A control apparatus includes an acquiring unit configured to acquire information about three-dimensional space obtained using a distance measuring unit and information about a three-dimensional figure specified by a user, a determining unit configured to determine a search area based on the information about the three-dimensional space and the information about the three-dimensional figure, and a control unit configured to automatically control an angle of view so that a main object in the search area is included in an imaging angle of view.

Control apparatus, image pickup apparatus, control method, and storage medium

An image capturing apparatus comprises an image sensor, and a controller that controls the image sensor to shoot images for display at a first cycle and controls to shoot a still image in response to the image shooting instruction. In a case where continuous shooting of still images is instructed during shooting the images for display at the first cycle, the controller changes a cycle at which the images for display are shot to a second cycle which corresponds to an integer multiple of speed of the continuous shooting while e continuous shooting is performed, and controls the image sensor to shoot the still images at the speed of the continuous shooting and shoot the images for display at the second cycle.

Image capturing apparatus and control method thereof

An image capture apparatus comprising an image sensor is disclosed. When an instruction to shoot a still image has been detected when executing a live view display, the image capture apparatus shoots the still image preferentially, while repeatedly displaying a same image during a period in which the live view display cannot be updated. The image capture apparatus reduces a luminance and/or changes a tone of the image that is repeatedly displayed.

Image capture apparatus and control method thereof

An image capturing apparatus comprising an image sensor and a control circuit is disclosed. The control circuit changes, if a second drive period that is a drive period of the image sensor for still image shooting overlaps with a first drive period that is a drive period of the image sensor for moving image shooting, a start timing of the second drive period. When performing still image shooting while performing moving image shooting and moving image display: if the still image shooting is single image shooting or a first shot of continuous shooting, the control circuit does not change the start timing of the second drive period. If the still image shooting is a second shot onward of continuous shooting, the control circuit changes the start timing of the second drive period with giving priority to the moving image display.

A coding apparatus for coding a frame of a moving image on a block basis includes a calculation unit configured to, for a block adjoining the target block and having a motion vector to be used for coding having been selected, from among blocks in the frame, calculate a difference between a detected motion vector and a motion vector of the target block and calculate a difference between pixels of a reference block identified by applying a motion vector of the adjoining block to the target block and pixels of the target block, a determination unit configured to determine whether a motion vector to be used for coding the adjoining block has been detected at the time of processing, and a motion vector selection unit configured to, based on a calculation result and a determination result, select a motion vector to be used for coding the target block.

Coding apparatus, coding method, and recording medium

In a motion detecting apparatus which can perform a high-accuracy motion search with a less calculation cost, it is discriminated whether or not input Activity and DIFF_XORSUM values are smaller than respective predetermined thresholds. If the Activity value is smaller than the threshold or the DIFF_XORSUM value is smaller than the threshold, a reference vector is selected as a motion vector. On the other hand, if the Activity value is equal to or higher than the threshold and the DIFF_XORSUM value is equal to or higher than the threshold, an N-valued image search vector is selected as the motion vector.

Motion detecting apparatus, motion detecting method and program

For each of respective viewpoints, the capturing condition at the viewpoint, and each frame image captured from the viewpoint in accordance with the capturing condition are acquired. One of the viewpoints is selected as a reference viewpoint by using the acquired capturing conditions. Predicting coding and intra-coding are performed for the acquired images. For each of the respective viewpoints for each frame, the coding result of the frame image captured from the viewpoint by predicting coding or intra-coding is output. When performing predicting coding for an image captured from the reference viewpoint, predicting coding is performed by referring to the image captured from the reference viewpoint without referring to images captured from the viewpoints other than the reference viewpoint.

Image processing apparatus and image processing method

A specific region in each frame image input after a detection process has been completed a predetermined number of times or more is estimated from a specific region detected from a past frame before the frame. The shift between the specific region detected from a first frame image input after the detection process has been completed the predetermined number of times or more and the specific region estimated for the first frame image is obtained. When the shift falls within a predetermined range, an encoding parameter to encode the specific region estimated for a second frame image input at a point the detection process for the first frame image has been completed with a higher image quality than that of regions other than the specific region is set.

Using scan conversion processing of changing the scan order for each block, parallel scan conversion processing is executed if possible. A scan status holding unit holds statistical information based on the appearance frequency values of coefficients in a block. A scan order holding unit holds coefficient position information in which the coefficient positions in a block are arranged based on the scan order. A significant data position information generation unit scans one block data in accordance with coefficient position information, and generates information representing nonzero/zero for each data position. Based on the statistical information and the information generated by the significant data position information generation unit, a parallel number determination unit determines whether to process two blocks in parallel or process one block. In accordance with the determination, a scan conversion unit scan-converts two input blocks in parallel or scan-converts only one of the blocks.

In a coding apparatus for performing motion-compensated coding, N (M&#x3e;N&#x2267;2)-arized images are converted from a coding target image and reference image as M-arized images, and a motion search is conducted using the N-arized images. During this process, the coding apparatus applies low-pass filter processing to the coding target image and the reference image before conversion of the N-arized images.
