A calibration method includes acquiring a captured image of a lattice fringe by providing a reference gauge having a reference surface whose height from a reference plane changes in a first direction, projecting a fringe pattern having the same phase along the first direction with respect to the reference surface and having a phase changing in a second direction crossing the first direction, and imaging the fringe pattern; calculating a phase of each pixel along the first direction in the captured image of the fringe pattern; and generating relational data in which the height of the reference surface corresponding to the pixel, the phase calculated with respect to the pixel, and a period of the fringe pattern at the time of calculating the phase are associated with each other.

A picture transmission/reception system includes: an information supply apparatus that supplies, sequentially in time, combined information including picture information and counterpart-picture location information representative of a location of counterpart-picture information that is information about a picture related to the same subject-of-display but different in processability attribute from the picture information; and a picture receiver apparatus that has a receiving part that receives the combined information supplied by the information supply apparatus, a picture-display processor that displays, sequentially in time, picture information included in the combined information received at the receiving part, and a counterpart-picture-data acquirer that analyzes counterpart-picture location information corresponding to a picture selected by a user out of pictures displayed by the picture-display processor and accesses a location of the counterpart-picture in a data storage apparatus that stores the counterpart-picture represented by the counterpart-picture location information, to thereby acquire one of counterpart-picture data related to the one piece of picture information. The counterpart-picture-data acquirer of the picture receiver apparatus is configured to detect a processability attribute as to the acquired one of counterpart-picture data, and evaluate whether or not the detected processability attribute is suited for a predetermined use by the user and related to a highest or comparatively higher quality acquirable. When a result of evaluation is negative, a retrieval processing is made to retrieve for another one of counterpart-picture data having a processability attribute for a comparatively higher quality while, when the result of evaluation is affirmative, the picture data evaluated is outputted.

An image retrieving device for classifying and retrieving an image by detecting an object in the image and adding a keyword comprises an image storing section for storing the image which is supposed to be classified and retrieved together with the keyword in a database, an object acknowledging section for acknowledging a predetermined object in the image which is inputted, a keyword proposing section for proposing the keyword which relates to the object which is acknowledged by the object acknowledging section, and an object information inputting section for confirming, adding, and correcting the keyword which is proposed by the keyword proposing section. By doing this, the object in the image is detected for classifying the image; thus, it is possible to provide an image retrieving device in which the keywords are added to the image efficiently.

A head-top detecting method is provided for detecting a head-top of a human face from an image with the human face included therein. After detecting a human face and setting a head-top detecting window at an upper part of the image, an image feature quantity within the head-top detecting window is calculated in a vertical direction and a location in which the image feature quantity changes with a threshold value or more is identified as the head-top of the human face. Thereby the head-top of a human face can be detected accurately and quickly.

An image retrieving system is provided which is suitable for acquiring a retrieving result or a classifying result according to the desire of a user. The system extracts a noticing area from a retrieving key image and each retrieving object image, and a characteristic vector V of these images is generated on the basis of the extracted noticing area. An image similar to the retrieving key image is retrieved from a retrieving object image registration database on the basis of the generated characteristic vector V.

A method of correcting the deviation of a position at which a human face is detected using a face detection frame F. An image G within the detection frame F is divided left and right along the portion of the center axis C. The degree of similarity of mirror-symmetrical relationship between the image portions G-and G-obtained by the division is calculated. An amount of positional deviation d that maximizes the degree of similarity and its direction are found. The frame F is moved a distance corresponding to the amount of positional deviation d in the direction. Thus, the deviation of the detection position due to the detection frame F can be corrected by a quick and simple method.

An error when adjacent pixels are converted into binary values while a subject pixel within a color image is scanned is added to the value of the subject pixel at a predetermined ratio, and a value corresponding to the total number of pixels which take the value of '1' among those pixels which are adjacent pixels and which have been subjected to binarization conversion is added to a binarization threshold value Th. Then, when the value of the subject pixel exceeds the binarization threshold value Th, the value of the subject pixel is converted into '1'. In contrast, when the value of the subject pixel is equal to or less than the binarization threshold value Th, the value of the subject pixel is converted into &#x201c;0&#x201d;.

The invention provides high-speed and high-quality printing when the vertical and horizontal resolutions of print data to be printed differ from the vertical and horizontal resolutions which a printer can process. A table is provided, in which the relationship of position in each printing pass of each of a plurality of pins aligned in the vertical direction of a printing head to a plurality of raster lines in a predetermined range to be printed is examined, whereby the pins aligned in the vertical line to be actuated in each printing pass are determined based on the relationship of a position between each of the pins and each of the raster lines. The table serves as a raster-line/pin-relationship table. A printer driver receives print data from a print-data forming unit, consults the raster-line/pin-relationship table, and actuates the pins for each printing pass according to the raster-line/pin-relationship table.
