A solid-state imaging apparatus includes an image pick-up section in which photosensitive devices are arranged in, e.g., a honeycomb G square lattice, RB full-checker pattern due to shifted pixels. Regions void of the photosensitive devices are assumed to be virtual photosensitive devices. A signal processing section generates data for the virtual photosensitive devices by using the data of surrounding photosensitive devices while attaching importance to accurate color reproduction and horizontal and / or vertical resolution. As a result, the number of pixel data are increased in a square lattice arrangement. Therefore, high quality image signals are readily achievable with a smaller number of photosensitive devices than conventional with a conventional apparatus. Interpolation can be executed with the high quality signals to the limit of resolution with an adequate circuit scale. The honeycomb arrangement guarantees the required size of the individual pixel and thereby the sensitivity of the entire apparatus while increasing yield on a production line. False colors particular to a single photosensitive portion can be reduced by, e.g., uniform interpolation. Particularly, when a digital camera is constructed by using an imaging apparatus including optics operable with a silver halide sensitive type of film, false colors can be reduced without resorting to an optical low pass filter.

A camera is capable of both silver-halide shooting, through which object images are recorded on silver-halide film, and video shooting, although its distance measurement device is placed substantially in the same way and its mirror box has substantially the same size as in ordinary single-lens reflex cameras. In this camera, a pellicle mirror splits the light flux having passed through a taking lens into a first light flux and a second light flux, and a rotatable mirror switches the subsequent path of the second light flux between the optical path for a third light flux and the optical path for a fourth light flux. The pellicle mirror, through its light flux splitting function, directs the first light flux to a silver-halide shooting system, and directs the second light flux to the rotatable mirror. The rotatable mirror, through its optical path switching function, either directs the third light flux to an optical viewfinder system, or directs the fourth light flux to a video shooting system.
