Abstract: An image sensor includes: a light detector including a plurality of photosensitive cells configured to sense light; a color separation lens array provided above the light detector and including a plurality of pattern structures, the color separation lens array being configured to collect light having different wavelength spectra respectively on at least two photosensitive cells of the plurality of photosensitive cells; and a variable interlayer element configured to adjust an optical distance between the light detector and the color separation lens array.

Abstract: A scroll compressor is provided. The scroll compressor may include a valve and a valve spring accommodated in a housing as one module, and the housing may be directly coupled to a fixed scroll. This may simplify assembly processes of the scroll compressor. Further, a sealing recess that communicates with a middle pressure chamber may be formed at the housing, thereby forming a damping space between a high pressure space and a low pressure space. This may prevent lowering of performance of the scroll compressor due to leakage of refrigerant inside the high pressure space to the low pressure space in a normal driving mode.
