An image sensor that output a signal for detecting a focus state of a photographing lens. The image sensor includes a microlens; a light-receiving pixel; a first focus state detection pixel pair for outputting a focus state detection signal, in which aperture areas of the first focus state detection pixel pair are small in comparison to the light-receiving pixel; and a second focus state detection pixel pair for outputting a focus state detection signal, in which aperture areas of the second focus state detection pixel pair are small in comparison to the light-receiving pixel, wherein the second focus state detection pixel pair is arranged at a position that is shifted by a predetermined amount relative to each aperture position, with respect to the microlens of the first focus state detection pixel pair.

In an image sensor having a plurality of pixels which photoelectrically convert a subject image, a plurality of pairs of focus detection pixels including first focus detection pixels (S) and second focus detection pixels (S) are arranged while being distributed. The layouts of the first focus detection pixel (S) and the second focus detection pixel (S) are switched in pairs of focus detection pixels adjacent in the focus detection direction. Focus detection is performed using image waveforms obtained from the first focus detection pixel (S) and the second focus detection pixel (S) whose layouts are switched. This reduces focus detection errors generated when the pixels included in the pairs of focus detection pixels receive light fluxes from different portions of the subject.

A first display region for displaying an optical image of an object and a second display region for displaying information are provided for a finder device. The first display region and the second display region can be observed at the same time through an eyepiece window. On the second display region, an electric image that is photoelectrically converted by an image pickup element is displayed. That reduces failures to take a shutter chance and enables a state of the captured image and auxiliary information to be checked.

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.
