IMAGE PROCESSING CIRCUIT AND OPERATION METHOD THEREOF

原文（中国語）

An image processing circuit is coupled to an image sensor and includes a first memory, a second memory, an image receiving circuit, and a memory access circuit. The image receiving circuit is configured to receive an image from the image sensor and store the image in the first memory. The memory access circuit is configured to write the image from the first memory into the second memory. When the image receiving circuit stores the image in the first memory, the image processing circuit operates in a low-speed mode, and when the memory access circuit writes the image from the first memory into the second memory, the image processing circuit operates in a high-speed mode. The first operating speed of the second memory in the low-speed mode is lower than the second operating speed of the second memory in the high-speed mode.
