Description

图像摄取装置、图像摄取装置的控制方法技术领域本发明涉及能进行测光用的预发光等发光的图像摄取装置和图像摄取装置的控制方法。 The method of controlling an image pickup apparatus and an image pickup apparatus TECHNICAL FIELD image pickup means image pickup apparatus according to pre present invention relates to light emission photometric light emission. 更具体地说,涉及适合于使用如CMOS传感器那样的固体摄像器件的图像摄取装置和固体摄像器件的控制方法,该固体摄像器件中,二维地配置有多个光电转换元件,并能够按一行或数行单位错开曝光期间地进行驱动。 And more particularly, relates to a control method suitable for use as a solid imaging device such as a CMOS sensor of the image pickup apparatus and a solid imaging device, the solid-state imaging device, a plurality of two-dimensionally arranged photoelectric conversion elements, and can press line the number of rows or staggered units exposed during driving. 背景技术近年来,高密度地集成了光电转换元件的固体摄像器件被应用于摄像机和数字照相机等,能够在记录介质上记录多张图像数据,或打印输出图像数据,或进行显示器显示。 BACKGROUND ART Recently, high density integration of the solid state imaging device is applied to a photoelectric conversion element, video cameras and digital cameras, a plurality of image data can be recorded on the recording medium, or print the output image data, or monitor. 在这种摄像机、数字照相机等中采用了自动曝光(AE: Automatic Exposure)功能,在日光时,测量摄像面的光量,以所求出的最佳曝光条件进行曝光。 In such a video camera, a digital camera or the like using the automatic exposure (AE: Automatic Exposure) function, in daylight, the measurement light quantity of the imaging plane, the obtained optimum exposure conditions for exposure. 而且,具有闪光灯、电子闪光灯(strobo)等辅助发光装置,在光量较少的夜间或者室内进行摄影时,使上述辅助发光装置闪光进行摄影(闪光摄影)。 Furthermore, with the flash, electronic flash (Strobo) auxiliary light emitting device, the light is small when photographing at night or the amount of room, so that the flash photographing auxiliary light emitting means (flash photography). 在闪光发光时瞬时使用AE功能进行曝光控制,实际上是存在困难的,因此, 一般都是进行测光用的预发光,测量此时的光量,在闪光发光前结束自动曝光控制,然后再进行正式摄影。 When using the flash light emitting instantaneous AE exposure control function it is actually difficult, and therefore, are generally used for pre-light emission photometry, the measurement light amount at the end before the automatic exposure control the flash light emitting, and then official photography. 通常,在固体摄像器件的积累时间外,即使进行预发光也无法准确地测量闪光光量,所以与闪光发光定时同步地进行预发光,进行积累动作。 Typically, the solid state imaging device outside the accumulation time, even if the pre-light emission can not accurately measure the amount of flash light, the flash light emitting timing in synchronism with the pre-light emission, accumulate operation. 近年来,为了在摄像机、数字照相机等中实现高分辨率,致力于使用了微细化工艺的光电转换元件的单元(cell)尺寸的缩小。 Reduction (cell) cell size in recent years, in order to achieve high resolution video camera, a digital camera or the like, using a fine working process of the photoelectric conversion element. 另一方面,由于随着单元尺寸的缩小,造成每一单元的光电转换信号输出下降等,所以能够对光电转换信号进行放大输出的放大型固体摄像器件受到关注。 On the other hand, since as the size of the reduction unit, resulting in decrease of the photoelectric conversion signal output of each cell, and the like, it is possible to perform amplification type solid state imaging device for amplifying the output signal of the photoelectric conversion attention. 关于这样的放大型固体摄像器件,有BASIS、 MOS型、SIT、 AMI、 CMD等XY地址型传感器的二维固体摄像器件。 With respect to such amplification type solid state imaging device, the two-dimensional solid state imaging device BASIS, MOS type, SIT, AMI, CMD, etc. XY address type sensor. 