Abstract
A memory control block performs in parallel a process of writing a current frame of image data captured by an image capturing device into a system shared memory, a process of reading out a previous frame of image data stored in the system shared memory, and a process of writing combined image data generated in an image combining block into the system shared memory.
Claims18
A wide dynamic range image capturing apparatus comprising:
- an image capturing device for capturing image data having an electric charge accumulation period varying every a frame;
- a preprocess block for performing DC adjustment, gain adjustment, and gamma characteristics adjustment with respect to the image data;
- a data storage memory for storing the image data;
- a memory control block for controlling a write or read operation of the image data with respect to the data storage memory;
- an image combining block for performing a combining operation process with respect to two frames of image data having the different electric charge accumulation periods to generate combined image data;
- and
- an image processing block for performing video signal processing with respect to the combined image data,
- wherein the memory control block can perform in parallel a process of writing a current frame of image data captured by the image capturing device into the data storage memory, a process of reading a previous frame of image data stored in the data storage memory, and a process of writing the combined image data generated in the image combining block into the data storage memory.
