摘要： An exposure determining device detects densities of a number of picture elements of a color original and displays an image of the color original on a color monitor. A part of a principal subject image of the color original is specified on the color monitor. Based on the measured color density of the specified part, picture elements by which the principal subject image is formed are detected to determine a principal subject image area. By using the detected densities of picture elements included in the prinipal subject image area, at least one image characteristic value is calculated and is used with one of a plurality of previously provided exposure calculating formulas selected according to scenes into which principal subject images are classified, in order to determine the proper exposure for reproducing color images of proper color balance and density.

摘要： Color densities of a color original are measured for a number of picture elements into which the color original is divided. A part of the color original that includes at least one picture element is selected, with whose measured color densities the measured color densities of each picture element are compared to detect picture elements of color densities having a certain relation to the color densities of the selected part of the color original. The picture elements of sufficiently similar color densities can define an extent of image which determines a principal subject image and the remainder of which is background. For the individual image, at least one characteristic value peculiar to the image is then calculated by utilizing the measured color densities of picture elements, and on the basis of the characteristic values the scene of the original is classified to select one of a plurality of previously provided exposure calculating formulas in order to determine the proper exposure for obtaining color prints of proper color balance and density.

摘要： An elongated photographic paper wound in the form of a roll is drawn from the front end portion thereof, an image is exposed an it in a printing portion, and is cut by a cutter. After it has been cut, the front end portion of the photographic paper is returned to the printing portion, and parts of the photographic paper are covered by a pair of mask heads. These mask heads are disposed above the photographic paper when a margin-less image is printed and when image is printed. However, in the case of a margin-less print, a larger area of the image is covered than the area in the case of a margin-provided print.

摘要： A method of focusing a printer in which the focusing of a lens is effected in accordance with an AF curve, printing is effected at an every predetermined pitchs while the lens is being moved by predetermined pitchs each along an optical axis starting from an initial position of the lens and then a lens position is selected at which optimum focus is obtained on the basis of printed images. The printing is repeated while the predetermined pitch is sequentially being made finer, in a case where the predetermined pitch differs from a pitch corresponding to the minimum resolving power of the lens. Thus, the AF curve is compensated for on the basis of the lens position which was selected during the printing at the pitch corresponding to the aforesaid minimum resolving power. Accordingly, it is possible to select an optimum lens position with high accuracy.

摘要： A first film cassette for containing a photographic filmstrip has a first data recording portion formed thereon. Data as to the recording of a plurality of image frames are recorded on the first data recording portion when exposing the filmstrip. The filmstrip is separated from the first film cassette before development. The filmstrip is subjected to a motion-picture-film type developing process constituted by splicing, development and separation of a plurality of filmstrips. The separated filmstrip is wound up in a second film cassette, and thus is preserved in a convenient state. The image recording data stored in the first data recording portion are transferred to a second data recording portion formed on the second film cassette, and are utilized in a printing operation. In a preferred embodiment, the filmstrip has a data recording area formed thereon. The image recording data stored in the data recording area are transferred to a preservative film cassette on a data recording portion. The transferred data are related to information common to all the image frames of the filmstrip.

摘要： An autofocusing apparatus suitable for use in a photographic printer is provided. The printer permits mounting of plural carriers for holding original films of different sizes thereon respectively and is capable of setting a focusing position on the basis of an AF curve determined when a reference carrier out of a plurality of carriers is mounted. The apparatus is also so constructed that the AF curve is compensated based on differences between the position of the original film upon mounting of the reference carrier and that of the original film upon mounting another carrier. Accordingly, an original film can be positioned at its optimal focusing position regardless of which of the plurality of carriers is used.

摘要： In a method of determining printing exposures, an original image to be printed is divided into at least two image extents, namely, a principal subject and a background, from each of which at least one image characteristic value is obtained based on the color densities thereof. On the basis of the obtained image characteristic values the proper exposure is determined for obtaining prints of proper densities. The proper exposure is performed by basic exposure control in which the basic exposure is obtained from the image characteristic value, or its artificially weighted value, of the principal subject image extent, and by color correction whose amount is determined either from the characteristic value of the background image extent or from the characteristic values of the both image extents.
