According to one embodiment, a camera module includes an imaging device, a liquid crystal panel having an incident light control area, and a lens. The liquid crystal panel has a plurality of electrodes located in the incident light control area. The imaging device acquires information of light transmitted through the incident light control area of the liquid crystal panel and the lens.

According to one embodiment, a louver includes a first transparent substrate, a first organic insulating film provided on an inner surface side of the first transparent substrate, and including a first inclined surface and a second inclined surface, a first reflective layer provided along the first inclined surface, and a second reflective layer provided along the second inclined surface. The first reflective layer includes a first reflective surface. The second reflective layer includes a second reflective surface. An interval between the first reflective surface and the second reflective surface increases with distance from the first transparent substrate.

A data security apparatus includes an analog component. The analog component operates internally with a high degree of entropy. This high degree of entropy resides in the interactions between its internal components in response to an external driving signal. The interactions within the analog component have a level of entropy that is high enough to make digital simulation of the analog component impractical. Because the analog component is impractical to digitally simulate it is referred to as being digitally unclonable. The data security apparatus processes data by encrypting plaintext data into ciphertext and/or decrypting data from ciphertext into plaintext. Part of the conversion between plaintext and ciphertext uses the analog component. Since the analog component is digitally unclonable (that is, impractical to digitally simulate), the part of the conversion process that uses the analog component requires possession of the analog component itself or the possession of another analog component that has the same signature.

A composite lens system may include one or more first optical elements configured to provide a first focal length selected from a first continuous range of focal lengths, as well as one or more second optical elements configured to provide a discrete focal length selected from a plurality of discrete focal lengths. The one or more first optical elements and the one or more second optical elements may be configured in series such that the composite lens system provides an output focal length based on a combination of the selected first focal length and the selected discrete focal length.

Methods, apparatus, and systems for mitigating pinhole defects in optical devices such as electrochromic windows. One method mitigates a pinhole defect in an electrochromic device by identifying the site of the pinhole defect and obscuring the pinhole to make it less visually discernible. In some cases, the pinhole defect may be the result of mitigating a short-related defect.

Provided is a light absorption anisotropic film capable of preparing an image display device having excellent display performance and excellent durability, and a laminate and an image display device formed of the light absorption anisotropic film. The light absorption anisotropic film is used for an image display device, which is formed of a liquid crystal composition containing a liquid crystal compound and a dichroic substance, in which in a signal derived from the dichroic substance detected by time-of-flight secondary ion mass spectrometry, a relationship between a maximum intensity Imax of the light absorption anisotropic film in a thickness direction and an intensity Isur1 in a surface of the light absorption anisotropic film on a viewing side of the image display device satisfies Expression (I-1) 2.0≤Imax/Isur1.
