4 is a block diagram of an image photographing apparatus according to various embodiments of the present disclosure. Referring to FIG. 4, the image capturing apparatus 400 may include an image sensor 410 and a digital image processor 420.

The image sensor unit 410 may include an image sensor 411, a low driver 412, an analog to digital converter (ADC) 413, and a correlated doubled sampling (CDS) 414. It may include, and may be integrated into one chip.

Readout may be performed or readout may be performed in a column unit in a changed order according to a control signal.

5 is a circuit diagram of each pixel of the CMOS image sensor according to various embodiments of the present disclosure. Referring to FIG. 5, each pixel 500 of the CMOS image sensor 411 includes a photo diode 501, a storage diode 502, and a floating diffusion capacitor. Capacitor, hereinafter referred to as FD) 503, first reset transistor (Reset Transistor 1, hereinafter referred to as RST1) 504, second reset transistor (Reset Transistor 2, hereinafter referred to as RST2) 505, first transfer transistor (Transmit Transistor 1, And a second transmission transistor (Transmit Transistor 2, hereinafter referred to as TX2) 507, a Select Transistor (hereinafter referred to as SEL) 508, and the like.

The photodiode 501 is installed in an exposed state, converts an incident optical signal into an electrical signal, and outputs it to the storage diode 502, and the storage diode 502 is installed in a shielded state and receives and stores the electrical signal. Can be.

The floating diffusion capacitor 503 may remove noise components stored in the storage diode 502. For example, it is possible to easily remove predictable noise components generated by device-specific characteristics such as heat generation. The plurality of transistors 504 to 508 may be selectively turned on / off according to a control signal applied by a global shutter method of the row driver 412.

The storage diode 502 is in a shielded state, but since the gate, which is a connection passage with the photodiode 501, is not in a shielded state, light emitted or reflected by a high-luminance subject such as a light source is introduced into the storage diode 502 through the gate. Light leakage may occur.

When photographing a high-luminance subject such as the light source or the like, since the electrical signal converted by the photodiode 501 suddenly overflows, the light leakage phenomenon may abnormally flow into the storage diode 502.

When a high-luminance subject such as the light source is moved within the photographed image, distortion and blurring of the shape of the high-luminance luminance subject displayed on the display screen may occur, resulting in a noticeable deterioration in the image quality of the photographed image. have.

6 is a diagram illustrating a blooming phenomenon appearing on a display screen according to various embodiments of the present disclosure. Referring to FIG. 6, for example, when the image capturing apparatus 610 of the smartphone 600 photographs a high-luminance subject such as a light source, the shape of the high-luminance subject 630 may be distorted and distorted on the display screen 620 of the smartphone 600. Smearing may occur.

The digital image processor 421 may perform an image compensation process to minimize the deterioration of the image quality of the captured image due to the blooming phenomenon. Here, the image compensation processing operation may be applied to a variety of known techniques.

For example, the digital image processor 421 scans the entire frame region of the photographed image, and when a specific region with an abnormally high luminance level is detected, determines that a high-luminance subject exists in the specific region. Various image compensation processing operations may be performed, such as reducing the luminance level of the region to be similar to the luminance level of the peripheral region.

According to various embodiments of the present disclosure, an image capturing apparatus and method may temporarily read out a sub frame first before reading a main frame from the CMOS image sensor 411. It can be provided by the digital image processor 421.

The digital image processor 421 may perform an image compensation processing operation on the main frame, which is provided later, based on the sub frame more quickly and efficiently. Here, the subframe is a name for distinguishing from the main frame, and may be variously referred to as any other name such as, for example, a pre-frame.

7 is a flowchart illustrating an image capturing method according to various embodiments of the present disclosure. Referring to FIG. 7, in operation 701, the image capturing apparatus may be included in various types of electronic devices such as, for example, a smart phone. When the preview mode is set in the smart phone, the image capturing apparatus may perform an image capturing operation of the preview mode in which a subject is photographed in real time and a captured image is displayed on a display screen.

For example, the row driver 412 reads out the pixels from the top to the bottom of the CMOS image sensor 411 in a predetermined sequence of columns by using a global shutter method. You can output the main frame.

In operation 702, the digital image processor 421 may perform an image processing operation on the main frame and scan and analyze a captured image corresponding to the main frame. In operation 703, the digital image processor 421 may operate. The controller may detect whether a high brightness subject exists in the captured image.

Here, as the method of detecting the high-luminance subject, various various known techniques may be used. For example, if a specific region having an abnormally high luminance level is detected by scanning the entire region of the captured image, it may be determined that a high-luminance subject exists in the specific region.

In operation 704, the digital image processor 421 may set a light leakage mode newly defined in various embodiments of the present disclosure when a high-luminance subject exists in the captured image. Here, the light leakage mode is a name indicating an operation mode for compensating for light leakage caused by photographing a high-luminance subject, such as a light source, and may be variously referred to as any other name.

