Disclosed herein is an image processing apparatus having a memory to store taken image data, for effecting image processing on the stored image data, including: an image data storage control section for outputting block data end signals indicating data end of blocked image data in synchronization with the storing of the taken image data into the memory; and an image processing section having a stored a mount counting section for counting amount of the taken image data stored into the memory based on the block data end signals, and a processing progress control section for controlling the progress of the image processing based on the stored a mount counted at the stored amount counting section.

Image processing apparatus

An electronic camera device according to the first aspect of the present invention comprises a battery which supplies a power supply, a detector which detects a state of the power supply of the loaded battery, a flash device configured to illuminate a subject, a charge controller which controls a charge processing of charging an energy supplied to the flash device, a processing part which executes at least one processing requiring an electric power more than a predetermined value except a charge processing, and a part configured to execute the charge processing and at least one processing each unit of a predetermined processing by timesharing while keeping the electric power supplied by the battery to maximum.

Electronic camera apparatus

An automatic exposure ('AE'), control apparatus to prevent exposure errors resulting from 'smear.' Image-capturing is performed at a single exposure time TI (I=1, 2, . . . n); a CCD output is applied with a CCD drive signal to perform an integrating operation for a signal in an AE area using an integration circuit, and then outputs integration value EI+SI at each exposure time. A shutter trigger operation presents readout of an exposure value. An integrator value En+Sn obtained just before the shutter trigger operation, and a smear value Sn' obtained just after the shutter trigger operation are provided to an exposure operation/control circuit. The exposure operation/control circuit then performs an AE operation to receive En+Sn&#x2212;Sn&#x2248;En and compares the value to a target value for determining exposure conditions, and provides an AE operation value containing almost no smear component to determine an appropriate exposure condition.

Automatic exposure control apparatus and method

An interpolation calculation circuit for improving the image quality for recording and display is provided. The interpolation calculation circuit interpolates a necessary pixel on the basis of interpolation calculation (cubic interpolation processing) by an approximate expression of an interpolation coefficient of at least 3rd-order. This cubic interpolation processing is applied to basic processing of an electronic camera, i.e., 3-CCD processing, format conversion, and image enlargement/reduction. In consideration of the operation load on the electronic camera, cubic interpolation processing is performed in accordance with the image sensing mode or the like only when it is necessary, thereby controlling whether execution of interpolation processing is enabled/disabled.

Electronic camera

An electronic imaging system includes a CCD image sensor arrangement having a two dimensional array of pixels. The pixel array converts light incident thereon to an electric signal. The pixels are arranged in a plurality of horizontal rows or lines, the lines being arranged vertically. A control arrangement selectively controls operational modes of the system. One mode provides for sequential scan reading out of pixel signals for entire lines of the CCD for still picture recording. Another mode provides for reading out pixel signals concerning k (k is a positive integer) vertically continuous lines of the CCD for still picture recording or dynamic image processing. Thus it is possible to provide a high pixel density solid-state image sensor output at a high frame rate without use of any high drive frequency.

Electronic imaging system

Disclosed herein is an optical apparatus including: a variable configuration mirror unit having a reflecting surface for reflecting incident light and capable of causing change in the configuration of the reflecting surface upon turning on electricity; and a lens for bringing the incident light into an internal part, a mirror holding section for holding the variable configuration mirror unit being formed on the lens.

Optical apparatus and imaging apparatus using the same

An imaging apparatus includes an interline type CCD image sensor having 1,000,000 or more pixels, which has a Bayer configuration color filter suitable for reading all pixel signals in a line-sequential scanning manner. The imaging apparatus drives the CCD image sensor in a high speed mode usually, and in a high quality image mode only for a trigger depression. In the high speed mode, the CCD image sensor outputs pixel signals for one line at intervals of three lines in the vertical direction. During the high speed mode operation of the CCD image sensor, images are displayed on a liquid crystal display portion at a frame rate of 60 frames/second, the images being recognized by the human eyes as a dynamic image, i.e., a motion picture.

Image pickup apparatus capable of performing both a still image process and a dynamic image process

An image pickup apparatus capable of compensating fault pixels at high accuracy with considering the image configuration in a region surrounding the fault pixels, constructed as including: a CCD image pickup device having two-dimensionally arrayed pixels; a fault pixel information storage means for storing the position of fault pixels of the image pickup device and, if the fault pixels are two-dimensionally consecutive, a pattern of their order; and a pixel defect compensation processing section for detecting an image configuration of a region surrounding a fault pixel location in image pickup signal from pixel information in the surrounding of the fault pixels, selecting based on the detected image configuration pixels by which the fault pixel should be interpolated, and compensating the fault pixels based on interpolation by the selected pixels.

Image pickup apparatus

In an automatic exposure control apparatus, image-capturing is performed at a double exposure time TI (I&equals;1, 2, . . . ) and a single exposure time; a CCD output therein produced is applied with a CCD drive signal to perform an integrating operation for a signal in an AE area by using an integration circuit, and then outputs integration values 2EI&plus;SI and EI&prime;&plus;SI&prime; to an exposure operation/control circuit; and the exposure operation/control circuit then performs an AE operation to receive 2EI&plus;SI&minus;(EI&prime;&plus;SI&prime;)&ap;EI and compares the value to a target value for determining exposure conditions, and upon receipt of a shutter trigger, it uses an AE operation value containing almost no smear component to determine an appropriate exposure condition even in actual image-recording. According to the apparatus herein stated, exposure errors resulting from smears can be prevented.

Automatic exposure control apparatus

A system for automatically erasing a pair of tracks whenever a designated track to be erased belongs to a pair of tracks representing a frame picture. In the system, detecting means detects ID codes indicating field/frame recording mode of a recorded track and feeds a detected signal to a controller, then the controller takes an appropriate action to erase the pair of frame recorded tracks by timely activating head accessing means and an erasing signal generator based on the ID codes, whenever the tracks correspond to a frame picture.
