An image processing apparatus can execute appropriate image processing while preventing increase in a capacity of a memory for storing a plurality of pieces of image data of different frequency bands. The image processing apparatus stores first image data having the highest frequency among the plurality of pieces of image data of different frequency bands in a state in which each pixel of the first image data includes a color component signal of any of a plurality of colors, on the memory, and further stores second image data and third image data whose frequency bands are lower than that of the first image data on the memory, in a state in which a part of or all pixels of the second and the third image data have color component signals of a plurality of colors.

Apparatus and method for image processing using color image data and low frequency image data

Disclosed is a video signal processing apparatus applicable to various LCD panels. This video signal processing apparatus includes a format converting unit which converts first-format image data into second-format image data, a point sequential converting unit which converts the second-format image data into point sequenced data, a resizing unit which resizes the point sequenced data, a line memory which stores the resized point sequenced data, and an output control unit which controls to continuously read out the point sequenced data from the line memory.

Video signal processing apparatus, video signal processing method, and imaging device

When a first display device displays image data, a display control apparatus reserves a memory space having the first horizontal pixel number in the storage unit, and sets the frequency of a clock signal supplied to the display control unit to a first frequency. When a second display device displays image data, a display control apparatus reserves a space of the second horizontal pixel number, which is higher than the first horizontal pixel number, and sets the frequency of a clock signal supplied to the display control unit to a second frequency which is higher than the first frequency.

Display control apparatus, and setting method and program for display control apparatus

In an image capturing apparatus with an operation mode for carrying out expression detection, it is determined whether or not the image capturing apparatus is operated in the operation mode for carrying out expression detection. In a case in which the image capturing apparatus is operated in the operation mode for carrying out expression detection, setting in such a way that images with a resolution higher than in a case in which the image capturing apparatus is not operated in the operation mode are read out from an image sensor allows the expression of a face of a person to be detected efficiently.

Image capturing apparatus and control method therefor

An image sensing apparatus comprises an image sensing unit configured to sense an object and generate image data, a face detection unit configured to detect a face region of a person contained in the image data generated by the image sensing unit, and a facial expression determination unit configured to determine a plurality of facial expressions in the face region determined by the face detection unit. When both a first facial expression and a second facial expression are determined, the facial expression determination unit corrects a condition to determine the second facial expression so as to become difficult as compared to the determination condition when the first facial expression is not determined and the second facial expression is determined.

Image sensing apparatus, image capturing method, and program related to face detection

An image processing apparatus comprises: a feature detection circuit adapted to detect a feature portion of an object from a sensed image; a blur amount detection circuit adapted to detect a blur amount, during image sensing, of a device adapted to obtain the sensed image; a display unit adapted to display the sensed image, and display a frame surrounding the feature portion of the object in the displayed sensed image; and a calculation circuit adapted to set a position, in the sensed image, of the frame surrounding the feature portion of the object, wherein the calculation circuit calculates, on the basis of the blur amount, a moving amount of the frame whose position in the sensed image is set on the basis of the feature portion detected by the feature detection circuit.

Image processing apparatus, image sensing apparatus, and control method of image processing apparatus

An image capturing apparatus having an auto focus function or an auto exposure function stores digital image data output from an A/D conversion unit as first image data directly or after performing predetermined processing, and stores the digital image data serving as a base of the first image data as second image data after performing predetermined processing for the digital image data. The apparatus then detects a face region from the second image data, and displays the image on the basis of the image data output from the A/D conversion unit while the face region is detected form the second image data. After completion of detection of the face region from the second image data, the apparatus extracts information for auto focus, auto exposure, or white balance by using, of the first image data, data at a portion corresponding to the face region that is detected by said face detection means, and performs auto focus control, auto exposure control, or white balance control.
