After carrying out AF action, then, light-metering action (S35) is carried out.Here be obtain subject brightness according to the picture signal obtained by image sensor 9.
After carrying out light-metering action, then, image procossing (S37) is carried out.Here being the picture signal according to being obtained by image sensor 9, being converted to the picture signal of live view display by image processing part 15.Usually, the pixel count of image sensor 9 is more than the pixel count needed for live view display, thus as the image procossing in this step, carries out the process reducing pixel count etc.
After carrying out image procossing, then, judge whether external light sensor detects more than 100000lx (lux) (S39).Here be carry out light-metering by external light sensor 35, judge its light value whether as more than 100000lx.And, as described later, whether decision content 100000lx is set to the decision content with biased gamma curve by the gamma curve of the liquid crystal display part 33 of display for switching, and thus according to the display characteristic of liquid crystal display part 33, suitably decides as design load.
When the exterior light brightness that the result of determination of step S39 is external light sensor 35 detection is less than 100000lx, utilize usual set point gamma curve on liquid crystal panel, carry out image display (S97).In this step, carry out common gamma correction, that is, as shown in Figure 5, relative to the gamma curve 61 (in figure dotted line) of input gray level monotone increasing, gamma correction is carried out to picture signal according to output gray level, liquid crystal display part 33 carries out the image display of live view.
On the other hand, when the exterior light brightness that the result of determination of step S39 is external light sensor 35 detection is more than 100000lx, gamma curve is set as have biased (S91), utilizes the gamma curve of setting on liquid crystal panel, carry out image display (S93).Here, as gamma curve, be arrange as shown in Figure 5 there is biased gamma curve 62 (in figure solid line), carry out gamma correction according to this gamma curve 62 pairs of picture signals, liquid crystal display part 33 carries out the image display of live view.
Further, this has biased gamma curve 62 relative to not having biased gamma curve 61 and improves dark portion side (in figure on the left of transverse axis).In the example as shown in fig. 5, gamma curve 62 is such curves: add bias to gamma curve 61 simply, saturated in high input value side.But be not limited to this, such as also can determine as follows there is biased gamma curve: add bias in dark portion side, reduce this bias gradually in high input value side and be added with gamma curve or increase bias gradually and be added with gamma curve, reach capacity in high input value side state.
After liquid crystal panel (liquid crystal display part 33) carries out image display, then, the brightness (S95) of the backlight of liquid crystal panel is weakened.LCD Controlling portion 31 reduces the brightness of the backlight of liquid crystal display part 33, realizes the reduction of power consumption.Its reason is, has biased gamma curve and has carried out gamma correction owing to using and to make in shot object image comparatively dark-part become bright, even if thus reduce back light source brightness also can observe confirmation fully.
Like this, in the flow process of live view action, when exterior light too bright and be difficult to the picture of direct viewing liquid crystal display part 33 time, gamma curve is changed to and has biased, carry out gamma correction.Therefore, part darker in shot object image can entirety brighten, even if therefore too bright around, also can observe fully.In this case, in shot object image, bright part is in saturation condition and is showed by white originally, owing to becoming clear, therefore there will not be discomfort around.
Carry out the weakening or show image on liquid crystal panel in S97 of backlight in step S95 after, turn back to original flow process.
Then, the reproducing movement of the flow chart description of step S23 shown in Fig. 4 is used.After entering the flow process of reproducing movement, first, read and select image, carry out image procossing (S101).In reproducing movement, using up-to-date document image etc. as selection image, from recording medium 25, read the picture signal selecting image, carry out decompression in compressed and decompressed portion 23 after, in image processing part 15, carry out image procossing.
After carrying out image reading and image procossing, then, identical with step S39, external light sensor determines whether the exterior light brightness (S103) that there is more than 100000lx.Judge that whether the exterior light brightness when reproducing near liquid crystal display part 33 is excessively bright.
When the result of determination of step S103 be exterior light brightness is not more than 100000lx, identical with step S37, utilize usual set point gamma curve on liquid crystal panel, carry out image display (S167).Here be, according to the gamma curve 61 shown in Fig. 5, gamma correction is carried out to the picture signal read from recording medium 25, liquid crystal display part 33 carries out the display of reproduced image.
On the other hand, when the result of determination of step S103 be exterior light brightness is more than 100000lx, gamma curve is set as have biased (S161), utilizes the gamma curve of setting on liquid crystal panel, carry out image display (S163).Because exterior light brightness is at more than 100000lx, thus the vicinity of liquid crystal display part 33 is too bright, is difficult to the picture directly observing liquid crystal display part 33.So, in the same manner as the situation that live view shows, gamma curve is set to and has biased, picture is easily observed.That is, according to there is biased gamma curve 62 shown in Fig. 5, the gamma correction of picture signal is carried out.Comparatively dark-part in shot object image can entirety brighten, even if therefore the surrounding of liquid crystal display part 33 is too bright, also can observe fully.
