摘要: An image sensor includes, inter alia, a pixel array, read-out circuit blocks, and switching units. The pixel array includes unit pixels arranged in rows and columns. Two or more read-out circuit blocks sample, amplify, and perform analog-to-digital conversion on unit pixel data to read image data of the pixel array. The switching units establish connection between column lines of the pixel array and the read-out circuit blocks. The switching units establish connection between the column lines of the pixel array and the read-out circuit blocks such that data of all of the sampled pixels in a sub-sampling mode is processed by less than all of the read-out circuit blocks.
