Imaging apparatus, imaging element, and image processing method
First Claim
1. An imaging apparatus comprising:
- an imaging element having a pixel group that is two-dimensionally-arranged, wherein the pixel group includes color pixels each having a color separating filter that transmits a specific color and non-color pixels that do not have the color separating filter; and
a first brightness information producing unit that produces a first brightness information of a pixel in the pixel group, wherein the first brightness information producing unit produces the first brightness information based on an electric signal converted by a photoelectric converting unit of the pixel when the pixel is the non-color pixel, and produces the first brightness information based on the electric signal converted by the photoelectric converting unit of the pixel and an electric signal converted by photoelectric converting units of the non-color pixels surrounding the pixel when the pixel is the color pixel.

Abstract
An imaging element includes a pixel group that has pixels arranged two dimensionally therein, each including a photoelectric converting unit. The pixel arrangement of the pixel group is m rows by n columns. In the pixel group, a pixel area of an arbitrary two rows by two columns respectively includes a red pixel, a green pixel, a blue pixel and a non-color pixel. A red color signal for a given red pixel is a signal value obtained from the pixel. A green signal for the red pixel is obtained by averaging the signal values of two green pixels adjacently on the right and the left of the pixel. A blue signal for the red pixel is obtained by averaging the signal values of four blue pixels adjacently on the upper-right, the upper-left, the lower-right, and the lower-left of the pixel.

13. An imaging apparatus comprising:
-
an imaging element having a pixel group that is two-dimensionally-arranged and includes color pixels each having a color separating filter that transmits a specific color; and
non-color pixels that do not have the color separating filter;
a color signal calculating unit that calculates a color signal of a pixel in the pixel group; and
a brightness information producing unit that produces a brightness information of the pixel based on the color signal, wherein the color signal calculating unit calculates the color signal of the pixel based on electric signals converted by photoelectric converting units of the pixel and the color pixels surrounding the pixel when the pixel is the color pixel, and calculates the color signal of the pixel based on the electric signals converted by the photoelectric converting units of the color pixels surrounding the pixel when the pixel is the non-color pixel. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