After liquid crystal panel (liquid crystal display part 33) carries out reproduced image display, then, the brightness (S165) of the backlight of liquid crystal panel is weakened in the same manner as step S95.LCD Controlling portion 31 reduces the brightness of the backlight of liquid crystal display part 33, realizes the reduction of power consumption.
Carried out in step S165 backlight brightness deterioration or carried out in step S167 image display after, then, determine whether the switching (S171) of the display image indicating rear face liquid crystal.In the present embodiment, the switching of reproduced image is undertaken by the operation of cross key etc., thus in this step, by determining whether that operating cross key etc. judges.
When the result of determination of step S171 is the switching instruction having carried out showing image, return step S101, according to switching instruction, carry out the reading selecting image.On the other hand, when result of determination is the switching instruction not carrying out showing image, then, the end operation (S173) having carried out reproduction mode is determined whether.In the present embodiment, the end of reproduction mode by again operating reproduction button to carry out, therefore in this step, according to whether operating reproduction button to judge.
When the result of determination of step S173 is the end operation not carrying out reproduction mode, returns step S101, proceed reproduction mode.On the other hand, when the end operation carrying out reproduction mode, after carrying out the ending process of reproduction mode, turn back to original flow process.
Like this, in the flow process of reproducing movement, identical with the situation of live view action, when reproducing exterior light too bright and be difficult to the picture directly observing liquid crystal display part 33, gamma curve is changed to and has biased, carry out gamma correction.Therefore, the comparatively dark-part in shot object image can entirety brighten, even if therefore too bright around, also can observe fully.In this case, in shot object image, bright part is in saturation condition and is showed by white originally, owing to becoming clear, therefore there will not be discomfort around.
As mentioned above, in the 1st execution mode of the present invention, generate display image signals or the 2nd display picture signal, when outside brightness is greater than the value predetermined, show the image based on the 2nd display picture signal, when outside brightness is less than the value predetermined, show the image based on display picture signal, this display image signals generates according to the picture signal from image pickup part or recording medium, 2nd display picture signal uses to be had biased gamma curve and carries out gamma correction to this display picture signal and obtain.Therefore, even if when too becoming clear around, the observability of image displaying part also can be improved.In addition, can also according to the light quantity detected by external light sensor to change the amount of bias of gamma curve.The light quantity detected is larger, then more increase amount of bias, can improve observability accordingly thus with the change of lightness around.
Then, use Fig. 6 to Fig. 8, second embodiment of the present invention is described.In the 1st execution mode, when outside brightness is high brightness, gamma curve is changed to have biased, and in the 2nd execution mode, except the condition that outside brightness is high brightness, also just gamma curve to be changed to when to show image be below regulation lightness have biased.Specifically, obtain the histogram of image, when the pixel that pixel intensity is less than the value predetermined is more, gamma curve is changed to have biased.
The circuit structure of present embodiment is identical with the block diagram shown in Fig. 1 in the 1st execution mode, thus detailed.In addition, the action that camera power source is connected is also identical with the flow chart shown in Fig. 2, thus detailed.But the flow chart of live view action and reproducing movement is different from the 1st execution mode, is therefore described centered by difference.
In the flow process of the live view action shown in Fig. 6, the process of each step of step S31 ~ S39, step S91 ~ S97 is identical with the flow process of the live view action of the 1st execution mode shown in Fig. 3, therefore identical number of steps is marked to the step of carrying out same treatment, detailed.
After entering the flow process of live view action, carry out shooting action (S31), AF action (S33), light-metering action (S35), image procossing (S37), when the result of determination of step S39 be external light sensor more than 100000lx detected time, then, the histogram (S41) of liquid crystal panel display image is calculated.Here, for the display picture signal generated according to the picture signal obtained by image sensor 9, according to the data of each pixel, histogram is obtained.As shown in Figure 8, histogram gets location of pixels on transverse axis, and the longitudinal axis is got signal output, the i.e. input gray level of each pixel.Histogram shown in Fig. 8 shows the histogram relevant with 1 row in display picture signal, also can use the histogram relevant with multirow, the histogram relevant with whole display picture signal or the histogram relevant with the display picture signal in a part of region of regulation can also be used.
After calculating histogram, then, according to histogram, judge whether the pixel of gray scale less than 135 exists more than 50% (S43) in image.In the present embodiment, the input gray level (signal output) of each pixel is 8, and thus the value of each pixel is between peak 255 and minimum 0.Here, with 135 in the middle of it for benchmark, judge that whether the ratio of the pixel less than this decision content is as more than 50%.Further, gray scale 135 and 50% is only example, suitably can determine after the characteristic considering liquid crystal display part 33.
