Abstract

Systems and media to capture a digital image are disclosed. Embodiments include hardware and/or software for taking multiple color data readings with a series of sensing elements in one collecting location during a single exposure, associating the collecting location with a pixel, and calculating a color value for the pixel based on the multiple color data readings. The hardware or software may also direct light successively to the sensing elements of the series of sensing elements within one exposure via reflective optics, and may determine that a sensing element of the series of sensing elements is defective. The hardware or software may redirect light to align a non-defective sensing element of the series of sensing elements with the collecting location. The non-defective sensing element and the defective sensing element may be associated with the same color.

Claims

exact text as granted — not AI-modified
1 - 7 . (canceled) 
   
   
       8 . A machine-readable medium containing instructions, which when executed by a machine, cause said machine to perform operations, comprising:
 taking multiple color data readings with a series of sensing elements in one collecting location during a single exposure, wherein the taking comprises directing light successively to the sensing elements of the series of sensing elements within one exposure, the directing via reflective optics;   determining a sensing element of the series of sensing elements is defective, wherein the sensing element is associated with a color;   redirecting light to align a non-defective sensing element of the series of sensing elements with the one collecting location, wherein the non-defective sensing element is associated with the color;   associating the one collecting location with a pixel position in an image to be portrayed; and   determining a color value for the pixel position in the image based on the multiple color data readings.   
   
   
       9 . (canceled) 
   
   
       10 . The machine-readable medium of  claim 8 , wherein the instructions, which when executed by a machine, cause said machine to perform the taking comprise instructions, which when executed by a machine, cause said machine to perform taking multiple color data readings with more than one sensing elements, wherein the more than one sensing elements comprise color filters selected from a group of color filters comprising red, green, blue, cyan, orange, yellow, magenta, or clear. 
   
   
       11 - 12 . (canceled) 
   
   
       13 . A device, comprising:
 a series of sensing elements in one collecting location, adapted to collect multiple color data readings to determine a color value for a pixel in an image   reflective optics to redirect light to the series of sensing elements successively within one Exposure; and   logic to determine that a light sensor of the plurality of light sensors is defective, the light sensor associated with a color, wherein the reflective optics is to redirect light to align a non-defective sensing element of the series of sensing elements with the one collecting location, wherein the non-defective sensing element is associated with the color.   
   
   
       14 . The device of  claim 13 , wherein the series of sensing elements comprises a first element sensitive to red light, a second element sensitive to blue light, and a third element sensitive to green light. 
   
   
       15 . The device of  claim 13 , wherein the reflective optics comprise a digital micromirror device and control circuitry to redirect the light to the series of sensing elements successively within the one exposure. 
   
   
       16 . The device of  claim 13 , wherein the reflective optics include a mirror to scan light to the series of sensing elements. 
   
   
       17 - 21 . (canceled) 
   
   
       22 . The machine-accessible medium of  claim 8 , wherein the instructions, which when executed by a machine, cause said machine to perform determining a color value comprise instructions, which when executed by a machine, cause said machine to perform calculating the color value with at least one of the multiple color data readings. 
   
   
       23 . The machine-accessible medium of  claim 8 , wherein the instructions, which when executed by a machine, cause said machine to perform directing comprise instructions, which when executed by a machine, cause said machine to perform directing light to the series of sensing elements successively within one exposure, the directing via a digital micromirror and control circuitry.
