Apparatus and method for automatically fetching static picture

[0032] Please also refer to image 3 and Figure 4 This device is a flatbed scanner. In this flatbed scanner, there is a scanning platform 40 for placing static images of scanned documents.

[0033] The device for automatically capturing static images includes a scanning head 20 and a determining device 36.

[0034] Among them, the scanning head 20 is placed directly under the scanning platform 40 as a screen that continuously detects static images. That is to say, the scanning head 20 will be directly driven by the driving component (not shown) after the scanner is activated. The scanning platform 40 is directly below the beginning, so that after we open the upper cover of the scanner, the scanning head 20 can be seen directly above the scanning platform 40.

[0035] The judging device 36 is used to judge the difference between the image information detected by the scan head 20 in the previous period and the image information detected by the scan head 20 in the later period. Because the user may repeatedly correct the fixed-point position of the static image on the scanning platform during the process of placing the static image, the scanning head will detect the fixed-point position of the static image every short fixed clock cycle, so the scanning head 20 Before the end of the scan, it is under the scanning platform, and it is constantly being driven back and forth to continuously detect the new position of the static image.

[0036] In addition, the device for automatically capturing static images further includes: an image capturing device 32 and a buffer 34.

[0037] The image capturing device 32 is coupled to the determining device 36 to capture the image information after the scanning head 20 detects the static image. The image capture device 32 is divided into two types: Charge Couple Device (CCD) and Contact Image Sensor (CIS). However, if a new image capture device is developed in the future, Take the device, it also belongs to the equivalent technology.

[0038] Then, the buffer 34 is connected to the image capturing device 32 and the determining device 36, and serves as a temporary storage for the image information captured by the image capturing device 32 in the previous period.

[0039] Please also refer to Figure 5 and Figure 6 , Which is a method for automatically capturing static images according to another preferred embodiment of the present invention.

[0040] The invention is suitable for a method for automatically capturing static images in a flatbed scanner, in which a scanning platform is provided in the flatbed scanner.

[0041] The present invention aims to simplify the user’s operation flow and the scanner’s processing flow, so the user only needs to Figure 5 In step S500, the power of the scanner is activated, and then, in step S502, the static image is placed on the scanning platform of the scanner, and the scanner can perform pre-scanning or scanning in step S504.

[0042] After the user places the static image in the scanner in step S502, the method of automatically capturing the static image in this embodiment includes: step S600, first detecting whether the static image on the scanning platform has changed, that is Refers to whether the user has corrected the fixed point position of the static image after placing the static image.

[0043] If so, in step S602, it is determined whether the change that has occurred can be maintained for a stable period of time without continuing to change. If the user does not continue to change the fixed point position of the static image for a period of time, the execution can continue in step S606 Setting action, the so-called setting action refers to the pre-scan or scanning action of the scanner. However, if the static image does not remain stable for a certain period of time after the change occurs, but does not continue to change, but keeps changing the position of the static image, you must wait until the new change remains stable for a period of time before performing the setting action.

[0044] Wherein, if there is no change in the static image on the scanning platform in step S604, then in step S604, it is detected whether there is a static image on the scanning platform. If not, the scanner setting action is ended, but If there is a static image on the scanning platform, it means that the user has placed the static image properly at the beginning, and there is no need to calibrate the position of the static image again, so the setting action of step S606 is directly performed.

[0045]If the setting action of this static image has been completed in step S606, it is determined in step S608 whether there is still another still image to be set to perform the setting action, if so, return to step S600 to continue detecting Whether the static image on the scanning platform has changed, until there is no static image to perform the set action, that is, the step of automatically detecting the static image is ended.

[0046] Please refer to Figure 7 , Which is a method for automatically capturing static images according to another preferred embodiment of the present invention. This method is suitable for static image capturing devices that capture static images, such as image capturing devices similar to digital cameras or platform type Scanner etc.

[0047] The steps of the method for automatically capturing static images include: the static image capturing device continuously detects whether the static image has changed (step S700), and if the detection knows that the detected static image has changed, then in step S702, it is determined Whether the changes that have occurred have remained stable for a period of time without continuing to change. If it remains stable for a period of time and does not continue to change, then in step S704, perform an image capturing action on the static image.

[0048] If it is known that there is no change in the static image through continuous detection in step S700, the image capturing action of step S704 cannot be performed on the static image.
