  • Patent number: 8644613
    Abstract: 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.

  • Patent number: 8150190
    Abstract: With a minimal process load, to determine level of the image of an image data file, for image data files of a format that saves images in the form of coefficients of discrete frequency components. Image data that includes a plurality of coefficients representing the pattern of change of color of the image are acquired (Step S10). Multiple sets of basic pattern data that respectively include a plurality of basic coefficients representing basic patterns of color change are prepared. Then, based on a comparison of the two, one set of selected basic pattern data is selected from among the multiple sets of basic pattern data (Step S20). Subsequently, the blur level of the image of the image data is calculated, based on the basic blur level associated with the selected basic pattern data (S30-S70).

  • Publication number: 20120059831
    Abstract: In response to a search request, the type of the terminal from which the request originated is determined, and a selection history is weighted and accumulated so that the order of the results of a search carried out according to set search conditions varies depending on the selection history. In the case where the type of the request origin terminal is a terminal type in which the number of search results that can be displayed on a single screen is less than in other terminal types or the movement of the screen is more complicated than in other terminal types and search results have been selected across a plurality of screens, a greater weight is applied to the selection history of the selected search results than for other terminal types.

  • Patent number: 7978247
    Abstract: 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.

  • Patent number: 7920756
    Abstract: A printer fetches a horizontal direction DCT coefficient group and a vertical direction DCT coefficient group for each block from the JPEG data. The printer selects edge patterns similar to the brightness changes expressed by these coefficient groups from a specified table, and records those pattern numbers in a RAM. The printer judges whether or not the brightness changes of the blocks with each other adjacent are continuous based on the pattern number of each block recorded in the RAM. And by connecting the edge patterns when those brightness changes are continuous, the printer accumulates the blur widths that exist extending over the blocks. Then, based on this cumulative value, the printer determines the presence or absence of image blur. It is possible thereby to detect with good precision the blur of images even for high resolution images while reducing the used memory capacity.

  • Patent number: 7712983
    Abstract: When a printing device inputs image data from a memory card, the printing device prints an order sheet whereon are arranged a chart of the image data and setting entry fields for filling in a variety of settings for generating a movie based on these image data. The user uses various marking fields provided on the order sheet to specify the display times for the various image data and the effects to be performed on the various image data. When the printing device uses a scanner to read in the filled-out order sheet, movie data is generated based on the content that is set using this order sheet. The user is able to generate movies easily using this type of printing device.

  • Publication number: 20080137982
    Abstract: The blurring determination device references image data in which are recorded coefficients that are obtained when pixel values forming the image in the spatial domain are converted to the frequency domain, and detects edges oriented in two or more directions, from among the image data, by comparing a series of the coefficients in each of the directions with various types of basic edge patterns whereby typical gradient patterns of the changes in pixel values are represented by values corresponding the coefficients. The representative values of the width of the detected edges is determined in each of the directions, and the image data is determined to not be blurred when the representative values meet the condition of being at or below a certain threshold.