此外,作为其他二维固体摄像器件,基于在高密度化和高S/N方面的优异表现,CCD ( Charge Coupled Device )传感器被广泛使用。 Further, as another two-dimensional solid-state imaging device, based on a high density and high S / N is excellent in terms of performance, CCD (Charge Coupled Device) sensors are widely used. 在具有二维固体摄像器件的数字照相机等中,在拍摄图像时适当地调整该摄像的曝光条件,设定与固体摄像器件的灵敏度相应的曝光时间。 In the digital camera having a two-dimensional solid-state imaging device, appropriately adjusted exposure condition at the time of imaging of the captured image, the sensitivity of the solid imaging device is set corresponding to the exposure time. 在设定该曝光时间时,测量照射到被二维配置的光电转换元件的一部分上的光量,变更光圏等摄影参数,直到测出的光量的值变为某一目标值为止,找到最佳值。 When the set exposure time, measuring the amount of light irradiated to the portion of the photoelectric conversion elements are two-dimensionally arranged, rings of light and so changing the imaging parameter, the value until the measured quantity of light becomes a target value so far, to find the best value. 该动作即为AE( Automatic Exposure )。 The action is the AE (Automatic Exposure). 在使用了CCD传感器的数字照相机中进行AE时,读出全部像素数据存储到存储介质中,从中抽取出预定的块(block)区域,临时累积后,与适当的预定膝光水平进行比较。 When the AE sensor using a CCD digital camera, reading all the pixel data stored in the storage medium and extract a predetermined block (block) area, the temporary accumulation of the knee with an appropriate predetermined light level is compared. 然后,对于变更快门速度、 光圏等摄影参数而读出的像素数据,再次抽取块区域,与预定曝光水平进行比较。 Then, the pixel data change the shutter speed, rings of other imaging parameters read out again block area extracted, is compared with a predetermined exposure level. 通过这样多次反复进行,将块区域的曝光水平变成预定曝光水平时的条件确定为最佳曝光条件。 By repeated several times, the exposure level block region becomes a predetermined condition when the exposure level is determined as the optimum exposure condition. 参照图17A〜图17C,说明由使用了CCD传感器的固体摄像器件进行的AE动作。 Referring to FIG 17A~ FIG. 17C, an operation performed by the AE be described using the solid state imaging device CCD sensor. 传感器的读取方式无论是行间(interline)传送方式还是帧传送方式,从CCD传感器1601按时间序列读出的图像信号都由A/D转换器1602转换成数字图像信号,向帧存储器1603中写入1 帧量。 Whether it is the sensor reading method interline (Interline) mode or transmission mode frame transfer, image signals read out in time series from the CCD sensor 1601 by the A / D converter 1602 into a digital image signal, the frame memory 1603 writing one frame. 在进^亍基于中央重点测光的AE时,特别:地,只读出中心部的块区域,将该块区域的图像信号电平用积分器1604积分,求出该块区域的全部积分值。 When the right foot into the AE ^ based on center-weighted metering, in particular: the read-only portion of the center block area, the image signal level of the block region by integrating the integrator 1604, obtains the integrated value of the block region . 用判定电路1605比较该块区域的全部积分值和预先确定的预定曝光水平,如果该比较结果存在差异,就输出到曝光条件设定电^各1606。 Comparison of the entire region of the block integration value and a predetermined exposure level determined in advance by the decision circuit 1605, there is a difference if the comparison result, is output to the exposure condition setting each electrically ^ 1606. 曝光条件设定电路1606从对CCD传感器1601的曝光时间'快门速度、光圏值、CCD传感器1601的积累时间等曝光条件中,变更例如快门速度等。 Exposure condition setting circuit 1606 from the exposure time of the CCD sensor 1601 'of the shutter speed, the value of rings of light, the accumulation time of the CCD sensor 1601 exposure conditions, for example, changing the shutter speed. 以与曝光条件设定电路1606中的设定对应的曝光条件,再次检测由CCD传感器1601取得的图像数据中的块区域的曝光积分值,由判定电路1605进行比较、判定,反复进行这些操作直到差变为小于等于预定值为止,从而求出最佳的曝光条件。 