There is provided an image processing device including an image acquisition part acquiring an image; a depth acquisition part acquiring a depth in association with a pixel included in the image; a target object detection part detecting a region of a predetermined target object in the image; a target object detection distance selection part selecting the depth corresponding to the pixel included in the detected region as a target object detection distance; a local maximum distance selection part selecting the depth having a local maximum frequency in a frequency distribution of the depths as a local maximum distance; and a determination part determining whether the image is a target object image obtained by shooting the target object depending on whether a degree of closeness between a value of the target object detection distance and a value of the local maximum distance is higher than a predetermined value.

Image processing device, method of controlling image processing device and program causing computer to execute the method

An apparatus includes a display control section configured to control display of image data for an image, the image data including flash reach information identifying at least one portion of the image corresponding to at least one region reached by light from a flash. Also described are a method and computer-readable storage medium for controlling display of image data for the image.

Image display using flash reach information

An imaging apparatus includes: an imaging optical system having an aperture; an imaging device that outputs an image signal; an electronic shading processing portion that adds an electronic shading to a photographic image corresponding to the image signal; and a control portion which determines whether or not an optical shading can be added to the photographic image based on the imaging condition, the control portion controlling the aperture and adding the optical shading when the optical shading can be added, and the control portion controlling the electronic shading processing portion and adding the electronic shading when it is difficult to add the optical shading.

Imaging apparatus and method of controlling imaging apparatus for adding a shading to an image

A simple compression and decompression method provides excellent effects by reducing the storage capacity of an image memory, while adapting to the properties of image. On the basis of luminance information extracted by a luminance extraction blocka compression conversion rule setting blocksets a compression conversion rule to a compression conversion tableIn accordance with this compression conversion rule, an image compression blockcompresses original image data and holds the compressed image data in an image memoryalong with a type of the compression conversion rule. This type of the compression conversion rule held in the image memoryis extracted by a decompression conversion rule setting blockIn accordance with this type, a decompression conversion rule is set to a decompression conversion tableIn accordance with the decompression conversion rule set to the decompression conversion tablean image decompression blockdecompresses the compressed image data held in the image memory

Image processing device

A high-frequency integrating circuitdetects characteristics of horizontal high-frequency components and vertical high-frequency components of the image formed by a processing-target image signal. Based on the detection result, a CPUobtains the number of bits of the after-compression-coding data of the image signal, and calculates the compression rate dependent upon the number of bits. The CPUcontrols an image codecso that the processing-target image signal is compression-coded through only one time of compression coding processing by use of the calculated compression rate. This configuration allows the image compression processing (compression coding) to be rapidly executed with high accuracy.
