Problems solved by technology

However, the user may capture an image of a subject in backlight or in excessive exposure on purpose.
However, in the printing vending machines in the related art, since captured images are displayed as a list of small thumbnail images, it is difficult to find abnormalities of images which should be corrected.
In the printing vending machines in the related art, even when an abnormality is not found in the displayed list of thumbnail images, an abnormality such as a red-eye portion, low brightness, or low saturation may be found after printing.
Here, there arises a problem that the printing vending machines in the related art do not appropriately correct abnormalities of images.

first embodiment

(2) Operation of First Embodiment

[0041]With the configuration described above, in the printer 1, when a user inserts a memory card in the insertion slot 4 (refer to FIGS. 1 and 2), the memory card reader 11 and the image reading unit 12 successively acquire images recorded in the memory card and the images are displayed as a list of thumbnail images on the display unit 3. When the user selects images to be printed from the displayed list and pays a charge for printing the images, the images selected by the user are printed by the printing unit 15 and dispensed from the picture dispensing slot 8. Accordingly, users who do not have a computer may use the printer 1 to print images captured by electronic still cameras or cellular phones including cameras.

[0042]In such a series of processes of the printer 1, when the images are read from the memory card, the image processor 14 detects abnormalities such as a red-eye portion and a backlight image, and the abnormalities of the images are d...

second embodiment

(4) Second Embodiment

[0048]The configuration of the first embodiment has the following drawback. All images input from the memory card are successively subjected to detection of an abnormality, resulting in an excessively high processing load. Accordingly, in this embodiment, only abnormalities of images which are instructed to be corrected by the user are displayed and are corrected in response to the user's instruction. Note that the printer of this embodiment has the same configuration as the printer 1 shown in FIG. 1 except for processing of abnormalities of images controlled by the controller 13. Accordingly, FIG. 1 is used for explanation of a configuration of the controller 13 in this embodiment hereinafter.

[0049]FIG. 6 is a flowchart illustrating a processing procedure of the controller 13. The controller 13 controls the display unit 3 to display operation guides. When a memory card inserted in the insertion slot 4 by a user is detected, the controller 13 starts performing t...

Abstract

The present invention is employed for self-service printing vending machines installed in various stores, for example. The present invention is provided for detecting an abnormality of an image and for displaying the abnormality with the corresponding image to be printed. The abnormality is corrected in accordance with an instruction by a user.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates to printers and methods for controlling the printers and may be employed in self-service printing vending machines installed in various stores, for example. The present invention is used for detecting an abnormality of an image and informing a user of the abnormality to thereby appropriately correct the abnormality of the image.[0003]2. Background Art[0004]In general, various stores such as convenience stores provide self-service printing vending machines. Even users who do not have computers may use the printing vending machines to print images captured using electronic still cameras or cellular phones including cameras, for example.[0005]Such a self-service printing vending machine is a printer used for printing image data recorded in a memory card as a recording medium. When a memory card used with an electronic still camera or a cellular phone including a camera is loaded in the self-service p...
