1. An apparatus comprising:
- a two-dimensional solid state image sensor array comprising;
a monochrome subset of pixels comprising monochrome pixels that are devoid of wavelength selective filter elements and are adapted for use in generation of monochrome image data; and
a color subset of pixels comprising color sensitive pixels that include wavelength selective filter elements and are adapted for use in generation of color image data;
wherein the apparatus is adapted for generation of a frame of image data having pixel positions corresponding to the monochrome subset of pixels and pixel positions corresponding to the color subset of pixels; and
wherein for generation of the frame of image data having pixel positions corresponding to the monochrome subset of pixels and pixel positions corresponding to the color subset of pixels, the apparatus exposes the monochrome subset of pixels during a monochrome pixel exposure period for controlling exposure of the monochrome subset of pixels and exposes the color subset of pixels during a color pixel exposure period for controlling exposure of the color subset of pixels.

Abstract
A portable hand held optical reader having a specially constructed two-dimensional image sensor array is operational in a bar code decoding mode and in a picture taking mode. The specially constructed image sensor array, in one embodiment, is a hybrid monochrome and color image sensor pixel array, wherein a first subset of the pixels are monochrome pixels devoid of wavelength selective color filter elements and a second subset of the pixels are color sensitive pixels including wavelength selective color filter elements.