Be that the pixel of gray scale less than 135 is when image memory is more than 50% in the result of determination of step S43, identical with the situation of the 1st execution mode, gamma curve is set as have biased (S91), utilize the gamma curve after setting on liquid crystal panel, carry out image display (S93), carry out the brightness deterioration (S95) of the backlight of liquid crystal panel.Owing to being judged to be that in step S39 exterior light brightness is high brightness and is judged to be that in step S43 the pixel darker than regulation brightness exists more than half, thus identical with the 1st execution mode, gamma curve is changed to have biased, gamma correction is carried out to picture signal, even if obtain the picture also easily observed when exterior light is high brightness thus.
On the other hand, when the result of determination of step S39 be exterior light brightness not more than the result of determination of 100000lx or step S43 be the pixel of gray scale less than 135 in image not more than 50%, identical with the 1st execution mode, utilize usual set point gamma curve on liquid crystal panel, carry out image display (S97).In this case, although exterior light is not high brightness or exterior light, to be high brightness from the histogram shot object image of display image less compared with dark-part, also can not be difficult to observe even if thus utilize common gamma curve to carry out gamma correction.
Carried out in step S95 the backlight of liquid crystal panel brightness deterioration or carried out in the step s 97 image display after, turn back to original flow process.
Then, use the flow chart shown in Fig. 7, the reproducing movement of present embodiment is described.In the flow process of the reproducing movement shown in Fig. 7, the process of each step of step S101 ~ S103, step S161 ~ S173 is identical with the flow process of the reproducing movement of the 1st execution mode shown in Fig. 4, therefore identical number of steps is marked to the step of carrying out same treatment, detailed.
After entering the flow process of reproducing movement, read and select image, carry out image procossing (S101), judge whether external light sensor detects more than 100000lx (S103).When the result that this judges detects more than 100000lx as external light sensor, then, the histogram (S111) of liquid crystal panel display image is calculated.Here, for the display picture signal generated according to the picture signal read out from recording medium 25, the data according to each pixel obtain histogram.As shown in Figure 8 above, histogram gets location of pixels on transverse axis, and the signal that the longitudinal axis is got each pixel exports (input gray level).
After calculating histogram, then, identical with step S43 (see Fig. 6), according to histogram, judge whether the pixel of gray scale less than 135 exists more than 50% (S113) in image.In the present embodiment, identical with the situation that live view shows, when reproducing display, the input gray level (signal output) of each pixel is also 8, thus the value of each pixel is between peak 255 and minimum 0, with 135 in the middle of it for benchmark, judge that whether the ratio of the pixel less than this decision content is as more than 50%.Further, when reproducing movement, gray scale 135 and 50% is only example, suitably can determine after the characteristic considering liquid crystal display part 33.
When the pixel that the result of determination of step S113 is gray scale less than 135 does not exist more than 50% in image or the result of determination of step S103 be the brightness of exterior light is not more than 100000lx, identical with step S97, utilize usual set point gamma curve on liquid crystal panel, carry out image display (S167).Here be, according to the gamma curve 61 shown in Fig. 5, gamma correction is carried out to the picture signal read out from recording medium 25, liquid crystal display part 33 carries out the display of reproduced image.
On the other hand, be that the pixel of gray scale less than 135 is when image memory is more than 50% in the result of determination of step S113, gamma curve is set as have biased (S161), the gamma curve set by utilization carries out image display (S163) on liquid crystal panel.Brightness due to exterior light is more than 100000lx and existing compared with dark-part in reproduced image is more than half, therefore, reproduced image is darker, and the vicinity of liquid crystal display part 33 is excessively bright, be difficult to the picture directly observing liquid crystal display part 33, therefore show identical to situation with live view, gamma curve is set to and has biased, picture is easily observed.
After liquid crystal panel carries out the display of reproduced image, then, identical with step S95, weaken the back light source brightness (S165) of liquid crystal panel.LCD Controlling portion 31 reduces the brightness of the backlight of liquid crystal display part 33, realizes the reduction of power consumption.
Carried out in step S165 backlight brightness deterioration or carried out in step S167 image display after, then, determine whether the switching (S171) of the display image carrying out rear face liquid crystal, when result of determination is the switching carrying out showing image, return step S101.On the other hand, when not carrying out the switching showing image, then, determine whether to have carried out reproduction mode end operation (S173).Be, when not carrying out end operation, return step S101 in result of determination, on the other hand, when having carried out end operation, carry out ending process of reproducing movement, having turned back to original flow process.
