An image processing apparatus for performing processing that rounds down C bits from an A-bit image, and that causes a B=(A&#x2212;C) bit image resulting from the rounding down processing to be displayed comprises a time dithering unit configured to express a pixel value that is an intermediate value of one step in the (A&#x2212;C) bits in the A-bit image by selectively outputting in each frame across N frames a value where the intermediate value was rounded down and a value where the intermediate value was rounded up, and to artificially express the A-bit image with a dither pattern where the N frames is a minimum unit, wherein the time dithering unit sets the value of N so that M/N is 25 or more.

Image processing apparatus, image display system, image processing method having a time dithering process

An electronic apparatus provided with a display unit configured to display image data, comprises a synchronization control unit that generates a synchronization signal based on a display rate of the display unit, and an image processing unit that operates in accordance with an operating clock and execute image processing on image data to be displayed on the display unit at a display rate synchronized with the synchronization signal. The operating clock is not changed when the synchronization control unit changes a period of the synchronization signal in accordance with a change in a display rate of the display unit.

Electronic apparatus, method for controlling same, and computer readable medium

An image processing apparatus that inputs an image, detects a pixel value of each pixel of an input image and obtain at least one of a maximum value, a minimum value, and an average value of pixel values for each of predetermined sections of the input image, generates a first image indicating a frequency of pixel values of the input image, where a position of a pixel and a pixel value are associated, generates a second image in which additional information including at least one of the maximum value, the minimum value, and the average value is superimposed on the first image, and superimposes the second image on the input image and display the result.

Image processing apparatus and image processing method

An image capturing apparatus, comprises a detector configured to detect a focus adjustment position in an image, a processor configured to generate a composite image in which a guide indicating the detected position is superimposed on the image, a display configured to display the composite image generated by the processor, and a controller configured to update, in accordance with information of the position detected by the detector, display information used for processing for generating the composite image.

Image capture apparatus and control method thereof

An image processing apparatus capable of making a user confirm effect of HDR reliably. An acquirer acquires a luminance component of an input image. A converter converts the luminance component acquired by the acquirer into a predetermined luminance value for each pixel. A generator generates a graph waveform image that shows a graph showing a distribution of the luminance values obtained through the conversion by the converter. A display controller displays the graph waveform image generated by the generator on a display unit. When the input image is recorded in a first mode, an axis representing the luminance values in the graph is a logarithmic axis, and the generator generates a logarithmic graph waveform image showing the distribution of the luminance values based on the logarithmic axis.

Image processing apparatus configured to generate auxiliary image showing luminance value distribution, method for controlling the image processing apparatus, and storage medium

An image capturing apparatus which captures an image of a subject with an image sensor having pixels each including a plurality of areas and generates a RAW image for each of the plurality of areas from a signal generated by the image sensor. The apparatus generates a first RAW image and a second RAW image from the RAW images, generates first image data by performing first development on the first RAW image, generates first RAW image data and second RAW image data by compressing the first RAW image and the second RAW image and performs second development on the first RAW image having a higher processing load than the first development. Second image data is generated by the second development on the first RAW image by using the second RAW image.

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

An image pickup apparatus that is capable of reducing degradation of image quality of the whole display screen of a display section while improving display delay with respect to an observed area. In an image pickup apparatus, an image pickup section picks up an image of an object, and a development processor generates image data by developing input data acquired by the image pickup section. A first image generation unit generates a first image by performing image processing on part of the image data. A second image generation unit performs predetermined image processing on the image data to thereby generate a second image which is different in the number of steps of image processing from the above image processing. An image synthesis section generates a third image by synthesizing the first image with the second image, and a display device displays the third image.

Image pickup apparatus equipped with display section and method of controlling the same

An image pickup apparatus includes a first image reduction unit configured to reduce the size of an image output by an image pickup element, a memory configured to store the image reduced by the first image reduction unit, an external output unit configured to output the image stored in the memory, a display configured to display an image being shot, a second image reduction unit configured to reduce, to the display size on the display, the image reduced by the first image reduction unit, without causing the reduced image to be stored in the memory and a signal processor for the display configured to perform signal processing of the image reduced to the display size on the display.

Image signal processing apparatus and a control method thereof, and an image pickup apparatus and a control method thereof

An image signal processing apparatus converts an input image signal such that the number of pixels in the horizontal direction is converted into 2n pixels, to store the thus-converted into a memory, samples the pixels of the stored image signal in accordance with a predetermined pixel arrangement of a display apparatus to convert the number of pixels in the horizontal direction into n pixels and convert the number of pixels in the vertical direction into m pixels, subsequently converts the image signal converted into n&#xd7;m pixels into a plurality of color component signals corresponding to the pixels of the display apparatus, further, corrects a center of gravity in accordance with the predetermined pixel arrangement of the display apparatus to output the corrected signals to the display apparatus.
