Patent ID: 8570394

Claim:
A method, comprising: generating, by a computing device in a portable imaging device, a histogram comprising a first graph of input luminance values on an x-axis and output luminance values on a y-axis overlaid on a second graph of initial luminance values on the x-axis and a number of pixels on the y-axis associated with a plurality of pixels in an image prior to storage of the image in a memory device by activating a shutter switch; enabling adjustment of the second graph by adjusting the first graph; obtaining at least one target value from the adjusted second graph; generating, by the computing device, at least one control setting corresponding to at least one setting of the portable imaging device using the at least one target value; and capturing the image in the memory device using the at least one control setting by activating the shutter switch; wherein a body of the portable imaging device is configured to house the computing device or the memory device.
