An image capturing method includes steps of providing an image capturing device, obtaining a captured image, a first displacement data and a second displacement data, calculating to obtain an angle deflection data according to the first displacement data and the second displacement data, calculating to obtain a central point real coordinate corresponding to a central point of the image capturing device, calculating to obtain an initial point real coordinate corresponding to an initial point of the captured image and a finish point real coordinate corresponding to a finish point of the captured image, and determining a real coordinate system according to the central point real coordinate, the initial point real coordinate and the finish point real coordinate and correspondingly outputting the captured image with the real coordinate system so as to obtain a corrected terminal image. As a result, the terminal image is similar to the original image.

An array of pixels of a solid-state imaging sensor having a rolling shutter is sequentially exposed to capture images from an illuminated target over successive frames for image capture by an imaging reader. The target is illuminated at a peak output power level for a fractional time period of a frame, and is not illuminated for at least a portion of a remaining time period of the frame for increased energy efficiency. Only a sub-array of the pixels is exposed during the fractional time period in which the target is being illuminated at the first output power level.

An image reading apparatus (6) includes a document placing table (6a) to an upper surface of which a contact glass (25) is fixed, and a document pressing device (24) supported at an end of the document placing table (6a) to be openable/closable via a hinge portion, and having, on its back surface side, a document presser (30) that presses a document placed on the contact glass (25). The document pressing device (24) includes a light transmission window (31) transmitting light in a front-surface-to-back-surface direction of the document pressing device (24). The light transmission window (31) is disposed at a position not overlapping with the contact glass (25) when the document pressing device (24) is at the closure position, and when the document pressing device (24) has moved in an opening direction from the closure position, light that has passed through the light transmission window (31) reaches the contact glass (25).