An exposure condition setting circuit 1606 is set corresponding to the exposure conditions, the exposure detection area of ​​the integral value of the block of image data acquired by the CCD sensor 1601 again, compared by the decision circuit 1605, determination, repeating these operations until It equals the difference becomes smaller than the predetermined value, thereby obtaining the optimum exposure conditions. 将该AE动作表示为图17B的时序图。 The AE is a timing diagram showing the operation of FIG. 17B. 在图17B中,(1 )中以低电平期间表示曝光时间(电荷积累时间)。 In FIG. 17B, (1) indicated with a low level during the exposure time (charge accumulation time). 在AE评价时的(2) 中,在电荷积累和A/D转换后,从帧存储器1603读取块区域,以高电平表示积分处理的期间。 (2), after the charge accumulation, and A / D conversion, the read block area from the frame memory 1603, indicates a high level during the integration process when evaluated in AE. 另外,在各AE评价时的AE值(3)中, 用虚线表示的是预定的AE值。 Further, when each of the AE AE evaluation value of (3), is indicated by broken lines AE predetermined value. 如果用曲线图(graph)来表示,则成为图17C,在第3次的曝光检测值中,AE值过高,通过将第4次的AE值时的曝光条件作为AE用的条件,能够执行最佳的AE。 If represented by a graph (Graph), becomes FIG. 17C, the exposure value detected in the third, AE value is too high, the exposure conditions by an AE fourth value as a condition with AE can be performed best of AE. 近年来,基于廉价、不需要复杂的定时信号发生器、且能以单一电源进行动作、消耗功率也较少等理由,将CMOS传感器使用于二维固体摄像器件的情况逐渐增多。 In recent years, based on low cost, no need for complex timing signal generator, and can be carried out in a single operation power supply, power consumption is less other reasons, in the case of a CMOS sensor using the two-dimensional solid-state image pickup device is gradually increased. 但是,COMS传感器以行单位读出信号,所以每行积累光电荷的开始时间是错开的。 However, the COMS sensor readout signal in units of lines, so that each line begins photocharge accumulated time is offset. 因此,有时用于AE的光量积累的定时按每行错开,用于AE评价的块区域的积累时间和预发光时间错开。 Thus, sometimes the amount of light accumulated for AE shifted timings for each row, the accumulation time for the block AE evaluation area and pre-emission time offset. 即,有时被包含在用于AE评价的块区域中的行中,出现在预发光中不进行积累的行。 That is, the line is sometimes contained in the AE evaluation area for the block in the row do not accumulate in the pre-light emission occurs. 作为这一问题的对策,在例如日本特开2000-196951号公报中, 公开了如下内容:进行控制,使得在块区域中的各读取行在时间上重叠的期间内进行预发光,从而预发光被照射到整个块区域。 As a countermeasure to this problem, for example, in Laid-Open Patent Publication No. 2000-196951 Japanese discloses the following: controlled such that the overlapping period of time in each read block row pre-light emission region, thereby pre emitting region is irradiated to the entire block. 但是,在进行日间同步(synchro)摄影等快门速度为高速的情况下,有时块区域中的各读取行在时间上重叠的期间并不存在。 However, during the daytime synchronization (SYNCHRO) photography, the shutter speed at a high speed, and sometimes there is no overlapping period of time on each line read in the block area. 在这样的情况下,如果在任意的定时进行预发光,则由外光和闪光灯的反射光构成的摄影光的光电荷,与仅由外光构成的摄影光的光电荷混在一起被积累在CMOS传感器中。 In this case, if the pre-light emission at an arbitrary timing, the light of the light reflected by the photographic charges the outer configuration of the light flash light, photographic light photocharge is constituted only by the outer light is accumulated in the CMOS mixed sensor. 其结果,存在无法检测出准确的光量的问题。 As a result, there is a problem can not detect the exact amount of light.

