A screw compressor includes a screw rotor, a casing, and a fluid supply portion to supply fluid in a membrane form into a compression chamber in the casing. The screw rotor has a male and female rotors. A male bore covering the male rotor and a female bore covering the female rotor are formed on the inner surface of the casing. An intersection line, on a higher pressure side, of the male and female bores is defined as a compression cusp. In a bore development view, a trajectory made by the first intersection of an extension line of a female lobe ridge and a male lobe ridge being moved, along with the rotation of the male and female rotors, is defined as a trajectory line. An opening of the fluid supply section to the compression chamber is positioned between the compression cusp and the trajectory line.

An imaging apparatus is capable of allowing a user of the apparatus to execute a photographing setting for implementing an expression of a photograph with the finishing requested by the user and for achieving a quality of an image which the user requested with a wide variety of expression ambiences even if the user is not very conversant with digital image processing. The user selects and executes three settings, such as the type of a scene to be photographed, a state of an object to be photographed, and a finishing. The photographing conditions and image processing parameters are set and executed in interlock with the selected settings. As a result, the imaging apparatus can implement the finishing of a photograph desired by the user.

An object of this invention is to perform, for a photographed image, image processing which reflects the intention of the user without photographing again. In order to achieve this object, photographing data from an image sensor is temporarily stored in a memory, and an image of the photographing data as a result of digital development processing is displayed. When it is determined from the displayed image that the parameters of various image processes in digital development processing are not proper for the photographed image, the parameter settings are corrected again. Then, operation of reading out photographing data from the memory and performing digital development processing again is executed a necessary number of times. When an image quality intended by the photographer is obtained, the photographing data is recorded on a recording medium.

A first white balance correction amount is calculated according to similarity between image data acquired by an image pickup unit and past image data acquired in the past, and a first white balance correction is performed on the image data according to the first white balance correction amount. A luminance correction amount and a color correction amount are calculated according to similarity between the corrected image data and the past image data corrected in the first white balance correction. Using one of them, the first white balance correction amount is corrected thereby to obtain a second white balance correction amount. According to the obtained correction amount, a second white balance correction, a luminance correction, and a color correction are performed on the image data acquired by the image pickup unit.
