Information processing apparatus, information processing method, information processing program, and mobile terminal

A signal processing device includes a memory which stores correction data in advance. The signal processing device modifies the correction data stored in the memory on the basis of an image sensing signal obtained by causing an image sensing unit to perform image sensing operation in a non-exposure state. The signal processing device corrects by using the modified correction data an image sensing signal obtained by causing the image sensing unit to perform image sensing operation in an exposure state.

Image data correction processing based on sensitivity

A detection error of foreign substance due to the presence of a newly generated defective pixel can be considerably prevented. An image pickup apparatus includes a foreign substance detector detecting foreign substance adhering to an optical member arranged on a light axis for image capturing in accordance with an image signal obtained by the image pickup device, a defective pixel position detector detecting a position of a defective pixel in the image pickup device in accordance with an image signal obtained by the image pickup device, a storage unit storing position information detected by the defective pixel position detector, and a controller controlling processing so that the foreign substance detector detects the foreign substance after the defective pixel position detector detects the position of the defective pixel.

Image pickup apparatus

An image capturing apparatus includes an image capturing unit which converts an optical image of an object into an electrical signal, and an optical member arranged on the object side of the image capturing unit. The image capturing apparatus also includes an alien substance removing unit configured to execute an alien substance removal operation to remove alien substances adhering to the surface of the optical member, an environmental condition detection unit configured to detect the environmental condition around the image capturing unit or around the optical member, and a control unit configured to control the alien substance removal operation on the basis of the detected environmental condition.

Image capturing apparatus, control method thereof, and program

An active-type multipoint automatic focusing apparatus is arranged to vary the number of distance measuring points according to focal length, and to vary, according to the number of distance measuring points varied, the number of times of light projection to be made by a light projecting part for a distance measuring action at each of the distance measuring points.

Distance measuring device

When performing distance measuring operation in an active mode, a charging time is compared to a predetermined period, and if the charging time is shorter than the predetermined period, then it is determined that the object is at a short distance, whereas, if the charging time is longer than the predetermined period, then it is determined that the object is in the distance. Since the positions where images of an object are formed on sensors depend upon the distance to the object, in other words, the phase difference between the images of the object depends upon the distance to the object, when the object is in the distance, the correlation operation is performed in a shift range corresponding to the long distance, whereas, when the object is at a short distance, the correlation operation is omitted in a shift range corresponding to the long distance and the correlation operation is performed in a range corresponding to a short distance.

Distance measuring apparatus and method

A distance measuring apparatus for a camera includes light-projecting means for projecting a light beam onto an object of distance measurement, and a pair of sensor arrays, each including a plurality of pixels located at respective pixel positions for receiving reflected light of the light beam reflected by the object of distance measurement and outputting a signal corresponding to the amount of reflected light received. The apparatus further includes phase difference detection means for detecting a phase difference between signals output from the pair of sensor arrays, distance measuring means for measuring a distance to the object on the basis of the phase difference, and shortest range discrimination means for discriminating whether the object of distance measurement is in a shortest range, on the basis of levels of maximum values of signals output by said pair of sensor arrays, where the shortest range is a distance or range at which photography can not be performed.

Distance measuring apparatus

Disclosed is a distance measuring apparatus for measuring the distance to an object on the basis of reflected light obtained as a result of projecting light onto an object, in which different reliability or contrast discrimination values are set in active and passive distance measurements. When the distance to the object is calculated by performing a correlation calculation on the basis of two received-light images obtained by an active or passive distance measurement, the reliability of the calculated distance and contrast values of the two received-light images are discriminated using the discrimination value.