FIG. 5 is a detailed flowchart of step S123 of FIG. 3 in photographic processing. 系统控制部50如在图4中说明的那样,按照存储在系统控制部50的内部存储器或者存储器52中的测光数据,控制曝光控制部40, 使具有光圏功能的快门12按照光围值开放(步骤S301)。 50 described as part of the control system in FIG. 4, in accordance with the photometry data stored in the internal memory or the memory 52 in the system control unit 50 controls the exposure control unit 40, the shutter 12 having a light rings of light confining function in accordance with the value of open (step S301). 然后,开始固体摄像元件14的曝光(步骤S302 )。 Then, the start of the solid-state imaging device 14 exposed (step S302). 接着,根据闪光灯标志判断是否需要闪光灯(步骤S303 ),如果需要,则使闪光灯48发光(步骤S304 )。 Next, the strobe flash flag whether it is necessary (step S303), if necessary, the flash lamp 48 emits light (step S304). 如果不需要闪光灯,则不使闪光灯48发光地进入步骤S306。 If no flash, no flash lamp 48 emitting into step S306. 系统控制部50按照测光数据等待固体摄像元件14的曝光结束(步骤S305 )。 The system control unit 50 waits for the solid imaging device in accordance with the photometric data exposure ends (step S305) 14 a. 曝光时间结束后,关闭快门12(步骤S306),从固体摄像元件14读出电荷信号。 After the exposure time, closes the shutter 12 (step S306), the charge signals read from the solid imaging element 14. 然后,经由A/D转换器16、图像处理部20、存储器控制部22,或者从A/D转换器16直接经由存储器控制部22,将图像数据写入存储器30 (步骤S307)。 Then, via the A / D converter 16, image processing unit 20, the memory control unit 22, 22 or 16 directly, the image data written in the memory 30 via the memory control unit from the A / D converter (step S307). 接着,根据所设定的摄影模式,顺次进行完色处理后(步骤S310), 将完成了处理的图像数据写入存储器30中,结束摄影处理程序。 Next, according to the set photographing mode, sequentially after completion color (step S310) process, the completion of processing the image data written in the memory 30, the photography processing routine ends. 图6是表示图3的步骤S124中的记录处理的详细流程图。 FIG 6 is a detailed flowchart showing the recording process of step S124 in FIG. 3. 系统控制部50使用存储器控制部22、根据需要也使用图像处理部20,读出被写入到存储器30中的图像数据,由压缩解压缩部32进行与所设定的模式相应的图像压缩处理(步骤S402)。 The system control unit 50 using the memory control unit 22, according to need using the image processing unit 20, the read data is written into the image memory 30 by the compression portion 32 is decompressed corresponding to the set mode and image compression processing (step S402). 