of the corresponding unit images is an imaging unit, thereby forming multiple imaging units, the respective imaging units have randomly different optical imaging conditions. For example, the focal lengths of the 9 optical lenses are set to have random values in which the optical lenses are arranged to have random distances between adjacent ones thereof in a direction parallel to the major surface of the solid-state imaging element. This compound-eye imaging device substantially prevents unit images formed by respective imaging units from being the same, making it possible to easily increase the definition of a reconstructed image.

An imaginary object plane is set in front of an imaging device body (plane setting step). A part of optical conditions of optical lenses are changed as variables, and positions of points (pixel observation points) on the imaginary object plane where lights coming from pixels of a solid-state imaging element and back-projected through the optical lenses are calculated (pixel observation point calculating step). The dispersion in position of the calculated pixel observation points is evaluated (evaluating step). Finally, a set of values of the variables giving maximum evaluated dispersion of the calculated pixel observation points is determined as optimum optical condition of the optical lenses (condition determining step). This reduces the number of pixels which image the same portions of the target object, making it possible to reduce portions of the same image information in multiple unit images, and to stably obtain a reconstructed image having a high definition.

A compound-eye imaging device comprises a flash control means for controlling a flash unit to alternatively emit two kinds of near-infrared lights having different wavelengths while multiple single-eye images are read using a rolling shutter; a single-eye image reading means for reading, from the single-eye images, a single-eye image (hereafter “pre-change single-eye image”) imaged under a first illumination condition before an illumination condition change by the flash control means, and a single-eye image (hereafter “post-change single-eye image”) imaged under a second illumination condition after the illumination condition change; and an eye position detecting means for detecting eye positions in the single-eye images based on a comparison between the read pre-change and post-change single-eye images. This imaging device can further comprise: a face extracting means for extracting a face area based on the detected eye positions; and a personal identification means for performing personal identification based on the extracted face area.

A panoramic imaging device comprises: a photodetector array; a lens array having, on one plane, a center lens for receiving light in a front range of 36° to form a central unit image on the photodetector array, and left and right side lenses for receiving lights in left and right ranges each of 72° in capture angle of 180°; and four prisms in two pairs placed facing the side lenses. The two pairs of left and right prisms (more inclined and less inclined pairs) collect lights in divided two pairs of left and right ranges each of 36° in the 72° range (pairs closer to, and farther from, the front range), respectively, to form four side unit images on the photodetector array which are combined with the central unit image to reproduce a panoramic image without using wide-angle lenses or complex image correction process.
摘要:
A center lens for collecting light in a center range and left/right lenses for collecting light in left/right ranges are supported in one plane to form center and left/right unit images. A microprocessor combines the unit images into a wide-angle image. The left/right optical lenses are placed on left-right direction line parallel to the wide-angle direction, while the center lens is placed distant from the left/right lenses above the direction line. Prisms are placed in front of the left/right lenses, and a toroidal lens to vertically modify the light path for light convergence onto each lens is placed in front of the prisms. The toroidal lens has a vertically curved surface having an axis coinciding with the direction line, and a horizontally cured surface having an axis coinciding with a vertical line passing through the center lens. This device can obtain a wide-angle image with a vertically large picture angle.

The light reception element is disposed so as to face the lens attached to the fitting member, and an image of a photographic subject is projected upon this light reception element by the lens. An image output unit is also provided which outputs this image of the photographic subject projected upon the light reception element by the lens. And an application aperture for adhesive is provided in the fitting member at a position facing a region of the lens which does not contribute to the image of the photographic subject outputted by the image output unit. Desirably, a plurality of such admission apertures are provided.

A photographic device includes an image sensor in which a plurality of pixels are arrayed. A vertical scan circuit selects horizontal drive lines of the image sensor in order. And a horizontal scan circuit reads out in order voltages due to electric charges from the pixels in the horizontal row which is selected by the vertical scan circuit. A plurality of optical lenses are arranged in a direction parallel to the vertical drive lines, and these optical lenses form images of the same photographic regions upon respective pixel regions which face them. The voltages due to electric charges are read out in order from the pixels, and a plurality of images are acquired with some time difference between them. The emission of light by a light source is controlled, so that photography in each of the pixel regions is performed in different photographic conditions.
摘要:
There is provided an information processing apparatus in which a CPU and an audio processing unit are coupled by a bus. The audio processing unit includes a ring buffer that temporarily retains audio data, and performs an input/output process of the audio data. An interrupt signal generator generates a buffer empty signal, when the audio data is output from a buffer in the ring buffer and the buffer is empty, decimates the buffer empty signal in accordance with a sampling frequency of audio, and then feeds the interrupt signal that survives the decimation to the CPU. The CPU, upon receiving the buffer empty signal, issues a DMA transfer instruction for writing the audio data into the empty buffer in the ring buffer.
