摘要:
A particular color is defined in terms of red, green and blue densities thereof. When the densities fall within a predetermined ellipsoid in a three-dimensional chromaticity coordinate system the axes of which respectively represent the red, green and blue densities, the color is defined to be of the particular color. The ellipsoid is represented by the following formula.dS.sup.2 =C.sub.11 dB.sup.2 +2C.sub.12 dB.multidot.dG+C.sub.22 dG.sup.2 +2C.sub.23 dG.multidot.dR+C.sub.33 dR.sup.2 +2C.sub.31 dR.multidot.dBwhereindB=B-BdG=G-GdR=R-RB: blue density of measured pointG: green density of measured pointR: red density of measured pointB: average blue densityG: average green densityR: average red densityRed, green and blue densities of a number of points on a color negative to be printed are measured by a measuring means. The outputs of the measuring means are normalized by a normalizing circuit so that equal level of density signals can be obtained regardless of the gamma value and the sensitivity of the negatives when the same subject matter is photographed under the same conditions. The normalized densities are put into said formula and dS.sup.2 for each of the measured points is calculated by a computing circuit. The calculated dS.sup.2 is compared with a predetermined constant K by a comparator. When the calculated dS.sup.2 is not larger than the constant K, the measured point is determined to be of the particular color.
摘要:
Red, green and blue densities of a color negative are measured at a plurality of points thereon. The measured densities are normalized by a normalizing circuit so that the same levels of density signals can be obtained regardless of the gamma value and sensitivity of the negatives when the same subject matter is photographed under the same conditions. The normalized density signals are plotted in a chromaticity coordinate system and examined as to whether or not they fall within a given region defining a polygon in the coordinate system. The coordinate system is a two dimensional coordinate system in which the axes thereof represent the combinations of two color densities among red, green and blue densities. When the level of the normalized signals with respect to a given point falls within the given region defined by the polygon, the point is determined to have the particular color.

A hue identifying apparatus for use in color printing, comprising a device for creating high and low order address signals from the difference between a combination of two of the red, green and blue density signals read out at each point on a color photographic film and from that between another combination of two of said signals, and a hue region memory storing at each address the hue information based on a predetermined hue region defined in a two-dimensional coordinate system wherein the axes represent quantized values of the density differences. The address is designated by the high and low order address signals. The apparatus may further have a device for detecting inadequate exposure on the basis of the three-color density signals, and a device for obstructing the transfer of the hue information from the hue region memory or for selecting one of a plurality of hue region memories based on the output of the inadequate exposure detecting means.

Image data sets are filed efficiently in an image storing server. An image generation apparatus reads images from a film, and image data sets representing the images are sent to and registered with the image storing server. The image data sets are stored in a folder generated for each user. The user accesses the image storing server from a communication terminal and carries out filing on the image data sets in the folder, such as sorting according to the date and time of photography. In this manner, the image data sets can be stored in the image storing server in a well-organized manner.

A plurality of picture image data obtained from a film in one film handling operation by a film scanner with the automatic film feeding function are output as prints by a digital printer and also as files in a recording medium by a file outputting device. In the system for providing the above two kinds of output services, the numbers of film scanners, file outputting devices, and digital printers are determined so that the processing performance of each kind of apparatus in a unit time times the number of each kind of apparatus is almost the same, to make each kind of apparatus comprising the system demonstrate its full performance. A medium image obtaining device for obtaining an image file recorded in a medium and a digital camera image obtaining device may further be provided so that the above two outputting services are promptly provided for a picture image such as a processed image recorded in a medium and brought into a service provider by a customer and a picture image recorded by a digital camera, whereby one system can carry out film reading, image obtaining from a medium or a digital camera, picture print generation, and writing a picture image in a recording medium.
摘要:
Pictures recorded by a digital camera can be stored and utilized by a method convenient and appropriate for the situation. The system includes a variety of devices for transferring picture image data recorded by a variety of digital cameras to an image server installed in a DPE or the like. It further includes a variety of accessing devices for enabling the picture image data stored in the image server to be accessed. As such, a user of a digital camera can transfer images, via this system while the user is away from home, thereby enabling continual use of the digital camera.

A user takes in digital image data and photographing information added thereto into a personal computer, and instructs, on a printing instruction screen, a printing format such as whether or not the photographing information should be printed and where the photographing information is to be printed. The content of the instruction is added to the digital image data as printing information and transferred to a printer via a recording medium, for example. The printer prints the photographing information on a picture print based on the printing information when the picture print is generated.

A method and apparatus for maintaining the developing performance of an automatic developing and printing system which develops a photographic film exposed, and automatically makes a print from the developed film by using a photographic paper. A photosensitive material is employed on which the pattern having portions different in the quantity of light has been formed by exposure and by development. This photosensitive material functions in the same way the photographic material having the control strips. Hence, the processing performance of the apparatus can be determined without use of the photographic material having the control strips which is expensive and troublesome to handle.

A photographic printer having a video image printing system for making a print of a video image displayed on a CRT and a photographic image printing system using the CRT as an illumination light source for a film from which a photographic image is printed. A control circuit varies the deflection angle of the CRT yoke to define a narrowed raster area on the CRT screen in accordance with various sizes of films.
摘要:
Tone correction for input video signals is performed on the basis of look-up table data. The state of color tone is decided by using chroma signals each corresponding to one of input video signals, and a luminance signal produced from the input video signals. In response to the particular state decided, signals are produced by applying color correction level adjustment to the input video signals. A highlight point and a shadow point are set up based on one of such adjusted signals so as to produce look-up table data for each of the input video signals. This allows input video data to be subjected to tone correction which corresponds to particular photographing conditions, thereby eliminating overcorrection or undercorrection. Hence, the operator's decision as to the state of color tone is needless so that the ease of operation is promoted.