然后,将压缩图像数据经由接口90或94、连接器92或96,写入到存储卡、CF ( compact flash:注册商标)卡等记录介质200或201 (步骤S403 )中,结束记录处理程序。 Subsequently, the compressed image data via the interface 90 or 94, connector 92, or 96, is written to the memory card, CF (compact flash: registered trademark) card or the like recording medium 200 or 201 (step S403), the recording processing routine ends. 在以上说明的图像摄取装置中,在闪光灯为ON时,如图7中也图示出的那样,在快门开关SW1变成ON时(步骤S119),进行测距-测光.测色处理(步骤S120)。 In the image pickup apparatus explained above, when the flash is ON, also in FIG. 7 as illustrated, is turned ON when the shutter switch SW1 (step S119), distance measurement - photometric colorimetric process ( step S120). 之后,如果快门开关SW2变成了ON(步骤S121 ),则将从固体摄像元件14读出信号的信号读取方式, 从EVF读取模式切换成预发光读取模式(步骤S128)。 Thereafter, if the shutter switch SW2 becomes ON (step S121), then the read mode signal 14 from the signal readout solid-state imaging device, the switching from the read mode to the EVF mode pre-flash reading (step S128). 然后,作为预发光'曝光处理,进行预发光和预曝光、信号读取(步骤S129)。 Then, as the pre-light emission 'exposure, pre-light emission and the pre-exposure signal is read (step S129). 即,在预发光时,转移到与EVF读取模式、正式曝光读取模式不同的预发光读取模式。 That is, when pre-emission, is transferred to the EVF read mode, a read mode different formal exposure reading mode pre-light emission. 如此,通过在快门开关SW2变成ON后即刻进行预发.曝光处理,缩短正式曝光开始时间与预曝光开始时间的时间, 因而能够实现高精度的闪光灯调光。 Thus, by the shutter switch SW2 is turned ON in advance immediately. Exposure processing, the exposure start time is shortened and the official start time of the pre-exposure time, it is possible to achieve high-precision flash light adjustment. 在这种情况下,在快门开关SW2变成ON时,图像显示装置28 的显示(EVF输出)更新中止,按预发光读取模式读出的信号不进行直通显示。 In this case, when the shutter switch SW2 is turned into ON, the image display (EVF output) update the suspension device 28, the signal read by the pre-light emission is not performed through reading mode display. 图8是用作固体摄像元件14的COMS传感器的电路图。 FIG 8 is a circuit diagram of the sensor as a solid imaging element 14 COMS. 在该图中,B11~B44是具有光电二极管等光电转换元件、读出光电转换元件的积累电荷并进行放大的放大型MOS晶体管、激活放大型MOS晶体管的选择MOS晶体管等的像素。 In the figure, B11 ~ B44 having a photoelectric conversion element such as a photodiode, and charge is accumulated

