Abstract
An image acquisition device includes a single sensor having organic photodetectors, an angular filter, and a color filter. The color filter has one or a plurality of first portions adapted to give way to at least one wavelength in the visible range, and one or a plurality of second portions filtering wavelengths outside of red and/or near infrared. The second portion has a surface area approximately equal to a surface area of one of the photodetectors or a surface area greater than or equal to the surface area of four of the photodetectors.