On the other hand, if a high brightness subject is not present in the captured image and the light leakage mode is not set, the row driver 412 reads the pixels from the top to the bottom of the CMOS image sensor 411 in a predetermined sequence of columns. By out, the main frame may be output to the digital image processor 421.

In operation 705, when the high brightness subject is present in the captured image and the light leakage mode is set, the controller 422 linked with the digital image processor 421 may control the row driver 412.

In operation 706, the row driver 412 may arbitrarily change the readout timing of the CMOS image sensor 411 so that the subframe may be temporarily read out first before the main frame is readout. Here, the readout operation of the main frame and the subframe will be described later in detail with reference to FIGS. 8 to 14.

In operation 707, the digital image processor 421 may receive and temporarily store the subframe read out before the main frame. In operation 708, the digital image processor 421 may read a main frame after the subframe. You can check if it is out.

In operation 709, the digital image processor 421 temporarily stores the subframe, and when the main frame is received, the digital image processor 421 compensates for a specific area of the high luminance subject included in the main frame based on the temporarily stored subframe. Compensation processing may be performed.

For example, before receiving the main frame, the sub-frames are first analyzed to preliminarily predict whether or not there is a high luminance subject such as a light source in the main frame, and a specific region in which the high luminance subject exists. Based on the prediction result, an image compensation processing operation for a specific region of the high luminance subject present in the main frame may be performed quickly and efficiently.

Here, various embodiments of the present disclosure do not directly limit an image compensation processing operation of the digital image processor 421.

In operation 710, the digital image processor 421 may repeatedly perform the above operation until the end of photographing is requested. Here, some of the operations performed by the digital image processor 421 may be performed by the controller 422 instead, and the controller 422 may be linked with the digital image processor 421 or included in the digital image processor 421.

8 is a timing graph of exposure and readout for reading out a main frame of the CMOS image sensor 411 according to various embodiments of the present disclosure.

Referring to FIG. 8, in order to normally read out one main frame from the CMOS image sensor 411, an exposure time 801 determined as a predetermined first time must be maintained, and then a row defined as a predetermined second time ( row) The lead-out time 802 per unit must be maintained.

The exposure time 801 of the first time may be determined as a time required for each pixel of the CMOS image sensor 411 to be exposed from an exposure start time point to convert an incident optical signal into an electrical signal.

The readout time 802 for each column of the second time period may be determined as the time required to read out each pixel in rows in a predetermined order from the top to the bottom of the CMOS image sensor 411. have.

For example, by sequentially reading out the pixels of the first column arranged at the top of the CMOS image sensor 411, and sequentially reading out the pixels of the second column arranged at the top, Since each pixel of the last column arranged at the bottom is read out, the readout time for each column unit may be expressed as a graph of a gradually decreasing slope, as shown in FIG. 8.

Here, the readout time for each column of the second time may be referred to as a readout time for each line, and may be determined to be relatively shorter than the exposure time of the first time.

9 is a timing graph of exposure and readout of one pixel for readout of a main frame of the CMOS image sensor according to various embodiments of the present disclosure.

10 is a timing graph of exposure and readout of all pixels for reading out a main frame for the entire area of the CMOS image sensor 411 according to various embodiments of the present disclosure.

As described above with reference to FIG. 5, each pixel of the CMOS image sensor 411 includes a photodiode 501, a storage diode 502, a floating diffusion capacitor 503, a first reset transistor 504, a second reset transistor 505, and a first transfer transistor. 506, the second transfer transistor 507, the selection transistor 508, and the like. The plurality of transistors may be selectively turned on / off according to a control signal applied by the global shutter method of the row driver 412.

Referring to FIG. 9, the first reset transistor 901 may be turned on / off S1 at a predetermined cycle to initialize the pixel, and the photodiode may convert an optical signal incident after the initialization into an electrical signal. Can be.

When a predetermined exposure end point is reached, the first transfer transistor 902 may be turned on / off S2 so that the electrical signal converted by the photodiode is transmitted to the storage diode.

Here, immediately before the first transfer transistor 902 is turned on / off S2, the second transfer transistor 903 and the second reset transistor 904 are first turned on / off S3 and S4, so that the noise component stored in the storage diode and the like can be obtained. Can be removed in advance.

For example, before the electrical signal of the photodiode is transmitted to the storage diode, a noise component due to heat generation may be stored in the storage diode.

As shown in FIG. 9, when the second transfer transistor 903 and the second reset transistor 904 first turn on / off S3 and S4 immediately before the first transfer transistor 902 is turned on / off S2, Noise components can be removed by transmitting to the floating diffusion capacitor.

After the electrical signal of the photodiode is transmitted to the storage diode, the second transfer transistor 903 and the selection transistor 905 are turned on / off S5 and S6 to transfer the electrical signal stored in the storage diode to the floating diffusion capacitor. Can lead out afterwards.