像素被配置成矩阵状(图示例中为4x4的像素)。 Pixels are arranged in a matrix (in the illustrated example is 4x4 pixels). 在EVF读取模式中,例如设定为对水平方向上2像素、垂直方向上2像素进行相加平均。 Reading in the EVF mode, for example, set for the pixels on the 2 2 pixels in the vertical direction in the horizontal direction, an arithmetic mean. 即,输出从垂直移位存储器801按每一水平行读出的VSEL1,由VSEL1的控制脉冲选择的各像素的光输出, 被读出到各垂直输出线VSIG1 ~4,存储到加法电路802中。 That is, the output from the memory 801 by the vertical shift each horizontal row VSEL1 read out, the light output of each pixel of the selected VSEL1 control pulse, and is read out to the respective vertical output lines VSIG1 ~ 4, stored in the addition circuit 802 . 图9是表示加法电路802的电路结构的图,表示水平方向的2像素Bll、 B12和垂直方向的2像素B12、 B22的光输出进行相加运算的情况。 FIG 9 is a diagram showing a circuit configuration of the adder circuit 802, represents a case where 2 horizontal pixels Bll, B12, and B12 2 pixels in the vertical direction, B22 light output of the addition operation. 如该图所示那样,像素Bll、 B12的信号成分,从与各像素连接的垂直输出线经由传送开关901、 902,被存储到存储电容903、 904中。 As shown in the figure as pixel Bll, B12 signal component from vertical output line connected to each pixel via the transfer switches 901, 902, are stored into the capacitor 903, 904.在下一个定时输出图8的VSEL2,像素B21、 B22的信号成分经由传送开关905、 906 ^皮存储到存储电容907、 908中。然后,根据来自水平移位寄存器803的控制信号,传送开关909、 910、 911、 912变成0N。由此,在水平输出线913中,水平方向的像素Bll和B12的信号成分、以及垂直方向的像素B21和B22的信号成分进行加法计算,完成了水平、垂直2像素的加法计算。此处,对使用了CMOS传感器等滚动式(rolling)电子快门方式时的定时的错开, 一边参照图10A的COMS传感器的读取方式和图10B的预发光(EF)的说明图, 一边进行说明。图IOA表示例如基于CM 0 S传感器的EF评价块区域的预发光的光电荷的积累定时状态。要想积累CMOS所接收的光电荷时,是按1行单位读出信号的,所以各行n、 n+l、 n + 2..... m的积累开始是分别错开的。而且,对于EF动作,在某时间内使闪光灯进行预发光时的光强度,以时间为横轴,如图IOB所示那样变化,CMOS传感器收到该光量变化,对从全部区域内抽取出的一部分块区域进行评价。此时,EF 评价块区域的行n~ m全部都必须在预发光期间内进行电荷的积累。即,如果不是所有EF评价块区域对预发光的光进行受光,就无法准确检测出闪光,将导致精度下降。在图IOA和图IOB的例子中, EF评价块区域全部对预发光的光进行受光。接着,对于在什么样的情况下,预发光无法投射到EF评价块区域的一部分的情况,举例进行说明。 〔正常闪光摄影时(快门速度1/60sec)〕图11表示EF评价块区域的积累时间的定时。当前,快门速度为1/60sec,因此积累时间变成16.7ms。而且,在々U殳读出1行所需要的时间为24jis, EVF的垂直方向的行数为180条时,每1画面的读取时间为24psxl80 = 4.3ms。由图11可知,EF块区域的所有行的积累时间的重叠期间为12.4ms。如果假设预发光时间为20ps,则通过在该重叠期间进行预发光,就可以向EF评价块区域的所有行投射预发光。 〔日间同步摄影时(快门速度1/250sec )〕图12表示EF评价块区域的积累时间的定时。当前,快门速度为1/250sec,因此积累时间变成4ms。而且,假定读出l行所需要的时间、垂直方向行数与正常闪光摄影时相同。在这种情况下,由图12 可知,EF评价块区域的所有行不存在时间上的重叠期间,因此,无论以什么样的定时进行预发光,都无法将预发光投射到EF评价块区i或的一部分行。这样,在日间同步摄影时等快门速度高的情况下,与读出l行所需要的时间相比,积累时间变短。因此,在EF评价块区域的行中, 出现未被预发光的行。根据上述结果,在同步快门速度、从EF评价块区域读出信号的读取时间、预发光时间满足下式(1)时,才能将预发光投射到所有EF评价块区域。同步快门速度S读取时间+预发光时间......