A method for optically recording impressions of areas of skin, through which blood flows, of a plurality of human autopods or parts thereof, wherein - at least one area of skin, of which an impression is to be taken, is approached to and placed on a placement surface of a device for taking such impressions, - a plurality of light-emitting elements (8, 13), which are arranged in a grid-like manner in a second pixel grid and can be controlled individually or in groups, are switched on or off for illuminating the at least one area of skin, - the light emitted by the light-emitting elements (8, 13) is directed through a layered body containing a sensor layer with light-sensitive sensor elements of predetermined lateral dimensions arranged in a first pixel grid, a spectral filter and through the placement surface onto and into the at least one area of skin, where the light is deflected depending on the nature and position of the area of skin and, if necessary, is coupled out again in the direction of the placement surface, is directed through the placement surface and the spectral filter onto the light-sensitive sensor elements and there the intensity of the light is registered, - wherein the spectral filter is configured as a high-pass filter with a cut-off wavelength predetermined as a function of the optical absorption behaviour of the areas of skin through which blood flows and being at least partially transparent to light emitted by the light-emitting elements (8, 13), and - has filter elements, each individual filter element being placed exactly above a corresponding light-sensitive sensor element, - wherein the distance of each light-sensitive sensor element from the placement surface is less than the pixel pitch of the first pixel grid, - from intensity values determined by the light-sensitive sensor elements, at least the position, shape and/or contact pressure of the at least one area of skin on the placement surface is determined as a result via image processing algorithms, - depending on the determined result, the light-emitting elements (8, 13) are controlled and switched on or off or their colour values and/or brightness are changed, and visual information is displayed by the light-emitting elements (8, 13) which is displayed on the placement surface. - at least one area of skin, of which an impression is to be taken, is approached to and placed on a placement surface of a device for taking such impressions, - a plurality of light-emitting elements (8, 13), which are arranged in a grid-like manner in a second pixel grid and can be controlled individually or in groups, are switched on or off for illuminating the at least one area of skin, - the light emitted by the light-emitting elements (8, 13) is directed through a layered body containing a sensor layer with light-sensitive sensor elements of predetermined lateral dimensions arranged in a first pixel grid, a spectral filter and through the placement surface onto and into the at least one area of skin, where the light is deflected depending on the nature and position of the area of skin and, if necessary, is coupled out again in the direction of the placement surface, is directed through the placement surface and the spectral filter onto the light-sensitive sensor elements and there the intensity of the light is registered, - wherein the spectral filter is configured as a high-pass filter with a cut-off wavelength predetermined as a function of the optical absorption behaviour of the areas of skin through which blood flows and being at least partially transparent to light emitted by the light-emitting elements (8, 13), and - has filter elements, each individual filter element being placed exactly above a corresponding light-sensitive sensor element, - wherein the distance of each light-sensitive sensor element from the placement surface is less than the pixel pitch of the first pixel grid, - from intensity values determined by the light-sensitive sensor elements, at least the position, shape and/or contact pressure of the at least one area of skin on the placement surface is determined as a result via image processing algorithms, - depending on the determined result, the light-emitting elements (8, 13) are controlled and switched on or off or their colour values and/or brightness are changed, and visual information is displayed by the light-emitting elements (8, 13) which is displayed on the placement surface.
