PROBLEM TO BE SOLVED: To provide a solid-state imaging apparatus capable of balancing a color signal and a luminance signal with each other while keeping color pixels and white pixels equal in size. SOLUTION: A plurality of photodetecting elements PD which photoelectrically convert incident light to generate signal charges are arrayed in a two-dimensional matrix form in a semiconductor substrate 3. One of three kinds of R, G and B color filters 19a to 19c is disposed on an incident side of each of the photoedetecting elements PD arrayed in checkered pattern positions, and a first microlens 20a is disposed on each color filter to constitute a color pixel (R pixel, G pixel or B pixel). A second microlens 20b which has a lower peak position than the first microlens 20a is disposed on an incident side of each of photodetecting elements disposed in the remaining checkered pattern positions not with a color filter interposed therebetween to constitute a white pixel (W pixel). Consequently, the first microlens has a wider incident angle range to have improved efficiency of convergence of oblique incident light. COPYRIGHT: (C)2009,JPO&INPIT |