式(1)因此,在预发光时通过改变用于缩短来自下述这样的固体摄像元件的预定区域(在本实施方式中为4x4像素)的信号的读取期间的参数,使之以预发光读取模式进行动作。 (1 )读取水平像素数(2) 驱动频率(3) 水平消隐时间(4) 读取垂直像素数通过改变(1) 、 (2) 、 (3)的值,能够改变时序图的平行四边形的倾斜。将该情况表示在图13中。而且,在改变了(4)的值时, 读出行数发生变化,因此,时序图如图14那样变化。通过改变这4 个值中的至少l个值,能够在由快门速度决定的积累时间内使最初读出的行和最后读出的行在时间上重叠。因此,能够成为预发光投射到所有EF评价块区域这样的预发光读取模式。 (第2实施方式)在上述第1实施方式中,在预发光时总是转移到预发光读取模式。而且在预发光读取模式中,如上述那样通过将(1 )读取水平像素数、 (2)驱动频率、(3)水平消隐时间、(4)读取垂直像素数设定为适当的值,使预发光投射到所有EF评价块区域。然而,为了应对高速快门,趋向于削减读取水平像素数、读取垂直像素数,由于间隔过大有可能会造成闪光灯调光精度下降。而且对于驱动频率,是趋向于增加的,所以也考虑到可能消耗功率也随之增大。而且,对于水平消隐时间,是趋向于减少的,所以考虑到由于开关速度的高速化,可能会带来传感器性能的劣化。在本实施方式中,判定预发光是否能投射到所有EF评价块区域,只有在该判定为否的情况下才转移到预发光读取模式。图15是对应于上述第1实施方式的图3的流程图,对于与图3相同的处理动作贝武予相同的标号,在此仅对不同点进行说明。如果按下了快门开关SW2 (步骤S121 ),则系统控制部50判断是否需要闪光灯(步骤S127)。如果需要,则首先判断快门速度是否大于等于阈值(步骤S130)。该阈值等于上述式(1)所示的"读取时间+预发光时间"。然后,如果快门速度不是大于等于阈值,则预发光就无法投射到所有EF评价块区域,因此切换为预发光读取才莫式(步骤S128)。但是,如果快门速度大于等于阈值,则保持EVF 读取模式(步骤S131),就此进行预发光'曝光处理(步骤S129)。 (第3实施方式)在第1实施方式中,是在预发光模式中调整(l)读取水平像素数、 (2)驱动频率、(3)水平消隐时间、(4)读取垂直像素数,使得即便在高速快门时也能让预发光投射到所有EF评价块区域的。然而,由于对驱动频率是趋向于增加地进行调整的,所以考虑到可能消耗功率会增大。在本实施方式中,是根据快门速度变更驱动频率的。现在,采用驱动频率可选择40MHz、 20MHz、 lOMHz这3种的传感器。另外,设数字照相机的同步快门速度为1/500s(2ms),进而设预发光时间为1/2000s (0.5ms), 40MHz驱动时的读取时间为1.5ms。在这种情况下,同步快门速度变成大于等于(40MHz驱动时的读取时间+预发光时间),预发光投射到所有EF评价块区域。进而,假设20MHz驱动时的读取时间为2ms, 10MHz驱动时的读取时间为2,5ms。在这种情况下,在20MHz驱动时,满足上述式(1 ) 的最小的快门速度成为读取时间2ms +预发光时间0.5ms = 2.5ms U/400s)。即,大于等于2.5ms的快门速度也可以将驱动频率设定为20MHz。同样地,在10MHz驱动时,满足上述式(1 )的最小的快门速度为读取时间2.5ms+预发光时间0.5ms = 3.0ms ( l/333s)。即,大于等于3.0ms的快门速度也可以将驱动频率设定为lOMHz。即,总结快门速度Tv和驱动频率,如以下这样。 (情况1 ) 2ms^Tv〈2.5ms以驱动频率40MHz满足上述式(1 )。 (情况2 ) 2.5ms£Tv<3ms以驱动频率20MHz满足上述式(1 )。 (情况3 ) 3ms^Tv以驱动频率10MHz满足上述式(1 )。将上述关系总结于图16。基于此,不需要始终以40MHz的频率驱动,可以根据快门速度而放慢驱动频率,结果是能够降低功率消耗。 (其他实施方式)另外,显然本发明的目的还可以这样来实现:将记录了实现上迷实施方式的功能的软件的程序代码的存储介质,提供给系统或者装置,该系统或者装置的计算机(或者CPU、 MPU)读出并执行存储在存储介质中的程序代码。在这种情况下,从存储介质中读出的程序代码本身就实现上述实施方式的功能,存储代码本身以及存储了该程序代码的存储介质就构成本发明。作为用于提供程序代码的存储介质,可以使用例如软盘、硬盘、 光盘、光磁盘、CD-ROM、 CD-R、磁带、非易失性存储卡、ROM等。而且,不仅通过计算机执行读出的程序代码,能够实现上述实施方式的功能,根据该程序代码的指示,在计算机上运行的OS(基本系统或操作系统)等进行实际处理的一部分或全部,通过该处理实现上述实施方式的功能的情况显然也包含在本发明的范围内。进而,从存储介质读出的程序代码,在被写入到插在计算机中的功能扩展卡或连接在计算机上的功能扩展单元所具备的存储器中后, 根据该程序代码的指示,该功能扩展卡或功能扩展单元所具有的CPU 等进行实际处理的一部分或全部,通过该处理来实现上述实施方式的功能的情况显然也包含在本发明的范围内。以上,通过优选实施方式对本发明进行了详细的说明,在不脱离本发明的精神和范围的前提下,本发明可以进行各种不同的变更,并且应该理解为,本发明不受上述特定的实施方式的限定,其范围由所附的权利要求限定。
