Abstract: The invention provides an ambient light sensing device which receives at least one visible light image sensed by an image sensor. The ambient light sensing device includes an image sampling unit and an analyzing unit. The image sampling unit divides the visible light image into plural image blocks, extracts at least one sample data in each image block, and generates a comparison data according to a difference between the sample data extracted at different time points. The analyzing unit analyzes the comparison data and generates an output analysis signal accordingly.

Abstract: The present invention discloses a thermal pile sensing structure integrated with one or more capacitors, which includes: a substrate, an infrared sensing unit and a partition structure. The infrared sensing unit includes a first and a second sensing structure. A hot junction is formed between the first and the second sensing structures at a location where the first and the second sensing structures are close to each other. A cold junction is formed between the partition structure and the first sensing structure at a location where these two structures are close to each other. Another cold junction is formed between the partition structure and the second sensing structure at a location where these two structures are close to each other. A temperature difference between the hot junction and the cold junction generates a voltage difference signal. Apart of the partition structure forms at least one capacitor.
