This invention has as its object to provide an image sensing apparatus which can satisfactorily correct misregistration among images, and can composite the images. To achieve this object, an image sensing apparatus includes: a plurality of apertures that receives external light from different positions; a plurality of image sensing units that outputs image signals obtained by independently receiving light that comes from an identical position of an object and is received via the plurality of apertures, and independently extracting predetermined color components for each received light; and a signal processing device that forms a signal that outputs an object image by mixing the image signals output from the plurality of image sensing units. When it is determined that a predetermined position deviation occurs between the image signals upon forming the signal that outputs the object image, the signal processing device corrects the predetermined position deviation by a signal process, and forms the signal that outputs the object image.

An image processing apparatus comprises an image display unit for displaying a desired image in accordance with an image signal, and image pickup units disposed respectively on the left and right sides of the image display unit. An image picked up from the left side and an image picked up from the right side are displayed together to be synthesized as the desired image in an image display unit of, e.g., a terminal of a conversation partner. Display in eye-to-eye matching with the conversation partner is thereby realized. An image processing apparatus, such as a portable communication terminal, capable of realizing conversation in a natural eye-to-eye matching state with the conversation partner can be provided.

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.
