Image input apparatus

An image input apparatus comprising:

• an image input unit adapted to input a plurality of images from an object;
• a synthesizing unit adapted to synthesize said plurality of images inputted into said image input unit, to form a synthesized image;
• a detecting unit adapted to detect at least one of a movement of the object, vibration in an original mount or a main body of the apparatus, an interposition of a view blocking obstacle, and a temporal change in luminance of the same portion in the object, and determine a validity or invalidity of said plurality of images for synthesis into a synthesized image, in accordance with a detection result;
• and
• a control unit adapted to control said plurality of images not to be synthesized, when determined to be invalid, and to control said plurality of images to be synthesized, when determined to be valid,
• wherein said detecting unit determines invalidity when the change is larger than a predetermined value, and
• wherein said control unit causes the plurality of images to be re-input from said input unit and stored in a storage unit when said detecting unit determines invalidity.

An image input apparatus comprising:

• an image input unit adapted to input a plurality of images from an object;
• a synthesizing unit adapted to synthesize said plurality of images inputted into said image input unit, to form a synthesized image;
• a detecting unit adapted to detect at least one of a movement of the object and a temporal change in luminance of a portion of the object, and to determine a validity or invalidity of said plurality of images for synthesis into a synthesized image based on the detected movement of the object and/or the detected temporal change in luminance of a portion of the object;
• and
• a control unit adapted to control said plurality of images not to be synthesized, when determined to be invalid, and to control said plurality of images to be synthesized, when determined to be valid.

A method of processing signals comprising the steps of:

• inputting a plurality of images from an object;
• synthesizing said plurality of images inputted in said input step into a synthesized image;
• detecting at least one of a movement of the object and a temporal change in the luminance of a portion of the object, and determining validity or invalidity of said plurality of images for synthesis into a synthesized image based on the detected movement of the object and/or the detected temporal change in luminance of a portion of the object;
• and
• controlling said plurality of images not to be synthesized, when determined to be invalid, and controlling said plurality of images to be synthesized, when determined to be valid.

A computer-readable medium for storing a program to process signals, the program being executable by a processor controlled image processing apparatus to perform a method comprising the steps of:

• inputting a plurality of images from an object;
• synthesizing said plurality of images inputted in said inputting step to form a synthesized image;
• detecting at least one of a movement of the object and a temporal change in luminance of a portion of the object, and determining validity or invalidity of said plurality of images for synthesis into a synthesized image based on the detected movement of the object and/or the detected temporal change in luminance of a portion of the object;
• and
• controlling said plurality of images not to be synthesized, when determined to be invalid, and controlling said plurality of images to be synthesized, when determined to be valid.
