摘要:
When image data are input from a memory card or the like, a printing apparatus detects face region captured in these image data. Where the size and position of a face region fall within permitted ranges therefor set in advance in a permitted range table derived via sense evaluation testing, the input image data is selected as a printing target candidate. If the face region size and position do not each fall within their permitted range, however, the image data is not selected as a printing target. As a result, image data suitable for printing can be efficiently selected as printing targets from image data that contain human faces.

Image processing apparatus and methods are provided for detecting coordinate positions of characteristic portions of a face image. A method includes identifying a face area of the target image, determining initial coordinate positions for characteristic portions, selecting at least one characteristic amount used for correcting the initial coordinate positions or previously generated corrected coordinate positions, determining corrected coordinate positions by using the selected at least one characteristic amount, and detecting the corrected coordinate positions as the coordinate positions.

Image processing apparatus and methods are provided for specifying the positions of predetermined characteristic portions of a face image. A method includes determining an initial disposition of characteristic points in a target face image, applying a transformation to at least one of the target face image or the reference face image, and updating the disposition of the characteristic points in response to a comparison between at least one of the transformed target face image and the reference face image or the target face image and the transformed reference face image.

In order to detect an orientation of a human face included in an image consisted of a plurality of pixels, a face region is determined within the image so as to include the human face. A plurality of detecting regions are set so as to be adjacent to the face region. A plurality of first amounts are acquired. Each of the first amount is characteristic to one of the detecting regions. The first amounts are compared to each other to judge the orientation.

An image processing apparatus includes: a face area detecting unit detects a face area corresponding to a face image in a target image; an image generating unit that generates an organ detecting image including the face image which is inclined in a predetermined angular range in an image plane on the basis of the detection result of the face area; and an organ area detecting unit that detects an organ area corresponding to a facial organ image in the face area on the basis of image data indicating the organ detecting image.

The focusing information visualization system of the invention extracts an edge having an edge intensity of not less than a first reference value Th1 and an edge width of not greater than a second reference value Th2 in a photographic image and displays the extracted edge in a preset color at a position of the edge extraction to be overlapped with the original photographic image on a screen. A focused area defined by the extracted edge is displayed as N divisional areas. In response to a user's operational specification of one divisional area among the N divisional areas, an enlarged photographic image corresponding to the specified divisional area at a desired magnification ratio is displayed on the screen. This arrangement adopts the automatic rough judgment and the user's final visual check to accurately recognize the focusing status of the photographic image.

There is provided an exposure determining device that determines whether exposure of an image represented by image data is appropriate. The exposure determining device includes a first evaluation value deriving unit that derives a maximum luminance reference value for each of blocks obtained by dividing the image into a plurality of blocks of the image data on the basis of luminance values of pixels constituting each block, and derives a first evaluation value for the image on the basis of the derived maximum luminance reference values for the blocks, and an exposure determining unit that determines whether exposure of the image is appropriate, on the basis of the derived first evaluation value.

A reversely-rotatable roller conveys a sheet having an image formed on its one side at a sheet conveying velocity faster than that of a conveying roller by normal rotation and then, the reversely-rotatable roller conveys the sheet to a re-conveying path by reverse rotation. The sheet conveying velocity of the reversely-rotatable roller when the reversely-rotatable roller reversely rotates is made slower than the sheet conveying velocity when the reversely-rotatable roller normally rotates so that the sheet conveying velocity of the re-conveying roller is substantially equal to or slower than the sheet conveying velocity of the conveying roller.
