    Abstract: An image signal amplifying circuit comprising an amplifier and a gain control circuit. The amplifier respectively amplifies a first image signal and a second image signal, which are generated by a pixel array of an image sensor, by a first analog gain and a second analog gain, wherein each one of pixel circuits of the pixel array comprises a first capacitor for generating the first image signal and a second capacitor for generating the second image signal, wherein a charge storage capacity of the first capacitor is smaller than a charge storage capacity of the second capacitor. The gain control circuit selectively adjusts the first analog gain or the second analog gain. Each one of the pixel circuits has a first conversion gain corresponding to the first capacitor and a second conversion gain corresponding to the second capacitor.

    Abstract: A data arrangement method includes following steps: obtaining pixel data of a plurality of first N-bit pixels of a picture; and storing the obtained pixel data of the first N-bit pixels in a plurality of M-bit storage units of a first buffer according to a block-based scan order of the picture. The picture includes a plurality of data blocks, and the block-based scan order includes a raster-scan order for the data blocks. At least one of the M-bit storage units is filled with part of the obtained pixel data of the first N-bit pixels, M and N are positive integers, M is not divisible by N, and the first N-bit pixels include at least one pixel divided into a first part stored in one of the M-bit storage units in the first buffer and a second part stored in another of the M-bit storage units in the first buffer.

    Abstract: A buffer write method for a buffer, including a plurality of M-bit storage units, has following steps: obtaining pixel data of a plurality of first N-bit pixels of a picture; calculating a corresponding start address of the buffer for the pixel data of the first N-bit pixels; and storing the first N-bit pixels of the picture according to the calculated start address of the buffer in the M-bit storage units by a buffer controller. The storing step includes fully storing at least one of the first N-bit pixels in one of the M-bit storage units storage units, wherein M and N are positive integers, and M is not divisible by N.

    Abstract translation: 包括多个M位存储单元的缓冲器的缓冲写入方法具有以下步骤：获得图像的多个第一N位像素的像素数据; 计算第一N位像素的像素数据的缓冲器的相应起始地址; 以及通过缓冲器控制器根据计算出的M位存储单元中的缓冲器的起始地址存储图像的第一N位像素。 存储步骤包括在M位存储单元存储单元之一中完全存储第一N位像素中的至少一个，其中M和N是正整数，M不能被N整除。
