Description
Following is a sample of the information contained on this CD: FIELD OF INVENTION The present invention is in the field of color sensing. More particularly, the present invention relates to methods and arrangements to capture a digital image. BACKGROUND A digital image sensor is an integral part of several electronic systems including computers, cell phones, digital photography systems, robotics vision systems, security cameras, medical instruments, color matching applications and other color photosensitive devices. One digital image sensor, such as a TCS230 Programmable Color Light-to-Frequency Converter manufactured by TAOS, Inc., typically includes sensing elements, which may be sensitive to a broad range of frequencies of light. Some systems include lenses that are added and positioned on top of each sensing element to collect light and to make the sensing elements more sensitive. Adding color filters to light sensors on an image sensor to specifically be color sensing elements may capture the brightness of the light that passes through and provide color sensing for red, green, and blue, for example. Thus, with color filters in place, color sensing elements typically record only the brightness of the light that matches its filler and passes through it while other colors are blocked. For example, a pixel with a red filter senses the brightness of only the red light that strikes it. The color sensing elements appear in a photodiode grid consisting of groups of individual color sensing elements, each checkered throughout the grid on the same optical plane. For example, a group may include individual color sensing elements, for example, a red sensing element, a green sensing element, a blue sensing element, and sometimes a clear sensing element with no filter for intensity information. All of the photodiodes of the same color are typically connected in parallel. With the TCS230, the color selected for use during operation is dynamically