Like this, in second embodiment of the present invention, the pixel in the histogram of the Luminance Distribution of the picture element signal of formation display image, below regulation brightness exceedes specified quantity, be judged to be that display image is the lightness of below regulation lightness.Therefore, it is possible to judge accurately according to the Luminance Distribution of each pixel, the observability of image displaying part can be improved further when high brightness.Further, can also the quantity of pixel according to the rules below brightness, change the amount of bias of gamma curve.Pixel count below regulation brightness is more, then more increase amount of bias, thus can change with the lightness of image of display and improve observability accordingly.
Then, use Fig. 9 and Figure 10, third embodiment of the present invention is described.In the 2nd execution mode, except outside brightness is this condition of high brightness, also just gamma curve to be changed to when to show image be below regulation lightness have biased.Specifically, obtain the histogram of pixel, when the pixel that pixel intensity is less than the value predetermined is more, gamma curve is changed to have biased.On the other hand, in the 3rd execution mode, except outside brightness is this condition of high brightness, also obtain the histogrammic mean value of image, when this mean value is less than setting, just gamma curve is changed to have biased.
The circuit structure of present embodiment is identical with the block diagram shown in Fig. 1 in the 1st execution mode, thus detailed.In addition, the action that camera power source is connected is also identical with the flow chart shown in Fig. 2, thus detailed.But flow chart and the 1st, the 2nd execution mode of live view action and reproducing movement are different, are therefore described centered by difference.
In the flow process of the live view action shown in Fig. 9, the process of each step of step S31 ~ S39, step S91 ~ S97 is identical with the flow process of the live view action of the 1st execution mode shown in Fig. 3, therefore identical number of steps is marked to the step of carrying out same treatment, detailed.
After entering the flow process of live view action, carry out shooting action (S31), AF action (S33), light-metering action (S35), image procossing (S37), when the result of determination of step S39 be external light sensor more than 100000lx detected time, then, the histogram (S51) that liquid crystal panel shows image is calculated in the same manner as step S41 (see Fig. 6).Here be obtain histogram in the same manner as curve chart shown in Fig. 8.
After calculating histogram, then, according to the mean value (S53) of histogram calculation input gray level.Here, by total additive value of the input gray level (signal output) of all pixels of subject area divided by total pixel number, thus mean value is calculated.Subject area can be a part of region of the regulation such as the whole region of display picture signal or the central portion of picture.
After calculating the mean value of input gray level, then, histogrammic mean value is judged whether as gray scale less than 135 (S55).In the present embodiment, the input gray level (signal output) of each pixel is 8, and thus the value of each pixel is between peak 255 and minimum 0.Here, with 135 in the middle of it for benchmark, judge whether histogrammic mean value is less than this decision content.Further, gray scale 135 is only example, suitably can determine after the characteristic considering liquid crystal display part 33.
When the result of determination of step S55 be histogram mean value is gray scale less than 135, in the same manner as the 1st, the 2nd execution mode, gamma curve is set as have biased (S91), utilize the gamma curve of setting on liquid crystal panel, carry out image display (S93), carry out the brightness deterioration (S95) of the backlight of liquid crystal panel.

Carried out in step S95 the backlight of liquid crystal panel brightness deterioration or carried out in the step s 97 image display after, turn back to original flow process.
Then, use the flow chart shown in Figure 10, the reproducing movement of present embodiment is described.In the flow process of the reproducing movement shown in Figure 10, the process of each step of step S101 ~ S103, step S161 ~ S173 is identical with the flow process of the reproducing movement of the 1st execution mode shown in Fig. 4, therefore identical number of steps is marked to the step of carrying out same treatment, detailed.
After entering the flow process of reproducing movement, read and select image, carry out image procossing (S101), judge whether external light sensor detects more than 100000lx (S103).When the result that this judges detects more than 100000lx as external light sensor, then, the histogram (S121) that liquid crystal panel shows image is calculated in the same manner as step S111 (see Fig. 7).
After calculating histogram, then, identical with step S53 (see Fig. 9), according to histogram, calculate the mean value (S123) of gray scale.After obtaining histogrammic mean value, then, mean value is judged whether as gray scale less than 135 (S125) in the same manner as step S55.
When the result of determination of step S125 be result of determination that histogrammic mean value is greater than gray scale 135 or step S103 be exterior light brightness is not more than 100000lx, same with step S97, utilize usual set point gamma curve on liquid crystal panel, carry out image display (S167).Here be, according to the gamma curve 61 shown in Fig. 5, gamma correction is carried out to the picture signal read from recording medium 25, liquid crystal display part 33 carries out the display of reproduced image.
