The invention provides a scanning module, a scanning method, an electronic shutter and a camera device. The scanning module comprises a first scanning circuit and a second scanning circuit; during scanning time period, the first scanning circuit provides a first scanning signal for the odd-numbered rows of photosensitive units in the odd-numbered columns in sequence from left to right; wherein thefirst scanning circuit provides a first scanning signal to the even-number-column even-number-row photosensitive units from left to right, the second scanning circuit provides a second scanning signal to the even-number-column odd-number-row photosensitive units from right to left, and the second scanning circuit provides a second scanning signal to the odd-number-column even-number-row photosensitive units from right to left; alternatively, the first scanning circuit provides a first scanning signal to the odd-number-column even-number-row photosensitive units from left to right. wherein thefirst scanning circuit provides a first scanning signal for the even-number-column odd-number-row photosensitive units in sequence from left to right, the second scanning circuit provides a second scanning signal for the even-number-column even-number-row photosensitive units in sequence from right to left, and the second scanning circuit provides a second scanning signal for the odd-number-column odd-number-row photosensitive units in sequence from right to left. The present invention reduces bright and dark fringes occurring during image pickup.
