Abstract: estimação de intensidade usando matriz de sensor binário com limites que variam espacialmente. um aparelho inclui uma matriz que contém luz limite de sensores n de sub-difração, cada um tendo um limite de ativação de absorção de luz associado por comutar de um estado de reiniciação para um estado ativado, onde os valores de ativação de absorção de luz ficam dentro de uma faixa de valores. o aparelho inclui adicionalmente um processador conectado com uma memória que inclui um código de programa de computador, onde a memória e o código de programa de computador são configurados para, com o processador, fazer com que o aparelho, pelo menos, funcione estimando uma intensidade de luz que ilumina a matriz com base nas saídas elétricas da matriz.

Abstract: 36 Abstract The invention relates to forming an image using binary pixels. Binary pixels are pixels that have only two states, a white state when the pixel is exposed and a black state when the pixel is not exposed. The binary pixels have color filters on top of them, and the setup of color filters may be known to some degree. A setup making use of a statistical approach may be used to determine the color of incoming light to produce output images. Consequently, the approach may be used with the binary pixel array to produce images from the input images that the binary pixel array records.

Abstract: The invention relates to forming an image using binary pixels. Binary pixels are pixels that have only two states, a white state when the pixel is exposed and a black state when the pixel is not exposed. The binary pixels have color filters on top of them, and the setup of color filters may be initially unknown. A setup making use of a statistical approach may be used to determine the color filter setup to produce correct output images. Subsequently, the color filter information may be used with the binary pixel array to produce images from the input images that the binary pixel array records.

Abstract: An apparatus includes an array containing N sub-diffraction limit light sensors each having an associated light absorption activation threshold for switching from a reset state to an activated state, where the light absorption activation values lie within a range of values. The apparatus further includes a processor connected with a memory including computer program code, where the memory and computer program code are configured to, with the processor, cause the apparatus at least to perform estimating an intensity of light that illuminates the array based on electrical outputs of the array.
