Abstract
Abstract In order to accurately perform correction of focal distance and color of film before pre-scanning, the image at the generally center area of the first frame of film is read in a first pre-scan, auto-focusing and judgment between negative/positive is made, exposure parameters are set in a second pre-scanning, and the image is read in main scanning.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
102 words
A control method for a scanner device which has reading means for reading an original image while performing relative scanning of said original image, said control method comprising the following steps: a first scanning step for reading a portion of the original image in order to detect an attribution of said original image; a second scanning step for reading the original image under a condition corresponding to the detected attribution and setting an exposure adjusting condition for reading the original image; and a third scanning step for reading the original image under the exposure adjusting condition set in the second scanning step.
Claim 2
Dependent Claim
102 words
A control method for a scanner device which has reading means for reading an original image while performing relative scanning of said original image, said control method comprising the following steps: a first scanning step for reading a portion of the original image in order to detect an attribution of said original image; a second scanning step for reading the original image under a condition corresponding to the detected attribution and setting an exposure adjusting condition for reading the original image; and a third scanning step for reading the original image under the exposure adjusting condition set in the second scanning step.
Claim 3
Dependent Claim
33 words
A control method for a scanner device according to claim 1 , wherein in said first scanning step, only the generally center portion of the first frame of said original image is read.
Claim 4
Dependent Claim
49 words
A control method for a scanner device according to claim 2 , wherein in said first scanning step, the concentration of the image is detected from the first frame of said original image, thus judging whether or not said original image is a negative film or a positive film.
Claim 5
Dependent Claim
39 words
A control method for a scanner device according to claim 2 , wherein in said first scanning step, the focal distance from the first frame of said original image is set as the condition corresponding to the detected attribution.
Claim 6
Dependent Claim
39 words
A control method for a scanner device according to claim 3 , wherein in said first scanning step, the focal distance from the first frame of said original image is set as the condition corresponding to the detected attribution.
Claim 7
Dependent Claim
33 words
A control method for a scanner device according to claim 1 , wherein in said second scanning step, parameters relating to exposure from said original image are set as the exposure adjusting condition.
Claim 8
Dependent Claim
40 words
A control method for a scanner device according to claim 3 , wherein in the event that said original image is judged to be negative film in said first scanning step, a certain filter is set to perform color correction.
Claim 9
Dependent Claim
21 words
A control method for a scanner device according to claim 1 , wherein said original image is developed 135 mm film.
Claim 10
Dependent Claim
106 words
A scanner device which has reading means for reading an original image while performing relative scanning of said original image, said scanner device comprising: first scanning means for reading a portion of the original image in order to detect an attribution of said original image; second scanning means for reading the original image under a condition corresponding to the detected attribution and setting an exposure adjusting condition for reading the original image; third scanning means for reading the original image under the exposure adjusting condition set by the second scanning means; and control means for controlling said first, second and third feeding means to operate sequentially.
Claim 11
Dependent Claim
106 words
A scanner device which has reading means for reading an original image while performing relative scanning of said original image, said scanner device comprising: first scanning means for reading a portion of the original image in order to detect an attribution of said original image; second scanning means for reading the original image under a condition corresponding to the detected attribution and setting an exposure adjusting condition for reading the original image; third scanning means for reading the original image under the exposure adjusting condition set by the second scanning means; and control means for controlling said first, second and third feeding means to operate sequentially.
Claim 12
Dependent Claim
125 words
Computer-readable memory storing program code for controlling a scanner device which has reading means for reading an original image while performing relative scanning of said original image, said computer-readable memory comprising: code for a first scanning step for reading a portion of the original image in order to detect an attribution of said original image; code for a second scanning step for reading the original image under a condition corresponding to the detected attribution and setting an exposure adjusting condition for reading the original image; code for a third scanning step for reading the original image under the exposure adjusting condition set in the second scanning step; and code for a control step for controlling said first, second and third scanning steps to operate sequentially.
Claim 13
Dependent Claim
125 words
Computer-readable memory storing program code for controlling a scanner device which has reading means for reading an original image while performing relative scanning of said original image, said computer-readable memory comprising: code for a first scanning step for reading a portion of the original image in order to detect an attribution of said original image; code for a second scanning step for reading the original image under a condition corresponding to the detected attribution and setting an exposure adjusting condition for reading the original image; code for a third scanning step for reading the original image under the exposure adjusting condition set in the second scanning step; and code for a control step for controlling said first, second and third scanning steps to operate sequentially.