Here, the on period S5 of the selection transistor 905 is a relatively wide period including the on period S6 of the second transfer transistor 903, and the second transfer transistor 903 and the selection transistor 905 are on / off S5 and S6. The viewpoint is applied to each column unit of the CMOS image sensor 411, and each column is read out from the top to the bottom of the CMOS image sensor 411 in order of rows in a predetermined order. For each unit, time points at which the second transfer transistor 903 and the selection transistor 905 are turned on / off S5 and S6 may be set differently.

For example, as shown in FIG. 10, the second transfer transistor and the selection transistor are turned on / off to perform readout in units of columns while descending from the top to the bottom of the CMOS image sensor 411. The viewpoints S5 and S6 may be represented by a graph of a shape gradually shifted from left to right.

Therefore, in order to normally read out one main frame, a predetermined exposure time 1000 is required, and then a readout time 1001 for each column unit gradually shifted from left to right is required.

11 is a timing graph of exposure and readout for readout of a main frame and a subframe of the CMOS image sensor according to various embodiments of the present disclosure.

Here, since the readout operation of the main frame has been described in detail with reference to FIGS. 8 to 10, only the readout operation of the subframe will be described in detail.

Referring to FIG. 11, in order to read out one subframe from the CMOS image sensor 411, the readout 1103 operation of the subframe should be completed before the end time of the exposure time 1101 determined as the first predetermined time. do.

For example, the readout operation of the main frame is completed by completing the readout operation of the subframe before the minimum necessary time td necessary for inputting a command for controlling the readout direction and the start time of the mainframe. Do not affect anything.

The row driver 412 may select only odd-odd or even-even pixels of the CMOS image sensor 411 to intermittently read out the sub-frame, or intermittently read out the CMOS image. Only pixels of a column of a specific section of the sensor 411 may be selected and intensively read out.

The readout time 1103 of the subframe should be completed before the minimum required time td and may be determined as a predetermined third time 1103 that is shorter than the readout time 1102 of the main frame determined as the predetermined second time.

Here, the readout time 1103 of the subframe may be expressed as a graph of a slope that decreases more rapidly than the decrease slope of the readout time 1102 of the main frame.

Here, since the readout operation of the main frame has been described in detail with reference to FIGS. 8 to 10, only the readout operation of the subframe will be described below.

Referring to FIG. 12, the row driver 412 not only controls on / off S5 and S6 of the second transfer transistor 1203 and the selection transistor 1205 to read out the main frame, but also reads the subframe. In order to turn out, the on / off S7 and S8 of the second transfer transistor 1203 and the selection transistor 1205 may be further controlled.

Here, the second transfer transistor 1203 for reading out the sub-frame and the on / off S7 and S8 of the selection transistor 1205 are performed to read out the main frame as shown in FIG. 12. The transfer transistor 1203 and the second reset transistor 1204 should be performed before the on / off S3 and S4.

An on period S8 of the selection transistor 1205 for reading out the subframe is a relatively wide period including an on period S7 of the second transfer transistor 1203 for reading out the subframe.

When the second transfer transistor 1203 and the selection transistor 1205 are turned on / off S7 and S8, they are applied to each column of the CMOS image sensor 411, and each pixel is arranged from the top to the bottom of the CMOS image sensor 411. In order to read out the data in units of rows in a predetermined order, on / off S7 and S8 viewpoints of the second transfer transistor 1203 and the selection transistor 1205 may be set differently for each column unit.

Referring to FIG. 13, the row driver 412 rapidly reads out a subframe by reading out the columns of each pixel arranged from the top to the bottom of the CMOS image sensor intermittently (eg, 4 column intervals). You can lead out.

In this case, when the second transfer transistor and the selection transistor are turned on / off S7 and S8 to read out the subframe, they are differently applied in units of columns, and thus, as shown in FIG. 13, from left to right. It is gradually shifted to, and can be expressed as a graph of a steep slope compared to the lead-out of the main frame.

The readout time 1302 of the subframe is included in an exposure time 1300 in which each pixel of the CMOS image sensor converts an optical signal into an electrical signal, and does not overlap with the readout time 1301 of the main frame.

Referring to FIG. 14, the row driver 412 intensively reads out a specific region (for example, columns arranged at the center) of columns of each pixel arranged from the top to the bottom of the CMOS image sensor. The subframe can be read out quickly.

In this case, the time points at which the second transfer transistor and the selection transistor are turned on / off S7 and S8 to read out the subframe are differently applied in units of columns only in the specific region. As shown in the figure, the shift is gradually shifted from the left to the right and may be represented by a graph having the same slope as the lead-out of the main frame.

The readout time 1402 of the subframe is included in an exposure time 1400 in which each pixel of the CMOS image sensor converts an optical signal into an electrical signal, and does not overlap with the readout time 1401 of the main frame.
