摘要： A color image signal processing method for a color image input/output system reads an original by an image input section and corrects the color and gradation of the thus obtained image signals and feeds output density signals for each color to an image output device. The processing method includes the steps of calculating differences between desired finished densities and the output density signals at specified points on the original which are obtained by converting input density signals on the specified points based upon reference gradation conversion curves and then prepares characteristic curves of the differences with respect to the output density signals using the same functions for the respective colors and then prepares corrected gradation conversion curves by adding the reference gradation conversion curves to the functions. The functions are then determined so that the corrected gradation conversion curves are within a specified inclination range so as to thereby correct a gradation conversion table as well as correcting a color correction table by limiting the values of color correction coefficients so as to remove color distortion of output images.

摘要： An image processing apparatus comprising positive and negative original input signal processing sections respectively converting positive and negative signals obtained by photoelectric scanning of positive and negative originals into positive density signals, and a color processing section for color-processing the positive density signals. The circuits used in the positive original input signal processing section are preferably all included as well in the negative original input signal processing section, so that common circuits may be employed for the two processing sections. This is similarly the case with the positive and negative image output sections. The apparatus also has a positive image output section for converting the output signal of the color processing section into a light amount control signal for a light source for reproducing a positive image, and a negative image output section for converting the output signal of the color processing section into a negative density signal and then into a light amount control signal for forming an intermediate negative so that a desired density is obtained on an ultimate printing photosensitive material when the intermediate negative is printed thereon. During processing in the negative original input signal processing section, a negative original density signal is converted into a density signal representing a corresponding positive image such that the weight of ratio of the Y, M and C color signals is always 1:1:1 for a gray original.

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： 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： 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.
